Mini Compressor

[cornishjoinery]

Hi guys,

I watched an episode of 'this old house' recently and the old boy Tom, was fitting some flooring. To fit the base trim around the expansion gap he used a pin gun and a compressor the size of a Thermos, (it looked like a Thermos and had a jacket around it). Has anyone used one, got one, seen one?
Looks brill for small jobs, where you cant get a compressor into the clients house.

Many thanks

Could it have been a separate compressed air receiver tank that you fill from your compressor and then take on site? They come in various sizes but I've not seen one quite so small as a thermos. Could have been something meant for paintballers?

It's a CO² regulator that you fit to a paintball tank ... http://www.amazon.com/Trinity-Regulator ... B00JVVW9HQ

...ah, my second guess.

I've got a small compressor, and I can fire around 30 headless pins from that before it kicks in, less in 18ga. I can't imagine how many you could fire on something as small as a thermos sized anything. Is there some physics at work here or am I really imagining 5 nails and then off for a recharge?

The refill 24oz tanks are reckoned to have a 1000(ish) shot capacity with a paintball gun. Not sure if that would translate to 1000 nails though?

I know some farmers that use "air pigs", Converted gas bottles, for things like inflating tractor /trailer tyres.
Same thing could easily be done for a nailer. A 7kg bottle would give 12 litres * of air (a 19kg bottle would give 35litres)*.

Approximate values ad it depends which gas the cylinder was designed for due to differing compression ratios

every chance that it was CO2. it stores at around 800psi, (thanks in part to being compressible to a liquid state around that point) unlike oxygen (and nitrogen and all the other gases that make up air) which don't. so assuming he was using CO2 in an 88g canister then a small canister is going to give you a fair few nails at 80psi. or he could be using a very high pressure air receiver, air rifles run at around 4500psi to get a similar amount of fires at CO2 from 88g. neither are particularly easy to charge and both have their own issues (like scaring the crap out of me in the case of air at 4500psi in a small bottle that can easily have the regulator knocked)

As soon as air pigs were mentioned I just knew that picture would appear, I was going to post it myself.
