Another homemade milling machine

Hi Shipto,
Have you thought about using a VFD and 3phase motor rather than going to all the trouble making a gearbox and then only having three speeds ?
Another option would be variable pulleys ala Daf variomatic ? also used on most modern mopeds
you would need to be able to control the movement of the pulleys rather than the centrifugal(?) mechanism used on them
I have seen old motorcycle gearboxes used to provide usually four gears on "Mad Mod" machines :scratch:

A vfd would be nice but probably too expensive for me at the moment and to be honest I hadnt even considered the variomatic option I may look at that :coffee:
However it wouldnt be just 3 speeds as my plan is to have a 4 or 5 speed stepped pulley running a quill which would then go to the 3 speed gearbox allowing up to 15 speeds. It will most likely have to have a temporary head setup to start as whatever I decide to do will be too difficult to do with the lathe and thus it will have to make its own final head setup.
I did think for a short while about using a 150w dc motor I have which came off a micro lathe but I think power would be a issue with that.

I'll happily send you a brand new (ABB Part # ACS55-01E-02A2-2) 0.37KW / 1/2HP rated VFD if you got a motor to suit or even if you can get a motor easily :beer: (I've got 1 or 2 from an old job)
I believe that anyone who is mad enough to build there own mill :loco: deserves a little help :thumbup:
