12L14's pantograph is interesting too. The head is smallish but capable of higher rpms, tracing over a semi completed part to finer detail.

1940 Round ram, “M” head Bridgeport.
Re: Show us your milling machine!
Whew. So much going on. Your Bridgeport looks really nice for being 1940. Later ones are all beat to heck, so somehow you got a peach.
Re: Show us your milling machine!
It came from a pattern shop where it was only used on wood. I added the Servo drive and the Trav-A-Dials.
Re: Show us your milling machine!
During rocket strikes against our troops, maybe tomorrow we talk about M heads.
Re: Show us your milling machine!
Since it has gone all insipid with antennae channels, your motor may be interesting. The "M" heads had all kinds of motors driving them but they all had to fit into a compartment within the drive pulley. I think yours may be the high speed model. The way it ends up, the higher speed heads' quills ( with proper bearings) can use the newer high speed endmills that they may have envisioned.
Re: Show us your milling machine!
Currently, I am sharing the VFD with the belt sander I built.
I have the M head also. There is a crack in the housing that needs repaired. I do have the motor for it. It's in that blue milk crate!

Hi
I picked up this almost unused Prazi 400 mill at at NAMES several years ago. It has a no 1 MT spindle, a bit light. However all my tooling for my Sherline Mill fits it. The table is one of the smoothest I have had. I did not like the belt changing so I retrofitted it with 1/4 HP Lesson 90V DC motor to go along with the Lesson DC controller I had picked up new in the box at a flea market. I have been very pleased with it and use it often. The round column has a very tight fitting key and for minor Z movements it stays put to about a .001. It does not compare with my Bridgeport but for many of the little things I make it is great. My last multiple set of parts went from the Bridgeport, to the Prazi, to the Clausing 8540 I listed earlier, and then to the lathe. A different set of cuts on each machine made making the parts much simpler!

Re: Show us your milling machine!
Hi. I like it because you described how well it works for you. I could say "Nice tight high speed vertical mill", why not? Plus you bought it at the right time. A picker would have cleaned up and sold it for twice the price. I don't hate pickers. They go all around and find things. Very knowledgeable people who try to link their finds to certain groups of folks. Somebody didn't buy it as a press, nutcracker, paint mixer or other horrible things. So the guy drives hundreds of miles and makes some money. Stuff happens like a really rare metallic hand plane. Yeh but somebody used it as a hammer. Hey, "it has a handle and didn't cost nothing." Well sweetie, oh dear.
Re: Show us your milling machine!
I got this for $500. I don’t think it was so much abused or even used much as it was aggressively neglected. It had been sitting in the corner of a guys shop here in very damp Houston, Tx. It was pretty sad looking. It was also maroon and that color depresses me to look at. I brought it home and parked it while I finished another project.,Then I took it completely apart and cleaned everything up and repainted it. I had a sign shop do a new front plate cover for me. I had some trouble with the quill feed which was the last thing to go on. Of course. I’m still tramming the column to the table but I hope to start using it very soon.
Re: Show us your milling machine!
Looks very well as you've been into it. The X table power drive goes on the left side - Many choices there. It should be substantial and even single phase, certain type of motor. People don't know what I'm saying sometimes- and that is good. The older mills' table feeds were mechanically timed to the spindles' rpm. It made perfect sense because the old motors+gearboxes weighed so much, as to cause significant wear.
