Hi, I'm sorry, I couldn't find a good place to post this really.
I want to make some plastic covers, which should be pretty easy, but I'm not really sure how to get good straight edges.
I cut the plastic from a large 4'x8' sheet with a jigsaw so none of the sides are really anything close to straight. I have a mill that I will use to cut the plastic covers to size and drill holes in, but I'm stuck on how to start this.
Since none of the sides are straight to begin with, then I don't have a decent reference point to place the plastic in my vise and square the first edge. It's only about 1/8" thk so its pretty flexible.
Any help on this is much appreciated.
Thank you,
Aucran
