Solar Extractor

[Rosti]

Planning to build one this year, wont be processing loads of frames.
Any design tips and nice to haves from those that have already built / used one appreciated.
What is a good general purpose size?
What to use as the main tray - old roasting tin?

Roasting tin good...and make it big enough to clean up queen excluders...
