Thanks for the info Wendel.
I had a rummage around and managed to find a M12x1.75 split die and tap.
Put it into the die stock as Wendel described and it worked first time, no problems at all.
I never knew "un-split" dies where for re-cutting damaged threads and split dies are for cutting new threads, so I've learnt something along the way which is good.
Makes me wounder why these cheap tap and die sets always come with un-split dies.
I used the pillar drill to make sure the tap went in straight which thankfully worked out well.
Really happy with the fit of the thread. I was worried it was going to be too sloppy as I took the shaft down to 11.7mm but thankfully it is fine and I like the courser pitch too.
thanks for all the help guys.
On a side note, how difficult would it be to machine this?
I was thinking of taking a bit of 12mm stock and machining one end down to 8mm then flip it around and put the 8mm end into the 3 jaw chuck with a 2mm spacer to machine the offset 8mm part.
Would this work? it doesn't need to be dead accurate just in the ball park.
Sorry for rubbish drawing
