When I bought it, my MV100 mill didn't come with the tachometer that was supposed to be mounted in the head cover. This is a bit of an annoyance with the Reeve's drive setup in this machine. I happened to find a nice old Stewart-Warner tach at an estate sale a while later, but was disappointed to discover that it didn't quite fit the hole in the head, and I never really got around to turning the right bushing on the lathe. Finally, over the weekend I measured everything up, threw some CAD together in Onshape and printed a bushing:
Fit perfectly on the first try!
Printed in TPU with relatively dense infill (50%), so it's a little squishy, but not much, which is perfect for a press fit with a bit of vibration dampening. Next up is printing the correct diameter tire for the tachometer input shaft to ride on the spindle and actually read correct spindle speed.
Anybody have any other TPU shop prints?
Cheers,
Will
