rockwell mill question. by fjrrider » Mon Jan 19, 2004 8:31 pm. I recently purchased a rockwell 21-100 mill and while checking different online spec-sheets I noticed that the advertised vertical travel was anywhere from 15 to 16 inches. With my knee in its lowest position I measure roughly 11inches between the table and spindle.
Specs: ~1000 lbs. 6.5"x24" table. 16.5" vertical travel, 3" quill movement. Power feed on x-axis, spare power-feed that I can install on the knee. R8 taper on vertical head, #30 NMTB taper on horizontal. 110v, 3/4 HP motor on vertical head. 220v, 1.5 HP motor on horizontal arbor. There is no gearbox for the vertical head, just a set of pulleys ...

The other I'm looking at is a Rockwell 21-120 Horizontal Milling Machine. It is a bit more "failry priced" in my opinion. I was curious to know if the horizontal model can be modified to accept a vertacl milling head?Could a small Bridgeport head be attached to it,or would this be a HUGE/IMPOSSIBLE engineering project that I probably wouldn't be able …

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 …

Because the table is only 6.5"x 24", most accessories used are smaller than a full size vertical mill. Some accessories used are: 4" mill vise, 6" H/V rotary table, 5C H/V indexer, 5x7 tilting table. And the Rockwell has a quill with 3" of travel. ... All of the Rockwell mills are very rare, the H/V combo the rarest. If you run across ...

It will be past the end of the taper. As to whether or not it can be repaired, it depends upon how the pin was installed. Extend the quill and look for signs of the pin on the outside. If you find it, then it is repairable. John_Dennis said: I bought this mill from a guy closing an auto shop. It is an R-8 quill.
Sep 25, 2016. #4. The Rockwell mill is much stouter than the Clausing mill. They made nice mills but with a much smaller envelope to work with than a Bridgeport. Just remember, there are no repair parts available for this mill. You'll have to make your own repair parts when needed. I think $2000 is a little high, but for the area, its fair.
