Here’s a cool time lapse of the first span going up.
Well, you have to remember this was 4 years ago.Holy hell, that steel must have cost a fortune. The odds and ends I buy at Industrial Metal Supply are damn pricey!
It was a Suspensions Unlimited that I crashed and it needed a new rear engine cage. You made a full length aluminum skid plate for it as wellThat was awhile ago!
What buggy did you have that I worked on? I worked on a bunch back in the day.
That green blazer is still around.
In fact, the owner recently contacted me about possibly doing a whole new powertrain swap in it. Don’t know if that will happen or not, but you never know.
Ah yes!It was a Suspensions Unlimited that I crashed and it needed a new rear engine cage. You made a full length aluminum skid plate for it as well
The rest of the shop construction would grind on for about another year, with Joel, Amy, Denise and myself working on it when we could during the long, wet winter months.
Just a day after the roof was on, I rigged up some temporary lighting using a trio of LED high bay lights I had laying around.
I pulled Ol Yeller in to take a couple pictures.
This was the most room the shop would ever have, as from this point on, it would slowly fill up-first with construction materials to finish the building, then with tools, parts, and equipment.

Throughout the following months, the roll up bay doors got installed, I ran all the water lines in the shop, and generally got everything ready to install the interior sheet metal.
By February, about half the interior sheet metal and second layer of insulation was installed and it was time to start putting some real electrical in the place.

Here’s part of the first batch of conduit and electrical parts. It’s a lot.
View attachment 1427970
At some point, I coaxed Joel back into a scissor lift-but only because this was our better, more stable one.
View attachment 1427971
By March 2021, a good portion of the conduit was ran for the first 200A panel, which is outside the building opposite the gutter in this picture.
Steel buildings are always a bit of a challenge to run conduit and make it look nice.
View attachment 1427972
By the end of April, the real lighting had been fully installed, and I had the majority of the electrical completed.

One last exterior item remained to be done, and it was too cold to do all winter-besides, we were plenty busy with everything the inside needed.
By July, the inside was complete enough that we could move back outside to address something that really need to happen before monsoon season really hit full stride-the missing rain gutters.
And so, over the course of several hot and humid summer days, Denise and I tackled installing the rain gutters.
View attachment 1427976
We managed to get all the gutters up, and the rear down spouts before the first big monsoon.
But just as we finished the front gutters-with no cutouts yet for the down spouts-the first big monsoon hit-and it was a monster!
The problem was, that rain gutter was going to fill up and likely collapse because there was no drains on it.
In a frenzy, I hopped on the rickety scissor lift in a torrential downpour, with lightning touching off all around close-REALLY close-to us and the deafening roar of thunder constantly in my ears.
Up I went, barely able to see in all the rain, and started making holes with the cordless DeWalt drill and tin snips.
Somehow I jammed through the first three holes without incident, and even managed to get the size and shape of the holes good enough to accept the downspouts later.
On the forth and final hole, the trusty DeWalt drill finally died -it gave its last breath as the last hole punched through. It was a miracle it lasted that long-it was pretty much drilling under water the whole time.
With the holes in the gutter and disaster averted, Denise and I-soaking wet-hid in the shop while the storm grew in intensity and then finally blew itself out.

By August, the second 200A panel was up and I was mostly done with its conduit and wiring. Here’s the phase converter all wired up and ready to run our machines.
View attachment 1427978
By the end of August, the building was just about as done as it was going to be, somewhere in there we got our final inspection, and it was time to start moving tools and equipment in.
Here’s how it looked. View attachment 1427981
The next thing I want to show you, is a very special vehicle that got to move into the shop after being locked up in a shipping container for five years.
It was an exciting thing to drag it out into the light of day and see it again.
I think many of you here will dig it, and if I’m not mistaken, get your attention.
My name is Ian and I am a member of GD but it's my buddy Steve (fasthijumper) who was member number 3. You've got a great memory tho, I'm impressed!Ah yes!
Weren’t you like member #3 or something over on Glamis Dunes! Ian, IIRC?
Or do I have the wrong car/person?
That there is fukkin funny!
Ok, so a slight detour from the shop construction.
I’m pretty excited to share this post.
The few of you here from the old GD.com days may remember this vehicle, its story, and may have guessed what I’m about to post.
I’d like to introduce the rest of you to Project Bronco-Denise’s 1974 Bronco, or what’s left of it.
Project Bronco is a six month long makeover that has been going on for something like 29 years now.
Here’s what it looked like when I drug it out of the shipping container it had been trapped in for several years and towed and pushed it through the mud and into the new shop.
View attachment 1428634
Even though it had crap like shop barstools stacked all over and in it, it was exciting to see it again!
Here is Denise standing next to it. It’s sitting on the bump stops.
View attachment 1428636
And here it is with the front end lifted to the limit straps. The ol horse has some serious wheel travel after I designed and built it a new suspension.
View attachment 1428637
Project Bronco is a pretty rad deal. When I have some time, and if there’s interest, I’ll post up some more pictures and some of its back story.
For now, here’s a video that’s fun.

Please say it's a disco ball and a kegerator That place is looking so cool. A remote place, time warp from the 50's, with modern stuff now to keep lights on.I heard that there might be some exciting additions getting turned on at the camp this Friday...
LOL.Given that the NEC isn't always governed by what we might perceive as being common sense or even logical, and without a doubt your craftsman ship is superb.
After noticing a few things only a fellow sparky might notice, yet common sense would approve, are you subject to the oft nonsensical whims of inspectors ?
I grew up with a father that became the International President of the International Association of Electrical Inspectors, and worked with UL to co-author certain sections of the NEC. Herb Ufer of UL, was a dear family friend and a brilliant electrical engineer.LOL.
I wondered if this question would come up.
This particular facility is beyond county inspection. I imagine they could elect to get inspected if they wanted to-but their location and very nature and age of some of the structures would make that an expensive challenge, to say the least.
The particular county that they would have to use is known to be extremely difficult to work with, and that's putting it politely.
I usually recommend customers opt for getting work inspected by whatever AHJ applies, if for no other reason it can help with their property values come resale time. It also helps keep contractors honest-there's a lot of contractors who will cut big corners if they think they can get away with it.
For this installation, that option did not make sense for them (their decision) and I actually agree.
For us, it matters little if a project is being inspected or not-we do every job as if it is, and every job is done with applicable Codes in mind. At the end of the day, inspected or not, if there is ever any sort of issue with a property, the last thing I want is for our work to even be able to be questioned-so we do it to the best of our ability and judgement, and it's one less thing for me to loose sleep over. Or at least-I loose minimal sleep over.
The Code can be a tricky thing. It's a huge legal document written in legal terms and it's not always as clear as one would like it to be. And not all inspectors or counties or AHJs see it the same or enforce the same codes the same way. And to be fair, there have been a few times in my career that I've been called out on something by an inspector and it turns out I should have been. There have been a couple of times I have been called out and had to prove myself right too. The relationship between inspectors and contractors doesn't need to be a battle-nor should it be. At the end of the day, we all want safe, reliable installations. We all live and learn and adapt.
If you see something that you question, or that you noticed and are curious about, ask me. As this is a public forum, anything I post here is subject to scrutiny anyway. And I'm not above learning something new-when you quit learning, you die.
You talking bad about Jackie McGee head ding-bat LOLI grew up with a father that became the International President of the International Association of Electrical Inspectors, and worked with UL to co-author certain sections of the NEC. Herb Ufer of UL, was a dear family friend and a brilliant electrical engineer.
When I initially started my IBEW apprenticeship I was placed with the largest ding-bat electrical contractor in Orange County. Just so happens that the King of this Ding-Batting empire was the driving force behind the introduction of Aluminum romex in Orange County.
His motivation being the railroad cars filled with the shit that he'd been given for pennies so he'd lobby on their behalf for approval.
So imagine, my boss is at war with my dad and visa versa over the struggle of him trying to lobby the OC Board of Supervisors to allow it, while my dad was fighting him vigorously to prevent it.
To make life even more interesting, it was already legal in Huntington Beach /Fountain Valley and I was roping and trimming homes with the crap daily.
18 and still living at home, this placed me in a rather awkward position as nightly dinner conversation could have easily been mistaken as the Spanish Inquisition.
Dad lost the fight initially, got pissed and retired. A couple of years later, when homes started burning in Mission Viejo, the BOS apologized, banned AL NM cable and he returned for a few more years, mostly for the extra retirement dollars and to " I told ya so" gloat.
So yeah, had a bit of experience with inspectors both before and during my almost 50 years in the business.
There was that one time that one of my dad's inspectors tried to extort a pay-off from me in order to pass my perfectly code legal tilt-up job. I got a chuckle out of that, since obviously he hadn't a clue who he was f*cking with. Needless to say, being an inspector was a very short gig for this clown.
I just appreciate your interesting contribution to RDP, especially enjoy sitting on my retired ass watching others do interesting work.
If I wanted to discuss or squabble over the finer nuances of the trade or code, I'd join Mike Holt.com. No thanks.
I will participate in some electrical threads on RDP, but learned the hard way a few years back on RDP, even helpful assistance can get you metaphorically shot in the ass, so I'm far more cautious regarding the What and With Whom.
Mostly the reason behind the question was, In '04 when we purchased our 40 acres, located in Spring Valley Ranches, Hackberry and a couple of years later when we did some extensive grading, permits and inspections weren't required. I think it was within the past five years the permitting requirements changed.
Thanks again for the entertaining thread and posts.
Essentially the same, just different names. In 1966 I was working for Baum Electric, Brian Vaughn was the owner. The comical thing is, he knew who I was, and if we ran into each other, he'd always greet me and mention "Oh, I saw your dad yesterday, be sure to give him my best". Whenever I relayed that message, my dad's response was a long string of four letter words in rapid succession.You talking bad about Jackie McGee head ding-bat LOL
Should I be getting royalties?Greetings! I have been wanting to write some stories to post up on RDP for years because I figure a lot of people here would really enjoy them.
A very few of you here may recall my stories back in the good ‘ol days of Glamisdunes.com.
The problem is putting these tales together takes quite a bit of time-something I seem to lack anymore.
Well, recent events made me decide I need to at least take a stab at sharing some of my misadventures, so here goes my first installment.
My stories have typically been about my personal experiences, and usually involve my work, and all the messed up situations I somehow find myself in, all the messed up things I find myself working on, and occasionally, the cool shit I get to do when it’s not all going to hell. I expect this story will be no different.
Sit back, relax, and I hope you all enjoy the ride!
First, a little background for context.
My wife, Denise, and I own and operate an electrical contracting business. It’s small. Really small-her and I are currently the entire company. We do everything from initial point of contact with a customer through the actual field work and everything in between. Currently, and for a number of years now, our primary focus is on off-grid solar system installations. We have had the great good fortune to work on a lot of really neat projects for a lot of really great people. We generally handle an entire installation in-house; secondary design considerations, setting the ground mount arrays, trenching, conduit, wiring, inverters, batteries-the whole job from start to finish and often a lot more than just installing the power system.
In order to do that, we have an arsenal of cool tools to enable us to punch above our weight, so to speak.
If people here seem interested, perhaps I will do a thread on our gaggle of cool tools, but in the interest of getting this story moving, lets jump into this past Mondays misadventures.
View attachment 1412356
This is how we roll out to a typical job. I drive the Freightliner service truck and tow whatever equipment we need, and Denise drives the F-350 service truck and drags along our heavily modified toyhauler that is our mobile office and living quarters.
This past Monday, after a day and a half of loading up equipment and supplies, and dealing with a lot of issues in the process, we left our home base in Fort Rock, and headed East for the Prescott area for a pretty big job up in the Mingus Mountains at a 4H camp there that is completely off grid and in dire need of a power upgrade.
It’s a job that has taken over 6 months to put together, and has had a lot of delays and hurdles to clear, so finally getting to head out and do the work was pretty exciting!
Typically, I let Denise lead and I follow, which works out well because I have a lead foot and she keeps me from going too fast. The trip went pretty well, considering that we got a late start, all the way to Chino Valley. There we began the dreaded run through all the round-abouts they have installed there. God-those get old!
We survived the round-abouts and down-town traffic and somehow miraculously managed to even stay together through all the traffic. Finally, we left Prescott Valley in our rear view and began the long pull up the mountain from Prescott Valley to the summit of Mingus mountain.
If you’ve never gone up the 89a from Prescott Valley to Mingus Mountain, you’re missing out-it’s beautiful.
View attachment 1412358
Unless you are towing big long heavy trailers, in which case, you are not missing out, as the route is one of the steepest, most winding, and narrowest paved roads in the state, and the beauty of the drive will likely be lost to you as you work to get all your crap up the road safely. The route climbs about 2000 feet in about 4 miles, with most of the elevation change taking place in the last half of the climb up.
Denise had been dreading this part of the trip due to its steep grade, extremely sharp turns, and little margin for error, so she was pretty tense by the time we started the ascent. I was able to talk to her on the CB and hopefully help her out, and fortunately, traffic was pretty light.
I wasn’t surprised when she made the whole trip up like a boss without a glitch and picked perfect lines the whole way.
It wasn’t exactly a picnic for me behind her in the Freight Shaker as I weighed close to 50 thousand pounds and the road was steep enough and the turns tight enough, that I was in the low range of the 10 speed gear box and trying to keep my momentum and speed just right to avoid too many gear shifts that I could potentially screw up. LOL.
It was with great relief that we finally hooked a right at the summit to get off the 89a and onto the backroads with less pressure!
That relief was to be short lived.
I had dropped down into second to make the turn off, and once straightened out, I picked up speed and upshifted to third on the steep hill.
And that’s when everything went to shit.
I executed what felt like a perfect 2-3 shift, hit the accelerator pedal and-nothing!
What the hell? It took me a few seconds to get sorted out as the truck was rapidly losing all forward momentum on the steep hill, but I finally realized that the engine has died.
Shit!
I radio Denise that I have a dead truck, but she has little choice but to continue on up the tight winding road to find somewhere to pull off-which ends up being a couple miles further along.
As the truck came to a stop, I stepped on the brakes to keep from rolling back down the steep hill and try to restart the engine. Not happening. I set the park brakes and got out of the truck to assess the situation.
At this point in time, it was about 2 pm, and we had been up since around 3:30 am and had a long day already behind us fighting issues with loading parts, fueling trucks, and generally just lots of frustrating and tiring delays. We had planned on being in camp-still a solid hour away under good conditions, by noon. Already late, tired, and a bit frazzled, I then found myself staring down the barrel of possibly really expensive repairs and maybe even an outrageous tow bill. It’s one of the drawbacks of such a big truck-when things go bad on the road, it’s generally really expensive.
I’m not gonna lie, I was borderline about to freak out with the full weight of what my current situation could cost and entail, and I was struggling to get my shit together and figure my way out of the current dilemma. Normally I’m pretty good at assessing, troubleshooting, and figuring out some crafty way to get out of sticky situations without too much drama or expense-but I was really nervous that I had finally come up against something that was going to really get painfully expensive.
So here’s where it all came to a halt. Stuck on a steep narrow two lane piece of blacktop with a disappointingly high volume of traffic needing to get by considering the location.
View attachment 1412359
OK. Time to figure out how to get over this. First, I tried to simply just start the truck. No dice, and after only just a couple short cranks, the batteries were too low to even turn the engine over, which was unusual. So maybe I’ve just got a charging system issue and the ECU quit due to low voltage? Alright, I’ve got a big NOCO jump box for just such occasions, so I got it hooked up and hit the starter. The engine lit right off! Yeah!! I’m saved!
Nope. As soon as the engine fired up, it then immediately revved up on it’s own, then died, and would not restart. Crap.
So is it some wiring/electrical issue? This era of Cummins M-11 have a couple known issues, a few of which I’ve sorted out on this truck. Now I’m really nervous. Wiring issues can be time consuming to sort out, I don’t have the repair manuals with me to help and don’t remember what wires were the ones to check to make sure the ECU is getting power or even how to check the fuel shut off solenoid. AAHHHHHH!!!
Just as I’m about to hit freak out mode, I happen to notice a small puddle of fuel on the ground under the fuel/water separator. What’s this?! Did the drain fitting come loose and allow the fuel system to suck air? That would certainly explain everything!
As it turns out, I have had to bleed the air from this trucks fuel system a few too many times and have that down to an art form. I take an air nozzle and connect it to the fuel tanks vent and put a little positive pressure on the fuel tank and crack all the necessary valves and fittings. And this truck has a separate hydraulically driven air compressor. Of course, the catch here is that the engine has to be running to run the hydraulics. Thankfully, I have a habit of running that air compressor at every start up to make sure the air system has pressure in case of an emergency like this, so I know I at least have some air to play with.
As soon as I pressurized the fuel system, my problem became readily apparent. The water separator drain bowl had cracked, meaning the fuel system had indeed sucked in air, causing the engine to die.
View attachment 1412360
View attachment 1412361
Simple problem, and a simple fix-if I had another separator bowl on hand. Crap. Getting one of those could be a nightmare in and of itself! I could just bypass this filter if I had the right fitting to put the inlet and outlet hoses together, as I’m pretty sure there is a second filter on the system. This could be risky though, as these type of injectors are extremely fickle and do not tolerate dirty fuel.
And I have dead batteries and a now dead jump box to deal with even if I get this sorted out.
I realize it’s time to call in some help.
I need a mechanic.
Not just any mechanic, but a mercenary mechanic.
It was time to call Monkeyswrench!
Slight problem there though-on this remote mountain summit, I had absolutely ZERO cell service!
Fortunately, this is a problem that I encounter often and happened to have the solution on hand. So I deployed our portable Victron 12 volt inverter and our Starlink satellite system. After a minute for the Starlink to boot up, and my phone set to enable calling over WiFi, I’m able to send pictures, texts, and make a phone call to RDPs very own Monkeyswrench.
View attachment 1412362
View attachment 1412363
After some discussion, Kevin and I conclude that I can indeed bypass that filter for a few miles if I can scrounge up the correct parts, and that he should come up the mountain to help me get it started again and jump the low batteries on the truck. For perhaps the first time that day, fortune shined upon me, as Kevin not only lives only a few miles from where I was broken, but was available to come bail my sorry ass out. Awesome!
About this time, the director of the camp that we are already supposed to be at happens to drive up. She didn’t recognize me at first, as we had met, but she had never seen our work trucks. I explained to her what was going on, that we should be rolling soon, and could she please relay what was going on to Denise, who presumably would be found parked along the side of the road somewhere ahead. The camp director was having her own issues, as she was guiding a 28 foot box truck in to the camp that had all the solar components that we were supposed to be on site unloading. That truck driver looked frazzled too. Seemed like everyone involved with the project was running late and having a total Monday on the top of this mountain, LOL.
I began scouring our electrical work truck for plumbing parts. LOL.
Right about then, the cutest roadside assistance ever shows up in the form of my wife, Denise, driving our Polaris Ranger. We often take our venerable old Ranger to jobs with us, as it proves invaluable in moving us and parts around jobsites that often span several acres.
View attachment 1412364
Denise, who knows me well, and who herself knows her way around solving problems and getting shit done, had unloaded the Ranger from the toyhauler, brought a cooler full of water, and a bag of snacks! I love that girl!
Her and I then found an electrical fitting that we turned into a plumbing fitting by applying a ton of Blue Monster Teflon tape, and bypassed the filter assembly. We then plugged the filter to keep dirt out, and together we ran the air hose and wrenches to purge most of the air from the remaining fuel system. Then all we could do was wait for Kevin to show up with a vehicle big enough to jump-charge the Freight Shaker enough to hopefully get it started.
Denise jumped back in the Ranger and high-tailed it back to her truck for the huge jumper cables we keep on it, and for more snacks. Shortly after Denise returned, the Monkeyswrench himself showed up to make this mess a real roadside party.
Here Kevin is doing his best Austin Powers turning the Excursion around on the narrow road to get the front of it to the front of our truck. LOL.
View attachment 1412365
The three of us then got busy final bleeding the fuel system, charging batteries, trying to direct traffic and not get run over, and getting the truck started. It took a little doing, but before long, the Cummins grumbled back to life. Once it did, it was immediately apparent that a broken fuel filter was not the only issue we had-not only was the alternator not putting out much voltage or current, but the noises coming from it clearly indicated that the front bearing set was preparing to permanently retire. Yikes.
But the truck was up and running, so we decided to get this circus moving again and that Kevin would follow us to our destination in case we had any other issues and needed more help. A couple miles up the road, we linked up with Denise who dropped in behind us, and then we had ourselves a convoy!
We eased our little convoy in the last rough miles over dirt roads into the camp without much further drama over the course of about 45 minutes. After some head scratching with camp staff as to where to park a lot of large truck and trailer in a small bit of real estate, we began to get unloaded, un hooked, un packed and our camp within the camp set up.
Kevin headed back home with whatever information he needed to procure us repair parts, as he would be returning to effect more permanent repairs the following week.
It took Denise and I till about 9pm to get everything setup and ready for tomorrows work to begin. We were both exhausted, as it had been a long, long day. Several days, actually. But we had our work trailer set up in a nice spot that was right next to the building that we would be working on. Here’s a birds eye view of our camp spot.

Tuesday promised to be a better, more productive day. Tuesday, it would turn out, was kinda a liar…
Depends.Should I be getting royalties?
This place we’ve been working at for the last several months has an amazing little pond.
I sure am glad you cleaned this up. I was getting tired of the plasma table and its assorted bullshit spilling into the bay where our backhoe livesThis past weekend I managed to get some long-delayed work on our CNC plasma table done.
It has been setup and running for months, but needs quite a bit of things done to make it a more durable and user friendly installation.
First, there was a gaggle of wires and cables strewn all over under the water table that needed to get up off the ground and organized.
I sourced some old scrap chromed exhaust heat shields and modified them into a sort of cable tray and drilled and tapped the machine frame to accept them. You can see them tucked up high on the frame here.
View attachment 1437427
Then there was this fragile looking little interface adapter box that allows the computer and machine to control and talk to the plasma cutter power unit. It was just hanging loose, so I whipped up a little bracket to mount it to the top of the power supply and clamp the cables to stop them from disconnecting or getting broken.
View attachment 1437429
The irony of having to crudely hand fabricate brackets that the CNC could make better and faster-but couldn’t because it was torn apart.
I had to disconnect all the machine control wiring to improve its cable management, strain relief, and get the cables into this old workstation I had built many years ago for a customer that then closed down and returned the station to me because he couldn’t bear to see it scrapped.
Over the years I have repurposed this workstation many times and it sure has come in handy. It looks as if this might be it’s final and best assignment.

Now all the components are centrally located and protected in the bottom of the work station, and will be easier to access and troubleshoot as well.
I still have a few loose ends to address on the workstation, but the machine is now useable. View attachment 1437433
The only bummer is, I had to do all that work just so I could do the next round of modifications to the machine. Hopefully I will get to that soon.

I don't know the max, but I saw it cut the receiver plate for a pintle hitch on the big truck. Thing was probably 3/4, with 3/4 bolt holes cut through itHow thick of material can that puppy cut?
My power unit will handle up to about 1 1/4” with edge start or if I pre drill start holes.How thick of material can that puppy cut?
