In a fit of desperation, he clutched his Jet-Mini.
 

This morning I needed to start a large unbalanced blank at below my
mini-Jet's lowest speed. Je me suis-je dit! (French for slap upside my
head) "why not use the lever that loosens the belt as a slipping belt
clutch"? It didn't completely stop the lathe, but only light pressure
on the handwheel before starting did. Then the lever ramped up the
spindle easily and smoothly. Viola!

As shown in Del Stubb's video, increasing the lever's range, adding foot
pedal control and a dowel to keep the belt from being thrown away from
the back of the pulley thus tightening the front might all improve my
Scotsman's VS/clutch, but I need it so seldom why bother?

This dodge was new to me, but if every Mini-Jet owner on rcw but me
knows about it, please yawn and forgive my enthusiasm...and my French. I
mean well.

STOP THE NG! I forgot the mandatory disclaimer. Please ignore my tip,
do _NOT clutch your Mini-Jet, no matter how much you love it. At least
not until my legal dept. ok's offering my tip for use at your own risk.
Whew! That was close.

Don't you know that very few of the NG folks appreciate the use of French or
even care to take the time to understand them!
For me, I have a full-blown boycott going in my house - no Brie, no
Champaign and no using French type words! Ha!

Arch,

A Scot would just turn the switch on and off real fast, keeping the
rpms from building up and saving electricity.

I'm married to a McAmis. I have witnessed frugality in action.

Isn't that what a Japanese turner did to control the speed of his lathe when
he demo'd at one of the AAW conferences. He used a foot switch and clicked
it on and off to give the needed momentum(?) and revs to his piece in the
chuck that was attached directly to the motor. A whole body experience? I
think he was turning some sort of toy - a balloonist?.

After a dull thud, a yawn was heard throughout rcwland and I wonder
why. :)

I'm not sure if my tip for the Jet-Mini is
well known or is just a poorly thought out and unnecessary approach to a
problem that is often discussed here; ie. slowing and varying the
speed. Maybe it was my poor attempt at humor or my disclaimer or even
possibly Ray's inexplicable response. Maybe you ladies & gentlemen
didn't wish to embarrass the crotchety ole coot. :)

Whatever. _Somebody please respond. For sure, there's no scarcity of
Mini-Jet owners or a lack of interest in a non- problem; slowing or
varying the Mini-Jet's spindle speed.

Arch,

I have a Delta Midi, not a Jet but the two are nearly identical. I read your
suggestion for slowing the lathe and have the Dell Stubs video where he
demonstrates the idea at great length. I'm sure it works but I'm not sure I
would try it. Seems like it would heat up the belt and wear it out
prematurely. And the belt is a mess to change, you have to pull the shaft
out. So I guess we need to balance the benefits against the costs. But I do
like your thinking.

I was certainly interested. And kicked myself for never having thought
of it, as I've seen the video several times.

Thanks.

It gives me to wonder. I have a Delta 46-700 that does everything I want a
lathe to do but it has that horrible Reeves drives that shakes and rattles
no matter how much I try to fix it. I keep thinking of upgrading, but as a
pure hobbyist, it's hard to justify. Maybe I should take off the Reeves
drive and do a Stubbs fix. I could always undo it if it didn't work.

Anybody ever actually try Stubbs idea??

Hi Clay,

"....eccentric English." Redundancy wastes bandwidth. ;) Anyway, I'm
glad that you married above yourself. I did too and we both hope that at
least a little bit rubbed off.

Have you got any info on that Stubbs idea? I have that same lathe and would
love another solution.
