I've looked online, but can't find a variable speed polisher that does what I want it to do.
Conceptually, it's this: A small electric motor (perhaps 1/4 HP) spinning at 1725 rpm, but controllable down to about 150 rpm, very much the way a dimmer switch works with a light fixture or ceiling fan.
On the motor's shaft, I want to install the polishing bonnet wheel; this I can figure out.
With a foot pedal, I want to control the speed of the motor, similar to a sewing machine.
Has anyone home-built a unit similar to what I'm describing?
How a bout taking a variable speed drill put a flexible long drill bit extension in it . Put your polishing wheel in the end of the extension . Put your drill on the floor in a vice and press the trigger with your foot. Just a idea.
I bought this at Harbor Freight. It's only $50 and works well.
I've looked through Harbor Freight's website, but can't seem to find it.
I'd appreciate it if you would look for any part numbers or identifying items where I could narrow down my search.
I believe the item/kit in the picture may very well be what I'm looking for.
Thank you, Mike.
For me, this works great on small areas. The shaft size it uses is 3/16" which means that a 1/4" shaft cannot be used. But, for me, I use a bench grinder with an 8" polishing wheel and Jewelers Rouge, and the flex shaft for detail work.
If you want to destroy your brass, you have a great idea! Go for it!
I agree with Larry, I try to never buff brass, unless it is in terrible shape. Try to use a chemical cleaner first.
You guys don't think an orbital buffer would be okay?
I want to be able to polish the areas too small to reach with my cloth covered pinkie.
The thought I had was to have a slow turning polishing pad or cone, satured with Simichrome or Prism, to get those hard-to-reach small areas truly polished out. Then, a clean pad or cone, slowly turning, to buff out.
Saturated, not satured!
