My 20 year old Baldor polishing lathe is growling a lot. I know that
I can have it rebuilt and will as there is a service shop about 7
miles away. My problem is that I need more room between the motor
and the polishing wheel and have been looking at 3/4 hp motors built
by Baldor, Arbe and others that have a 5/8" shaft and a tapered
spindle. The spindle is pulled onto the shaft by threads on the shaft
and inside the spindle. This all appears to allow for a longer shaft,
more room between the wheel and motor and a larger diameter wheel.
This would allow me to not only solve the problem of needing more
room between the wheel and motor, but also use a proper hood.
My current hood is a plywood box that I built 40 years ago. I have
always applied suction in different ways to collect the dust, try to
keep things clean (including me and my lungs) and recover any metal
included in the dust. I currently use a big shop vac and a dust
cyclone for suction and filtration. I still have a lot of dust
escaping the hood and hope that one of the tapered open metal hoods
with a 3" suction hole will reduce the amount of dust that escapes
into the shop. I have also found a near by source of 1" wide tightly
spiral sewn 6" cotton wheels that improve my polishing and don’t
produce as much duff compared to the looser wheels that I have been
using. This may also help the dust problem. I know that this is a
ramble, but I have looked into the archives and can’t find a lot
about this topic, so I am looking for pros and cons about the motor,
spindle and hood that that I describe. Keep in mind that I make
large silver cuffs bracelets. My polishing is fairly aggressive, so I
need a heavy duty motor and a lot of room around the wheel. I do a
lot of cut down with tripoli or Luxi Blue which creates the dust
problem. Any thoughts are appreciated.
Thanks. Rob
