    Watching your video Chris, I think you can hear the "snap" of a magnetic contactor closing when the machine is turned on. Or is that the sound of the push button switch?

    Dimensions on the drawing are only to 2 places, hundreths of an inch. Seems a hole saw could hit that tolerance

    How does the holding force of a mag chuck compare to a vacuum chuck? Theoretical max for vac is 14.5 psi, usually less in practice.

    If Grainger has it, buy it from Zoro. Same outfit, WAY better prices and free shipping for orders over $50

    Can't imagine how anyone can be surprised that the states finally figured out how to extract sales tax on internet purchases. It must have driven them crazy seeing all that low hanging ripe fruit...

    This is getting interesting, the slotted end is clearly up for these. If I were going to drive a lot of them I'd make a tool with the blade for the slot and bored thru for a screw also, get the best...

    How is watching youtube videos better than asking for help from a bunch of experienced machinists?

    Ideally he'd find a local machinist who'd help him out - how likely is that to happen?

    Scruffy, didn't you say you were cutting mostly HDPE? So do you need the rigidity and accuracy of a mill, or would a high quality router be sufficient?

    There's no doubt in my mind that a small,...

    Yes, but he has gotten a bunch of sympathetic and helpful replies, including from one of our most avid ass-reamers.

    This is the sort of thing that inspired this post. Just stuff it into a subforum and let those who care to help (or excoriate) him. The rest of us would never have to see it.

    Does the slot intersect the external threads? Seems like that's the only way it could cut them. I'm not at the shop so I can't examine mine.

    Yes Chris, the slot is an "attractive nuisance". And as rons noted, there is a lot of contradictory info out there, even on manufacturer sites.

    Damn, I've been putting mine in upside down all these years! I figured out a long time ago to drive them with a bolt and stop nuts, but never realized the slot was there to cut threads.

    Chris,...

    I'm not trying to change anything to suit me, I'm perfectly happy here. I just thought too much time and energy is wasted here complaining about and insulting hobbyists. Seemed worth thinking about

    For curved surfaces you could use a follower bearing attached to the router base, as in laminate trimmers.

    I've cut aluminum and brass on a heavy woodworking shaper w/ lock edge hss knives. Kinda...

    After reading the latest "hobby" post, it occurred to me that we will always be getting these, no matter what the guidelines say. While many members clearly make their objections known, there are...

    Great thread, stuff! Wish I'd heard this stuff before I tried broaching, pretty frustrating when you can't keep it straight. Thought it was just me...

    I can see it in educational use, for all the reasons mentioned above. And schools aren't always all that budget sensitive.

    But for the hobby and garage market, seems far less likely. It looks...
