Well I had some time last night and I was able to finish up my stir motor mount for my HLT. I figured while I was at it I myaswell make it into a lid for the HLT at the same time.
I coated the wood with butcher block oil, i'm not sure how it's going to work or if it's going to put oil in my HLT water. It's food safe so at least if it does it's not the end of the world. After coating the wood has soaked up all the oil and is dry to the touch so I think it will be ok. I may spray it with some water and see how much of a film I get from it. Worst comes to worse i'll just cut another lid out and paint it or some other coating.
