transom rebuild help

[CharlestonSC]

What are they called and where can I get some?
Mine had brass one but I couldn't salvage them.

find the one that matches what you had and bed it good with 5200 or something similar

sorry couldn't get the link to work, go to west marine and type in" thru hull fittings" in the search box.

Finished glassing the floor and transom, had to use heaters to keep the temp up at night as it has been dropping down to the 50's

How much glass did you put on? Looks good, but a little light....you shouldn't see the wood as clearly as that...what was the original skin thickness? What type of glass did you use? Also, I would probably put a few more layers where the transom meets the stringers to tie it in a little better.....thats a key element for strength in a transom and allows transfer of load to the rest of the grid.

I used 38oz plain weave with 1oz chopped strand stiched to the bottom of that, it measured .040 thick with some calipers.
I know it is thick as it took 3 gal of VE to wet out the floor and 1.25 gal of epoxy resin to wet out the transom.
I got the fiberglass direct from a mill here in SC that makes fiberglass products, it was for boat building, it was a 50'' wide 50' roll, I was suprised that you can see so clearly after resin was applided, the floor I used VE and the transom I used epoxy. So being so clear I guess that is just the good quality of the glass and resin from US Composites.
I used epoxy putty in all the gaps and used that to glue the stringer ends to the 2nd layer of the new transom.
I also used 6'' wide strips of that 38oz glass to tie the transom on the sides, bottom and around the stringer first, then covered the whole thing with one big piece of the same glass.
I think this should be very strong.
Let me know what you think.

Here is what I used the woven measure .025 thick and the chopped mat is about .012 thick
And the stiching to the woven I think adds strength.

Looks like good quality material.....and you got great wet out on the tabbing and full sheet...no bubbles......but IMHO I think one or two layers isn't enough... .040 skin thickness is light.....decks are one thing, but most transoms are .125 to.250 thick, depending on the MFG'er and boat/engine combination....what was the original skin thickness you removed? You want to match and/or exceed the OEM skin thickness.
