Back a couple months got a furnace carcass from another member, and have been picking away at it in-between other projects.
Set the base up on solid concrete blocks to keep it out of the damp. Bonus is this also gives more distance for coal bin (later on; it will run on a teat dip barrel for now.)
Welded on the new cleanout flanges, and made covers. Covers of 16g with 3/4" wide 1/8" flat stock bent around flange. Don't look too hard at the welds
but they aren't going to come apart anytime soon! Using Kaowool paper for gaskets on the cleanouts, had some around for the oil unit. All other gaskets are being renewed as well but with woven/braided fiberglass. The flat ones especially (on the stoker mounting plates) installation is much easier with peel and stick gaskets.
You may note required lubricants on top of the heat exchanger: copper antiseize for bolts, finest imported Canadian thought-improver for the assembler
I still have to replace the gooseneck bushing before I can assemble the right side of the furnace. That, and some new washers, is this afternoon's project.
When assembling the jackets, it works best to apply the rear and front to the base first, then apply the sides. This furnace differs from the older unit I have from the scrapyard: the blower section is totally separate and has its own base--the older unit, all on the same base.
You may notice some color mismatching; I used Rustoleum "Royal Blue" as topcoat of rusty spots (taken to clean metal and primed). Close enough.
When wiring the blower, is it necessary to use stranded wire, or is solid acceptable?
