Do it before.  Glue and fillet it in and then drape, roll the cloth over it.  Later on you'll grind an angle on it so the water can get in.

Got the drain pipe in. A little sloppy on the fillet but I smooth it out more after the pic.



After that I started laying on the biaxial. Here's the 2nd layer. I wish I smoothed out my fillets a little better. There was some bubbles I couldn't get out for the life of me and I wish I ground down the edges where it meets the dam a little better. All in all I'm pretty happy with it. It could have been better. This is my first time doing anything with glass.


And the last layer of the outside skin. Pretty low on epoxy so I'm putting in an order for 2 more gallons tomorrow.

Looks like it came out pretty good.
When you use fillets to round out the corners you want to let them start to stiffen up but not let them cure before continuing.  You want to do everything wet on wet so it is all one piece as it cures. You let them start to cure so you don't squeeze them out as you hard roll.
So just like you'll need to scruff up the glass you just laid before you proceed, there is no difference with fillets that you lay in and let cure.

originally that was my plan. but the fillets were taking forever to harden up and i ran out of time. i didnt scuff the fillets.  :38: hopefully they will be fine and have a good bond

That is the beauty of epoxy - would have been better if you scruffed them up but...
And epoxy does take a while to harden depending on what type you use, i.e. slow, medium, tropical, etc.
As the saying goes "Patience Grasshopper" :D

Well. Not much to do tonight ran out of epoxy. Order some more this afternoon. Came home and took the dam off. I gotta say I'm pretty impressed with it. Only a few bubbles but I think I'll be fun  :great02:

alright im trying to come up with a plan for next week. does this sound good.

make template and cut out new core.
its going to be 3/4 marine plywood-3/4oz CSM- 3/4 plywood. wet both pieces of plywood then lay the csm down and wet it out and lay it on the garage floor with a bunch of heavy stuff on it and let it set up.
 
next ill  dry fit the core and come up with a clamping system. once i feel that is perfected ill scuff up the outside skin clean it up and mix up a batch of cabosil and 3/4" chopped strands and 1/4 trowel it on the skin and transom core then set it in and clamp it.

once that dries and is all set i plan to lay 3 more layers of 1708. is that too many? should i stick to two?

You've been studying  :clap01:
Everything looks good in your plan. The 3/4" chopped strand is going to make it pretty messy though. I think I used cabosil mixed to thickness of peanut butter and trowelled that on the skin and then clamped it.

Hey rick,

The 3/4 CSM will be going in the middle of the 3/4 plywood. Then I'll be clamping in it the way you said

This is what I was talking about. 
The 3/4oz CSM between the transom cores is fine.
