Yeah, that one measures to 50 Millionths of an inch or something...you have a heartbeat and the needle moves of your near the adjuster! LOL

Yes I was looking around and saw those too. Ran across 20 gram units as well which has me going Hmmm, again.

CarsonRatSniper · « **Reply #222 on:** November 21, 2014, 11:34:35 PM »

I saw the 20 gram too...but its too big around for our gauge manifold with the breech/tube band.

On this version

I've been toying around with a couple of ideas and the 20g might work.

Might just fit into a pistol grip............wouldn't it?

rsterne · « **Reply #224 on:** November 21, 2014, 11:48:06 PM »

The 20 gr. also has 3/8"-24 NF threads.... There is also a 25 gr.... no idea of the diameter, threads, or MSWP.... Next up from there appears to be 45 gr. but it has 5/8" threads so is a LOT bigger....

The 45g's are made for ATV and motorcycle tire inflators so take a larger chuck. The 25 should (Hate using that word) be the 3/8 thread they are made for high pressure Road Bike tyre inflation.

Now if it was a *side pumper* there'd be all of that unmolested forearm wood to hide something in! The only limitation would be OD but we could always make a different gauge manifold or an adapter LOL
Jim REALLY liked the side pumper idea and we're going to build at least one...I may just leave that as a user option after I can post details of the differences between the two.
I see pros & con's of both versions...

If we don't like the side pumper all it cost us was a Disco tube and a little machine time.

The decision was made to mill the loading bolt so that it's ambidextrous. Just unscrew the bolt handle and screw it in on the left side.
The cocking knob will still be on the right side...Norm is looking into an Ambi stock with the same depth at the gauge (or very close) to the Blaster stock.

Could even use that something in an offset config to balance the weight of the pump.

One thing that has had me curious in general is why in this day and age with uberstiff materials no one uses a telescoping pump arm.

rsterne · « **Reply #228 on:** November 22, 2014, 12:26:40 AM »

If the OD of the CO2 cartridge is larger than the reservoir (7/8") then the inletting in the stock will have to be wider as well.... leaving gaps along the sides of the reservoir when it is in place.... That was my reason for using a 16 gr.... invisible when installed....

Mike,
I was reading a thread in the machinist forum about your carbon barrel sleeving and was wondering if you got that all figured out?

lavahunter · « **Reply #230 on:** November 24, 2014, 09:06:01 AM »

I guess I'm a little late to the party and I thought I have read every post here but I don't remember seeing a price on these. Was it mentioned ?? thanks

The original goal was to stay under a $1000.

CarsonRatSniper · « **Reply #232 on:** November 24, 2014, 01:11:19 PM »

Yes, I have the cf sleeving figured out...

I *should* have a hard cost this week - Jim is working on all the little parts.

I posted a *Not to Exceed* of $1200...but I am trying to keep it under $1000.

Are those valves above have the same O.D. as a 13xx valve?

rsterne · « **Reply #234 on:** November 24, 2014, 01:36:36 PM »

No, the 13XX valves are 1/8" smaller than the 22XX/Disco valves....

Okay. I thought it was 22xx size.

Was wondering if you could run co2 in this gun for plinking? I run co2 in my airforce condor in the summer and it works alright with light pellets. Would be easy to make a fill adapter from my 20oz paintball tanks to fill through the foster fitting.

hutnicks · « **Reply #237 on:** November 25, 2014, 01:36:43 AM »

I was just wondering if I could cobble up some C02 system to pre pressurize the air res to 800 psi or so.

rsterne · « **Reply #238 on:** November 25, 2014, 01:48:15 AM »

If you want to run CO2 I would tether it to an upright bulk tank (no dip tube) so that you have only vapour in the gun.... Crank the RVA back to not waste CO2 at the lower pressures, and plink away....

Bob

jvanschoonhoven · « **Reply #239 on:** November 25, 2014, 01:51:58 AM »

I like where you are going with that.
I'm sure there is a way to do that just not sure how to make it happen.
I do basically the same thing when my scuba tank runs low I just top off with the tank then finish with my fx 4 stage pump.
