I doubt anyone of us can buy one. Will be too expensive.
Just an observation. All SS, double walled cylinder, double walled heat shield, looks like a solid machined handle, looks like cast iron bottom. Just on the SS parts and custom labor work involved would make this very expensive.
If i have to purchase all the parts at retail, it would cost roughly $150. Probably would take me 4-5 hours to put one together considering the limited tools at my disposal. Angle/die grinder, table vise, vise grips, drill, hammer, socket/wrenches were the only tools that i used. By far the most challenging and time consuming potion was manually bending the 10 gauge perforated steel.
So yeah it cost nearly 10x as a Weber chimney but it's all worth it. Labor is free since i find making my own things to be very enjoyable, relaxing and most importantly, rewarding. Extremely proud on how it turned out on the double heat shield and even more so on the handle/strap assembly.
And oddly enough, not a single part/item were purchased with the intention of using it to build the chimney. Parts were either purchased for something else or something that i already have around the house.
