: Does anyone else have suggested tools to take off lots of material fast,
: especially on an inside? Other adaptations of power to plywood
: boatbuilding?

Different brands and different versions of the same tools vary considerably in power, aggressiveness, and convenience of use. To whit, a top-notch variable- speed Porter-Cable belt sander that I use at work has so spoiled me that I can't even remember the last time I used the old Craftsman in my own shop--if I need a belt sander I borrow the one from work. Similarly I've got a B&D right-angle ROS that is much more aggressive and much less controlable than either my DeWalt or my P-C electric ROS. In between is a pneumatic DA I use at work. For interior curves you might try some sort of ROS or disc-sander with an oversized pad. Another aggressive tool I like is a small Surform (Stanley?) with a curved blade about 1.5 x 2.5 inch. Unfortunately, mine broke and I haven't found a source for a replacement. Tom
