All credit to him, looks like a good idea.

I have recently tried to find a alternative way to process 5 X 4 (I've been using a Doran tank - (similar to a yankee) It is the invention of the Devil!!! Infernal contraption, a pig to load, takes ages to fill and empty. I ruined several good shots last batch because you just can't agitate it properly, it gives horrendous flow marks ...)

I've lost two ebeegeeby auctions for Combi T tanks that went for huge money - and two auctions for Paterson orbitel processors that went for about four times what they probably cost new :-o

This guy seems to have a good idea at a much better price than a combi (which is nearly 90 new in the UK)...

Ah, but I've got some perspex sheet in the garage, and now I've seen how to make one...
