I've built about a dozen in the last year, some were destined for the burn pile before they went in the oven but for the sake of learning I kept going. I've since found what seems to be working for me but I'm always trying to improve and value critiques as part of the process of improving. Should have what I believe will be my best to date out of the form this evening, just letting it rest before filling the hose and letting it cook now.
