A while ago there was a thread posted on a homemade pneumatic booster pump using a hydraulic cylinder, but try as I may seaching for the thread I'm coming up with nothing....
Anyone have anything on this?

Boosters are not obscenly expensive, just buy one. I am usually not to type to say "you'll kill yourself" but high pressure air is dangerous. Plus the chances of contaminating your air using a home made booster.

Here is a link for a new one: Hydraulics International Compact Booster - Booster Pumps - Compressors, Booster, Gas Mixing, Fittings - O2 & Gas Mixing
Shop around and get one used, you'll be better off.

I'm pretty sure that the thread you're referencing was about a booster put together by Vance Harlow, username: [user]Oxyhacker[/user]. Here is a link to an article on his website, as well as purchase instructions for the book:

IMPROVISED AND LOW COST HP GAS BOOSTERS a new book from Airspeed Press

IMPROVISED BOOSTERS Excerpts

Excerpt from article:

My booster is built almost entirely out of scrap parts. Both cylinders, the frame members, and the powerpack all came from the scrap yard, most of it at 28¢ a pound, and the rest haggled for on a per item basis. The hoses and check valves are new, and the other valves and fittings are a mix of new and used. You take your chances, of course. The first cylinder I bought looked great, but turned out the cylinder tube was badly corroded inside.

I don't have time to search for the thread itself right now, but this might get you started, or just be what you need instead.

I have one for boosting argon. You'd be nuts to use it for O2 and boosting helium would take obscene volumes of HP drive gas. What do you want to know about them? Here's 2 rather old pics of mine:
