Re: Ball bearings

Hmmm......not anealled yet?

Well one thing that you must make sure is that the ball bearing must be
right through.  It took me about 5-6 minutes of direct heat using a propane
to heat the ball to cherry red.  I then continued to apply heat for another
2-3 minutes
and then let the ball cool off.  Please keep in mind that these were 3/4" in
and anything larger would surely take much longer...how much longer is a
of trial and error.....but isn't that what make a hobby interesting?

Yes, the balls did tend to exhibit a bit of flaking but I had no problems
drilling a hole
into the center of the ball using standard high speed steel drill bits.  I
used a lathe to
hold the ball while I drilled it.

Please contact me if you would like to see the results of the final product
after it was
drilled and polished up at     rstaron-at-aracnet-dot-net
