I wouldnt think of that as a good buy. Unless you know for sure the condition of the non cnc part.You might dump some cash in the head before you even start the retro.have you heard it run and ran it through the speeds. Those are not a machine people look for.Look up some  auction achives in your area to see what theve been selling for. Al

All good food for thought......and I'm hungry.
I cannot find adequate steppers for a BPort axis.
Nothing big enough.
Any links ?
Thanks much,

RC on my series 1 Bridgeport I have 916 oz in steppers, the gearing is 2.5:1 if I remember correctly, you should be able to find steppers easily in that range. I think the original steppers on the BOSS machines were about 900 oz in and the early BOSS machines ran 1:1 gearing so that should be plenty torque. Servos are the way to go if you want speed and acceleration and you can get stuff from eBay at a decent price if you know what you are looking for, also might be waiting for Brett to get back about the drives he is trying out.
 Here in the UK that series 2 with the 151 control would go for probably $3-4000 and even the old BOSS series 1 in your last pic would be $2000 or there abouts. I got mine for $800 but that was 3 years ago and the price has started to jump up, probably due to the fact that Mach is known about now by a lot more people.

I did find some biggies at Keling and Anaheim.
I might get the II for 2500.
Also looking at a regular J head BPort with a CNC package on it.
And I have an older step pulley BP here that I just might motorize.
Thanks for your help,

Guy's I m working on a Bridgeport R2E4 boss 9 servo machine and I plan to use the larken Viper drives. http://www.larkencnc.com/viper/v200.htm   they also have a support site on the CNC-ZONE   My servo's are DC Brush and 14 amps continious and 165 volts they say they are un conditionally guaranteed so I am going to give them a shot...
