Below are photos of a milling set-up that combines a cross slide table with a milling devise that was made to use on a lathe.

My friend Kal, who lives in Timmins, put it together. It works very well. He would like to have more info on the milling attachment if anyone is familiar with it.

GA, I just bought one of these on ebay, hasn't arrived yet. There are many attachments available I think. i would like to squeeze a lathe onto the boat I am building, I doubt I'll have room for a mill of any kind but i thought the Versamil would enable me to do some milling.

G. A., if it is a versamil the guy who manufactures them posts on the PM board. Ask over there and he can give you info. I think his name is Brain. James

My buddy down the road here has one.He got his at a military sale,it came in a plywood box with every single attachment,paid $450,it was never used.

I made him a phase converter so he could use it and as a result I have the use of it anytime I need it.

I have used it setup with the grinding attachment to true up large bandsaw wheels(22-36")in place on their bearings.
I also used it to keyway the tapered end of a Aquamet stainless boat shaft that was 16' feet long,it needed a key in the taperd end that was parallel to the taper I cut.I set the mill up on the cross slide and used a woodruff cutter to cut the keyway,it did a flawless job,very,very handy tool.

That is not a Versamil, that is a Master Mill Model B, they (Master Mill) invented the portable miller . Master mill sold the rights to the smaller versions to Dumore. Dumore marketed them as Model 1, or 31 (smallest using #2 MT),Model 2,or 32 (medium using #3 MT), and Model 3, or 33 using( a Special Master taper) that threaded into the spindle.
Brian Healy is the present owner of Versamil, and has just recently aquired the rights to build larger Master Mills. I have 2 Versamil 32,s with all the attachments and 1 Versamil 33 with a 2 axis slide table.

Ahhh, my tools to buy list is too big as it is.
Last time I was at Steam town, they had the new mud ring in place on the Pennsy K4. They used some portable drilling machine that must of clamped onto the mudring, it sure made big beutiful holes. I never saw the tool.

G.A., a little off topic but, I saw the photo of an alternative to holding square stock in a 3 jaw chuck and made one for myself to replace the one I'd been using that was round with set screws.....worked real nice......thanks!

You are most welcome.

These are pictures of the master mill's spindle. To me this looks like it is an arbour in a morse taper socket. If so, how do you remove/install it?
This looks way to big to sit on the cross slide of my lathe, so I may use it like Kal does for now.
Also, does anyone have attachments for this thing?
Thanks, Paul

Hi Paul,
If, as in your pic, you have a Master mill, the arbor is threaded in, to remove a wrench is put on the hex at the spindle and smack the wrench with a medium hammer to loosen. The thread is right hand. This was Master mill's orginal mounting system, mainly because they mounted the motor at the back end of the main spindle, Versa-mil (models 31 & 32)later moved the motor mount to the upper end of the main gear box to allow a draw-in bolt to hold adapers and arbors on to the main spindle, but Versa-mil retained the older style Master mill threaded end on the Model 33.
The taper on the smaller Master mills may be Morse tapers, on the medium and larger one's it is a special taper, a Master #2(.098" per in.taper). This special taper was also used on the Series 33 Versa-mil.
Some of the arbors on the larger Versa-mil's and Master mill's, the thread was missing on the end of the taper, on those arbors were incorperated a collar machined into the arbor that had two drive pins 180° apart and two recessed cap screw holes 180° apart and 90° to the drive pins that held the arbor into the spindle.
For the next part of your question about the master mill being too big to mount to your cross slide, the compound slide is removed then using the bolts that held the cross slide, you need to lower the Master mill over top of the bolts. You need to make 2 special shoulder nuts to attach the master mill to your cross slide. These nuts are threaded to your lathe compound bolt size , these nuts are 1-1/4" to 1-1/2" long, turn the OD of the nuts down to fit in the holes in the master mill base, leaving part of the hex to wrench with, keep the length of the turned down Dia. 1/16" of an inch shorter than the base of your Master mill.
For the last part of your question "are there any attachments", well first you have to measure your "T slot dia.in the main body of the Master mill, if it is 3.975" to 4" centre to center then the Versa-mil model 32 attachments will mount to your Master mill.
If you get the Universal head, or shaper attachment you will have to make a custom drive adapter, consisting of your master mill taper with the thread on one end then on the other end is a 3/4" dia. shaft with a 3/16" key way 2"long the lenght of the 3/4" dia. shaft is 2.5" long. All other attachments use the main body to mount to only, they drive directly off the motor without going through the main worm gear drive.
How many attachments !!
3 grinding spindles, internal, external, deep hole
1 Universal head (90°)
1 High Speed cutting head (90°)
1 shaper attachment
1 indexing attachment
1 2 way slide base
One attachment exception that dosen't ues either drive is the two way slide base, this base is used for Onsite milling giving you a portable 3 axis miller.
These attachments come up on Ebay form time to time.

Jeez thanks Doug, I will try and get the arbor off today.
Well it looks like I'll have to machine an arbor with a threaded end to hold end mills, also the hold down nuts you mentioned, that should be a real test of my limited skills.
Does the fact that the arbor is threaded mean I'll only be able to mill in one direction, do i have to worry about the arbor unscrewing itself?

Yes, on your Master mill the arbor will unscrew if rotating clock wise when looking standing at the spindle. The spindle must rotate counter clock wise, I think this is why Dumore changed their design on the Versa-mil models 31 & 32. They use a cross pin and a draw-in bolt from the back side.
If you made your arbors with the shoulder ring as stated in my other post, driving with the 2 pins (or cross pin) and held in place with the 2 allen head cap screws you can run CW or CCW.
