Does anyone know of a trick to threading felt buffs on tapered
spindles so that they run true?
I start with an oversized buff. Get it on the mandrel as best I can,
then file it down carefully ay high speed. This will cure the
out-of-balance condition. After that, the buff is left on that
mandrel until it is too worn to be of use. You can also borrow some
ideas from the carvers: Get a small piece of maple or lemonwood or
pink ivory from a wood-turning hobbyist supply shop. Cut a slice
about half an inch thick. Using a hole saw, cut a round piece of a
diameter you feel appropriate, maybe a little larger. With a drill
press, cut a 5/32 to 7/32" inch hole at the approximate center.
Using a STEEL 3/16 to 1/4" bolt, screw on a small nut, your wooden
disc, than another nut to tighten it down. Make sure you have the
hand tool set to rotate in a clockwise direction looking from the
tip of the tool towards the hand piece. This will make sure the nut
does not spin off and become a projectile. Clamp ypour hand piece in
the vise, horizontally, turn it on medium speed, and use a fine wood
rasp to turn the piece of wood true. It is now balanced. Then, soak
the wood in olive oil for a couple days. Now, apply a paste of 3000
grit diamond dust/olive oil to the wood. As you use it, it will take
up more diamond grit, using it a medium slow speed. Once it becomes
Charged, it will be very effective, last a long time and need
Or you can do the same starting with an over-sized buff, various
diamond grits do an excellent polishing job on gold and silver, but
they will also cut quickly if you don’t watch it.
In my shop, we polished all 14 yellow with a soft buff to which a
light mixture of oil and 14,000 grit diamond had been
applied…very sparingly. Super polish, super fast. I don’t know
why more folks don’t use diamond, it works quickly.
