transom repair question

[harlowcl]

I have been reading alot of the old posts on transom repair. But one question I do have is when installing the new wood, is it better to install as a complete unit, or one sheet at a time?

Re: transom repair question

it doesnt really matter, installing it in one piece allows easier clamping of the sheets together outside the boat, but if installing seperatly, you can just screw them together to clamp everything down

I think its a bit easier to laminate the sheets of plywood outside the boat then put the core in as a whole. I still prefer to bolts to draw the squeeze the core up against the transom shell. Then fill the holes with an epoxy/cabosil mix.

After the core is epoxied in, do you epoxy over it again and then fiberglass it in or do you just fiberglass it? How thick should the fiberglass be?

Chris-<br />First round all the corners with epoxy/cabosil fillets, this will help the core fit more snug. Let this dry, then prepare all surfaces. Trowel a crap load of epoxy/cabosil (thickened epoxy) at the angle where the hull floor/sides meet the transom and extend it out a little further than the thickness of the transom core to be installed. Then wet a sheet of 1.5 oz mat onto the side of the wood core to be laid up against the transom shell. Then drop the core in place. The thickened epoxy will ooze out, probably enough to make a nice fillet and to fill all voids. Then screw or clamp the new core to the transom. Then you will want to lay-up, for instance, alternating layers of glass mat and woven roven. It would be easier to lay-up some DB stitchmat or plain stitchmat, instead of the alternating layers.
