I know this has nothing to do with robotics and I’m not sure if I am posting this topic in the right place? I’m not and I’m having a little trouble navigating this forum. Anyway, I am in the midst of building a vacuform machine. I still need to make some final decisions on size, but I have the most of it worked out. Problem is, I am not much of an electrician, I don’t really know enough out it to say I can competently wire something together correctly without step-by step instructions. I’m veering away from what the usual standard vacuum source is. Most people rely on a tank to pull all the air out to create the vacuum combined with the use of a vacuum pump. I need to consolidate my use of space and a tank will take up too much space. So, I am going to use (once I decide which to purchase) an industrial vacuum motor with a high CFPM capability. Something in the neighborhood of 130-150 CFPM (or higher). Wiring it… I’m hoping it isn’t too difficult? I need to be able to wire it to an on/off switch. A foot switch would be great, but I’m not sure I can do that? And of course, have it wired for a standard 11v-12v outlet for power. That’s the primary vacuum source with a vacuum pump as a secondary source to get as close to 29hg (optimum vacuum) as possible. The rest is kind of logistically challenging which I can hopefully work out net working with people I know. The real problem is designing and building the oven. I flat out am stumped doing that. I need the oven to have a wide range of adjustable temperatures ranging between 150 deg. F upward of 450 deg. F to be able to set and adjust forming temperatures for a range of different plastics. I’m also hoping that the oven can be used for duel use such as pre-drying harder to form plastics like acrylic and polycarbonate or curing certain resins. Anyway, what I really need help on is being able to make the right choice in purchasing the heating elements I need to be able to hopefully do these things and be able to wire all of this together, so it’s done right, and it works consistently. If there’s anyone willing to get me pointed in the right direction and get me on track, that would be extremely helpful and much appreciated.
