Stop in for a cup of coffee

AC problems by the dozen. Thought I would throw a charge in my Swinger and maybe go to a car show tomorrow. Hooked up the gauges, vac'd it down to 28". Added a little freon on the low side. Half a can, 3/4 then Boom!!!
Blew the hose off the condenser. Compression clamp not a worm clamp and hose onto copper line, no barbs. Cut the clamp off and the bad end of hose. Damn hose is too short. I need 3/8 soft copper and a flare tool. Go to Lowes and buy a coil then to Harbor Freight for a cheap flare tool. Fixed it up, vac'd it down, threw in a charge, pressures are 60/250. Duct temp is 50°. That will work. Start it back up for a test drive, get 50 feet from the driveway and Boom!. Blew the other end off by the dryer. Same deal, same clamp,same 3.8 copper with no barbs. Argggh! i THINK i WILL pull the line and take it to the local radiator shop. may be they will have some inverterted flare ends and can make me a new hose.
