The guy who wrote the article (age 79) was well aware of all the problems
including rigidity. He has addressed these and other issues in very
interesting ways. He added a speed reducer unit to drive the band saw, a
Darex drill sharpening unit, and a thin saw to cut decorative inlay molding.
I read the article at my local bookstore. I was tempted to buy it. I may
subscribe just to get the rest of the series.
