... and hopefully make a vacuum machine. The chamber comes first, though:
Vacuum puts a whole lot of stress on the materials and sealings, I am rather sceptical this will work - even for a test! What speaks for this particular setup is that the washing machine was such a heavy flokker that the containment barell (which this project uses as the chamber) had 1 mm thick steel instead of the 0,5 or 0,7 steel used in pots of the larger size. I think...
A great view into the chamber. When it is airtight (a rubber sealing is left to be fixed on both the lid and the rim of the chamber) and the hole in the bottom has been somehow fixed, I will get me some metal plumbing and hook it up to the old vacuum cleaner.
Silicone moulds will be better, but even better yet: The crappy casts I've made these six or seven years will now be replaced with something more professional, finally. As parting words I should add that this project is just a test - I have a small budget, but there's still left for better parts.
