    Default 3D printed parts for me 1942 10ee

    hehe, probably seems a little blasphemous, but it worked well. Part of my effort to get my '42 round dial going. A VFD was installed driving a 5 hp motor mated with the 2sp back gear (The lathe was acquired with only the back gear box, cut off from the original motor). I wanted to use the machine's original controls so came up with this as way to mount a potentiometer and drive with the chain from the speed control knob. There's an adjustable brake in it (with a brass bushing) so I can create some friction so it has the right feel and doesn't move after setting. More photos on my web site.....that is also a work in progress 3D plastic parts for the 10ee - Metallum

    Screw blasphemy. You use whatever tools are available to you to make it the way you want it.

    I think it's a great use of 3D printing, a good design, and good execution.

    nice work.

    Much nicer than the hack job I did with OEM parts... Don

    That's all really impressive work!

    Thanks for sharing the 3-D application to solve a "legacy" challenge, not just cleansheet, new product, or bleeding edge.

    Kudos aside...

    Why not simply couple a bog-standard sub $15 Bournes or similar 5-turn potentiometer directly to the control shaft?

    An ignorant "O" ring or an adjustable faucet-stem "packing gland" robbed off the plumbing supplies blister-pak wall is all you would need for friction to prevent it creeping under running vibration.

    3D could be used a lot more in aplications like that. It looks great.

    The other part of the speed control back gear shifter is on ebay. The whole shaft from knob and handle to the shaft supports and the sprocket at $129.00. 0 bids 5 days left
    If anyone needs one.
