Thanks for all the great responses and input from everyone...Lots to consider.
For the moment, I'm thinking I'll try something along the lines of what Sundog made. A few questions about Sundogs design that hopefully he can chime in on, or anyone for that matter.
Since I'm all medium equipment, there is no reason for my design to even consider accommodating deeps. I'm thinking four frame radial with the bottom piece being very similar to Sundog's design. Thinking I'll go with a hole or slot close to the shaft to accept one of the top tabs of the frame with maybe dowel rod bumpers to support the bottom of the frame.
For the upper plate I was thinking that a circular piece of wood with a much smaller diameter with 4 slots to hold the opposing top tabs of the 4 frames would be sufficient. I'm thinking support from the top plate wouldn't have to extend to the bottoms of the frames since the bottom portion of the frame would be slotted in place on the lower plate....is this a bad assumption???
I notice Sundog uses a smooth shaft...wondering how he holds his top plate in place after loading the frames. I'm considering using a threaded stainless steel shaft which would allow for some type of Wingnut or something similar to hold down the top plate after loading the frames. Is there a reason to avoid a threaded shaft, or does this make sense?
I plan on using this in a food grade plastic barrel..Assume I would need to coat all wood and metal with a food grade epoxy or some equivalent...is this accurate. If so, suggestions on what "exactly" to use would be appreciated.
Concerning DC Bees suggestion....I'm not against buying a ready made basket, just haven't had luck finding what I'm looking for. I have seen some, but most small ones seem to be a tangential style, I really want to go radial...I'm thinking that's a better design.
Any thoughts and input is appreciated!
