    making Er16 collet chuck

    i needed an er16 collet chuck for my stepper motor.

    purchased two from ebay: "er16 collet chuck motor extension"



    i've had much luck with chinese tools, but this time... it was a terrible experience.

    the specs said if i purchased 8mm ID for motor shaft, I would receive 7.98mm shaft so i could induction heat it, then put it on the shaft



    however, i recieved 8.1mm oversized hole, so i couldn't use it... too much runout.



    took over a month for it to arrive, wasn't going to wait again.



    based on google and forums er collet chucks have 8 degree internal taper angle



    my compound was not gonna have the accuracy required,

    so i used a bevel protractor to get the precision within 0.1 degrees, which for ER collets is enough



    even greater precision could be set, if i purchased electronic bevel protractor, but it would cost me over $600 for quality one.

    i just went with vernier one, which wasn't too bad.



    below is the link to the making vid of this collet holder



    feel free to comment

    Nice video but you breezed by bore diameter measurements.

    Curiosity is killing me here though, why an ER collet on a stepper motor? I’m thinking this will need a video all on its own.

    Most enjoyable, watched right after eating breakfast. Nothing better for starting ones day than watching a bit of machining. Far better than the news or morning shows.

    Nice work and enjoyable video, for setting exact tapers and I mean exact with only a DTI have a look at Joe Pieczynski's channel here

    it may help with future projects. I agree with your comments on chinese quality I purchased a cheap set of ER 20 collets and had to grind the bores of two of them to accept the nominal sizes. I would do it again but you do get what you pay for, at least you did not have to make the closing nut.
