Huh
If I put an old quill in a Power Pro head stock and can't/shouldn't run it at "full bore" what is the point of a Power Pro? Yes there other advantages but com'on man. 7200 RPM I thought the standard SS was 5200 RPM (5700?), half the Power Pro. Why do you think the DIY kit comes with a new quill? As had been said the part numbers have changed, sooo...
The context is important!!! This message was sent at a time and to a person regarding using an old quill to chase down (or isolate" the cause of unwanted vibrations.
Of course you are going to want to operate at 10,000 rpms with your new PowerPro. At least now and then. For curiosity, how frequently do you get up into that range with the PowerPro.
Yes, reference to 7200 is an error and should have been 5200. No change in context, however.

If you did allot of routeing with it, would you not run it near 10K rpm, revolutions per minute.

Greenie, Grayling, SS stand alone BS and BS SPT, jointer and belt sander, 3 Ers with Speed Changers. I think those 3 cover my ER needs, and space for them.

OK, but my point was about using a pre Power Pro quill in a Power Pro. You seemed it indicate that it was OK. The same as other posters in the past. I disagree. SS needs to differentiate the bearings and make sure you can't put an old quill in a Power Pro.

Yes this is the pot calling the kettle black.
So what if one runs an old quill super fast. Only the old bearings will complain. It ain't gonna blow up!
Point is(as Dusty already pointed out) that the suggestion was made to aid in understanding the original 'problem'. We be far out on a limb with this flapping.

Did you get a factory assembled headstock or did you get a DIY headstock. If you bought a complete headstock try installing your original quill and making another test. Actually whatever you bought you should have another quill to try.
You may also check the motor mounts and see if anything is not tightened properly

Was brand new, fully assembled head. Odd Shopsmith didn't ask me to try changing the quills or checking the mounts.

Whut a coincidence. Just ruminating t'other day about the quill thing. I too had a "completely new" PowerPro (or should I say I Paid for "new"?) and after the normal (then- near start of program) fixes found that the quill which I had Upgraded in my old headstock and which had been Zero runout thereafter was, of course, replaced by a "New" quill, which now has considerable- as in highly Visible, evun- runout, at least when in drill press mode. Very disconcerting, especially when using the new spiffy chuck, seeing all that (enormous) beautiful chucking hardware waving in the breeze, so to speak.
Sad.
I am unable to get through the rhetoric with out loosing the jest of what you are saying. Did you get a PowerPro and then discovered that you had "excessive runout" in the quill? Did they fix it for you? Does it work now? Do you do a lot of routing and shaping? What bearings are in a quill? Runout in the drill press mode - could be chuck.
There was at least one report of excessive run-out on the new chuck, isolated or not has not been determined. Perhaps that is what you are seeing? If you can check that out it might be the quill isn't at fault.

A 5000 RPM increase is nothing to a bearing. Years ago I serviced a ball bearing manufacture. The tests they put their bearings through were starling. They had a machine that would increase in speed RPM and pressure until the bearing failed. We are talking tons and tens of thousands RPM.
Interesting note they used an oil to lube the bearing during the test. One day they ran out and one of the techs had a can of ARRCO graphite oil in his car. They used it and found they could not destroy the bearing. The engineers were fascinated and studied the results for days.
Well, it's about 90 minutes before sunup on Christmas Day.the wife is dozing on the sofa (health issues.) I have just finished reading this thread and just wanted to thank all of you for such an illuminating discussion. I am a new owner of an old model 500 and these items are very interesting even when some of the engineering talk is over my head. I am also gratified to learn that SS is involved. The wife's father had a SS and built two homes with it. An elder brother got it when he passed. When the brother died last year, the wife suggested I offer to buy it. It is still in the family but I found one on Craig's List and you know what happened next. Shopsmith gets a lot of crap on line but so glad I found this forum. Looks to me like the company is doing its best. I'm even pleased to get the e-mail ads from Dayton.
I can't wait to see how the Powerpro issue is resolved.
Merry Christmas and wishes for a prosperous New year to us and the company too.
