The only problem I could see is that the WB's can put a lot of heat out and if you roast load gets to large you may start melting/warping the top. I have heard some on the list remove the entire top plastic and replace it with a open ended can. They roast outside and let the chaf blow (Les I believe, among others). Over all, try it and see if it is a problem (I hate getting that kind of advise, but....).I doubt it will be much of one. -- -- John Nanci AlChemist at large Life is too short to drink bad coffee.
