"Go to an air/gas supply house...or welding supply shop. One can get what they need"
Wild Card, I called them and they said I would have to lease one of their bottles which would amount to $137.00 for a lifetime lease with a refill costing around $25.50. I currently have an Argon bottle, an Acetylene bottle, and a Oxygen bottle from them, so I am not new to this process. With my health problems and the fact that I turn 70 soon, I will just stop by McKnight Tire and Auto when I make my VA visits and fill my tank for free. Thanks for your suggestion.
Bill.Satellite, he did just that, I watched the whole process. I entered the maintenance field in the Army in 1969 and retired from the maintenance field in 1993. During this period I spent 19 months, six hours a night bouncing (installing) tires and performing all types of repairs that were offered by Manny, Moe, & Jack(Pep Boys)on Hampton BLVD, Hampton, Va. No, we didn't use nitrogen then.
