    I think your choices are to single point it, or my preference if loading allows, cast one from Moglice.

    Ive made 3/8 acme lead screw nuts from Delrin by using a ball end mill to make 3 grooves...

    You do it just like you have it shown. I put a 123 block under the tip vs letting it ride on the table. Zero on the left, swing to the other side and adjust until the indicator reads half the error....

    Sometimes the construction of the gearbox makes a lot of resistance, a geared head lathe can usually be put between gears and will roll over easily. If there are drive belts from the spindle down to...

    It looks like you are doing them one at a time on the 4th? I'd figure out how to get 2 parts on on the 4th you have.

    Then if you still wanted too, build two air/oil carriages with drill motors...

    I use 16ga aluminum sheet, sheared to be ~1.5” wide. I roll a piece in a U around the stock and cut it off with snips. I like to make them such that the jaws squish the u around the part so when you...

    While I completely disagree with how you are checking your accuracy, I would however suggest instead of moving from 0.000 to 1.000 and measuring the distance between the marks you instead move from...

    I would think it’s for facing both sides of a small flange.

    The compound on my Whacheon has zero marked parallel to the spindle and the graduations stop at 45. There is however a mark at ~60. That’s what I use for threading, I don’t know if it’s 60.5 or 60,...

    I’d also check what size your drills actually punch, if it cuts over you might not have anything left to ream.

    You can pick up angles or arcs with the 3D Taster, you just have to account for the offset made by the probe diameter. If you were using cad and your mill as a cmm you would pick up 3 locations on...

    I'm not sure what the big question is here. Look up the bearing on the GGB website and bore the housing to the correct size. A 2" heavy wall Garmax bearing specifies a 2.500/2.501 housing for...

    It really is like a lathe vs mill thing. T&C make crappy surface grinders, they aren’t rigid and the downfeed is often less precise. If you want to make (hard) things flat or square, get a surface...

    I'd trade the surface grinder I have in my small shop for a T&C in a heartbeat. I don't surface grind often, mostly sharpen tools. Cylindrical grinding is a pain, especially if you want to grind a...

    I use a lot of DNMG-432 (55°) or a VNMG-332/331 (35°), the 55° is a lot stronger.
