Shopsmith Forums

While on the subject of quill run out, Skip Campbell has an article on his web site from 1951 regarding manufacture of the 10er and run out on the 10er before shipment from the factory. Each 10er was checked for run out before shipment and those with over .0015" were rejected. The author of the magazine article says while he watched the inspection process, no machine exceeded .0005" and that looking at the log book over the preceding week none exceeded .001".

I have the two quills laying out on the bench but don't know which one goes with which machine. How do I know?

Within the category of "two bearing quill assembly", are there different part numbers and if there are, what are the differences?

From the outside, it makes no difference. Variations are only internal(splined shaft(s) and bearings.

I have a bearing press & think I can put bearings in. are all the quills serviceable? Are the bearing available at bear supply house or only from Shopsmith?

They are 'standard' sized bearings!

Shopsmith only list the quill assembly. No bearings or shaft parts listed. Any hints or tricks to a quill rebuild? Last year the tension spring broke on my belt sander. I tried find information and a replacement spring in the end got a new assembly from Shopsmith. maybe I can look at it next week end. back on the road for work.................

Got new bearings today, after looking at the quill this week. It looks like the shaft is strait the play is in the outer or back bearing. Got two new bearings from the locale bearing supply. Bought the best they had...
I hope this will bring things back into tolerance. Will try to post pictures. So far so easy. Although I do have a Bearing press.

I am finding about 20% of the quill shafts I test have greater than .002" runout. I discarded 7 more quill shafts this week due to excessive runout or the shaft beening bent. I have a modified headstock just for testing the quill shafts and the quills with the shaft installed.

I need more ShopSmiths... May need a shaft? do the quill tubes ever need work or is wear & damage on the bearings & shaft?

interestingly enough, skip posted a video on the subject today:
