I made a quick box fitted to the size of the stock that was going in.. one concern was white oak (and other oaks) react with iron and other metals,, the wood turns black.. I had the pvc parts on hand along with a few brass fittings (there is a vent valve on the other end) and the insulation.. steam supply is a wagner wallpaper steamer, gives a little more the 2 hours of steam per fill..
