Would a Shock pump make sense in this situation?

Unread postAuthor: maverik94 » Sun Apr 26, 2009 6:44 pm

Ok, I will get straight to the point, would a shock pump such as this one:
http://www.amazon.com/Buzzys-Pollinator-Aluminum-Anti-Leak-Inflation/dp/B000GJWK1W/ref=sr_1_5/176-9139132-8029329?ie=UTF8&s=sporting-goods&qid=1240788249&sr=1-5 be better than a foot pump for pumping up the chamber of my gun that is about 14" long of 1" pipe, and 16" long of 3/4" pipe to about 60-70 psi? Thanks!

For 60-70 psi you could probably get by with one of those crappy electric tire inflaters. No reason for a shock pump at those pressures.

For 60-70psi you could probably also get away with a hand pump.

But who really wants to do that, get a cheap track or foot pump if all you need is 70psi.

Don't use a shock pump. It took me around 10 mins to get a 600ml drink bottle to 50 psi. Go for a track pump, foot pump or small compressor.

Maybe you could use something like this.
I have one similar by the same company and it will pump up my launcher to 80psi in 25 pumps. great for building up your muscles too. :twisted: :twisted:

here is the launcher in question

Don't use a foot pump, unless you get an expensive one they are well inferior to a track pump.

That's the point. I can get them over here for $10 aud from hardware stores. Not the most brilliant pump, (rubbish next to a track) but fast, easy and dirt cheap (no innuendos). When they're stuffed rip the rubber off for a sealing face (if suitable), take the guage, the pipe, the chuck and if aluminum melt them down in a forge.

That said, a track pump is a better investment and a better option.

Edit: That said, I use a huge 3 phase shop compressor or a shock pump for my guns.

well, here is the gun in question:
Image
I put a normal 12 oz. can of soda next to it for scale. We are getting a compressor, but I would like to be able to have more mobility than that. I have a foot pump that will pump it up to 50psi in about 30 pumps, but I would like something a bit faster. What are my options besides co2, nitrogen, green gas and all those expensive bottled things? Any ideas?

What is wrong with just a bike pump? yea they are a bit less mobile, but honestly, your not going hunting with this thing, your not going to like run through the brush with it 9 times out of ten, so just buy a 30$ bike pump with a nice gauge on it.

Something like THIS

It's honestly the best solution. If your really worried about mobility, then use some hose clamps to put a shoulder strap on it, that's what I did with mine.

That should get your gun to 100 in about 7, I have had bigger chambers that fill much higher much quicker, its a much larger volume in that pump versus a foot one.

With that tiny @ss cannon, I would say only about 5-7 pumps to get to 60psi (depending on the actual pump you get)

(minor EDIT: tiny @ss not meant to suggest crappy, just size)
My cannon is about 3 feet of 1 1/2 pipe, and at 15 pumps I'm at 150 psi
