I need to make a few fairly repeatable and accurate cuts out of a 12" x 12" x 1/8" piece of ABS plastic.
I've tried sawing, scoring with exacto knife followed by breaking off, and of course sanding. The issue with these methods is 1) it's time consuming, but more importantly 2) the pieces aren't 'similar enough', they don't repeat within, say 1/8" (more or less may be sanded, oftentimes not exactly straight, etc).
So one idea I had was to use something like this:
I.e. one of those paper cutter tools. I don't mind if it takes a bit of elbow grease to get the cuts going, my main concern is that I'll get a long, straight-as-possible edge that I can repeat as consistently as possible about a dozen times.
Before I invest in something like this, what do you think, is this a good idea? Is there anything else you'd recommend for my problem? Thanks!
