I'm working on designing a small project, a tamale extruder. The design is mostly tube and sheet, with the need to roll a couple funnel shapes and TIG weld everything together. I need advice on a SS alloy to use that is relatively easy to cut and machine and to weld, the best filler to use and suggestions on what I need to do for back purging or perhaps making a simple little purge chamber. None of the parts are very big as it's designed to attach to an existing feed auger setup.
Thanks,
Pete C.
