I too, have been trying to find a good quick-change handpiece. I
used to use the Faro, but while I was out of the biz for about 8
years, seems they have cheapend it. Now, I have been thru no less
than 3 Faro’s in two years. They get to where they simply don’t want
to release the shafts & are wobbly. I tried the Foredom at the
suggestion of Gesswein’s tech person, only to quickly discover it was
wobbly & also did the ‘no release’ trick. One Foredom (of the at
least two I’ve ordered) began doing this the DAY I recieved it.
Thru all this, I have been in contact with the tech people and sent
a couple back to the Faro manufacturer. They have accused me of
forcing larger shafts into the handpiece (which I am not stupid
enough to do), told me that there must be something held in the
collet at all times or the collet will have problems (which is not
mentioned in any of the literature that comes with the handpieces).
A bench jeweler friend of mine told me to just rap the stuck bur
shaft against the edge of my bench to get it to release, but I dont
really feel this is the ideal solution!
I, too, will be happy to see what handpiece(s) others suggest, as I
am in need of a smooth-running, reliable one. And p.s.- I like having
the duplex spring- I think it gives me more flexibility and helps
with the pulling on my hand…
