Bill, Sand the epoxy down good with 120 grit, making sure that you leave no shinney spots. Use a good grade 1 part fast cure polyurethane that's intended for use on flooring & high traffic. Minimum of 3 coats initially. Maintenance coats later will only need to be two. Also use a satin finish rather...

John,

You most assuredly need to glass over the plywood. Preferably a layer of at least 1/16". Wood is going to expand & contract, without the fiberglass to stabilize it, it's going to check & crack through the epoxy & paint.

That's what I did with Jerry Wells' B31. I used heavy weight Formica epoxied to the hull interior, which got painted... I call that technique "Instant Fairing".

Frank, The teak assembly is screwed down to the sub-shelf with #8 screws that are bunged over. Look closely and you will find the bungs. Carefully drill or cut out the bungs without damaging the countersink hole to expose the screw heads. You can make new bungs using a bung cutter available at most ...

CaptPatrick

Frank,

The teak piece at the bottom is just a channel the the panel rests into. It's part of the lower teak assembly & doesn't get removed. Remove the screws at the transom corners & the screws up under the coaming & the panel will lift up & out.

Mikey might be saying that he'll vote for Obama in the VA Primary as a vote against Billery, then Vote McCain, (or other), in the Presidental. I've even considered that tactic on March 4th... Texas is also a "Don't ask, don't tell" state concerning party affiliation.

CaptPatrick

Mikey, The heavier the material, the thicker the high density layer is. The foam doesn't do the main work of deadening the sound, the HD layer does. The weight per sheet will be dictated by the thickness of the HD layer. Weight, from the boat's stand point isn't critical. From the standpoint of you ...

Mat side always down... The mat, which is only 3/4 oz, acts as a filler layer between the woven layer to improve adhesion & help exclude air entrapement. If you want the final top surface to be mat texture, do a last layer in mat only, using 1 1/2 oz.

John, Sorry, wasn't thinking clearly... The large tube should get the job done for all. Pre-treat all of the bolts & nuts at the same time, rather than individually. That way you minimize your waste.

CaptPatrick

John, TefGel goes a long way... You only need a surface film between the dissimilar metals. For those 6 bolts only, a single small tube will still leave you with some material left over. But be smart & buy a large tube and you'll have plenty for years to come. Remember the old Brylcreem commercial? ...

Harry, The shafts should have a toe in configuration, but you can adjust them outboard a slight amount so that the shaft will just skin by the outboard face of the rudders when admidship. That'll come in handy down the line when you have to remove a shaft & don't have to drop the rudder. Br, Patrick
