Continuing the discussion from Hay filter warning:
The saga continues… I’ve almost completely removed the thin steel pieces from the truck, as over the years every bit of it has failed dramatically. The one place remaining is the heat exchanger outer shell. I’ve resisted fixing this one because it’s so tied to the main body of the gasifier; however today’s discovery leaves me no choice.
This point on the gasifier takes a beating; it supports a lot of the weight of the gasifier and is forced to flex every time you hit a bump. Eventually the thin metal tore out around the weld. Anyone building a similar setup should have support feet on the heat exchanger, and weld some gussets around this critical joint.
At this point it looks like I’ll have to take this apart and beef up the whole area. I don’t have time to redo the whole unit the way I’d like to, so this will be a temporary fix, enough to get me through Argos and hopefully finish out 2015.
Bottom line - stay away from anything under 16 gauge metal! It seemed like a good idea, and has held up for a few years… but you WILL replace every piece of it eventually.
