Re: Bought a Rockwell 21-120 Mill. by spro » Fri Oct 06, 2017 12:43 am. As you suspected, running the 1 1/2 hp under load, may be too much. The note about quill travel; The Rockwell quill is 3" diameter, 7 1/4" long. It is wide for the R8 spindle. Down feed rack length is 3".
The Rockwell is a nice garage size mill and can do some serious work. On edit: if it look like the mill might get wet then take the motor and if possible the electrics off. Motor comes off real easy and mine the electrics too once electrical box covers were removed. 4GSR Diamond. Joined Jan 25, 2005 Location

Shell mill squaring up some chunks of aluminum for welding fixtures, was great. Always wish I had more table space but overall, nicely made machine. Mine came with 200 volt motors which is a bit on the odd side but a couple of buck/boost t- formers cured that issue.

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.

So assuming it is a nice machine, and hasn't been worked over or painted how would this machine compare to the Rockwell vertical mill that I have now. My Rockwell 21-100 is very nice and I have a considerable amount of $ tied up in the purchase of it and finding a few parts. Is it worth it to potentially replace the Rockwell with the Millrite ...
Mine is in excellent condition, the motor was shot, so I built a lay shaft transmission, increasing the 6 speeds to a now current 24 speeds (85 to 6500 rpms). I …
Feb 25, 2016. #1. Hello all, I recently came into possession of a Rockwell 21-100. It's missing the gibs and some other minor parts. Does anyone know where I could buy replacement parts. Also, does anyone know the dimensions of the table and saddle gibs? Worst case I'll buy something that is close and try to modify them.
I made up a motor mount, mounted the motor and ran the mill at about at 500 rpms for about an hour, the ran the unit at 5000 rpms for about 15 minutes, constantly checking the head temperature, hardly any temperature rise. As I have 2 other larger mills, I seriously doubt the Rockwell will ever see a end mill bigger than 3/8".

There is considerable difference in size. One has a 6 X 26 table, the other is 8 X 30. The difference between the two that really makes a difference is vertical clearance. Another import machine to look at is the Industrial Hobbies manual mill, which has a 9 1/2 X 39 1/2 table. A machine of considerable capability.
Can anyone suggest a good VFD for this mill? I have 220 single phase in my shop. I believe the motor is the original. It is a Rockwell. Specs as follows: Model # 66-530 5A 56T11D29B W 1/2 HP 208-220/440 volts 1140/960 RPM 60/50 Cycle 3 Ph 2 4/1 2 - 2 6/1 3 AMPS Frame 56-8 Type TS Class B thanks
