@NickDlow - Will be happy to make you one with a granite bottom. I have several colors of the solid surface counter top material from which to choose. Will find something that looks good together with the wood.
@JJ420 - I know what you mean about the glass/hybrid heater cover. Made a mini with a glass/hybrid cover recently that just performs so well. It does take more hits to finish a tube, but they all taste better. The one additional hit I get from using a ss heater cover unit just doesn't taste that great. Nice to have both a ss and a glass/hybrid units available for roasting. I have never sold any glass/non-hybrid HI's as I wasn't happy with the performance.
@ZC - I have made a GTV using a 14mm glass joint, but not a HI. I'm not sure the HI would have enough power to get the glass hot enough for the roasting tube. Most of the heat would just go into heating the glass. Suppose I could make a wooden version of the GTV using a 14mm glass tube.
@Gandalf - The koa wood looks great. Can't wait to turn you a HI.
