    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...

    In my opinion, the stupid software is the crap that doesn't actually rotate the image but just writes some garbage in the file. If you use something like Graphics Magick to manipulate your photos, it...

    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...

    No one who is any good will help. This is their livelihood.

    How old is that guy ? Or do they just use that name for whoever answers the phone ? I swear they were hauling machines in 1975 and Joey was the talk-to guy. I used them a few times, they were okay.

    It was slang in the mid-1800's. The few definitions you will find are all over the map. I stole it from a play, it seemed appropriate. Common definition is not what termite came up with.

    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....

    ^ Nah, I think it applies okay here. Like your idol, the Great Orange Babboon, when faced with anything outside your limited experience or understandig, all you can do is lash out blindly. And the...

    A lot of the cost is in the geared-head headstock ... if they did something like a three-speed with a variable speed motor, and drove the leadscrew electronically, should be able to cut the cost...

    See ? If you'd been getting your exercise shoving the tailstock back and forth you'da been in good shape for date night ! :D

    With anything under 14 teeth there's going to be undercut. Measure the bore and report back.

    Jeeze, you guys. Just squirt a little juice on the ways and give 'er a shove. They don't weight that much, these don't swing 40" !

    They also chatter like a mofo unless you have a lot of mass and hp and push them, and they won't go into corners.

    For this person, I'll stick with recommending triangles ...

    Usually that's a symptom of unevenly ground lips ... and I'm not sure what you are talking about with "thin webs" ? Split points sure but as far as I know, webs are webs, unless you mean the...

    There, that cuts it down a little :D

    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.

    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,...

    You frequently can't get the exact lead on a hobber, either :)


    Yup. I thought he might want to make useful stuff, but then he started talking 4" chucks ... In that case, a little mikron or...

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