Buget Warco Major 5 axis conversion

How does that work then? Are you turning the nut?

Yep, it is the internals from a flap control. Basically a screw jack with a 1605 ball screw and I think a double nut, roller bearing at the top, then two thrust rollers and a roller bearing at the bottom.
It came from a scrap metal metal chap, who deals in ex-MOD stuff ....... I think it was a fiver!
I ground off the beautiful 90deg. helical gear that was on the shaft and fitted a bored timing pulley. Shame, but I didn't want to have to sort out the end float on the drive shaft.
Fourtunaley, the screw is about 1/2" longer than the quill travel!

I am going to buy a piece of steel for the quill plate.

Hi Tweaky,

I have just read this thread with great interest.

I too am contemplating the modification of my old warco major to cnc.

I am just wondring if you could bring us up to date with developments.

I have not seen any reference as to what motor drivers you ended up using with those NEMA 34 motors from Arc Euro Trade. Please could you enlighten me!

I have the same motors in that mod and the guy assured me these drivers would suffice for the motors....

Tweaky,

May I also just ask, have you now completed this project ?
If so, do you still consider it a worthwhile project with regards to time and capital investment versus end usability, or would you advise otherwise?

Regards
