Trying to get back to the original discussion of this thread - after 10 months of trial and error I believe the solution(s) to the banging/jumping issues with bandsaw is fairly simple.
After making sure the computer in the headstock is correctly adjusted, the problem can be fixed mechanically.
Make sure the hubs between the headstock and bandsaw are perfectly aligned.
Make sure the hubs are staying tightly fixed to the shafts.
Make sure you have a coupler that fits VERY tightly with both hubs.
Make sure the headstock and the bandsaw are both tightened in place.
If there are still issues, check and tighten headstock belts and check the motor pulley for tightness.
If noises re-occur, check all of the above.
Any one of these points can come loose and again cause banging noises. The use of thread tightening items will help.
Also, you can try mounting a faceplate on the auxiliary spindle, or a sanding disk on the main spindle. These items can help, but they are overriding one of the tightness/looseness points.
For a long time I thought I was the only person experiencing these issues. I am presently relieved to see others have had similar problems and made similar corrections. I'm glad we can freely discuss the not so pleasing aspects of PowerPro use, and hopefully find ways to completely end them. Many folks have had operational issues with the Mark V and through discussion, these problems have become known and featured in the recent Shopsmith computerized efforts. Now we are doing the same concerning the PowerPro headstock.
The PowerPro is a great improvement over the older headstocks. I hope those not yet having the PowerPro will not think this upgrade is a bunch of trouble and not worth fooling with. I think back to what
non-shopsmith owners must think when reading about the multitude of issues in the old headstock that are associated with faulty lubrication. Do they think of the Shopsmith as a bunch of junk? Well, we've heard such comments!
I'm here to tell you the PowerPro is an excellent upgrade!!:D
