Yeah I see that article then I see stuff saying it works. What I really need first is something to grind up the stuff bottles and stuff. Then I could make blocks I could mill. I have tried melting some bottles a couple of times and it is hard to chop up by hand. I used a paper shredder on milk jugs and it worked a little but didn’t totally chop the stuff up.
I think to do it right you some the style of this ssi industrial type units. I have seen designs for those but they require getting steel parts cut which would cost more than I want to spend.
