Default My Bridgeport M-head milling machine.

I started checking a few thing tonight on the head of the mill, for one I would like to know the year of manufacture. So I went looking for the answer, the number on the knee between the was is in the 14400 range so that makes it a 1951 model.
The head itself is in pretty good condition with the original feed handle for the quill. The belt will need replaced before I do anything milling with it. But I do have the adjustable belt I bought at HF. The step pulleys look to be in good shape also. Not much I can tell about the quill and spindle until I have it back on the base.
  1. The heads data plate.
  2. Side view
  3. The vises I got in the deal.
All in all the head seems in good shape.
Dan.

Looks like that big vise is gonna take a little bit of WD-40.

Cutter, yep I am going to spray them down with CRC 2-26 Electrical lubricant. It will drive the moisture out of the steel and stop the rust from multiplying. It dry to a thin film to prevent further rusting.

Jenn, the vises were part of the whole deal, the total deal came out to be $2475 for the Bridgeport , the Kondia, the vises, a bunch of end mills, tool holders for the Kondia and a 7-1/2Hp 3 phase motor.
Since I got the Kondia for $500 (estimated scrap value) The M-head was $1500 the kurt style vise $200, the Bridgeport vise $100, the tool holders and end mills $100, and the motor $75. I think I got a good deal, that will be even better once the Kondia is up and running.

Wow, I think that was a great deal. Do you have any idea when you are going to get into the Kondia? Not to rush you mind you. Just wanting to see more pictures.


How do you think the Kondia vs Bridgeport compare?

Jenn, if it would stop raining I would have started on the tent for the inventory that is in my work bay, but I cannot see mucking around to move stuff, right now. I was out in the weather today at work and will be tomorrow, the weather forecast is for rain for basically the next week here.
Thursday is supposed to be nice, if it is I will start getting the area the tent will set in cleaned up.
The M-head is a 1/2Hp and the Kondia is a 3hp head, so the Kondia wins the horsepower competition. For ease of use I think the Bridgeport has the upper hand there. I think they will both end up having specific rolls in my shop, the heavy duty milling and drilling will end up on the Kondia and the finesse stuff will end up on the table of the Bridgeport.
I plan to equip both with DRO's over time or when the money shows up to do it with.
Dan.

It's spring time and the flowers are blooming. And ah, yes the rain.

I;ve been pretty much out straight except when it rains. So I guess it's good that in rains now and then. We were supposed to have rain the last 2 days but it missed us.

Looking forwards to more pictures.

The Kondia looks like a biggin. I wasn't able to find much info but wasn't looking to hard. Did you know what it was before hand or just after the fact kind of deal?

Jenn, the Kondia was represented to me as a CNC without the control box. I was not interested in it at the time as a mill for in my shop until the seller said he would take scrap price for it and we settled on $500. We later discovered the control panel was there, but out in the weeds. The control panel has a magnetic tape (cassette) to input data, that is as far as I have investigated it. It could have a small computer inside of it but If I were to make it into a CNC again I would buy a kit for it instead of trying to repair the panel.
CNC holds no draw for me in a mill, a plasma table, yes, mill, no. Most all I will do in the shop are one off projects for my own use, so a CNC mill would not be very practical for me.
So the short answer to your question is yes I did know.
Last night the rain let up enough for me to measure the table on the Bridgeport. The table specifications are as follows.
  • Table 9" X 42"
  • X axis has 0.081" backlash right now. (table L-R)
  • Y Axis has 0.020" backlash right now. (table in and out towards or away from column)
  • Travel X -Axis 24"
  • Travel Y-Axis 9"
I probably knew which was which in school but have forgotten so I am guessing when it comes to the axis' the only one I am for sure is Z the quill.
Got some of the area for the tent cleaned up tonight but I need a inner tube for my hand truck to finish the job. I will pick one up Friday evening at TSC on my way home.

Dan,

Is your motor 3 phase, I have a motor off of the original Franken-Mill head, that came off a M-head, 208/230 3 phase, with the special mounting flange, you can have it if you want it, I was going to throw it away, but never got around to it. Let me know, if you want it I make a trip to NW Pa, Digger Doug's sander looks tempting, don't need it, but looks tempting.
