    I would like to convert an old style bbq grill propane tank into an air tank that I can take down to the gas station and fill with air and have around the house to fill up bike tires top off car tires etc.. I guess if I had a compressor I wouldn't need this...but I don't.

    How hard would this conversion be? I've never really worked with air fittings before. Any body tried this?

    Thanks.

    I've seen kits in the past to do just what you want.

    Easy to do, unscrew the valve, insert a short piece of pipe, a 'T', reduce one end down to a tire valve fitting; the other end of the T, convert to an air line. No air compressor is going to produce enought pressure to explode the tank unless you have access to NASA grade equipment.

    I've got one that I use on a hobby air brush - works good for that.

    I'd suggest buying a small cheap air compresor though - I've seen them at discount stores for about $50 and they're so much handier around the house than an air tank.

    I have several of them. Takes awhile to get rid of the smell though. I use the standard fitting with a quick coupling for charging it and using it.

    You can rescue a small compressor from a junked old refrigerator or deepfreeze. I used an old deep freeze compressor for two years of running an air stapler for nailing cedar shake roofs.

    Be cautious about careless handling of the oil in the compressor.
