    3phase motor on southbend 10L

    Get the VFD and wire it directly to the motor. Remove the motor starter. It is completely unnecessary and could actually cause damage to the VFD if it should drop out while the VFD is under load. Do not use the VFD's control panel as it is not a durable device. Make up a a local control...

    Best method for turning Delrin

    Delrin responds very well to sharp HSS bits with a bit of back rake. It does almost as well with carbide inserts that have chip-breaker grooves close to the edge so as to effectively form some back rake. Those are the ideal forms, but even simple flat topped inserts with zero back rake work...

    Need help with a Winchester model 70 extractor issue

    I never understood why Win decided to use that little pointed plunger under the extractor. Unless the plunger hole is clean and lubed, and the plunger smooth and burr free, it is going to impede the plunger's movement. Savage uses an identical extractor except that it uses a 1/8" ball...

    5-C collet chuck

    IF your lathe has a large enough spindle taper(M5) then a better solution is to get a soft M3 to M5 sleeve and machine the bore for a 5C collet in situ. You will need a simple tubular drawbar with hand wheel, but that's not too hard to make. The advantage is minimum work piece overhang and...

    Thanks, Boyd. I had suspected that the heavier trigger pull was the reason, but it's good to hear it from an expert. RWO

    Need help removing the barrel on a Ruger No.3

    It should not be that difficult. The last one I removed came loose by hitting the bottom of the action flat a couple of times with a plastic faced hammer. Did you remove the extractor first? RWO

    Cold blue for a barrel

    Brownells Oxpho-Blue liquid can give a damn good finish if you remember that cold bluing is an autocatalyic plating process. It requires chemically clean steel. This means a fresh polish and a wetting agent helps a great deal. If you can manage it, wipe down the freshly polished and...

    Question to machinists about dial calipers.
