    Lappy is Mackletosh 10.7.5

    Can't go any higher without jumping through hoops. Have parallels running xp on it but didn't try that.

    Yeah, I walk the walk :D

    Downloaded it, didn't work. Once upon a time places would list the basic requirements for software, so you could avoid wasting your time getting it if you knew it wasn't going to work.

    I hate...

    Nice choice :)

    Could be worse, hunh ? Graphics makes it easy to visualize how bad the situation will be. Are you using commercial software or is this your own code ?

    Also, what kind of fish are...

    Like I said, up to GregSY. He can do a shit job like you suggest and have it break or he can do it right, for cheap and just as fast, and have it work for the life of the machine. His choice.

    Picky mean-spirited comment :) That's actually hobbing. In a Sunderland (or Maag, who invented it a hundred years earlier) the rack stays stationary while the blank rotates across it.

    If you want...

    Thanks very much, David_M. Not too pointy. Looks good.


    No chance my ass, undercut teeth are quite happy to break and that head weighs more than 6 ounces. David M very kindly did the hard part,...

    Except when he tries to run the rack past the pinion, it is exactly as the drawing shows ... the non-undercut material will not allow the rack to pass through.

    In other words, it will jam up...

    That'd work but I'm afraid his arm would fall off about halfway through :D

    Possibly our computer-talented guy who likes the math of gears could develop a dxf file for the shape ? Then laser a...

    I was hoping that was what he meant but here on the internet, better safe than sorry :)


    In fact that's often done on demanding applications ... it's pretty common when you have a small number...

    With generated teeth, when you get below 14 teeth with a 20* pressure angle, or 17 teeth with a 14 1/2* pressure angle, the cutting action itself takes a slice out of the bottom half of the teeth....

    With anything under 14 teeth there's going to be undercut. Measure the bore and report back.
  12. This is my own personal opinion, don't want to...

    This is my own personal opinion, don't want to argue about it, but the metric system of teeth, aka "module" sucks balls. It's upside-down and backwards and inside out and stupid. It is much more...

    If you stick to inches, then translate at the end, it'll be easier. Module doesn't make sense.
  14. Metric doesn't work the same as inch. It's upside...

    Metric doesn't work the same as inch. It's upside down and backwards, so you really should either do it entirely in metric or in inch then translate, but don't try both. Module teeth don't do pitch,...

    If you could get a little info on the pinion that would be good ...

    Frequently, on small pinions like this, they will cut one fewer teeth than you'd calculate from the specs. Gears with small...
