For a few years I have wanted to build a vacuum forming machine. There are many ideas I would like to cast in plastic. I see lots of potential in small areas, that places like China would not be hot on my heals to copy.
Here is the start of my machine, it is based on the Belovac design. You can see the video of the sort of machine I am copying HERE. (42 meg)
I managed to scrounge a vacuum pump for free from a friend. Holding my hand on the end of it, you can almost feel your blood been sucked through your skin.
I am using an auto LPG tank for the surge tank.
I am hoping to have this project finished withing two weeks.
How many cups will I accumulate by the end of the project?
I'll keep you posted.
