Many years ago I worked for the western Australian Agricultural Dept in the experimental work shops building experimental farm equipment.We used to use acrylic plastic to make the machines weather tight .The first time I drilled a hole to put a bolt in the old fella who was the foreman pulled me up and showed me a trick that stops the plastic from splitting.. He lit the oxy and with a small flame applied it to the hole barely touching it at all ,the heat applied was just enough to melt the sharp edge of the hole .It produced a rounded edge and also got rid of the drill marks in the hole.The same can be done on a cut edge.It take a bit of practice but it works well .Just thought I would put it out there,but practice first . Cheers Ross
