Peter, I could probably mount that in the turret ;D
Ask John Prentice, I am sure he would have some suitable code.
 What kind of depths do you reckon you could take off in one pass, maybe the code I have for the pullstud in the video would suit, it is just taking light cuts due to the distance out of the spindle, I think its only taking 1mm DOC for the most part.

Hood,

I'll email John and see if he has anything appropriate. Basically I'm after something about 4" in length with a taper and a thread that is not too fine. This the stub axle.

As to depth of cuts, all I can say is that it is a 7x14. :-)

Cheers,

Peter.

Hi Hood,

1.5" diameter should be fine.

Cheers,

Peter.

Peter should also have asked what feeds and speeds you have.

Oh and as far as Bar feed, dont have one, the lathe originally had a closed centre hydraulic chuck which was no use for the work I do so I replaced it with a 250mm Dia 6 jaw manual . Always on the lookout for a 250mm- 300mm  hydraulic through hole chuck at the right price but not got one yet ;)
