This is somewhat a continuation of my Kwiky thread. I started out with 40 light (3500°F) density IFB’s ( 2 1/2” x 4 1/2” x 9”) and one roll of fibre blanket (2” x 24” x 150” 2300°F). I want to build a decagon (10 sided figure). I want everything easily replaced And somewhat capsulized. My goal is to keep everything.... - portable (keeping weight somewhat down and mobile) - one man operation - keep operational costs to a minimum - somewhat rugged - furnace being smaller than (24” x 24” x 24”) - crucible size, I didn’t care about. - burner I wanted simplified and as small as it can be... i’m OK with having two burners. - only 1=>15 amp circuit that provides electrical power. So disconnecting one common extension cord would shut down everything. - very little, screwing around with mortar, Applicable refractory cement.... - minimal waste, with minimal work requirement for replacement parts - primary heating source being diesel for pre-heat and WMO/WVO being primary heat source It became a long list of requirements. The simplest, became junk 24” barrel cart. With handle. - some stainless 22 gauge steel offcuts for the lid. (I had to plasma cut them) - I fit some 12 gauge base with the plasma cutter as well. The lids will get drilled as an assembly, and toe clamp the lid IFB’s. I will mortar the lid IFB’s, And add the high temperature fibre wool to the top and sides of the lid. The sides and the bottom of the furnace will be lined with IFB’s and lined with the 2” fibre wool as well. The outer shell will be finished with 22 gauge stainless steel. All the IFB bricks will be held in place with hose clamps. ( yes I, I did drag my big 2200lbs. sander into the driveway for fitting, but files are somewhat too large for this post. ) The stainless steel straps/hose clamps have a maximum diameter of 17 3/8” This is my build!
