Hi David,
I'm afraid I won't be home in time for that session. I'll think about it some more, though. Do you have a rough list of the large things that have to be inside, e.g. does the furnace have to be inside or is there a way to keep it separate?
Greetings, Martin

Hi Maybe you can join today 6pm UTC on our Mumble server murmur.libresilicon.com and we can discuss where to best place the airlock and how to build it the easiest and cheapest way?
Cheers -lev

Hi David,
some ideas / questions:
I was thinking about using sheet metal for everything
Pardon my ignorance, but how are you going to see what you are doing in there? Did you mean that one side is still acrylic? Front or top?
airlock
If this is on the side wall, then it is probably hard to reach with your hands. On the other hand, the back wall (opposite of the gloves) is the most precious space you have and "wasting" it for the airlock is not good either...
A quick idea would be to attach the airlock at the bottom, with the outer door facing towards you and the inner door being a "trap door" in the bottom of the box.
tools
If everything happens inside the box, space is even more precious. You'll need storage for the materials and chemicals, illumination stage, hot plate, spin coater, furnace, ... A rotating shelf on the back side might
be
a solution for that.
OTOH, an unsolved problem is be what the residual heat of the furnace is going to do to the acrylic box...
gloves
Gloves always bring the danger of trapping hazardous chemicals *inside*, right next to your hands. You'll probably need a material that withstands *all* of those chemicals, otherwise you might have the piranha etch make the gloves porous and then HF leak through them... A simple warning not
to
spill anything over the gloves is probably not enough because these
things
just happen anyway.
Greetings, Martin

Hi I was thinking about using sheet metal for everything which doesn't
need
to be transparent (even cheaper than acrylic glas). For the airlock I was figuring I could do a cut out like in the
attached
screen and fold it, then either weld or screw an aluminum box made from folded sheet metal as well.
What do you think?
