I missed the original question but found some things in this
response that should be addressed.
While the tecno is perhaps a more precision piece ...
The Techno Handpiece is now obsolete. The company that manufactured
them is out of business and no one in the US has been able to get
parts for them for almost a year (we still have plenty of parts for
Buy the model with the duplex spring. The standard faro is too
long and cumbersome.
First the handpiece without the duplex is shorter than the duplex
version. Second the “Faro” handpiece is not what you want because of
the “Faro” duplex. Instead get the Foredom version which is a #10D.
The Faro duplex spring is about 6 times more expensive than the
Foredom duplex springs and the Faro spring cannot be replaced
without replacing the duplex cover which is about twice the cost
of the Faro duplex spring So when replacing the Faro duplex and
cover you will be spending almost as much as a new handpiece. The
Foredom Duplex Cover is about 1/3 the cost and you don’t always have
to replace it when the duplex spring is changed.
Keep extra duplex springs handy and learn how to change
them. It is really not that difficult to learn and if you are all
ready making jewelry I'm sure you have all the tools and ability
needed to accomplish this task. About a ten minute job with
True, but you need to be very careful not to bend the spring when
installing. A slight bend can be permanently put in the spring and
will cause excessive wear and will cause the handpiece to vibrate
Keep the connection to the flex shaft and the duplex spring
well lubed. A drop of oil at the quick release should make it
This should not be necessary if the shaft is lubricated properly.
The lubrication on the shaft will by gravity flow down into the end
of the handpiece. Never over-lubricate the shaft or handpiece.
Over-lubrication is just as bad as under lubrication. Both can
create excessive wear and heat build-up.
When the handpiece starts to bind-up or get hot it means it needs
repair. Don’t keep using it or put more grease or oil in the ends to
try and make it work again. Don’t ever use WD-40 on a handpiece or
any other kind of degreaser. Failure to adhere to this will cost you
more money in the long run. When replacing the duplex or any other
part in the handpiece use only the specified type of oil and/or
grease otherwise you will be causing more damage to the handpiece.
