I have a late 70s Bridgeport 2HP mill with a Bijur lubrication system. Some of the lines are clogged with sludge and I pulled one of the thin plastic nylon tubes to clean things out. Afterwards, I was unable to re-insert the tubing into the saddle.
The existing nylon tubing on the mill measures .150 while the holes drilled in the saddle are about 0.125 (an 1/8th inch bit is a tight fit). My assumption was these lines were originally 0.125, and swelled to .150 over time, however I can't find any reference to 0.125 tubing being used on Bridgeport mills. The only size I see is 4mm or 5/32, which is somewhat larger than the existing tubing.
Has anyone encountered a Bridgeport with lubrication lines smaller than 4mm?
