    Re: JR's SX3 build

    my only criticism is that I think you need some kind of spring between the two ball nuts. the screw is not perfect and the spring will also for some play and preload, vs the static bolt you put in. ...

    is there a reason you didn't use commercially available pull studs? also would you be willing to share your prints of the mods since your going to the petal clamp?
  22. Re: PM45m(rf45 clone) cnc build log with factory 3hp variable speed

    have you thought about using a hardened sleeve to protect the spindle?
