Making Beading to fit a bend and having a 60° vertical profile.

[STATUE]

I have an Atalanta 26 sailing cruiser and get good advice from the AOA.

But wider knowledge is always welcome.

So, the Atalanta has a raised coachroof, a bit like the forward half of an up side down dinghy laid on the deck.

The joint - blister-to-deck needs beading in the profile outlined in the above title.

Before profiling the wood I would like to make a test shape using cardboard/plaster/resin/?/?/? .... or whatever you suggest. PLEASE.

Mould it in GRP.

I always like epoxy putty for taking small moulds - quite expensive, but very convenient

This is what I fitted to the coachroof/deck joint on my Twister about 25 years ago.

Do you mean something like that, dimensioned to suit your boat, of course?

I had it machined by Robbins Timber Ltd, Bristol. Their service was excellent.

Can you take the old ones off and use it as a template to start with - then cut roughly to fit and finish by planing, a bit at a time in the time honoured way. There is likely to be a twist in the timber needed to follow the curved shapes of the deck and cabin top around the front so not straightforward. Are you intending to steam it to fit? Or fit in pieces? Try a fit with a piece of rectangular softwood of the approximate size to start with, and make little wedges to fit as guide to the shape of the beads needed at various places along to fit coachroof and deck - or maybe Uffa Fox has been clever with the curves so that a standard profile will fit all around.

Recall that some are chamfered on the inside by about a quarter to half an inch to make easier to bend around, and bedded in a suitable sealant

Thank you everyone.

Really very helpful guidance.
