Re: IZH 46M Cylinder flaking cylinder lining?

I took it all apart - whoa that cylinder was tight! Took several upgrades in technique to get the pin and cylinder out. I ended up using an allen key bit from my tool kit - the kind that goes into a driver handle, or screw gun - as a punch, to give a nice surface to hit and a short, stiff column for...

IZH 46M Cylinder flaking cylinder lining?

I recently acquired a 46M, and despite being advertised as 'working great', it's not. Oh well. I'd rather fix it than return it. It leaks down, and I pulled the air cylinder assembly apart and found lots of flakes and crud on the plunger and down inside the cylinder. There is a coating on the inside...

Re: TAU 7 valve & spring issues / trouble-shooting help

Success! Made a little aluminum spacer, it does the trick! It's a snug fit in the spring, a slip fit on the valve. Lathe for the win. Shot off a bulbs worth - cranked up the power by a couple of turns - but I'm just guessing at the settings - next step is to find a chronograph. It's such a relief to...

Re: TAU 7 valve & spring issues / trouble-shooting help

OK, great, thanks for the feedback. The replacement seal was the old-style, with the steel insert. I think the clue I was looking for is that your springs are smaller at the valve end. My spring is the same at both ends, and a pretty sloppy fit on the back of the valve flange. It's not centered very...

TAU 7 valve & spring issues / trouble-shooting help

I acquired a TAU 7 - it's from the 80s - in an auction and have been struggling with it to get it to run correctly. Thanks to this forum, and gwhite, I've been able to get pretty far. Initially, the valve and seal leaked really badly. I took it apart, and found crud on the valve seal - bits of loose...
