Re: Dental turbine dead-end

Randy,

I went through the same steps this morning /afternoon.

However, what may be dead-ended is only the SUPER-cheap Oralsafe
dental turbine (which is probably not up to long term use anyway).
There is a company in Austin, TX. which sells parts for and rebuilds
nearly every dental handpiece. (Yahoo search on "dental turbine") A
GREAT SITE AND VERY HELPFUL ON THE PHONE! I "want" to send them some
money!

While the price for a "whole" handpiece is in the 120-200 buck range,
the generic "canister" replacement (which is the entire "guts") is
only about 40. And all it needs is a block of steel or alum with some
holes to be made functional. WELL within the capability of a
sherline, max, or taig mill.

Anyway, if you look at how these are made, it's not too tough to get
past the "dead" end, IMO...

There's also the "turbocarver" at Turbocarver.com. A savvy
industrial "investigator" can pick up a lot of "needed" info from
these two sources... I know there's a dental turbine in my future<G>.

The TX site gets the basic unit built, and the turbocarver site adds
useful operation details, and helpful accessory "goodies"...

FYI, dental burrs are 1/16 shank. What the dental industry calls
lowspeed means under 20k rpm (but near it). High speed is 50K plus.
(under load)

If nothing else, these places are a good source for small high speed
bearings...

Hope this helps.

P.S. The latest posted pic (of the original mill setup)shows what
appears to be a "pyrathane-type" belt going from the mill spindle to
the "sidearm". Looks to me like they just replaced the impeller of a
dental turbine with a pulley!
