Ovations for the innovations posted here for cutting out those pesky bulkheads.
STILL, imco the Fein MultiMaster is probably the most versatile renovation tool for our historic fiberglass boats. Not to say that it is as efficient or even compares to what can be accomplished with a smart airtool. And an innovator behind that tool.
The MultMaster is an excessively EXPENSIVE corded tool.
The 'accessory' blades are even more excessively OVER-PRICED.
E-Cut Universal Narrow and Wide 'bi-metal' blades - the dog-leg flush cutting ones - are about $50 for three.
Fein has no specific blade for working FRP. I've been using E-Cuts for fiberglass. The bi-metal aspect is for cutting thin metal and nails along with wood. Heat build up on the blades imco kills them. The E-Cuts are quite thin and that with eccessive heat may take the temper out of the teeth. Have been cutting thick glass that requires the tool to work hard. However the thin blades do surgical quality work for as long as they last.
Also, they probably aren't made by Lenox.
There is animated discussion on the net (type in Fein on google) about MM.Other cheaper competitors are appearing, Couldn't be too hard to come in cheaper - and 20 year old patents are running out. Craftsman and Bosch are two. If you think you want an oscillating cutting tool check with these first. The blades will not be interchangable. Aftermarket blade makers have been threatened by Fein with patent suits. These guys have disappeared. Those that still sell non-Fein blades for the MM sell at prices not much under the real gouge. And no Aftermarket E-Cuts have appeared anyway.
Guys in the remodel trade want $15 blades for $2 to $5. That is what they should be sold for by Fein. If the tool wasn't so good at straight IN CUTTING nearly everybody would have bailed for a cheaper tool by now. This tool started life as a get-in-the-corner triangle sanding tool, but there are better shorter triangle sanders now, its main claim these days is its ability to plunge cut straight in. At a wallet plunging price.
That's what it's good at on the boat. The E-Cut Universal Narrow is my favorite - even if they dull too rapidly.
Other useful blades are the brutal triangle handyman rasp and the ($45!)* smaller finger rasp for rough shaping of frp.
Fein could do no better than develop a few more blades for boatworkers.
Blades that will happily cut fiberglass all day (carbide?), cut aluminum and s.s. tube, and cut the ends off s.s.bolts.
A set of smaller less aggressive diamond rasps as flats and 1/2 rounds for detail work in corners.
