Hi
I have a denbigh no2 flypress and would like to make some tooling.
The tool insert end is a threaded hole not a plain bore and lock screw.
Does anyone know the thread id?
3/4 9tpi as close as I can see..
Thank you
The picture is showing 4 threads over a tiny bit less than 1/2" (0.493"), so that should be 8tpi. Measure over the full 6 threads available and see if you get very close to 0.750" on the caliper. If it is 3/4"-8, that is non-standard.
If it is an unusual thread, rather than make a whole heap more of them, maybe someone can take the one you have, drill out the middle of it and tap it M8 so you can use standard bolts to retain the tooling.
