o , icic
anyway.. i cooked up one of my ghetto HPA tanks here. got it pumped to near 90. i dont kno how much more itll hold and i dont wanna try now, cuz its night... and if it explodes then.....yea
its a schrader valve cut from an old inner tube. i get them unlimitedly and for free from my local bike shop.
i just put some electrical tape on the valve, drilled a hole in the cap and stuck it in there. it holds a fair but not so good amount of air, because im using a smart water bottle, but soon ill be using 3 liter bottles
NO LEAKS =]
