Transom Questions

[Xjbob99]

first i want to say this forum is amazing and ive learned a ton from reading through builds. its about time to do my transom on my 1968 19-6 gull. at least thats what the title of the boat says. here is a general game plan.

should i cut my gunwales or try to take the whole gunwale cap off? after that im going to cut the deck back and cut the stringers back. what should i refill the stringers with after? after i get all the old rotted wood out do i lay some 1808 biaxial on the inside of the outer skin, or should i just bond my new core to the skin a layer of cabosil? as far as the core im going with 2 pieces of 3/4 marine plywood and going to assembly in this order- plywood-1808-3/4oz CSM-plywood clamp it and let it cure overnight does that sound correct? then im going to put 2 layers of 1808 on each side of the new core. after thats all set i plan on dry fitting the core then bonding it to the skin with a layer of cabosil. after that is clamped in and cured i going to run a fillet around the new core with some cabosil with fiber then tab it in with one layer of 1808. after that im going to put 2 more layers of 1808. as far as scuppers. my current ones are cracked and below waterline. should i put scuppers in again or leave them out?

thanks for any info and help!!!!

after looking online i found this layup. is this better than what i was originally planing?

I think either way will work, but the layup you found online looks more like what most have done here.  But most people (including me) put a layer or two of 1708 on the inner transom skin before installing the core.  And those layers on the transom skin also come up the sides a bit (6-8").

thanks for the reply!
so here is my current layup schedule:

1 strip down to outside skin sand and clean the skin
2 make up some epoxy with cabosil and fiber fillet the corners in and then lay down some 1708 on the skin.
3 lay down another layer of 1708. should i do this wet on wet. or let the first layer dry then scuff it up and lay another 1708?
4 put the core in using cabosil and clamping it and let it dry overnight.
5 fillet around the edges of the new core and lay some 1708 in while the fillets are wet
6 tab in the new core
7 another layer of 1708
8 more tabbing
9 another layer of 1708 and im done.

The transom skin is a pretty easy surface to cover, so you should be able to do wet on wet.  Your schedule looks good to me.
