ok got the crap off the skin of the transom, ready to fit, I was wondering after i cut the transom and fit it there is a little bit of a gap in certain areams around the endge. About quater inch i would say to no more than half an inch in the biggest area. Is this fine? or do i have to do yet more cutting?

Re: fitting transom core

well i bought another one cause my other was starting to go, but then it started working again, so other than that its been no kinks. got all the wood out of the transom and am not custom fitting the dang core. its been a chore lots of in and out of the boat to get it right. but its 89% there

Re: fitting transom core

A big piece of cardboard, or drop the transom in, put a marker on a spacer, and drag it across the inside keel, marking the transom.
That will give you the profile, just lower it down to the edge.

If I'm reading correctly what you're trying to achieve......

Your cardboard template won't be perfect when you put it in, so use a spacer (aka scribing block) at least as high as the widest gap between your keel and your cardboard. Lay the spacer (small piece of wood or something) on the bottom of the boat 1/4 inch or so from the transom, lay a pen or pencil on top of the spacer with the point touching the cardboard transom template, then drag both the pen and the spacer together as a single unit along the keel and the line you draw on the cardboard will replicate almost exactly the contour of the keel as your spacer is always touching the keel as you drag the unit. Then cut your cardboard along that line, and use it as a template and you'll have transom wood that perfectly replicates the contours of your keel.

Here's a picture example of scribing. Difference for you is that your wood scribing block will be a smaller piece, unlike this picture which is a simple straight line along the full door. Yours will allow you to follow contours as you scribe your line.

Now that was a useful Tip that I will be using to make templates for bulkheads, thanks for taking your time to explain things like this.
Simple, concise information that a novice can use to make the job easier and a better product in the end.

I too am doing final preparations for the Transom installation, if I may, can I ask a few questions;

1. What is the preferred method of adhering the fitted Transom to the hull?

2. Should a bed of thickened epoxy or "Peanut butter" be put down where the trasom meets the hull/keel in order to fill the small gap that will be there?

3. What method is best for sticking the two Transom halves together?

4. I know to thoroughly coat all new wood with thinned epoxy, especially the edges, but what do I use to thin the epoxy?

I hope my questions were clear,

Yeah, I wasn't clear, just tape a spacer to the marker.

Different opinons, but mine are
! epoxy
2 yes
3 epoxy
4 It depends on what brand epoxy; google MAS , I love it, and tech support is great; the owner will call you and discuss, and check back afterwards.
Also, the MAS, before cure, cleans up with white vinegar (easier to get it off yourself, too)

Re: fitting transom core

i thought i was done ripping out old fiber glass, i noted a small piece of wood at the very bottom that i had not gotten to,so out comes the chisel and hammer....jeeze ended up ripping half the transom width of fiberglass off the transom to reveal the REAL skin. i dont know if i coulda gotten away with it as was but i removed it anyway. here are some pics, question is should i leave the little fibers? it seems that thye may help the poly get a nice bond or should i get rid of them :(
