    To understand better- after you home the X axis, your ID tool blocks should be 4.0000 from center. (at least on a machine here in the US). How far from center are you? Sounds like a grid shift...

    Thanks for the link to the Fusion post! Yup- the KMB1 is not half bad for its age. We were doing 3 axis stuff with one using Gibbs back around 1990 or so.

    Do what Gordon suggested, but add in what bosleyjr suggested: "Then hit the red hot portion with cold water." A wet rag in a bucket of water works well. Its very controllable and you can tweak the...

    I never call out a tap drill size- call out the thread (properly)_and a minimum depth for the thread. If its a thin part or on a thin wall or feature that you don't want to break thru and the needed...

    Whats with the 130 ft-lbs thing- if you are talking nut torque, in my opinion that's way excessive. I've been using Universal collet chucks since 1986, and never tightened them that tight. Might be...

    If you play with the front clearance angle on your tool, you can eliminate that overcut to a certain extent. Also adding some top clearance will help if its rubbing on the top.

    Don't mask /anodize them- as you said above, the labor to mask them can be a deal breaker. Look into just having them alodyned- it will preventcorrosion but at the same time the surface is still...

    Most manufacturers of motor starters sell the cans separately for their products. Not every motor starter gets mounted in a separate stand alone enclosure, so . . . . Good luck.

    Cheapo or not, live centers can be reground on their own bearings to run pretty true. Always good to have a cheapo one around for non-critical work and save the big $$$ one for when it really...

    That formula is for checking the setup to cut primes, by setting the machine differential to cut a specific helix angle or lead and then cancelling the lead non- differentially. If done correctly...

    Another thing to be aware of on a worn machine is that as the wheel slide wears, the head will lay over to one side and make grinding thrust surfaces parallel impossible. Just something to check out...

    This is 4340, not 4140. The torched areas might well be harder. Might be cheaper to just have them all annealed and then re heat treated after you rework them. If someone was hacking on them with...

    In a pinch- use 1018 and have it annealed dead soft if its for a magnetic application. 1010 can be tough to source, and the chemistry is not that much different from 1018.
