I want to say that HSM or MW had an article on
building a replacement base for these saws that
included both the swivel feature and a lowering/
elevating table, but darned if I can find the reference
right now. Oh, wait a minute, this might be it:

"A Modified Base for a Band Saw",
by Jim McKee, HSM 2001 Jul-Aug p.64

Thet aren't it... still looking, it's startin to bug me
that I can't find it...
