    I used to go to Gainesville, FL for the Gatornationals during the seventy's, so I was there to see Russell Mendez' Free Spirit run on Saturday. I was in the pit area for his last run (Sunday, 1975)....

    4 1/2 gallons of one, half a firkin of the other. Or is it 5.4 gallons of one, half a firkin of the other?

    Rob, Thank you.

    I have sent an email to Gene about the 25 KW unit. That looks like that should do what we need and work with our 3 phase power supply. I'll know more after I hear back.

    Thanks...
  7. How do I find the right induction heating coil and power source?

    We are interested in knowing if induction heating would improve our process over O/A and rosebuds. And, if so, how do we find the right equipment?

    This is for a recurring job that has a shrink...

    Hey, Zahnrad.

    I'm not at work to test this.

    #599 is the system variable that sets the first number when using P1 in G47.
    This trick resets it each time to what you want by having each G47 be...

    Are you saying that the Index gearing has to be exact or that it can have an error and that it is acceptable if it is in (a) tolerance?

    Yea, if I had to do it like the OP I would have the hob made...

    About the C constant:

    Barber-Colman refers to the C const that is produced from:

    as the theoretical value of C.

    You can round it off to a...

    I calculated the 21 1/3 from this example:

    You are, I'm sure, referring to the 81.1, 38 diametrical pitch one. I'll sync back up.

    You aren't doing anything wrong. I think you are missing a couple of important steps.

    Most people who do this simplify the C constant to a whole number, then look for an exact match. If the first...

    I looked at your spread sheet and I see that the circular pitch is off by a small amount, but what is off more is the C constant. You have 41.84049744. The actual C constant for 53 * 90 / 26 * 91 is...

    Yes, that is extremely important to do.
    Using the desired feed rate, you calculate the C constant that determines how much the part is rotated out of sync. The intentional rotating of the part "out...

    You can't arbitrarily change the feed rate. It is tied in with the index.

    This is what I have come up with for your change gears as best I understand your situation.

    It is, indeed!

    I have a question: What code did you use to embed the *VIMEO* video? I'm not having any luck with that.
