Can anyone tell me if there is an easy fix to the following

I have just drilled and tapped M6 holes with a M6 x 0.75 pitch tap.

I bought M6 studding which will not screw into the new tapped holes. I’m guessing the studding in M6 with 1.00 pitch ?

Is there an easy fix ?. Could I re tap the existing holes with a M6 1.00 pitch tap ( which I will need to buy)

Thanks gents I think I should have asked “what is the minimum wall thickness left after the thread has been cut “ that time s adequate for its use.

Hi all help please. I need to make a number of female to female thread connectors. Having drilled the appropriate hole size and then tapped the same, what is the minimum amount of material that should be left from the internal thread to the outside of the brass stock. Is there a rule of thumb for this. . The connections will be used on my small boiler expected to steam between 30 and 40 PSI

Thanks everyone for your advice and help. I have adapted my woodturning lathe to turn some boiler bushes for a small pot boiler I intend to make. Research has come from Tubal Cain and Stan Bray books. I had a small plate in my drawer and put it on the tool post frame. I then bought a small cross slide with tool post and attached this to the plate. I have managed to turn two small phozphor bronze bushes for the boiler shell. It’s slow work but with fine cuts I am pleased with the results. I am now wondering how far I can go with this system. See photos.

Hello all. I’m just starting out with a couple of small projects and I am using tubal Cain publications to make some small pot boilers and stationary engines to get a feel for the hobby. I do not have a metal lathe or a milling machine. If I were to buy a stationary engine kit with the raw castings is it possible to make the kit using hand tools alone.
