Hey Steve, I agree with Steve. (hee hee.)

I'd pull both the bulkhead (sounds like you're there already) and the tabbing. The bulkhead adds a lot of stiffness and strength to the boat, but if it's soft at the ends, there's now way it can serve its function.

Redoing the tabs gives you the opportunity to
-use better, heavier tape (like x tape).
-make the tabs wider on both the hull and bulkhead (I've looked at my tabbing and if I were redoing bulkheads now I'd make them deeper both ways).

It will also guarantee a good bond as you'll be massaging a wet tab to the bulkhead instead of trying to force a hard bulkhead to the old, hard tab.

There should be enough other markers to allow correct positioning, even after the old tabing is ground out.

Steve's remark about using epoxy, not polyester, resin is right on.

Also (and this is the fun part) it's best to leave a little room between the bulkhead and the hull, this to avoid hard spots in the hull later. I fill the void w/some sort of goop and tab over that while it's still soft so it forms easily to the hull and tab.

Here's how I delt witht he quarter berth bulkhead on Murre: http://www.voy.com/119861/2362.html

My two cents.

Good luck.

RR

Hi all,

Thanks for the tips, I'll start from scratch.

PS: I was reading Randall's step by step rebuild document this morning at 4:00am. Lot's of good information there. It's intersting how different my M31 #55 is than Murre's, especially in the cockpit area. The later hulls (like Murre) must have incorporated some design evolution.

Thanks again.
Steve
