My flex shaft is in the reversible direction ...."

The “reversible direction flex shaft” go my attention in the dust
collection thread … where did you get it? I have a few left handed
students, for whom texturing with the flex shaft is not easy. One
with a reversible direction would be good.

Thanks very much.

I, too, have a reversible flex shaft, and though I bought mine
locally, I know that Rio Grande carries them.

Hello Michaela,

Check out the Foredom model SR (Google for it, you’ll get many hits).
That’s the one I have and I’m glad I do. Even though I’m not left
handed I still get good use out of the reversiblity, especially on
certain grinding jobs or cumbersome set-ups where I fix the handpiece
to the bench.

Cheers,

Foredom manufactures the SR Series 1/8HP reversible flexshaft. It
can use all the same handpieces and that you can use on your forward
type models. You can find it sold at most of the equipment dealers.

Michaela,

The Foredom SR motor has a forward-off-reverse switch. Remember, only
certain handpieces should be used in reverse. The popular Foredom #
30 handpiece can be used in reverse.

Any motor can run in reverse by simply reversing the polarity. If you
disconnect the cord and switch around the “neutral” and the "hot"
wires. Make sure the ground stays the same. If you don’t wish to
alter the flex-shaft you could easily build a plug in outlet box that
reverses the polarity. I would be happy to send you a drawing.

Dear Michaela,

We carry 2 options for a reversible flex shaft, both are the Foredom
"SR’ motor. One option is the “SR” motor, shaft and sheath, you
purchase the foot pedal and handpiece separately. Or a complete “SR”
system which comes with the #44T handpiece, this is a collet type
handpiece not the typical #30 with a chuck locking mechanism.

One important note on reversible motors. Running in reverse severely
limits the tools and handpieces you can use with the system. A chuck
type handpiece can loosen while running so a collet type handpiece
is recommended, also directional cutting tools are basically useless.
Some of tools that are ineffective are, drill bits, burs and
anything that uses a screw top mandrel as the screw loosens against a
reverse rotation.

Some of the tools that can be run in reverse are, diamond burs, some
diamond drill bits, factory mounted abrasives and buffs, spilt
mandrels, wire brushes, snap on discs and rubber sanding discs (if
the disc is not threaded on the mandrel).

I hope this helps.
Sincerely,
Thackeray Taylor

The flexshaft I use at home which has the two directions (forward
and reverse) I bought from Gesswein. 1-800-243-4466.

Foredom model SR, page 346 in their catalogue.

I use the reversible direction specifically because I am right
handed and when in reverse mode, it blows the dust away from my face.

Good luck,
Laurie

Foredom makes a reversible motor. Most of our left handed students
buy this.
