I decided to add a little additional protection to the chine cap to prevent dings from trailer parts, scrapes on rocks, etc. So I got some thin strips of Alum to run along the bottom. My problem is now figuring out how to attach the Alum strips to the chine caps. I didnt want to use screws since they would stick out potentially causing a catch hazard. I was thinking about some small nails, but cant find something small enough that would be good in water.

Ideas?

Sorry for the lack of pics on this build, been crazy busy getting ready for Oregon this summer.

Thanks as always!

Ben:  Silicon Bronze ringshank nails might work.  They come in 3/4" and up.  Not cheap but they are common to boatbuilding.

Good Luck 

Ben, how thick is your aluminum? Could you countersink the screws?

Rick

This is a proven solution that usually uses thick enough of an aluminum strip to countersink a #8 screw so it is flush with the aluminum surface.

For a little more money you can use the half round strips of stainless that come pre-drilled.

Randy, where is this stainless steel available?

Rick

Rick,

Check these guys out .

Another choice, which is a less costly but a little more work (well, maybe more work).  A friend made an Brass rail for his wooden boat (you could do it with Alum also). He took a piece of 1/4" x 3/4" brass.   I don't know the length but he used scarf joints to butt them along the side of the boats outer shear rails with Brass Round Nead nails.

What was interesting about it was, he set up his router table and with a radiused carbide cutter, made several (many) passes with a radius cutter and turned the flat 3/4" side into a nice convex curved surface. The initail set up was done with a real light cut (outside corners) and after each pass he added a layer of masking tape to the fence and it increased the feed into the cutter a controlled amount.  I am not sure how many passes he made but the result was perfect.  After polishing it it looked as good as anything you could purchase.

Just another way to obtain a desired result.

Dorf, here is another online source. http://https://www.onlinemetals.com/merchant.cfm?pid=4387&step=...

8' x .125" x .75" = $13.56 each

I was wondering if Randy had a source close to him.

Ben,

Your could purchase a metal countersink, and use the same wood screws as used on the rest of the boat.  Aluminum is really soft.  It's also kind of sticky when in contact with rocks.  Something to consider.

I thought chine caps were meant to be replaced? wood certainly is cheap enough.  My 10 year old 16x48 runs alot of low water with awful rock gardens, it still doesn't need new chine caps.  And we're not nice to her either!

Rick,

Check with Rays River Dories in Portland for the stainless 1/2 round.

Yes, Ray's has it and you can order it from JamesTown.

It comes three ways.  light weight hollow, heavy weight hollow, and solid half round.

I'm not sure what Ray and Cyrus use.  Perhaps they will chime in here.

I used the heavy hollow half round when I ordered for my shop and I ordered it wholesale from a marine supplier in Kent, Wa. Unfortunately that's not available to everyone and I've shut down the shop for a few years.
