You guys may want to consider your health a bit more when considering your building materials. Risking your health to save a couple hundred bucks is a bit silly if you ask me. For starters, acrylic, polycarbonate, and silicone should not be used anywhere near Butane, Iso, or Ethanol. Second, JB weld or other epoxies should not be used either. Basicallly when you are working with the three aforementioned solvents, you want building materials to all be made from stainless steel, aluminum, brass, glass/boro/pyrex, PTFE, Polypropylene, and a few other materials are ok. Here is a chemical compatibility chart to reference...

Another thing is storage, its terrible that silicone containers have become the most popular medium for concentrate storage. Silicone is not safe at all with the chemicals we use. Silicone and butane are a huge no no(very incompatible) so, any residual butane not purged from your concentrate will interact with the silicone and could be causing you harm. Ethanol is not very compatible with silicone either. Iso and silicone are ok though.
I wont even get into the dangers of untested/McGyvered vac chambers and drawing large amounts flammable gasses through a non-gas rated fan/pump. The only words I will add is SAFETY GLASSES AND FIRE EXTINGUISHERS PEOPLE.
Please people, we need to start being more careful with what materials we use. You are better off to just stick with flower if you can afford to purchase the right materials to make concentrates safely. Keep it safe guys and keep your health in mind
