Has anybody ever used copper and flare fittings to build their own vaccum rig? It would be cheaper than buying all the hoses ect. I don't see why it wouldn't work other than over time the soft copper getting more ridgid and more difficult to bend than hoses. I have everything on my truck to build it on my truck and I've already dropped some serious coin the last few months on new equipment. Tge appion 1/2 or 3/8 hoses are $50-75 a piece and the vac gauge coupling is ~20. I know I'll still have to get appion crts at ~$50 a pop but I can probably swing that and add hoses later. I guess I can just use my 1/4" hoses for the time being until I can aquire the larger diameter hoses. Thanks for listening to me think out loud, opinions appreciated.
