First single stage, a few questions.

those compressor are common arnt they matty
what current draw does it have on the label mine have below.
1.1A @ 240c 1/5Hp ??
1.39A @240 1/4Hp ?? guessing here.
any compressor in series does a nice vacuum.
replace the oil with mineral oil and it last longer.

I'm pretty sure they have mineral oil in them. The are spuing out a clear odourless fluid which is just a bit thicker than water. The lables on the compressors don't have any information about their current draw or anything else much. Just that they are both for R-12 and 115V at 60Hz. It doesn't really matter what they are though, so long as they pull a nice vacume.

Well here is a but of an update for anyone following this.

I have tested the home made vaume pump on an Ice bath and was able to make it boil, so it pulls at least a 4600 micron vacume. Deffinatly enough to get all the moisture out of the system.

I got a flexible suction line and brazed that on. I then found out that the cap tube I had installed was clogged. I assumed I had brazed it shut at one of the joints I had made and tool them appart, but it turned out there was a clog right in the middle of the line in an area I haden't even touched :brick: There is a lesson learnt the hard way - Check your captube before you braze it on -

I brazed the suction line and eveything back togeter, with only half the cap tube just to check for leaks. I made an addapter to go from a big BBQ propane tank to a gauge set, and connected it to the evap suction line assembly. I stuck it in a bucket of water and gave it about 50psi. I may of well stuck a straw in the water and blown bubbles. I guess I shouldn't have cleaned all the brazing material of the side of the block, as the thing leaks like mad now.

I cleaned up the block and tried to braze the joint again. It went ok, but after it cooled down I realized I had burnt a hole through the copper pipe coming out of the evap. The thing is such a mess now after being heated soo many times that I may just start fresh on it. Even if I don't do that, I have to cut the top right off and clean everything, and put a new top on it.
