Classic Australian Wooden Power Boat Association

Hey all,
I am needing to make a new Transom,it is aprox36mm thick.Am thinking 2 x 18mm thick sheets of ply epoxied together.Realising Hoop Pine is preferable is the BS1008 marine ply good for the job?
All help appreciated.

Thanks

Sounds good to me. Make sure the edges are well sealed before refitting to stop moisture bleed later under the surface.

Cool,thanks for that,I have been doing loads of research on the net re resto work ,what is suggested for sealing of timber (ply) before fitting ?
As you can see on the attached pic,the transom is toast,it had an old repair or 2(cover ups) made to it,so after a bit of digging it pretty much well turned to crap lol.

Try not to dig anymore!!! Brace what you have got and try and remove in one piece so that you can use it as a template will make a difficult job easier when refitting the new transo. Anything that needs replacing that you can keep together also should be for templates like the deck, best of luck with it!

Thanks Chivs, that's the plan, have also peeled the deck off and retained for exactly that reason.Just doing a full autopsy lol to find out what's what

I threw some flat bar braces at the holy transom today ,and using a hacksaw blade started freeing planks from the transom,interestingly,with the dodgy repairs done in the past with crack in the port side of the transom opening up it has also caused some separation in the 2nd and 3rd planks down,that have been filled with some sort of white sealant,nice !And the rest of the repair involved covering the transom with a super fantastic layer of benchtop type laminate.

I would just use varnish and lots off coats on any end grain.
Was the original solid ply or framed or sandwiched solid timber with ply ?

Hey Screwit,thanks for that,original looks to be solid timber,just had a benchtop laminate over it hiding the rot lol,hoping to be buying the new ply this week as I have abig break from work coming up and am keen to get on with it.Varnish you reckon,ok will also need to seal planks if i use ply for replacements,whats the best adhesive,epoxy stuff to glue the 2 sheets of ply together for the new Transom ?

Matt, there are a few good epoxies, I like boat coat and have had good results (as a glue) it's surprising what you can get it to stick to. If your unsure just ring the manufacturer they are full of experience and ideas. One thing I have found is that the recommended max thinning for the first coat is probably closer to the min, the thinner it is the more it soaks in and the better the grip especially in timber that may have been 'pre-soaked'

I have a week off work so the Phoenix made the list of things to be worked on.Am still knocking together a gantry to use to lift the flathead out as well as assist in rolling the hull over when required.I fitted some angle iron brackets to the main beams before the transom was moved so the new one goes back in exactly where it should,used a hacksaw blade to cut through all the the copper nails attaching planks to transom ,and it came out sweet.
