My local ACE and Home Depot did not have any 10-32 x 2 1/2 bolts that would show a smooth surface to the pork chop (instead of screw threads). Okay, I drilled both parts out to fit a 1/4 bolt that did provide the smooth surface.
That, and straightening the control arm, brought the screw back to the centerline of the pork chop and voila! I have full range speed control again. I did have to remove some of the 'crushed' portions of the pork chop teeth, so this is not a permanent fix.
I will try more hardware dealers next week (while waiting replacement parts) for a proper sized bolt as Bill used.
THANKS again to Chris and Bill!!!

I will be happy to send you or anyone needing the bolt, washers and nut along with instructions (no charge). Just Email (
annbill.mayo@comcast.net) me with your address. Thanks.

I didn't see abnormal wear in Forrest's pork chop. Yes, it is a little to one side and an adjustment will likely cause wear to be more centered, but wear will happen.
Like JPG said, "Well lubricated sheaves are the best prevention...", but even with that wear will happen! The belt tension in the motor sheaves will see to that!
Lubrication of sheaves should be almost a religion at 10 hour intervals of operation. If you let the machine set for a while, lubrication is a good idea before starting up.

Gotta disagree re 'a little to one side' as being normal. Typical, yes, but not 'normal'.
Typical in as much as the mechanism is prone to becoming misaligned by a combination of aggressively adjusting to slower speeds and sluggish sheaves.
Notice the wear is on the side of the teeth being pushed by the wormgear when 'slowing down'.

O.K.! I'll accept that!:) Do not wish to discuss the difference between "typical" and "normal" - - However, I forgot to mention that the lubrication of sheaves every 10 operating hours should include the motor sheave assembly as well as the control sheave assembly. A real good way to get oil where it needs to be is to do the lube while the machine is in drill press position.

Normal wear occurs when proper lubrication and reasonable turning force on the speed dial are observed.
Typical wear occurs when the above two conditions are NOT met!
Proper lubrication absolutely includes the motor (floating) sheave.
I agree nuf said!

Okay, not to re-open an old thread, but I gotta ask, what is the best lubricant to use on the speed control dial planetary and the pork chop gear?
I cleaned off a lot of old dried grease but would rather hear what you learned fellows use.

On the pork chop gear I'm using wax from a toilet bowl ring and on the speed control it's suggested to use a silicone spray. And no I DO KNOT mean use WD40.
