GRP Seacock backing plate supplier

[Hoist]

Does anyone know of a good recent supplier of a GRP backing pad for a seacock?

something like this (48mm donut hole)



Its to fit a forespar flowtech marelon flush seacock. Just took our old one out and its been trimmed down. I would prefer to build up the inside rather than machine the new one.



thanks in advance

Never seen a backing pad for sale.
I used to make mine out of ply, predrill all required holes and allow resin to soak in on all sides and then stick in place.

You can buy epoxy grp sheets on eBay
- this was the first to come up;

Pardon our interruption...

I dare say 5 mins with hole saws of appropriate sizes would see you right.

Similarly tufnol/SRBF sheets on eBay but cheaper than G10.
