Warning; I am new to the group and I post alot. I hope others dont mind a very questioning person. I will try to maintain my focus. I have posted alot over the years in the Master Window Cleaners of America forum and use the Bimmerfest group alot. Owning 3 1995 BMWs and now breaking into my first what I would call heavy work (318TI control arm bushings) I can not help but wonder at what level of immersion into shade tree mechanics it becomes advantageous to invest in the compressed air technology. I could see popping off my frozen ball joint in two minutes with an air hammer, wheels too. I have worked on oil pumps, water pumps, hatch shocks and alot of other light weight jobs so perhaps it may not be in my best interest but perhaps I want to do more ball joint work or just want the luxury of having strong air fast for my tires. I just cant help but wonder about this (to me) exotic form of power. Could you get started with pneumatic (basic) toos and compressor for under $1,000?
