Thanks Crashlander I think your idea is what I had in mind and the way I am thinking of going. By the way where did you get the B&D retracts. I am not familiar with that brand. I have some old springair but I need a control valve,which will probably go with a robart. I have robarts in my P-47 and Ultra Sport. Had these springair laying around and thought would use them in the new chaos, if I can get them to work and you have given me the answer. Thanks.
