    If you post a photo of the ways in the "Machine Reconditioning, Scraping and Inspection" and ask about B&S MicroMasters, I am sure that someone there can tell you.

    You've checked the geometry...

    Good that you are cleaning out/fixing the lubrication system.

    To my eyes the ways don't look good. This is what good ways look like:

    You might be right about this -- I am not sure. I think it has to do with the rate at which oil is being fed to the long ways.

    I don't see any oil pockets or flaking on the bottom ways. Are there oil pockets scraped on the table side? If not, it seems ripe for stick-slip problems.

    Hi Richard,

    I have a question about something you wrote above:



    I understand that the design is meant to constrain the different degrees of freedom to ensure that the spindle rotates about a...

    I'm confused. You come straight in with a wheel and grind off most of the diameter on the last 1/4" of a 3/32" drillbit. The small diameter part is a pilot. But remaining 3/32" drill won't drill,...

    I just came across this thread again, and realised that I left it dangling, so am closing it out now.

    In the end I fitted a 200mm handwheel to the Z axis of my second-generation 1964 FP2. Factory...

    I was struck by "10 gallons per minute". That is about 40 liters/minute or close to 1 liter/second. How do you avoid a flood? Is the machine completely enclosed?

    Hi Ross,



    Yup, quiet is what I am after, and I'm afraid that a plastic-pad tensioner like you describe will make more noise, not less. But the cog belt idea has merit. Would that have to be...

    The best way to say "thank you" is to post a couple of photos of the finished gears with the bearings in place.

    They just phoned me. Very nice people, but unfortunately the largest tensioner they have in size 06B is 36 teeth, and that's apparently too small to fit here.

    Karl says that the chain type is 06B (= 3/8" x 7/32"). I'm checking about the Roll-Ring tensioner.

    Yup, standing on your head is needed for the bottom row. Also helps if your eyes are at the top of the head, not in the normal position.

    Unfortunately the wireway below the long row of K-M...

    I only have experience with a single machine, my 1964 FP2.

    The motor drives a pair of identical V-belts. These run on a larger upper pulley, that drives the input shaft for the upper (spindle...

    Replying to the comments:

    JST: you can remove these from the DIN rail by pulling directly down on a white plastic clip which retracts the retaining finger from the rail. BUT that white plastic...

    Klöckner-Moeller motor protectors

    Slightly off topic, but I need to vent and this seems like the best place.

    My 1986 J&S 540 surface grinder has a small 3-phase coolant pump. The impeller section has pretty much rotted to bits,...

    I am going to reassemble with the taper thrust pulley on the motor shaft and see if that and the new rear bearing make everything quieter.

    I checked the specs. It was hard to find run-out specs...
