My T-Tech machines have a fixed vaccuum attachemnt almost touching
the cutter. no stray dust !

I agree that surface grinders are special machines and are protected
well.


and I HIGHLY agree that a beginners machine, a SIMPLE drilling table
should not cost $100.00 and should be thought of as both a limited
machine and a experiment and also a unit that will be used to expand
into a better one or be replaced.

I would wager that a cheap machine should do 1,000 boards before one
felt it was worn out. and If you do 1,000 boards, you are either old
enought to retire or can afford to buy better stuff !.
