Thanks for your wonderful worklog.
i've been trying to make a dock and have reached a problem. i used a drimill to cut the holes and vent but when i went to cut the piece from the sheet of plexy, using a jigsaw , the heat from the saw would melt the piece back together as i was cutting. i finally got the right side to seperate by pressing down on the piece while sawing, causeing a serperation but as you can see that didn't work to well.
Also, what are the outer dimminsions that you used, meaing from edge to edge on each piece?
