My new (to me) Typhoon #28, 1969 has a problem with the chain plate attachment to the hull. The chain plate is screwed to a block of tapered plywood that is bonded to the hull up against the hull flange. The bonding is about 1/8" gray very tough adhesive (polyester?, 5200?). The plywood block disintegrated from dry rot. Can I just epoxy or use 5200 to glue a new block against the hull, or should I glass over it? JH

John, I would do as you say, making a new tapered block and attachingJohn Halporn wrote: My new (to me) Typhoon #28, 1969 has a problem with the chain plate attachment to the hull.

to the hull using 5200.Applied to a clean surface and left to cure before any stress is applied it should hold like the dickins,jusy try and remove it, and you will see what the manufacture claims.I was also wondering if you could also answer some questions about your Typhoon,I have hull # 27. Dose your mast go (through) the cabin coach roof?,(all the ty's I have seen, the mast is mounted (on) the couch roof)Also do you have mahogany seats,toe rails and rub rails? normally they are made out of teak.Lastly was the bulk heads made out of solid mahogany,or 3/4 mahogany ply.This Ty (new to me also) is being restored back to it's former glory,and would be interested in some compared notes,being that we are one hull # apart.
Thanks BoB P

Re: Typhoon chain plate attachment
John,
The grey goop you see was a bedding compound that CD used years ago. The 3m 5200 should work very well for your application. I just finished a new plywood pram for Hanalei and used 5200 to mate all joints. When cured, the stuff is just like rubber! It is also very tough! If you ever want to disassemble the joint, you will have to cut it apart! Just clean off all the wood and goop and replace the wood with marine fir plywood bedded in 5200 and you should be in business. The 5200 takes a few days to cure, but that shouldn't be a problem.

September 1998 Cruising World has an article on page 78 "Ave Marina
gets new knees" addressing replacing plywood chainplate knees in a
step by step format. They made new knees, used hot glue to attach
them to the hull and using layered fiberglass cloth saturated with
epoxy firmly bonded them to the hull.
