Yesterday I won a Lushington LBK161... wagered over 18holes on the golf course against me paying for dinner(did anyway).

The friend I play against owns/runs a local engineering shop and occasionally gives me little shiny trinkets to play with. Anyway..the way he played I can only assume he was desperate to unload it :).

So what do you think it is?...

As you can see..its fairly substantial for its purpose. 4ins main diameter with a 1ins bore. It came off an old MEC auto

plugboard lathe they got rid of a few yrs ago.


I'll need to make a holder to use it..maybe a morse taper fitting for the tailstock or a holder for the toolpost.
Its easy to setup..once you adjust it for the diameter ,the lever makes it clamps on like a pair of mole grips.

If you haven't guessed yet...click here to view the guts of the working end.

Is it a threading head that holds individual dies ?

Is that a clamp knurler?

Yep .. Its a knurling head.

According to Steve who gave me it... It uses 3 matched Horia knurling wheels to give good quality knurls. The wheels are changed to give rougher or smoother knurls.
The machine it came from had some sort of floating holder which took all the stresses out of the knurling process.

Its a simple idea... I think it would be possible to imitate it by using a 3 jaw chuck with the knurling wheels mounted on soft jaws.
