I have a PM450M, and I would like to add a power feed to the X axis. About the only one I can find, that I know will fit, is a AL500, PM833T. Measuring 17x13x12 this unit seems like overkill for my small mill. Also it has to be mounted in the vertical position, so this takes up even more room in my small shop. Is this size the norm?Does anyone have any knowledge of this type of application or something similar, or can steer me in another direction?
 
WOW! didn't realize this was such a tough question.
 
Build your own, you have a milling machine, use it to make a mounting block and a cage for the clutch. 'Find' a Ford Windstar wiper motor, and gear it 2 to 1, otherwise 6 inches a minute is too slow. 12 V VF controls are really cheap, (under $5.00) I used a 12 V auto window motor, it gives me 8 ipm, just barely enough.
 
I would think any of them can be adapted in one way or another. Ck the YouTube's videos if it can be done it's there if not try to do one and put it on there . I'm eventually going to build my own simply for monetary reasons.

Not familiar with a PM450. Is it Precision Matthews or a Rockwell mill? I searched and could only find a vintage '62 Rockwell with model designation.

How 'bout a photo and a little more info?

Please read my post carefully, I did not ask how to build a powerfeed, my problem is space.

Maybe you could build a miniature one for the mystery mill to save space??
 
What is 17x13x12” if it’s the feed that’s way bigger than my Servo 150 feed on a full size BP clone.
A pic of machine would help
 
I think I referenced my mod here on the other forum to give you a visual, but sorry, missed the detail you couldn't accommodate the stick out length for space constraints

These guys did clean retro installs on Y-axis in vertical mode, but I think larger power units?

Now what I don't know is if the smaller unit like mine be adapted vertically? It has a spur gear, not a bevel gear on the output shaft so that may be a non-starter right there. I have not seen it packaged with bevel gears & related hardware. Doesn't mean it doesn't exist but for some strange reason not as common as horizontal. Wonder why they went this route?
