Moulded Keytops, problems buffing

Hi John,

I use the same arbor that I mount a saw blade on. The hole in the =
buffing wheels is the same size as the hole in a saw blade (whatever =
size hole that is). I mount the wheel on there just like I would mount a =
blade. If I'm standing at the ShopSmith, I push the motor to the far =
left and push the sliding table to the right. I do not use any type of =
table at the buffing wheel - I just stand there and run the key along =
the rotating wheel. I use the integral table to the right to set keys =
down on, but that is all - also I clamp a couple strips of wood to the =
edges of the table because the machine vibrates enough to otherwise make =
the keys walk off the table (DAMHIK). I will send you a picture =
privately - if anyone else wants one, let me know - email privately.

  Hi Terry,
  You had previously mentioned an arbour, is this something you =
assembled, or bought?
  The Shopsmith table is too high, to be used with this, as I am =
visualizing this. What do you use as a table.
  Would it be possible to send a picture of your setup?
  Thanks,
  John

    I just buffed a set of plastic keys today on my ShopSmith. I slowed =
the ShopSmith down to the "jigsaw" setting (almost the slowest setting - =
a wild guess might be 500 rpm - maybe a bit more). I used an unsewn =
buffing wheel. I used red rouge on the nastiest scratches and marks - =
the red rouge is aggressive and leaves a fine scratch pattern. Then I =
hit them all with white rouge on a similar buffing wheel and they all =
polished up bright and shiny in just a few seconds for each key.

        I also have problems in this area.

        I had thought on a softer buffing wheel, but have been unable to =
find a source. The selections available at my suppliers, are limited.=20

        Any ideas?

        I had thought on slowing the wheel down. Would that help?
