    Another approach would be to quiet down the 5hp recip. Most of the noise is generated at the air INLET, so install a 'muffler' on the intake. I bought one from a Quincey dealer (Brehob Electric,...

    I learned the hard way on a T-Plus NEVER to change anything before re-threading (i.e. for size). This control was just prior to the fusion 640t control. So I am amazed you had no problems adjusting...

    Your machine does have a "MANUAL" machining unit. Works pretty much like EIA for moves and speed/feed. A little experimenting and you should be good to go.

    The radius has nothing to do with flatness. The spec means just what it says, nothing about radii. The best you can do is measure over a 4' length and expect </= 0.008" total deviation.

    Try honing I.D. first, then grind O.D., on freshly ground arbor if you can.
    I have ground O.D.'s with al-oxide wheels. Since you are only removing a tenth or two per side you should have no trouble.

    If someone else has this problem, it can be machined with the "Spiral" machining option. Have to write a manual program to use it as it is an EIA option, but it does work just fine.

    360 degrees divided by number of teeth yields degrees per tooth. Divide this by two to get degrees per 1/2 tooth. This is the angle to rotate one keyway relative to the other.
