My grandpa had some tool called a transcriber, some pretty crazy looking knife. Basically you just run it along a straight edge down your plastic like 10 or so times depending on thickness, and it slowly etches a groove into it. After that you snap it, breaks clean. You can also use a fine tooth saw or a table saw I think.

For application you could either countersink screws or use a strong adhesive caulking.

I think that you can cut it with a regular wood circular saw, check the paragraph on usplastics

i agree that a table saw would be best but they can get kinda pricy. if u can make a good jig just save som $$ and get a cricular saw.

You could but it would take a long time and be hard to do a good job.

no it can be cut just like wood. The teeth on a medal saw are too small and it would take forever.

you get countersink drill bits and it looks like normal drill bit but at the end where u put the bit to the drill there is like a circular thing and it drills a groove sort of and ur screw fits in it so it doesnt catches when u grind and yes u have to drill deeper but not all the way through

this will work but it is sold by the foot. They arent selling anything less than half an inch think and obvioulsy the thick stuff is gonna cost way more.

You can do it without a countersink if you dont feel like getting one. Just a get a bigger drill bit and only go in a little bit. You just need to make a little hole for the head of the screw to fit in.

u can countersink a hole by first makin it the desired size so the screw will fit in, then taking a bigger bit (one about the size of the head of your screw) and drilling a larger, but not as deep hole ontop of the original

this should explain it

good idea but there is no need for using a larger bit for drilling a bigger hole, there's acthual countersink drill bits you can get to do that job but that's if you don't have the bit then you can use his idea
