[Public-List] Bulkhead replacement question

Sat Apr 18 09:09:38 PDT 2015

Hands down the best tool would be a Fein Oscillating multi purpose tool.  They make a bunch of different shape blades to cut almost any shaped surface.  Home Depot sells a very poor substitute - I bought one and it was a waste of money and time.  Threw it away after a while. 
Right angle 4" grinders with cutting wheels work OK also, but throw a lot of fiberglass dust into the air (and your face).  I think a couple of tool companies also make small battery powered circular saws - Bosch and Makita maybe- that might work well for cutting out your bulkhead and tabing close to the hull.  I also use a belt sander to grind down and smooth out fiberglass tabing and any rough imperfections that show up after demolition or layup.  A belt sander somehow clumps the fiberglass dust together in handfuls of heavy residue and doesn't throw it all around the boat like a palm sander or grinder does. Great tool to use in FG work.

Don't know what to recommend about replacing the wood bullhead.  I recently had a bad experience with teak plywood - the glue separated in one year old ply and the whole structure delaminated when normal marine humidity got into it.  mahogany ply gives you a nice varnished surface, Coosa gets great reviews for decks and transoms.  I haven't researched it enough to know if it works for structural bullheads. Either would work Probably, but Coosa is something worth extra investigation for your purpose just to be certain...
