Need Advice on how to cut acrylic sheets with circular saw

And definitely wear safety glasses. I don’t always wear them when doing lumber but acrylic will shatter like glass and throw shards a good distance. I have seen it routinely get thrown well over 20’ away.

We typically score and break acrylic (depending on the thickness) since it's quicker, easier and less mess and smell.

I know I am setting myself up for a few jokes lol, but I need help making cuts on 4x8 sheets of acrylic with a circular saw. I'm trying to cut a 2x8 board out of the 4x8 but i cant do it without the saw cracking the acrylic. What method do you guys use for cutting acrylic with a circular saw?

Take the blade off and turn it backwards. This is how I cut Vinyl siding for years before printing

reverse the blade in your saw

My words exactly....

this is the blade i picked up, you think this is a reason my board cracks? 7-1/4 in. 40T Finishing Circular Saw Blade

That blade is for WET LUMBER and doesn't have enough teeth to produce a smooth, chip free cut.

This is what I would use. The saw can chip and crack and break your sheet. The scoring knife is quick and easy. Probably takes the same amount of time.
