As there's epoxy involved you'll have to wait at least 24 hours to see it in action, but here's the whole thing in the meantime, obviously needs finishing.
Already looks better then my one cant wait for damage, how heavy is the blade part? With the plastic back it should be quite front heavy and hopefully make it fly straight.
When you do shoot it keep the pressure low and build up, the recoil is really bad at 300psi I need to hand to hold onto the thing.

This is quite small scale, I'm not expecting much recoil. Here's all the data in a GGDT model:

Yeah that lots smaller then my one, chamber is 19mm ID, 90mm long and the blade is 100ish grams IIRC, never GGDTed my before ill give it a shot now.

For the lulz I think I should post JSR's video before JSR does.

JSR is probably designing a less lethal device such as a phallus projectile for his next trip to Russia.

JSR has this year discovered he prefers to lavish his disposable income on machine tools than voyages to the motherland I think I'm growing up! Or not

jsr, that is awesome! if it would have little longer, dagger style blade, that has been heat treated springy, that would be deadly, and you would get little more fps with lighter blade

Are you suggesting a joint effort

If we're going to collaborate I'll start from scratch, this was just a rough prototype how much would a 5 inch or so version of this blade set me back?

The Fairbairn Sykes...what a surprise for you to choose that by the way if you have one of those FS knives made request a thicker tang, that 1/8" piece of steel is as I understand, a notorious weak spot.
Edit: Screw you guys, I'm gonna go find a spring

If made to be fired, a long tang is unnecessary really.

Noooo, pneumatics are so much better!
