Cut a plastic milk jug that is just a bit bigger then the transformer so that the transformer can be completely covered.? Under vacuum for 10 minutes should be good enough.

Hi Jim, Thanks for the tip on how to make a vacuum chamber!? That sounds quite easy.? There are plenty of industrial vacuum pumps out on ebay that might pump it down faster.? Or, if one has an air compressor with a fitting on its inlet, it might be put into service as a vacuum pump.? I'm fortunate to have a vacuum oven I bought at a laboratory surplus sale 25 years ago.? But the pressure cooker would be even better than that because if there is any leaking liquid, it'll just accumulate in the bottom of the pot where it can be easily cleaned up.? On the other hand, the vacuum oven has a window, enabling spectators to observe the proceedings. But how would one get the varnish in?? Immersion?? Would marine spar varnish work? Halden VE7UTS
