I think i will still make a square one, but with curved corners for easy fitting of the Buna-N.
anyway, if i were to make a 1mm drench ard the block (straight angles cut), what thickness of the O-ring should i use? Thinking of using 2mm, but I'm afraid the water will run over the channel walls. so 1.6mm of 2mm?
Thanks!
