Built one out of an old refrigerator compressor, a pickle bottle, a tin can and a piece of wood. It worked great. I could start with a bone dry brake system, and bleed it perfectly in half an hour and not get a drop of brake fluid on the floor.
Use gravity. And hook a vacuum hose to the open bleeder and use a blow gun and blow air past the end of the vacuum hose to create a vacuum to get things moving. i have had good luck with it. And you prob have the stuff hanging around.
I use this : http://www.amazon.com/America-5060-...446390981&sr=8-1&keywords=topside+oil+changer It is something I had purchased back when I had a boat. It's for changing oil on an in-board boat engine.
Problem I have found with vacuum bleeding brakes is that if the rubber cups in the wheel cylinders do not have expanders (older wheel cylinder springs act as expanders) you can pull air past the rubbers into the cylinder instead of pulling brake fluid from the MC. I prefer to gravity bleed or pressure bleed from the MC.
I tried one once and had a big problem with air being drawn in past the bleeder screw threads, even after using teflon tape on them to get a tighter fit. YRMV
I use a 12" piece of aquarium tubing, fruit flavored brake fluid, and a neighbor I hate for the vacuum.
