    I found these pictures of a homemade jig a while back and saved them because they looked like a good idea. No instructions but seem fairly self explanatery.

    Looks to be just made from plywood and 1 inch batten. I like the idea of the slider to get it really compressed. Ill be making something like it when I get some spare time.

    Hope it helps :)

    HDPE does not pour. It is like dealing with hot taffy. On the other forum is a really long thread on this.(HDPE sheet) It is a lot of reading but you will learn a lot on the subject.

    That will be fine. But you need to have a board or something that wont stick that will fit into the pan and some weight to put on it to make sure that there are no voids.

    Without being under pressure as it cools it can warp something terrible.

    Myself for my first HDPE attempt I simply used 2 foot long 2x4's screwed to a 1x6 board leaving 3 " between them. Which I found a board that fit, ended up with the whole thing in the vise under pressure.

    To mix you almost need 2 people, each with oven mitts, and tongs or something to grab the HDPE and twist as you pull so it becomes almost ropelike. Then coil it back nice and tight and reheat.

    Best of luck, plan ahead, try a small batch before doing a massive one, you will learn a lot.

    Taow may I say you my friend are a genius I was going to get a block of hdpe and cut my design out. I'm watching your video now and I'm doing this right when I get home how many milk cartons did it take to make the first piece
