Thanks for all of the ideas. It will be awhile before all of this comes together. I have had the Boyle Dayton around for 25 years. Recently I was able to buy a glass cylinder, handle, and a cast iron china hat from a twin that was being parted out. Normally the base would sit on my cement floor, but in order to have my pipes underneath, I had to build a pad for it to sit on. I raised it six inches. I must say, it is a fun project. I was thinking about what ever I use for a gas look liquid, maybe should be something that wouldn't rust the cast iron pistons, and parts At the same time have a small amount of lubricant.
