Hi All, Recieved my new to me Bridgeport today, very happy with S&R Machines in Connecticut for a fine job on all the upgrades. They shipped it with the head turned down 90 degrees which makes sense. Just wanted to do a sanity check on the procedure for rotating it back up. I see the four bolts that need to be loosened and they warn that when the head is up, be careful to prevent it from free falling down. Do I use the tilt adjustment screw to crank it back up the full 180 degrees or can I use the hoist to lift it up? Thanks, Mike in Michigan

Is there anyone using a servo motor as a powerfeed motor? I came across this online and thought it would be quite innovative and the system could be used on multiple types of machines Milling Machine Servo Motor Auto-Feed Power Feed Does anyone know of a controller for a servo motor to enable it to be used as a power feed motor? Thanks

Hi All, Can anyone help? I am the proud new owner of a J head Textron era, British built Bridgeport Series 1 and I am doing a bit of refurb on the head. It's a 1985 machine, does anyone know the correct colour I should be using? I did buy a can of the Adcock & Shipley cement gray and to be honest i really don't like it and would prefer a more traditional machine gray. The machine was repainted at some point, I think by a toddler with a toilet brush, and so I don't have anything to guess from, the layers underneath are not really obvious or helpful. If there is not consensus I'll paint it a Colchester gray to match my Master but the correct one would be nice. Many thanks in advance, James

I am in the process of buying a used 2J2 mill with a 2 hp motor. I am presently waiting for a snapshot of the motor nameplate from the dealer but I am getting curious/nervous while I wait. An electrician told me today that he has run into machinery motors that are only wound for 460 V 3 Ph and I planned on running it with 230v 1 Ph and a VFD. Can anyone tell me if the Bridgeports are typically capable of being connected to 230 or 460 3 Ph as I have seen on most industrial motors. Thanks, Mike

Hi All, I had the fortunate opportunity to be able to use the company machine shop equipment before retiring but now I really miss it. I just purchased a used Bridgeport mill from a company that buys and sells equipment in Connecticut and am not completely sure which model I have coming. Can you help me identify it and maybe comment on its visible condition. I think it is a 2J based on the Vari-Speed I can see. I can't tell if the tag on front says “Series 1” or “Series 2”. I am told it is 2 hp. It includes a new VFD, a new DRO, R8 collets, vise, hold downs, power feed and misc cutters. Paid $4500 plus $500 to ship to Michigan.

This shouldn't be so hard to figure out. Pulled everything apart only replaced the 2 bearings, replaced with the exact same gears. When I install the shaft assembly and tighten up part #88 (dial holder) it snugs up the bearing to the shoulder in the elevating shaft and pulls the whole assembly out away from the elevating screw gear. Before I start screwing around with spacers I'm hoping for some insight from the experts. I measured how far out it is from being engaged with a bit of backlash and it's about .250. I had a new set of gears so I replaced them but no difference.

When you need to transfer wire from that 20kg spool you got a great deal on over to something that actually fits in your welder...

In a marketplace advertisement I saw a Bridgeport with tree heads, i have never seen such a version, anyone of you?

I have a M head on my Hardinge TM mill. I would like to put a quill DRO on the M Head and use the fine feed hand wheel. If you have done this, could you please share your design (pictures, etc.) or provide a link for a kit?

I made my own brackets to fit a scale on my J-head. My brackets move the scale off to the right. I still have access to the nuts to tram the head, to use the fine feed hand wheel and to be able to use the quick stop nut. The only way I was able to package a scale that satisfied all three requirements was to use a small form factor magnetic scale. I started off trying to sketch my needed brackets - gave up rapidly. I used very small scraps of wood, a band saw and a hot melt glue gun - took a couple of hours to develop both bracket patterns. Image attached (I hope) of the scale on my head. NOTE: I bought the 1u (micron resolution) scales - they were very finicky to get the magnetic gap so that the head would read consistently. For my lathe I used the 5u scales and they have been rock solid. I bought the Ditron / Reeson D80 DRO and scales.

Only for me to realize that I -DO- use the STOP that's there. And have a QUICK CLAMP for the one time use jobs. The DRO bolts into that area , eliminating the screw and it's threaded stops. So I have never installed it , it's a Mitutoyo unit. I don't have an immediate recollection on what the M head uses there.

I did a search for "reverse trip ball lever" and read all the messages. Non addressed my issue. I got my J head Series 1 BP about seven years ago. Outside of a few minor issues it's been working beautifully. I made a micrometer quick nut and when I went to disassemble the quill screw I found that the reverse trip ball lever was installed backward. The threaded end of the lever is not accessible. I figure I could try to drill and tap the part although it may spin around. I am not sure if it's hardened. Has anyone else had this happen? Any help is greatly appreciated.
