    At a previous shop we never made guides out of Ampco 45 but we made a lot of guides out of Ampco 18. From what I know about Ampco materials, 45 is favored where the bushing may run out of lube and...

    Isn't 1 micron equal to 40 microinches? That is hardly a difficult requirement.

    Now if the OP actually means single digit microinches, that is only slightly more difficult.

    That is a big rigger in Wichita. If you need something done now, you will have to get them to do it. Mostly because Belger Cartage is usually booked up months out.

    For a TG100 I would use a moderate force to loosen the nut, say 150 lb*ft or so. If that doesn't loosen the nut, try a hammer and punch on the back on the tool while the nut is tensioned for removal.

    I have two QC 30 Mills. I have made some holders from scratch, modified others with a bit of weld on the flange, and bought some from eBay. I have modified holder flanges on my lathe successfully....

    HSS can be silver brazed with little loss of hardness. But for harder cutting tools after brazing I use cast cobalt based tools such as Stellite "j".

    If you could forge the appropriate shape from an alloy steel I don't know if heat treating would benefit. You could silver braze HSS to make the cutting edge. I have used parting blades when I...

    Vertical axis machines are easy to sweep. Sweep with an indicator with a horizontal axis and you usually get junk results. The sag of the indicator will be significant. If you doubt this, set up...

    It sounds like you are assuming the error in flatness will be of uniform geometry. That is far...

    To cut down the new gib you don't need a one-piece gib in your machine. Insert the two pieces of the old gib and adjust as necessary. Now you can machine your new gib down to proper thickness.

    My vote is also surface decarb. If you need it to size you are hosed. If you can stand to polish off the decarb material you will find it hard underneath.

    About a 3/8 diameter ball bearing and a 20oz hammer. Will put a nice chamfer on the corner and displace the material down the hole quite a ways. Do each side and then resize the hole.
