Re: Bridgeport Boss 6 Stepper Motors

Hi petev,
I've use the link:
http://www.slosyn.com/ssstepmotors_stndrdnema4266.html

I got a M112-FJ-326 as a replacement that was very similar, but the
shaft is a little
shorter ( for a series II CNC )
Also keep and eye on Ebay. Search on "nema" and read the items. Big
Steppers pop up
now and then.

This is a snippet from Darrell who help me earlier:

>I have two large machines now, both with large steppers on them.

From an

(NEMA) 42 Superior

Hope this is useful,
