[labnetwork] ALD reactor thru wall sealing ideas

[James Mitchell]

I have had to cut through a honeycomb wall like that. Once I had the
opening I needed I used a large piece of tubing to insulate the opening.
I got 2 or 3 inch OD soft plastic tubing and cut a longways slit in it and
fitted it around the opening.
This would make it safe to reach through. You could also use silicone to
seal it and hold it in place.
