Power Feed For Converted Atlas Mfc Mill

Contact, yes, the original "owner" of this made model V-8 engines, and used this to machine the blocks, so lots of head-room would be necessary. My current plan is not to remove the spacer, as I can always shim up the vice if running the knee to the top does not provide the correct spacing.

Robert, is this a version of the manual you referenced? http://vintagemachinery.org/pubs/detail.aspx?id=4646
 
No. That is Atlas Mill Bulletin MMB-4, last one to cover only the "C" models (M1C, MFC & MHC). It is also in Downloads. However, it is probably adequate for your purposes as I think your machine was originally a C-model. If you will take and post a closeup photo of the Bearing M1-67 on your machine, I can confirm or correct that statement). The bearing is on the front of the Knee. The drawing in the parts manual is actually of the original M1-33 Bearing. M1-67 is longer and the middle is all the same diameter. It was modified in order to add the front Arbor Support Bar, which you have no interest in as you don't have an arbor. Pus MMB-4 still has the six pages of operating instructions (which don't apply to your modified machine of course), and whomever scanned it added as the last page a catalog page showing most if not all of the accessories that were once available for the mills.
 
I plan to be in the shop tomorrow most of the day ( a much needed day off from work). I'll try to get some more pictures. In the mean time, does anyone have suggestions on the universals? From a price perspective, I am truly considering just 1/2" drive socket universals. I might consider making them, but right now, the machine is down, so I would prefer using an existing part. I highly doubt that the RPM's will ever exceed 100. Will more likely be in the 20-60 range. max torque out of the motor is listed as 20 inch lbs. which works out to 1.6 foot lbs. Torque is not a question (except I hope it is enough to run the feed).

I recently broke the U-Joint at the bed. A member here ( LJP ) did make some for his Atlas Mill and I'll probably follow in his footsteps, I just need to find the time and get the stock!
If you search for my threads as a member, you'll see the threads I mention.. ( I'll do a search and find them and link it here - I'm bored! )

About the bottom of the page is a couple links that may help your u-joint issue.. might be good reading?

Robert, I just took a quick look at the knee bearing. It is tapered front to back and there is no place to mount the arbor support arm.
 
OK. Are you looking at M1-67 in the MMB-4? Or 10F-46? If the former, then find the cast-in part numbers on either the head or the housing. If the latter, then look at the former instead.
 
M1-67 in the MMB-4. That is the one I have. most of the body is tapered. I will try to post a picture soon.
 
OK. Then it is an M1-33. And the original machine was a B-model or earlier. The part number for either the head (probably the easiest to access) or the housing will answer the "or earlier".
