Jaysen's V12 -- 'Lil Bit' of everything fun

Not sure without seeing it but could you kerf it enough to pull it straight? Use a 2x or something to hold it straight and then fill the kerfs and glass over it Pictures will help but I could be way off base here either way.

Post a pic. Epoxy fixes anything.

Wood flour, silica, non-slip additive, 10 woven and ... drumroll please ... FAST HARDENER!



Back to real business... on the table I can see that it's actually "twisted". I think it's more that' the bend is along a plane the runs diagonal through the rudder. I'm also not sure if the bend is flat on the plane of the rudder. It seems a little more conical. When "high spot down" there is rocking on multiple corners. Here's the photos.




I was thinking about the kerf idea. The S.O.B. tool doesn't make much of a kerf. A jig saw isn't real good at not cutting all the way through a board. I'd pull the router but I think the kerf would be too large without a 1/8" downcut bit. That would leave a clean surface but is not good for a rabbit cut like that.

In looking through the scrap pile I don't have enough 3/8 to make a rudder per plan. I'm also thinking that making a cassette style lifting rudder changes the need for shape/thickness. I straight blade would make the cassette easy to make. Not sure on the thickness but math would suggest that the cassette would add stiffness to a thinner blade.

Luckily I have other things to do today and the rudder problem can wait.

Jaysen, glad your EMC order arrived!! Have a good Sunday. Jeff

First tool that comes to mind for kerf making would be the circular saw.

[Jaysen]

Yes. But when one doesn't have one, one tends to be creative

[pee wee]

Well, next easiest would be to borrow one! You could use a hand saw, table saw, roto zip or dremel, angle grinder . . . what are the choices?

[Jaysen]

If push comes to shove I'd pull out the hand tools. Rip saw and chisel would be the fall back for me.

[Fuzz]

If you can not fix it will you just throw it away? If the answer is yes then you might as well go ahead and try to kerf it. What do you have to lose? The SOB is not the tool for this job. Surely some one near by has a curricular saw?
I got to ask.............how did you manage to warp that to start with

[Jaysen]

Never under estimate the ability of an idiot!

I've been thinking of how I did that. Here's what I've got... I think that part was unevenly supported at glue up. I had weight setting in the middle to provide pressure and the bottom was supported by the deck. In looking at old photos my guess is there was a low spot under the weight. I would verify but that section of the deck met its demise due to hurricane Matthew.

As to why I wouldn't bother... since it is a compound/complex warp (not in plane, think conical) then the kerfing and tension needed to straighten is equally complex. Kerfs would need to follow relief angles as measured from the point at the apex. While I'm sure I could model that, simply thinking about it would take me longer than building a new blade.

If all you read there was "blah blah blah" then we are on the same page. I'd use the "scrap" rudder for cleats or other things.

Now that folks are opening up the homes for the summer I'm sure plenty of saws could be barrowed. If I wasn't on "probation" from my last trip into town I could just get one. That would be the easy way out...
