Any of us here that make bigger things need the right tools to do so
and the same applies to polishing. Can I suggest you think along the
You see a stand alone motor off some other machine opens the door to
doing what you want in a much better way than the Baldor solution.
Get a stand alone motor say 1.5hp to 3hp,. mount that under the
bench. put on that say 3 wheel pulley 2in 3in and 4in dia. To run an
A section belt.
Then have a seperate shaft on 2 bearings likewise with the same size
3 wheel pulley on it on you bench. To this you can mount the taper
threaded wheel holders what ever distance you want from the bearing.
Would 8in be enough? if you have say 18in between the bearings this
would provide the support for your heavy polishing loads. obviously
youll need a l handed threaded one on the left and a rt handed on on
the right. Also you will need to have the shaft and bearings at least
8in above the bench.
then build a suitable plywood shroud around the mop areas. To that
mount a 3in min vac hose connected to a Harbour freight vac unit
that pulls 600 cft a min air. Here in the UK there sold under the
Machine mart brand. Exhaust that directly into your own made vac bag.
I made mine from a single bed sheet sewn lengthwise(singer) and hung
length wise behind the polishing bench.
Now I made mine up to this spec and the mop/wheel height when
standing is level with my elbows. Easiest position when polishing a
big as in 18in dia bronze or silver dish.
Also youll need as in industrial polishing shops bolt the whole
apparatus to the floor. Why? cos when you push hard on the work
youll need to make sure you dont push the machine over.
Ive several built like this, from as small as in 1/2 hp with a 1/2
in shaft for mops up to 3in dia up to 3 hp with 1in shaft for wheels
up to 12in dia.!!
With this setup you then can have shaft/mop speeds from 750 rpm up
to 3500 rpm by just changing the belt over. For sanding with scotch
brite wheel 3M products at slow speed, to swansdown mops for final
finishing of silver at the higher speeds.
On the subject of tools for finishing, I also use sanding belt
machines. with belts usually 36in long by 1/2in wide, so much faster
than filing, these are mounted vertically. I buy these also by 3m
usually 4in wide, then simply tear then down, except where the joint
is! to whatever width I need. Likewise at elbow height. all used
standing up. Then up to 9ft long by 3in wide. Thats mainly for
The only work I do sitting down is soldering.
