In a recent "New Yankee Workshop" episode Norm mentioned prefinished
maple plywood, with a very tough finish. Anyone know anything about
this, in particular where I could find a list of suppliers,
particularly in the SE Massachusetts area/

One of my local suppliers carries this. He's on the CT shoreline.

Maybe if you contact him, he can tell you where he gets it. His source
may be able to point you to a retailer in your area.

Now, back to bandsaws with multiple blades...

He was probably talking about ApplePly. It is sort of an expensive US
version of Baltic/Russian Birch made by a company in Oregon. It has
Maple faces and consistent, voidless birch plys. Available prefinished
with a very hard high gloss poly and available in some wild looking
translucent colors too.

Any commercial hardwood/plywood vendor that is supplying the cabinet
industry will carry it. Probably find it from any plywood vendor in
the yellow pages.

On a related note, a simple dado joint with prefinished plywood will
have finished surfaces adjoining the sides of the dado. When glueing
such a dado joint, is it necessary to remove that portion of the
finish?
