How about turning the concentric areas in a 3 jaw, and then hold the long spindle in a four jaw to offset the right hand end for the thread cutting etc?

Make a bush, but drill or bore it in the milling machine to the required angle. You could either set the mill head over to the angle or rig some sort of sine table arrangement.

Then machine one end of the part, hold in the wonky bush (grubscrew perhaps) with the bush held in 4 jaw chuck to machine the second end.

You still have the problem of getting the intersection of the two wonky axes in the right axial position. A bit more examination of the part needed to determine where and how important it is and how the OEM did it.

Martin types faster…

On a lathe, ER collet block bolted to an angle plate bolted to the faceplate.

Make it out of two pieces silver soldered together, the joint on the RH end of the 35mm dia. part. It is easier to set up in the mill to bore an angled hole the receive the threaded part

Between centres.

You need two centres in each end, in waste material, that'll keep the two ends in the correct position.

The offsets can be calculated or use a drawing, they'll be different for each end depending on where you want the intersection of the two halves to be.

One pair does the first bit the other pair do the other.

Funnily enough I once bought a 4-jaw chuck from a man on Ebay which would probably have made a breeze of this job. The swine.

..Anyway, just out of interest, what's the make of the grinder? – it seems like a bit of a complicated manufacturing solution to a simple problem.

Ah, now you say it, it makes sense – I was just interested because it's rare to see a production part these days where other factors have influenced the design over just plain 'cheapness'..

Perhaps not that elegant? The ProEdge requires the use of two Tommy bars to adjust the tracking whilst Axminsters Ultimate Edge just uses a single knob.
