Hi all
I picked up a Yuasa spindle speeder this week, to use on my old Van Norman mill. The speeder is a 1:7 ratio, is rated for max 10,000rpm and up to a 3/8" shank tool. I think it should be a nice addition to my mill, which has a top speed of 1500rpm.
The speeder is on a MT4 mount with a tang - no drawbar. That seems a bit weird on a tool designed for milling with up to 3/8" cutters.
My mill has a 50 taper spindle. I see a couple of options:
- sell it and buy one with a straight shank
- modify the shank to accept a drawbar (not ideal, as I'd have to make a totally different drawbar to use with a 50taper to MT4 adapter)
- permanently mount the mt4 in a holder (loctite? Set screws? Spot weld?)
- ignore it and use as intended, as the small cutter forces aren't enough to worry a MT4 shank's hold
I'd appreciate any guidance!
(And before anyone mentions what a POS the Yuasa speeders are, I've read all the posts about them on PM. But it's what I could find at a reasonable price).
Thanks,
Lee
