Thanks for your comments. This HDPE has been a very special gift this Christmas......to myself. Family members and friends are giving me their recycled bottles and I am having lots of fun showing others my latest bit of progress. It is so wonderful to have this kind of activity to get me away from work stress!!!
I have been reading the slingshot forum but not because I am interested in slingshots. They have a long thread about making HDPE which dwarfs what we have been talking about here. I had no idea there was that much interest in slingshots! There are oodles more slingshooters out there than top shooters, which I never could have imagined. If anyone is interested, here is a link to 33 pages of information about HDPE:
http://slingshotforum.com/topic/22723-hdpe-sheet/After reading some of this early one morning (when I couldn't sleep) I ran across the idea about making bowls with this stuff. I turned the oven on and soon I had some bowls to put some Christmas candy in. It got me to thinking about other possibilities.......like fans and frisbees and other toy possibilities.
I love the idea that I am slowly moving into the realm of toymaker. I always admired Don Olney.
