You're almost at 1,000 subs, congratulations. I recently opened a less-than-ideal product from a reputable business that left me wondering how it happened. It's impractical to fully test everything that comes off of a production line, but I have the impression that a lot of businesses have been struggling more with quality control over the past couple years, especially with the recent inflation and supply-chain issues.
Thanks Ben, yes will likely be at 1000 in a few weeks. I agree, supply chain and labor expertise shortages is really stress testing QA/QC right now. I feel bless to have the gifts to sort my own QA/QC.
I almost "pulled the trigger" on a Mark 7 about a year ago. Kinda glad I didn't now after seeing your recent videos, Tom. If I would have as many troubles with one like you have; Shopsmith wouldn't be happy with me being I work 3 miles away from their front door. Phones calls and emails don't quite have the same impact as me showing up in person to take care of "bidness".
Chad, I'm on the fence, truly. I wish I could gush out glowing accolades. What I am finding out, it that it is an excellent design, but they have needed a few tries to achieve excellent execution. But I see a pathway to a positive outcome, which is why I have not returned it.
@@woodshopnerdery And I'm guessing by now that when you contact Shopsmith customer service, by any means, that they probably say "Oh crap, it's that Purk guy, again! How much is it going to cost us this time...". Not knowing all the issues you've come across, except for what you have pointed out in your videos; this latest one with the quill came as a surprise. Especially after knowing how much Shopsmith has boasted about how great the two bearing quill is one of the best upgrades for any Shopsmith Mark V headstock with a single bearing quill. To have questionable bearings in a brand new Mark 7/Power Pro is unacceptable and inexcusable, imho.
Chad, I live a bit over 2 hours away. About a year ago, after a LONG wait I got a new Mk7. Multiple alignment issues. I wondered whether they assembled it late on a Friday … After many emails, pix, and calls I took it back to SS. Sue was very helpful. It’s now working ok, though I still have some issues.
Good on you for being able to see the problem and communicate it effectively so that you got it replaced. I would love to get a dial indicator on my old machines, I have a feeling run out is something I just work around, lol!
Thanks Grant. I think runout impact cut quality and blade life more that cut accuracy. So, you're right you can always clear up a cut after dimensioning in.
Finally, someone doing precision testing on this machine… Thank you! More of this, please-I have been debating whether to get a Mk7 for a while, but haven’t so far, largely for this exact reason: not sure whether it’s precise enough. Another issue to explore: does it lose precision after switching modes? Thanks for your videos, Tom!
Thiago, Thanks for the compliments. Glad you liked the video. So far my Mark 7 has been very precise, as long as I hold Shopsmith to their quality guarantee. So, I've had a few issues to solve to get the precision I am looking for. Any machine lose precision (the ability to get the same repeat result regardless of total accuracy) when changing set ups. With a Shopsmith we change setups more. However, there are tricks, like make all same length cuts at the same time and set up some stops to come back to previous setups.
Another informative video Tom. While I haven’t had symptoms of a problem it may be a good thing to check the run-out of my PowerPro anyway. Thanks, Jim
A bent shaft doesn’t seem likely. I mean, the amount of force required to bend it would be significantly more than would happen easily. When you said that the bearings might not have been seated properly… I thought…. That makes sense. I’ve done that before on a grinder power shaft mount. The stone wobbled like a constipated duck chasing a grasshopper on a lawn. You didn’t have to remove the bearings to replace the shaft did you? I wonder if the bearing mounts on the shaft itself were eccentricly ground? The cause has me intrigued! PS… understanding the difference in accuracy, precision, repeatability and reproducibility give you a leg up on analyzing performance problems. Don’t they?
Dave, I am glad you agree, the shaft is a pretty beef chunk of metal with only a few inches of span between bearing support. I've hear of people bending shafts while turning large bowls and getting very nasty catches. But, I think even then it is more likely that the bearings deformed. I did not disassemble either Mark 7 quill. Shopsmith sells the whole quill and nothing but the whole quill as one unit. My suspicion is that they get it complete from an over seas supplier. looking down the back end I can see "China" stamped on the bearings. Yes to your "PS" education has been my 3rd greatest blessing behind my wife and children. I hope I am sharing a little of that blessing here.
You make us nerds proud Tom. Great video. Really hitting the Mark (pun intended)! 🤣 You seem to be getting some lemons. I wonder how the quill was on the Mark 7 you returned? Seems they should of caught that in QA. Glad you continue having positive customer service experiences. Looking forward to the next video.
another excellent and informative video. Question, did the replacement shaft come with new bearings or did you use the "ntn" bearings that you purchased? thanks for sharing, Curt.
Good comparison and metrics. Though would be interested In rip performance with a proper rip blade. Also interested how both perform using a SS planer and shaper …just to put the M7 through some challenges…
@@woodshopnerdery also, if temperature is a concern and you want to monitor, there are temp-sensitive labels out there that could be applied that would indicate an unwanted rise in temp of the headstock. We used to use ‘forehead temp strips’ for kids on machine tool motors…e.g., increase above a certain temp meant either a dull cutter or a bearing problem
You would think they would check the runout when the headstock was assembled. Maybe the runout was checked, and the problem started after you started using it. Poorly lubricated bearings comes to mind. I have three steel sanding disks. None of them are flat. Close enough for but not flat.
Thank you for responding to my video relative to the Power Pro vibration and run out problem. I don't know if I want to purchase a replacement Quill orand new bearings or just replace the bearings. Can you provide me the make and part number for the bearings for the Quill and the Shaper? Thank you, Ted
Hi Ted, I'll do one better. Here is a link to Everette Davis's Bearing guide. It is the most complete set of information about Shopsmith Bearings I know of. Everette is a real friend and leader to the Shopsmith community, you might find it interesting to peruse the other information on his Google Dirve. drive.google.com/file/d/0B1p8_ycx_8A0MHdnTU9nT056UnM/view?resourcekey=0-Gevbvd6LOVmwptFgPzexcA
Can we blame the problems on Covid? Are we still doing that? :) I wonder if it’s just low quality bearings. I’ve had that issue with my Shopsmith bandsaw.

As some one trying decide between used or new i love this content. Thanks man.

@@woodshopnerdery I wonder how many folks notice & have your patience? Again, thanks for your time and dedication.
another excellent and informative video. Question, did the replacement shaft come with new bearings or did you use the "ntn" bearings that you purchased? thanks for sharing, Curt.
Thanks Curt, the new quill comes 100% assembled. In fact Shopsmith only supplies the whole quill not the parts
Good comparison and metrics. Though would be interested

I think the quill started fine. My best guess is that there was something wrong with the bearings and the broke down very quickly.

My best guess is that the bearings were faulty and went bad as I built the first couple projects
