Cavitation Plate Question

[cj222]

Damn that's looking INCREDIBLE!!!

Thank you!

 

[cj222]

Damn, nice work.

Thank you!

You can always mount an electric actuator like this and throw the button on the steering wheel. Makes for and easy drive.

 

[1fastsedan]

Or mount it to the floor like this.

Yeah I was thinking I may go that route. Where can I find one of those actuators?

WOW WOW WOW, super cool looking plate design man!

I used this actuator from Progressive Automations on my Schiada project:

Heavy Duty Electric Linear Actuator (2000 lb) - Heavy Load 12/24 VDC Actuator

Quality heavy duty industrial actuators for high-force applications. Our heavy duty 12/24 VDC linear actuators have an 18-Month Warranty. Same-day shipping.

Don’t let those electric guys reel you in. Haha. Nothing better than a nicely built dual petal setup. If you are really gonna drive the boat I feel that manual plates are the way to go. From the looks of your progress so far whatever you choose, it will be awesome. Looking forward to the rest of the build.

Plate pads almost done. Just need to tap the holes. View attachment 1354413 View attachment 1354414 View attachment 1354415 View attachment 1354416 View attachment 1354417

Cool pad design and nice machining. What mill are you using? I'm curious what your process was in machining those notches and angles. Plus, you did 12! Care to enlighten me?

Thank you! I am using an old Lagun knee mill. It use to be a functional 3 axis cnc but no longer works so I have been using it as a manual machine with a digital read out to know my positioning. The real shitty part about it is that I do not have a functional quill like you would on a drill press so I have to raise and lower the table to do any drilling and countersinking. As for machining these blocks, it was all about my setups and order of operations to make these the old school way. I made a fixture block also for my setups.

I'm an outboard guy and even I like it!!! Machine work and creativity is great.

Thanks bud . I am undecided on what I am going to do lol

 

[poncho]

How hard would it be to set it up manual to get on the water and add the electric actuator later and retain both systems in case the electronics fail?
Never set up a cruiser before but I like back up systems

Sorry for the twenty questions. I see you have an angle at the front of the notch, an angle on the top and the notch angle doesnt appear to be perpendicular to the top angle. It looks like you would have had three different holdings? I'm trying to imagine the order of operations. Definitely some time involved

Haha yeah, I had 12 different setups to make these parts on the manual mill

Bad ass!!

 

[cj222]

Picked up a box of 5/8" turnbuckle goodies from a buddy of mine

 

[coolchange]

You want electric plates just replace the over ride handle with a linear actuator.
Arc path of those plates is pretty severe…

 

[vstdispatch]

Don't do it way more fun with a pedal and lockout handle u actually feel like your driving the boat

I agree 100% it's way more fun with a down pedal and when u don't want to use it lock it out with the handle way more fun to drive and u feel everything the boat is doing and are in more control then waiting on a electric motor. I get bored driving boats with nothing to do while driving but what do I know

 

[cj222]

Got all my turnbuckles mocked up. Next will be machining the 1" top bar.

 

[1fastsedan]

The comments on electric vs manual. If you "drive the boat" go manual. We've been running electric plates for over 30 years with zero issues (race and pleasure). We run the piss out of our Schiada and I love having electric plates. It works instant without thinking, just hold on and drive. User preference of course.

 

[ArcadiaBrad]

Question from a non-v drive guy. Is there a hinge point at the transom, or are you only using the flex of the metal?

It flexes the hull. There's a great write up by RiverDave on this topic.

The Down Pedal

If you are a modern day I/O boater you might not even know what a down pedal is in a boat. In V-Drives there is typically two pedals. A down pedal (or a switch on the dash or gunnel) and a gas pedal. V-Drives don't have "trim" like an I/O boat...

I think this is it

Interesting...Thank You.

This is really cool, I actually didn't realize there were so many variations of the "down pedal". I have a down pedal and lockout handle on mine and I dig the feel of constantly adjusting for the water conditions. I have to admit a button would be pretty cool though, does the actuator react quick or is it more like a trim button in an I/O?

The button is instant. I can work our Schiada over any water with a push of a button. My dad had a prop walk around his hand/arm in Parker in 88/89. So when he rigged his Schiada in 90 he had one of the first electric cav plates set ups. His left hand "gimpy" we call it, has a hard time with grip and going electric made it easier for him to race.

 

[cj222]

Made a set of 304ss control arms. Need to get a new tap, my old tap barely threaded one of these.

 

[lenmann]

Dude, do you ever sleep?

Between the rapid progress on your own float, a couple of trailers in process at any given time, and random water jacketed header jobs, you get more done in a week than I get done in a year.

Nice work by the way, thanks for bringing us along.

 

[cj222]

I do, just not a lot of sleep lol. Thank you for the compliment bud

It flexes the hull. There's a great write up by RiverDave on this topic.

Think about this for a second. Bends the stringers? Bends a v bottom? Flex’s thru the chine and transom?

 

[welldigger00]

Fellers like this guy, 025, and Len make me realize just how horribly incompetent I am. Bravo!! Incredible work!!

You got it. Did you read the article by Riverdave? Its a great write up. I guess I should have been more clear as it "bends the running surface" sorry for the confusion.

"They are basically an extremely efficient trim tab, that has the ability to add positive trim as well when they are in the up position. Picture a trim tab as dragging a plate in the water to create lift, where as a cavitation plate you can move it very little and create a ton of lift, via bending the running surface, instead of dragging something behind the boat."

Don’t need to read an article how a cav plate works. Not tryin to be a d just sayin. Didn’t want someone who doesn’t understand to be mislead “ flex’s the hull”

Good to know! My 67 Lavey has just the lockout, but the Kalawain I picked up has the left pedal/lockout. The maiden voyage if the Kalawain yesterday kinda spooked me a little as I started accelerating, the nose went way up and indeed felt like I was being dragged down from behind. Any suggestions for a new to the left pedal guy?
I guess it might be trial and error next time I put it in the water...

Has anyone seen/had fins on their cav plates??

I haven't and have no clue what they're there for...stabilization?

Flats will "slide" the ass some this would slow that down although those are deeper than I have ever seen. I am sure others will chime in

 

[Backlash]

I'm no expert but have seen a few with the fins placed out towards the ends of the plates. Like stated, to help keep the ass end from sliding out during turns.
