What is the size of the thread on the R Sorby toolrest stem?
I haven't got tap or die that size.

Do you have more of the system I went to Robert Sorby have a page of the Modular tool system I must say it worries me greatly screwing a tool rest on a post is a beaut idea how to lock it in position so when used on an awkward position the rest wont swivel and cause a dangerous condition with all your gear its a piece of cake to weld a secure tool rest for special purposes.. I don,t use a single round rest I settled on a 45 degrees flat rest some years ago happily it seems to be so restful to have more of the chisel supported this way what do you think Mark?.
I notice Woody in his video today uses a round rest similar to the Sorby one perhaps Woody would comment on his choices.

Mark the thread is 12mm x 1.25 pitch. I have just purchased a set of taps of that size from China so that I could make a special toolrest !!!
Perhaps he's already got a Sorby stem and wants to make a new rest?
M14 x 2 Grump, you must haves arms like popeye! I struggle with M12 at times!
I made a couple of rest that thread onto a 1" stem, not sure of the thread, M10 or M12 and they haven't moved. I used silver steel for the rest as it's quite tough and nice and smooth.

If you don't got a tap or die the right size, change the thread to one you do have, simples init?
Specially if live in the back of beyond like Mark does and with a lame finger and snakes in the shed.
Popeye is a whimp init?
Agreed, unless he wants to make it interchangeable with the Sorby rests he can please himself. I think M10 or M12 should be about right or indeed 3/8" or 7/16" if he has the tools. The silver steel I used for the rest is I think only 3/4" diameter so I didn't want to go too big in case it made it too weak. Sadly there's no way I can put an S bend in a short length of 3/4" bar like Sorby do so if I want one of those I'll have to buy it!

Put an S bend in a long length and cut the ends off.

I have used this system for years, never had a problem, Just screw the cross bar on and give it a bit of a bang with your hand ( not my L/hand ATM) and Bobs your uncle.
This is the reason why.
Wonder what the Aussie equivalent is?
