Travis. This propagator is some 40 plus years old it came with the gardener I married. Though on this side of the pond we Brits are a race of gardeners and heated propagators are available at every garden centre. In your case ebay do seem to have a number for sale so a look there will help you. As for the propagator they are usually between 60 and 100 watts available in many sizes.
Ahall. Yes I have tried a vacuum method to remove oil from a gun stock it is possibly the quickest safest and best method of all. The unit I used was built for use in a production line to impregnate high voltage transformer windings with an insulating resin working the opposite way around with the transformer placed in the tank of resin then the vacuum applied removing the air from the transformer windings then the vacuum was removed slowly with the resin now being drawn into all the spaces. In a period of down time I placed a oil saturated gun stock in the vacuum chamber applied the vacuum and the oil poured out. I did think of building a unit to do it BUT! To produce a good workable vacuum the cost of a two stage high vacuum pump made it impractical, at the time about 800. The chamber to place the gun stock in could be constructed out of 1/2 inch Aluminium plate and bolted together using rubber sheet as gasket material. The chamber construction has to be capable of holding the vacuum ideally permanently because continuous running of the pump will shorten its life rapidly. In short I did it a number of times using a commercial unit and it worked like a dream but to construct a high vacuum chamber is not cheap on this side of the pond. Should have also said that some form of heating is required for the vacuum chamber to get the oil to flow easily though this being the easiest thing to do.
