Hi Guys,
I managed to strip the thread in my cheap Chinese die stock recently, so I decided to make a new one.
I did a drawing to give me something to follow with my new DRO on the mill. I've placed a copy here.

The bits in blue are just in case somebody would like to make one with the corners milled off. The 7 mm holes are for threading M8 for handles to screw into. My existing handles are threaded M8.
