Hi All. I am at the rebuilding part of putting a Rockwell 21-100 milling machine back into working condition. I just picked this machine up about a month ago, it seems like it has had a good life, and has not been abused too badly. It is fully disassembled, and came apart with no real difficulty. I think it had the original bearings in it.

Re: 6 or 8" rotary table for rockwell mill. I have a 21-100, but regardless I would suggest the largest you can get away with, the main reason is you will need room for clamps and such. I would say 8" is minimum (based on the original Rockwell manual), but I have a 10" (horizontal only) Palmgren which is low profile (3-1/4") and actually pretty ...

The Rockwell 21-100 is a magnificent little mill, and you're going to LOVE it. For some jobs it's preferable to a Bridgeport. I personally needed something with a small footprint. I found lots of $2-$3k Bridgeport or Bridgeport knock off's. But I needed a small footprint and 110v would be REALLY nice since I don't need a ton of power, or table ...

Rockwell 21-100 Spindle Rebuild. Re-posting after server crash issue... I recently acquired one of these vertical mills, and will be rebuilding and refinishing it as time permits.

2/07/22 #327. I am looking to add an aftermarket X-axis power feed to my 21-100 vertical mill. Preferably without having to build half the thing myself. I know that the actual Rockwell power feeds for this mill are near impossible to come by and have seen where some folks have added feeds only to end up having to machine out half the darn …

May 10, 2015. #1. Hello again all. While testing my newly-acquired 21-100 I found that there was quite a lot of noise from the spindle assembly at high speeds. Imagine my surprise when I loosened the belt and found I could lift the pulley hub (part #22 in the Army 21-100 manual) right out of the pulley with two fingers!
