Oops! In my last post about this I said you could vary your rpm via
choice of wheels. What I meant was you could vary your sfpm as
needed. The 8" Harbor Freight grinder I referred to has a 3/4 HP
motor. Some of the flea market motors are 1/2 HP or less.
Judy referred to buying a purpose built setup for $200. I checked
and the decent, fairly heavy duty units are about $700 to $1000 now.
For a DIY budget, $100 for the motor and spindles, $75 for materials
(wood and PVC) to build a hood or two small ones (one for each side)
and $50 for a shop vac or shop vac motor and filter. About a day to
put it all together (eight to ten hours). The difference in price is
$700-$225=$475, so your time goes at $47.50 to $60/hr. I guess some
of you are making more than that and should go on and buy a unit. I
don’t make that much and think I could actually do it in less time
once I spent some of my TV time noodling out a plan. Oh, and I forgot
the shipping and taxes, so maybe you’d better be making more than
$60/hr to justify the purchase. But diff’rnt strokes, eh?
Don, I hope you’ll post on what you decide to do. You Meixner boys
are always interesting.
