Which router bits and saw blades for acrylic sheet?

There are several ways to cut acrylic, but regardless of which method you use, you will want to prevent your cutting tools from becoming a source of damaging heat.*
Use a table saw, preferably with a carbide-type blade with 10 teeth per inch.*

Choose a saw blade that is designed for cutting acrylic. *
The blade’s teeth should be fine, of the same height, evenly spaced, with little or no set.* Be sure to feed the acrylic into the saw blade at a steady rate — feeding it too fast or too slow can cause the edge of the material to melt.
Thin pieces of acrylic (1/8″ or less in thickness) can be scored like glass using a scribing knife, metal scriber, awl or utility knife, and snapped apart.

Note:
This process does not work well for long cuts and may not leave an edge that is flat enough for capillary gluing...

Regarding saw blades...

I'm very tempted to make the cuts with the Diablo 40 tooth blade in my saw (this blade).
I've done enough reading and youtubing to know that the perfect blade would have more teeth like this one.
And I wonder if the difference is worth $50. All opinions welcome.

the 40T blade is a poor choice...
it will chatter and ''grab'' your plastic...
you need to remember that acrylic is nick sensitive and the nicks will cause/lead to cracking/splitting under tension/compression....

how about polycarbonate instead of acrylic???

As much as I appreciate the need/want to make your own I looked at this once myself and having replaced my Sawstop fence with an Incra I remembered that I already had the lens I needed on the unused fence. See if this part fits your needs and maybe save some money for other tools/blades/bits you need. Here's a picture of it as well and for $7 plus shipping maybe a good deal. If you need dimensions let me know and I'll measure it for you. I used this on my monster table saw sled for the very same reason.

Forgot the picture.........
