Here there is an arrangement for a convenient dry plate coating table, that I started using.
The side margins are elevated (trimmed) 0,5mm over the glass plates, the necessary gap to get the desired coating thickness:
Also the side walls (1cm tall) avoid emulsion spill, and the emulsion that's in excess can be recovered at the end of the table.
I use a silicon (cooking) mat under all, as recommended by Denise, basicly it's the arrangement described here:

Just I add a side guide that's higher than the plate to trim the emulsion thickness, and I also add the side wall to prevent spill.
I get good results by dropping emulsion pretty hot (55ºC). I also found very useful to previously apply vacuum to emulsion to get rid of any air bubble and then taking emulsion with a syringe.
Emulsion get cold/gelified anyway because there is a thick (1cm) glass under, in some 7min.
Next step is closing the table top with plastic curtains and injecting HEPA filtered air to get rid from dust...
Fell free to add any suggestion...
