I could try that. But rather find something easier to do! Does something like clear hosing work just as well?

Went ahead and made a few changes including:

- Cut the barrel down by half. So it's right around 12 inches now.
- Made a larger chamber/ air supply. (4 inch in diameter, 14 inch in length)
- Created a breech in the barrel with a dremel tool.
- Tried to find/make a sleeve for the breech.

So ...

I'm limited on tools so making a hole maybe a challenge but I'll try and find a way. And just find a sleeve that fits snuggly over the barrel and slide it over the breech hole? No o rings or anything are needed?

Thanks!

I want a cleaner look so i'll grab some PVC and throw together a 4 inch x 12 inch chamber. About 5 times the size of the 48 inch long ones.

I'll chop the barrel down today and see how that works.

And if a blow forward bolt isn't exactly ideal without changing too much what could I do for easier ...

Got it right on my first guess after playing around with it for a little bit! Fired a few and had fun with it.

Would load the chamber with around 60 to 80 PSI each time. Found a few leaks but took care of them right away. I have some trouble getting the female and male quick connects to lock in ...

Just got all my parts together and I'm sorry for the double post but I have a quick question. I feel dumb for asking it but I don't want to mess it up. Which way should the slide valve be facing or which end screwed into the QEV?

Thanks guy!

I guess I did. I asked that question when I didn't have the CPVC in front of me. So it would work to use the CPVC?

The outside diameter is 5/8 inch. I bought the CPVC at Menards Hardware Store. The tube says it's 1/2 inch. SDR-11. NSFPW. 100 PSI @ 180 degrees F. 400 PSI @ 73 degrees F.

All i'm saying is the CPVC would be better but I don't believe it's pressure rated.

How will I connect the slide valve to the female quick connect on my main air supply?

Also for the barrel to QEV connection I was planning on using a replaceable barrel. So it'd be a 1/2 inch female to 1/2 inch male correct. Male end screws into QEV.

Does the barrel need to be pressure rated? Like ...

Thanks guys!

Could someone explain to me the fittings for all of these?

The QEV are all three female half inch correct? So i'll need male half ...

I thought it was diameter and length you factored in? Must of mistaken what you told me! Oops.

Is this a horrible thing or will it just mean I have a lot more shots to use?

I can always cut it down and get a few more end caps.

Thanks for the input and past experience. Had some time to talk with some other spud filers today and was told to go with a 2:1 chamber to barrel ratio. I went out and made my chambers tonight.

Barrel: 1/2 inch in diameter and 24 inch in length
Chamber: 1 inch in diameter and 48 in length.

Going ...

That's what I'm planning on doing. Using a PVC chamber instead of a soda bottle.

So two liters is around 125 cubic inches. V = 3.14*r^2*h

I figured going with a 4 inch diameter and that would mean I would have to get around 10 inches to have a volume of 125 cubic inches. Does this seem right?

And I had talked about a schrader fill valve for the ease of portability but if I ...
