I have the answer for your "air chuck" problem-
Go here to this link and order this very special air chuck
- It'll be the best $15 bucks you'll ever spend- Guaranteed!!!
A little history- I was getting new tires installed on my old motorhome years ago at a truck shop. When the tech was going around airing the tires he put his chuck on and walked away- I said "how in the heck did you do that?" He showed me this chuck I gave you the link to.
You merely push (or pull) the chuck straight on to the stem, until air is going into the tire AND THEN TILT it ever so slightly- it locks on and works like a charm. To release it, just touch it ever so slightly- it'll "pop" right off. The secret is: it has "fine" internal threads slightly larger than the valve stems it fits over- CLEVER-
I set the output regulator on my Porter Cable 150 psi compressor to my desired pressure, put the air line and this chuck on (with quick disconnect fittings), and go do something else-
If you have aluminum wheels, click on "Gemplers Master Catalog" link on the above link I gave you. They have a special "Lock on" air chuck for your use.
Good luck, Try not to get stuck anymore-
