Question regarding inner fiberglass skin on transom repair

[rubberbelly]

Okay, finally getting back to my project after a bit of life put it on hold. Please pardon my ignorance on what I should search on to find my answer.


It's a typical transom repair... At the moment the hull is bare and the inside skin of the transom was removed/destroyed so I could get all the rot out and also so I could repair the outer glass on the inside.

Most likely I will be using Nida-bond which is the pourable stuff.

My question is the inner fiberglass skin and I see two options and would like your thoughts on the best way forward:

1. Create a temporary inner skin, pour, then remove the temporary skin and glass it in.

or

2. Form an inner skin out of fiberglass and put it in as you would with the temporary skin (adding support for pouring). This would minimize glassing after pouring and eliminate the seperating from the pour and minimize glassing after pouring.


If there is a better way please let me know, here are my questions:

How do you keep the temporary skin from bonding to the poured transom?

Is there a good link for learning how to create a new inner skin on a bench from a template? (Specifically, do you keep the fiberglass from bonding to the surface you are working on?)

Sorry for all the basic questions, maybe I'll run to the library for a basic fiberglassing book.

Re: Question regarding inner fiberglass skin on transom repair

If you don't have inside skin, you'd be better off not using the pourable transom. If you are worried about rot from a wood transom, then use coosa. It has similar characteristics to that of wood but will never rot and you won't need to build a temp skin just to cut out to reglass, if you can even do that. Pourable transoms isn't cheap to "experiment" with as you describe which sounds like an awful lot of work and headaches...IMO.
