Nice. Judging by the guide rod, I'd say it's an inlet (chamber) sealing valve. It would definitely benefit more from a larger pilot valve than a similarly dimensioned outlet (barrel) sealing valve, in my humble opinion.

Maybe pilot it with a smaller 1" sprinkler valve. :roll:

It does seem like you're catching more than your share doesn't it.

I think it's fine. It fits in the boot of your car, and it works.

Can't have any fun with it if you can't get the damn thing out of the house, now can you?

I seem to remember this being a hobby,...aren't hobbys supposed to be fun?

Good job! :thumbleft: :thumbleft:

Out of curiosity, how is it in terms of noise? I would imagine that with a 2 - 2.5" barrel it isn't too loud, everyone in the thread seems to have forgotten than smaller chambers mean more efficient and quieter launchers.

Free?!?! Now that's a great score!

Baha stop cursing? JSR, I never bloody swear.

Reminds me of my mum when I was young and she would catch my mates and myself swearing.

Mum: "Did I hear what I thought I heard you boys say? DON'T F***ING SWEAR!"

lol :D

Back on topic. Reckon any other tire companies would sell em' mate? I have a Bob Jane, a Jax and a Bridgestone near me.
