SAILBOAT RESTORATION Log-In to Post/Reply
Hey all,

I am fixing up an 88 model Lido 14 w/wooden cb, rudder, and tiller. All wooden components are sanded. My question is should I seal/coat them with a "spar type"varnish, poly, or an epoxy of some sort?

Secondly-the Lido has a specific cb arm that is rivited together through the cb itself. I am scrapping the old board, but have to salvage this arm to install onto the new cb. How do I remove the rivits, and then what is the procedure to re-rivit it to the new board?

Any comments or advice would be welcome!

Thanks

You need an electric drill and a bit. The bit should be the same diameter as the rivet flange (probably 1/4" or 3/8"). The rivet barrel will keep the drill centered as you will drill off the flange from the barrel. Go slow and as soon as the flange separates from the rivet, stop. If you drill too far you will damage the strap on the CB arm. Then take a punch or piece of rod and knock the rivet out.
Good luck.

From Virginia Jones:

Once a piece of wood is prepped (if new, planed and sanded; if old, all old finish removed and sanded) it should be sealed. Depending upon the ultimate finish -- and there are a lot of new clear finishes on the market, many very high tech -- either use the recommended sealer or a thinned down coat of the product that you select. The best advice is to read the instructions on the container once you select your finish. And follow the instructions. If they recommend using a specific thinner use that, if they direct thinning with "paint thinner" consult with your local marine store and use what they sell. If the instructions direct you to sand (and wipe down) between coats do so. Normally yachting magazines have articles about how to do similar small projects. Or you could actually try searching the internet.

As to the pin or rivet through the centerboard and centerboard trunk...someone on the FORUM has posted instructions on how to deal with getting it out. Alternatively you could take it to your local friendly boatyard and they'll be able to get the old pin out and replace it...it isn't a big job and shouldn't cost much. Remember your boatyards are probably struggling with economic issues and can use even the smallest of jobs. Support them and they'll be there when you have a really big job!

To remove the old bronze arm, simply drill out the old rivets with a 3/16 or 1/4" drill bit. Start at the peened over end, not the flat head. They should wiggle free pretty quickly. Remove the pieces and clean up any sharp spots.

Then place the arm over the new board. Make sure it fits well, it might take a little trimming or rounding of the edge of the board to get the arm to lay up tight against the sides of the board. When you're happy with the fit, sink one screw in the top of the arm to hold it while you lay out and drill the new holes through the board for the rivets. Use a 1/4" drill bit and drill through the board making sure you drill straight so when you place the plate back on the holes line up. If this is the first time the arm has been removed you'll probably need to counter sink the mounting holes on the arm side to accept the 1/4" rivets. Go slow and only remove enough material so the rivets sit flush.

Now assemble the two halves of the arm and the board. Place the rivets in and mark them so they have 1/8" or so sticking up from the plate side. Remove the rivets and trim to that length.

Now it's time to assemble and peen over the rivets.

Place the board on a bench or on the concrete so the flat portion of the rivets are against something hard that won't give. I use a block of steel and place it up against the rivet head. Use a ball peen hammer to peen the rivet shank down. Hit the shank towards the side rounding it over. Continue until it's nearly flush with the plate. Repeat on the other three rivets. Now sink the final screw in the top of the arm and you're done.

Good luck,

Steve Schupak
