If a suitable area can be arranged with a flat floor (maybe a trailer?) and access to electrical power, I've been discussing the possibility with another bolter of doing a demonstration of the rear main bearing seal machining procedure for the full circle oil seal. He will be bringing a bare 216 engine block to the show, and I'll have my cylinder boring bar and the adapter plate I made to fit it to the back of the block. I'll also have the spray nozzle aligning fixture for the 216 and early 235 oil pans.
