I have finished the restoration of my Dunham Air Eliminator 220. Everything is original except for the check-disk, brass plug and stainless steel screws have been updated. I tried to match the color the best I could from what I saw on the metal to be the first and original layer of paint.



Now I have to install it!

    Dunham

    I wonder...should this be labeled as NSFW? Looks awesome. You'll get another 100 years out of it now.

    100year

    I know. I was going to use brass fittings but stopped myself at the plug. This stuff can become a bit of an obsession. I had the realization that I will be long gone and this thing will (hopefully) still be working.

    Installed!

    I finally re-installed the air eliminator as well as replaced the nearby rotten pipes. It was 60 degrees here yesterday but now we are back to 25 here in Michigan so I will be firing it soon. I have a crossover trap to install which I just got in the mail yesterday. Cross your fingers and hope I obtain a least a couple inches of mercury!

    It should work great,

    as long as my 90 year old valves, pipes and fittings don't have any leaks under vacuum. That will be next years task [ :) ].
