I reassembled the cylinder 'under water' in a tupperware container filled with brake fluid as I figured it would be hard to bleed. I set it on the drill press. A quick test using a deep socket in place of a valve spring showed very responsive reading fron 0 to 80 lbs. I thought I had something I could use but had to go in for dinner. Now I'm thinking about 40 psi... is that the same as 40 lbs on a scale? Oh well, I'm learning new things and that's what makes me happy. Hoping to have some free time tomorrow to further investigate my apparatus.
