Yep, that looks about right as far as lever indicators go. You'll probably want a plunge indicator as well, though. And a couple of mag bases. Then you can make up some indicator holders for the lathe toolpost, and maybe one to clamp to the ways. For tramming the mill, all you really need is a piece...

Ah, very good to see you're still in the game! You can clearly see the "I grew up on PVC but I'm an adult with access to metals now" pedigree :D Got a bit fed up by the pull-rod trigger, and wanted to shoot it like a normal airgun.

I'm currently designing a "big bore" (9mm) piston hybrid, with on-board air and fueling. I should be able to get quite some shots from a 200cc reservoir filled to 200 bar if I stick to a relatively small chamber volume. The goal is to have big-bore airgun power, but not the outrageous air consumpti...

My new self-made short gun. It is a hybrid pistol, with a built-in air pump, that operates with 8x and five strokes only. It shoots common pellets, .22, and the firing barrel is 12 micro-ridged, 200mm long. My friend's chrono gave about 650 fps on 4.5 ml of butane. It weighs about 900 grams, and ret...
