Power Plenum ~ Taipan Veteran

My gun will arrive early next week. Really looking forward to stepping up from a Marauder, not to say I haven't had fun with that gun. I haven't set up a regulator, is there a gauge on the gun that shows it's set pressure or is there a tool to buy to check before assembling the gun? Anything else fun I should know or play with besides lining up some ground squirrels? This has been a very informative thread. Thanks.

It doesn't come with a regulator gauge. The regulator itself is usually marked with the pressure set at the factory in Sharpie. I have chosen to install a Huma regulator as they take up slightly less volume in the air cylinder (and because I have a Huma reg tester). I think the Lane regulator testers would work with the Taipan reg, but I'm not sure. You could have one made or even make an adapter for some other tester.

Lastly, Ernest Rowe has photos of where he drilled and tapped a manometer in one of his plenum extensions. This also would be a good way to solve for the problem.

How many turns in order to increase taipan veteran regulator 10 bar ??

Is it 1/4 turn or 1/2 turn ???

I haven't reg tester .

I had heard that every "dot" from one sode to the other is around ~2-2.5bar, so perhaps 4-5 turns counterclockwise.

My my Derrick, what a massive plenum you have! The next time you see an Impact you can exclaim “that’s not a plenum, THIS is a Plenum.” Nice job!

That's the baddest, Taipan Veteran of all-time! Can't wait to see the shot string on that beast. I hope we get to see it at RMAC 2020!!! 

Hmm...if I filled the extension tube on my PRS stock full of lead on my Flex, maybe I could balance it out enough to put my mrod air tube extension on as a plenum. Of course, a puny guy like me would need a hand cart to get it in and out of the house and a hoist to shoot it, but for an exceptionally small ES and SD...it is something to consider.



Keep 'em dropping, Derek. My rate of learning has been rapidly increasing

My Vet's poor little factory brass valve body has about had it. I've had to resurface the sealing face on my lathe a couple of times after it was getting little magical scratches that were causing slow leaks, but the material is worn down way too thin since there wasn't even a lot of material there to begin with.

Being an idea man armed with said lathe, I went ahead and made some new ones. I've been using this rock hard 485 marine brass, and it's been real difficult to get my test valve poppets to seal against them. So what I finally decided to do was make one with a head that was a little bit longer than the factory head, except I added a generous little countersunk chamfer / taper to it for increasing the sealing surface, and I added some chamfer and grooves for the tube connector to mate to real aerodynamic-like




After porting it out and notching the bottom for the set screw, I threw it in and did some tests with a couple of different valves that I made. Sure enough, they all sealed perfectly. The one that I had thr least hopes for in terms of performance delivered 15FPS more than the other one and the factory valve lol. Now here is the AWESOME side benefit - since the head length is longer, it naturally tightens up the valve spring - and my shot count just about DOUBLED from what I was seeing before. The rapport is also substantially less than where it was. 

Getting late here now, but I have a some crazier ideas that I need to work on this week to take it to the next level

yes... that is certainly stunning. Nicely done all the way around!

I finally got my Vet. So much fun, almost too easy to shoot well with. What did you guys use to mount your bipod? Is there a nice kit to mount into the stock? Has anyone used a threaded brass insert? I've only been able to put about 30 shots thru my rifle at 30 yds just off a towel. GS beware! 

I'd like to get up to that 60 fpe range as well and sight it in at 50 yds.

I made the second prototype adapter tonight from the 3 different ideas that I've had. The features of this one are primarily around removing the integrated liner seat at the breech end, to provide flexibility in "mating" the breech and end of the liner with the factory aluminum transfer port. 




Pretty anxious to test it at paper using various tensioning methods. I'm equally anxious to figure out if the difference in the projectile seating depth will improve or degrade the Taipan's performance. Thus far, I have not had any noticeable issues with harmonics using the solid brass design, but I do want to run this one through similar paces to see if any issues manifest.

Congrats! On the pic rail, I get something like this: https://www.amazon.com/Magpul-MOE-Rail-Section-Black/dp/B003F6IQEI/ref=sr_1_8?dchild=1&keywords=picitany+rail+magpul&qid=1581009636&sr=8-8

I square everything up and drill some pilot holes and then use some stainless wood screws. 



I used T-Nuts to mount mine.

Thanks for the 411 guys. We should turn this thread into the definitive guide to the Veteran. Real happy so far, looking forward to polishing up some of the internals after I play a bit more. It's warm out and I have a day off tomorrow, hopefully I see some GS out. I can see they've been real busy digging.

I'll print a few soon in 22 and 25 cal

@mtnGhost

Put me down for one in .22!
