R2E3 and R2E4 were and still are really nice machines . I know of a few still making chips day in and day out. The look a series 2 on steroids and are capable of really heavy work.
Those servo's could be valuable if in good shape.

Im always looking for spare pallets to fit a bpc 320 / bpc 380 horizontal--appreciate if you let me know should you happen to come across any of them on the used market.
Thanks,

Jeez ... I worked for BPT untill they closed and never saw a 320. I've worked on Interacts, Boss5 ,308 ,VMC ,TQ21,TC1-3, R2E3-4, Series1-2, EZ Traks, Romi Lathes and Harig grinders. I may do some contract work for Hardinge and will keep an eye out for them.

Tom - Is there a significant difference in performance between the older round ram Bridgeport, which I have, and the newer V ram model? Would a difference only be noticed on heavy cuts? Thanks, John

Tom:
I've got a Bridgeport-copy variable speed head Taiwan machine., It has two oil cups on the front of the head and two zerk fittings on the rear sides of the head. Any idea what kind of lubricant should go in the zerk fittings and how much? I paid $80 for a few pages of a Xeroxed Chinglish manual which just says to lubricate them, and the vendor doesn't know either.
Educated guesses welcome.
Thanks,
George

What kind of grease goes in a #3 right angle head? I talked to a rebuilder once and seem to recall he mentioned an NLGI #0 grease but can't find my notes. Plus most greases in the catalogs don't seem to mention the NLGI grade so a specific product (and one that I can get in a hobbyist size single tube instead of a 50 lb bucket!) would be great.
Thanks much. Steve.

I'm not Tom, but I suspect that the dovetail design would be more rigid than the round ram.
However, another benefit is that you can shift the head farther out to take another cut beyond the limit of the Y-axis travel without losing the tram of the head, while a round ram will certainly need to be re-trammed after such a shift -- a very likely source of errors.
Enjoy, DoN.

Duh ... sounds OK to me ... Changed the name to most Bridgeport questions answered 90% of my field work was on CNC but did work on lots of series 1-2 standards BPT charged $125 an hour so I didn't get too many standards ... the ones I did were usually in the same location as the CNC's ... kinda like ..while I'm in the neighborhood.

I came to this group from alt.machines .cnc because over 90% of the posts were pissing contests between the same bunch of people. I posted the thread mostly out of satire .. I do however know quite a bit about BPT's . I'm not and don't pass myself off as a know it all but am eager to help if I can I was a field engineer for Reliance Motors and Drives before BPT and know a little about drives too.

OK-here's another question!
Why did Reliance make the field control module on the MaxPak III such a bitch to get out?

How do I know ... I just repaired them. The guys in Cleveland that made the really big money made the big fuck-ups
