How many fill with a hand pump?

[ssbn617]

I pump because I have no money. Funny thing is a lieutenant on the local fire department out of the blue said he has an old scba tank I can have. Therefore, as of then, hand pumping is so not for me anymore , can you imagine pumping by hand? Crazy

\ Then bought tank and Shoebox F10 then Yong Heng.

Just curious... why did you buy the Yong Heng afetr you had the Shoebox F10?
I know the Shoebox requires a preliminary 120 psi compressor and the Yong Heng is a stand alone.. but was that the only reason?

Sorry for the thread hyjack in advance, but we are all here together here.. right?

Hand pump. I don't shoot enough to warrant an electric pump or tank and do have to mind the expenses somewhat with two in college now. Unless I'm doing some pellet testing or trying my hand at a target match, I fill the R10 once every couple of weeks.

Yong Heng fills much faster than my F10, is stand alone, and at the price point it sells at I decided to give it a try. I only use the F10 as a backup now.

Hand pump, now using 80psi in.  Really hard, but I need it.  34 pumps is all I can do at 80psi.  Funny, same endorphin release as was awarded from an intense swim team 800 back in the day, love that drug.  Difference is, recovery takes 20 minutes as opposed to a minute.  I keep threatening my wife I'm going to do it in my college Speedo.  I will probably move to a pump later on, but for now, I like getting off on the endorphins.

hand pump , but bought a yong heng and a 3 liter cf tank,, i shoot everyday now lol

Does the 80psl going in offer some advantage ?

of course, hes pumping 6 times the air per stroke that you are.

Can I do this without harming my new hand pump ?  I’m guessing your going to say it is easier on my hand pump and I feel sillier already ........

Rolling this over in my head I’m wondering about heat.........

Thank you very much by the way !

[Rob M]

no long term studies, but my guess is the heat generated from compressing that much air at that compression ratio is huge.. But , hes also not doing many strokes.. Im not sure how the heck he closes the pump after the first few strokes lol.. Anyway , I would do the precharge at 25-30 psi or so off a regged compressor for long term use, split your stroke count in half. ( ISH

  The old something for nothing rule...... always slapping me upside my head.

[Rob M]

theres a build thread on how to hook the compressor to the hand pump . it is something for nothing in the sense the compressor is run off electricity and not your back

I have a Maximus and use a hand pump. I'm only about 140 lbs but it's not bad. I'm a new land owner with a few acres and a good riding lawn mower is priority (among other things): no compressor for me just now.

LOL.... keep on pumping.. soon you'll be able to mow it with a push mower... 

Speaking of staying in shape...my father in law has been retired for many years now and has become something of a handy man for all his elderly friends (and some younger ones). That entails mowing lawns for people. I haven't heard how many are on his list this year, but if the last few years are any indicator, it's 13 or 14. On foot. Not bad for a 80+ year old guy. (I always forget the  odd digit--I'll ask my wife the exact number...) The standard Christmas present for him: large sneakers to wear out mowing lawns.

Back to closer on topic, I happened to note the effort to pump up the R10 last night after some pellet testing. (And I just filled it Friday or Saturday already...testing sure eats up the air.) From "really low", around 1300 PSI, I did two spells of 40 strokes, with a break between, mostly for the arms. Not particularly winding nor breaking a sweat. Then a few spells of 20 each. Somewhere past 2500, I checked my pulse after a spell. I had sat a moment and could already tell it was slowing quickly, but I don't think it had even made 100 beats per minute.

By about 3000 PSI, the real effort was required (As much as I hate to admit it, I'm around 140 lbs these days--would rather be under 135 even 130--the pants fit better then ). Had it been a little more humid, I would have needed a fan, but otherwise I was only slightly warmed up and the pulse was breaking 120 on the last spell. That's still not quite a cardio workout, but it does get the blood flowing and the arms pumped up . After 2500 PSI, the breaks are a tad longer too, as the pump is gets warmed up by the end each 20 stroke spell.

Geez, David, your weight is really spiraling out of control!

Yes, 20-35 is about right for supercharging.  I had dialed up the pressure to pump up my 95 year old father's bicycle tires for him, and forgot to dial the pressure back down.  I wondered why it was so hard to press back down!  But I got it back down, and then another and another, and as is always the case, successive pumps become somewhat easier.  Not easy, but easier.  Then I looked at the regulator's pressure gauge on the compressor, and it was at 80psi.  Not going to be doing that much.  About 65psi is the most I can do comfortably.

As for in shape at advanced age?  My 95 year old father rides six miles a day on his bike.  Marine aviator.  Still cuts his grass with a push mower, and his neighbors too.  I'd cut it for him, but doing it himself is a pride thing for him. Not about to spoil it for him.  Greatest, most humble man I ever knew.  He shall sit close to the Right hand of God.

I hand pump for 5 PCP rifles.
I am 74 years old and 215 pounds.
The secret is to pump slowly and take breaks.
When pumping the Gauntlet from 1100 to 3000, I usually do it in 3 or 4 sessions.
Pump 500 or 600 psi and take a break.  Shoot other guns, play on the computer, watch TV, etc.
Sometimes the pump will stay connected to the gun for 2 or 3 hours.
It is good exercise, just do not pump 1100 to 3000 psi on a 13 cu in tank without taking a break.

Yeah, that wouldn't work with my ADHD.

Thanks but I've already moved on. I now spent countless hours buzzing my dog with a $20 quadcopter.

Ha ha !  I used mine last night to send some gummie bears to my nephew while he was in time out 

I got A dirty look  from his dad but he declined my offer to “talk about it”.  .   Unk is kind of protective of his nieces and nephews  .   Unks house. Unk’s rules...........
