| Please note. Patriot and Supernovachucks in 33mm x 3.5 thread and 1,1/2" have to be specially made with the thread cut in the body, as there is not enough room to take an insert. The Patriot 1,1/2" version is dual threaded left and right so it can go on either end of a Harrison Graduate spindle. Please enquire if your thread is not listed, unthreaded chucks are available if you can arrange your own machining. The thread in the Patriot and Supernova where the insert fits is 38mm x 3mm. We can supply Robert Sorby Exerts to adapt chucks to fit large threads such as Viceroy 1.5 inch x 8 t.p.i. Please enquire. | |||
| Right hand Masterchucks can be converted to left hand with a conversion kit (LH body, LH nosecone, LH screw, grubscrews and key) price £26.44 | |||
| Mini-screwchucks are our own design found here - see lathe accessories | |||
| The above list is only a guide and lathe makers vary the thread they use from time to time. If in doubt ask - we are here to help! | |||
Hint on measuring your thread size
It is often possible to guess at common thread sizes with an ordinary ruler. Examples are :-
1 inch x 8 tpi. The outside diameter of the thread is a tiny bit below 1 inch. 1/8 inch divisions on the ruler will exactly line up with the peaks of the thread.
3/4 inch x 16 tpi. The outside diameter of the thread is a tiny bit below 3/4 inch. 1/16 inch divisions on the ruler will exactly line up with the peaks of the thread.
24mm x 3mm pitch. The outside diameter of the thread is a tiny bit below 24mm. Every third 1mm division on the ruler will exactly line up with the peaks of the thread.
And so on.
If you send us a rubbing of the thread we can measure the pitch. Lay a small piece of thin card on the thread and rub with a soft pencil.
