I'll do my best to describe it, since I didn't draw it out. I ended up going w a bit simpler design than my original plan also. To preface, I have a 62 qt Bayou Classic pot with the basket. Currently when I'm done mashing I pull the basket up by hand and have a buddy (or fiancÚ) put a stainless steel grill grate that fits exactly over my pot down, and I set the basket over that.
Anyway, my stand will be 16" wide x 16" deep. 24" tall. The stand will basically be a rectangle
. I opted for the 8 hole angle brackets which ate probably overkill, but why not
There will also be a strut piece across the front and back, about halfway down. This will have a piece of metal across it making a shelf for the banjo burner. I'm then mounting a piece of 10' strut to my garage ceiling. They make a "trolley" that has wheels and will slide within the strut channel. My plan is to hook up a motorized hoist (harbor freight $100) to that trolley and could assist brew friends lifting their bags out, etc as well as my own.
I will post the parts list of what I would have used if I attached a BIAB arm to the stand to help with lifting the basket out. I would suggest looking at their wing fittings, angle fittings, and shelf brackets and I guarantee you could envision any number of arm designs that would work.
