Hand screw cutting on a Myford.
Another tip for budding screwcutters,Rather than using either hand ground single point tools or these modern form throw away tip tools now popular is to get some old coventry thread chasers,usually they are in sets of 4 as in a Coventry die head,odd ones or sets missing some are ideal for our use.Make a holder to fit the toolpost and off you go Popular pitches needed for us would be 16,20 and 22 tpi.
