Title: What to do with a left over P-Rod tube?
Post by: stevevines on March 02, 2023, 07:43:17 PM
Add more parts, that's what!

(https://www.airgunnation.com/attachments/1677760128970-png.336679/)

Ordered a 4-48 tap from McMaster-Carr and tapped the tube for a Disco breech. Utilised a Maximus valve, an 18" .22 caliber barrel, Challenger power adjuster, 4500 psi/1800 psi output reg, and a 3000 psi paintball bottle.

The original goal was to build a "loaner" airgun capable of lots of shots at decent power. We'll see, should be some good shootin' weather this weekend, hope to wring her out & see what she'll do - 8)

EDIT: Almost forgot - a totally un-authorised collaboration on the stock between Tom West and BuckRail

Had time this morning to see where this build is at: first shot was at 770 with Crosman 14.3 -

After some twisting on the Challenger power adjuster, she peaked out at the low 840's - so I backed off the pa and now she's at 825 or so.

20 shots across the chrony used approximatley 500 psi of the 13 ci bottle. Will go for some scope time later on this weekend, and maybe a full shot string to see what I can get out of this set up before she falls off the reg.

Can you elaborate on the stock?  I'm looking to build something bottle-fed and this works for me.

Thanks

Well, hope this doesn't go to the A.R.K.b but that is a Tom West P-R0d stock with a Buckrail P-Rod forearm. The stock was promoed to me be Tom when another was purchased. The forearm was chopped a little to accomodate a drop block, plans changed, re grouped for this build with a Buckrail forearm.

Thanks - I'll either have to keep looking or come up with my own solution to hold a bottle.

Do I see a ASA on the bottom of the pistol grip?  That makes sense to me.

Post by: stevevines on March 05, 2023, 04:07:40 PM
Yep, a kid at a paintball shop gave me that over 10 years ago, just now getting around to using it.

Give Tom a shout, email urgthrash.com

I have no doubt he can come up with what you need.

If you can source a drop block, he could build you one of these stocks if using an asa adapter doesn't work for you -

I've done similar with a couple of CO2 to HPA conversion on some full-auto BB guns. 

What presure are you running and what hose to the Prod air tube?

I didn't find any 2-3Kpsi rated hose for PCP use.

It is very satisfying to look at your spare parts and realize there is a cool gun waiting for your to assemble it.  Great job.

It's a 10" 3000 psi rated hose, bought it at a dive shop, came from a scuba yoke, and I put heat shrink on it. The reg is a 4500 psi input/1800 psi output paintball type reg.

EDIT: also sold as braided steel hpa paintball line

Tim at Mac-1 has it. I remember looking for some a while back and it wassurprisingly hard to find some that has pressure ratings stated,  rather than a vague "for paintball use".

I could have used the hose from my old scuba tank yoke, but it was too short. It's the exact same stuff, SCUBA pressure rated braided steel line. The trick is to find it in a 10" length.

Yep, it's funny you mention that - I have a 1701 tube, just need a valve, have the rest . . .

It is fun cobbling together from misc parts ...
This having a 1701 short tube, ah reverse bottle version  :o

Very cool MH! Thinking of doing something similar with the fill port on the build, the difference being adding a pressure gauge -

For the BB gun conversions, used stainless steel hose, but was very short.  I never found a pressure spec on it though, just the "paintball use" statement.  Which I am assuming is probably good to 1500psi or so.  I have the regulator set for 850-900psi with a lower pressure burst disk.  I did try the plastic macro hose, but in short lengths and for my use, had to many leak problems. 

Using the asa adapters, I can go from a gun mounted tank to a belt mounted tank with a fill hose.  I also use it on a P1 pistol. 

The paintball stuff, I'm still a bit leary of using at 2-3Kpsi.  If I decide to bottle a 7/8 tube, probably will try to get a gaunlet drop block.

Many ways to configure Prods/1720T/1701's.  It was my main obsession for quite some time.  :)

I've found some tanks come with an 850 psi output.  And there are regulators that you can buy separate as well.

The regs and bottles was not the issue.  Back when I was considering a similar build, the ASA adapters were all low pressure, and the hose rating not known.  Don't get me wrong, the Prod can probably do allot with a reg output of 1100-1200psi.   I was looking for something higher at the time.
