I measured the shaft size and the OD of the thread and was trying to find some one who could supply a nut. They all wanted to know the pitch. Now whilst I know what they are saying (I used to use a gauge to find out this shit!) how does Joe Soap find out. So there I am, how am I going to find out the ‘pitch’ when It occurred to me that I am a member of the RCR. Why not let them sort it. So I called them.
Now Spencer came along with a battery powered Makita drill which I expected to run flat before it drilled the hole, however it did drill the hole I was really impressed.
