Didn't Kingshot recomend a 40tpi micrometer thread tap and die to make a single threaded one? I seem to remember it from somewhere.
It would be easier to make.

Hi Everybody----The thread in question is ME thread ( Model Engineer thread). They are a constant pitch of 40 and 32 tpi and they have Whitworth thread form. Taps and Dies are available from model engineers suppliers such as Tracy Tools Ltd.Racers":y5af1c7s said:Hi,

Hi Richard I am not sure that square thread taps are very satisfactory in a production environment. I have seen "one off" home made taps but the problem is providing clearance on the flanks of the threads so they tend to bind up in use so that is one of the reasons why acme threads were developed. Square theads are normaly screwcut on a lathe.Richard T":kznmuk22 said:Thanks for the link Arnold. I notice they do acme taps too (Will we ever find a square tap? Was it only Norris who had one?)
