Bill, et all! Not what are you doing wrong… lets re-phrase that!
what are you doing right? you are on Orchid.okay? now for the problem
solving…surprise!.this still happens to me…:>)
Try and maintain a closeness to the rotating bur with your
finger-tips, do not let the cutting bur be too exposed while in the
chuck…hold the chuck very tightly as this new cutting bur has still
very sharp teeth and if you are speeding up the bur…( you mustn’t be
doing this)…this WILL ALWAYS HAPPEN !..ever…so…slowly…execute a
direct and intentional cut into the claw in question. Do not for now,
cut into the claw that is nearest to you…aha! (one solution) cut
the claw that is farthest away from you, another… aha!
Once that this new claw has been used a few times this problem won’t
happen WHY? glad you asked! the teeth will be slowly be wearing down
and the sharp crispness of the teeth will never grind around the claw
and to cause you to utter such ‘pearls of wisdom’ and use "flowerful
language! " Got another idea, ever tried using a bud bur? I mean a
simple #005 or #006 size, with a SQU number of #6 in Busch burs…I
always use them in preparing an indentation for the main purpose of a
seat-cut for the next step of using the #156C (under-cutting) bur?
I will then, and only then, use the #156C for the sole use as a
"pavillion" shaping cut. It isn’t a “Kosher”/legal idea…:>) but it
will prevent re-tipping and subsequent you using gutter
language…shame! place the stone in the claw and IF YOU WISH,
administer a 156C cut into the claw for an exact fitting for the
stone at the location of the girdle! how’s this for an early teaching
lesson on early Saturday morning @7:30 a.m. ???
If you are having any further problems @Gerald …the doctor is
Gerry, the Cyber-Setter !
woops! Bill didn’t read all of your letter, try and use a 90o angled
bur. This bur should be similar in design to a diamond. The 45o
angled thingee is TOO SHALLOW in overall “pavillion” shape. I bought
some once and gave them back to the supplier! and this ain’t brain
surgery to set diamonds, just seems that way…:>)…Gerry! (again!)
