backing plates
Chris, ? The same backing plate issue is on my list right now. (Stantions only) Having just finished re-coring the deck it is clear they should have been included originally! ? I've got a friend who has access to a punch press. I'll let everyone know how it comes out. I should be there in the next 2-3 months. ? Bill Davis Scarlett #79 chrisd4700 wrote:

¿ªÔÆÌåÓýA fiberglass product called "G10" is very good for
these applications. It is a very heavy duty and non-corrosive fiberglass sheet
that machines and cuts well. It has been used in the custom boat-building
business?for years. Comes in various thicknesses.

Jamestown Distributors in Bristol, RI has this

While I agree with Marty L. and his approach to using 1/2" plywood and epoxy coating I think that there are other alternatives to metal backing plates.? One fellow I know of makes his own out of cloth and epoxy laid up in a mold.? The last backing plate I made came from some pretty cheap cutting board material that was close to 1/2" thick.? There is also a product called Starboard that is a near equivalent to the cutting board material that is pretty expensive as it is intended for marine use.?
Use a caulk like 4200 to seat it, whatever the material you use for your backing plate. My $.02. CalebD #328 Odalisque, 1967 *** See what's new at http://www.aol.com |
On the advice of an experienced boat repair guy here in Vancouver I used a piece of .5" plywood, approx 6" x 8". I painted all edges with epoxy first to seal the wood. When I drilled the stantion holes I overdrilled them, filled the holes with epoxy, let it set, and redrilled a smaller size. He claimed that the larger plywood backing plate works better at spreading the load on a cored deck. I did this 5 years ago, and its been fine. The rest of the stantions have alum back plates, and they seem fine too! I think ss is probably overkill.
