Hey guys, here is another quick "how I did it" for the real weaver knob swap.
the Tomen weaver is a M4 thread, my real knob is fitting a tap hole I did with a 10/32 tap. so, you have to rethread the tomen hole.
for that, I drilled the hole with a 3.5mm bit. I think a 3.8 would be better but I didn't have it on hand. the 3.5 didn't remove all the threading and was a little bit small for the new tap bit.
then, tap the hole with the 10/32 bit. The hole is really close to the side of the plate, in my case the new threading is visible from the outside. I don't think it can really be avoided as if you drill too much to the inside of the piece, the knob will not fit its recess anymore.
here is the result after the threading
as I'm a real OCD person, I filed a tiny bit the bottom of the knob recess until the knob was threading exactly as the world con version. It really wasn't much, the threading is really fine so just a bit of filling and the knob does a half more turn
and here is the final result. really happy how it turned out.
I hope this can help.
As you can see, I'm really enjoying my kit build and are doing it really slowly, working on it from time to time (I got it last summer). I really enjoy working on it, so I just don't want to rush it.
cheers guys
