"dont burnish brass counter sunk valves and poppets. do some dry fires while filling, this helps seat new poppets." you guys need Billys plenum to fly to 60fpe land. send me a pm, ill make a list and send it to Billy when we have at least 15-20 interests. we are actually trying to see if its do able. when its a go, he will collect your deposits.[/quoteI forsee some gains in your future quest for power!So Billy, what's the word on the plenums?

I am sure he will be thorough. We are hoping for some meaningful performance gains. When the results are in, I'll do a cost analysis, project potential sales numbers and see if a production run is in order. For example....if I made a hundred, likely would have to sell eighty to break even in an attempt to keep a reasonable price. Programming, setup, tooling, machine time, etc, etc. If I made fifty, the cost would have to go up. Some people will want a bolt on 10mm nipple. Others may opt for a 1/2 x20 nipple for a larger transfer that will require machining the receiver. If I only sold 79, or 39, I'd be losing money. I am using some pricey material, 7068 aluminum. As strong as 6al4v ti, it was once classified, a controlled material and not common or known in most circles even today. I could use 7075 but the wall thicknesses would go up considerably, reducing precious plenum volume although they would be cheaper. I remember people asking JSAR to make special valves for some Hatsan models. There was a lot of talk but JSAR could not get enough commitment to go into production. We'll see if that scenario repeats itself, I hope not.

Pump, pump, pump with abandon.
It can be hand pumped but it does suk especially if going for a 300bar fill. I ended up getting a scba tank and a shoebox f10 so I didn’t have to hand pump anymore.

But not from Walmart. You have to return the item to the 'MarketPlace" vendor and wait for your refund.... believe me. I just went through it not too long ago.
It's nice to know that Wal mart will try to resolve issues even with outside vendors.
I thought this thread was a topic about ATI (Nova Vista guns)
In hindsight, if I were new to the PCP world I think I would buy a Maximus and a Chinese hand pump.https://www.fieldsupply.com/benjamin-maximus-air-rifle-177-cal-black.htmlhttps://www.ebay.com/i/173705984393?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=173705984393&targetid=541453965492&device=c&mktype=pla&googleloc=9012797&poi=&campaignid=1881504899&mkgroupid=66933536821&rlsatarget=aud-762207186714:pla-541453965492&abcId=1139336&merchantid=115308880&gclid=EAIaIQobChMIlNbzq-GY5AIV5JJbCh097QidEAYYAyABEgJxjvD_BwELess than $300 invested. If you decide that PCP is for you there are many upgrades and mods for the Maximus to keep your learning experience learning. It's a 2k fill gun so hand pumping will won't be sour grapes. The Disco is another option with a 2k fill.The Marauder would be the next level up if you are young and ambitious enough to pump to 3k.Anyone who shoots PCP would be wise to have a hand pump as a backup. The $50 hand pumps have been proven to be just as dependable as pumps costing 3x more.Shoot and learn while you're reviewing and socking money away for your 'dream machine'.
