I picked up a pair of Gaskell & Chambers Dalex Cylinder beer engines.
Patent # 259283, man. aprox. 1950? (Any info would be appreciated).
Cork washers replaced with Teflon;
Ready for installation;
Sat in a box in the basement of about 5 homes since they were acquired in early 80's.
Now I plan to sell them or trade them for a stainless steel conical base fermenting tank/vessel or, if they don't go, I shall install them at home.
One reason I haven't used them all these years is that I never consumed enough beer to warrant an "Air In" cask delivery system (not wanting air-born contamination, of course); and, thinking that CO2 back pressure would push the beer through the cylinder flaps.
Now I am using Ball-Lock Cornelius Kegs, with CO2 back pressure around 5 to 7 psi. and it occurs to me that if I use taps that can be turned off and use a CO2 bottle, regulated to about 0 or 1 psi as a reserve back pressure I might be able to use the cylinder pumps.
If they don't sell or trade, I think I shall experiment with a CO2 bottle and see if it works with a small reserve pressure.
Has anyone tried something like that?
