As i woke up this morning thinking about circular saw blades for laminated sheet goods
it occurred to me that a zero clearance insert similar to a table saw would fix the tear out!
then i googled and found this

its kinda complicated though. So i wont be using that.. I will be using the table saw method of attaching a plate and raising (in this case lowering) the blade
Re: zero clearance insert for circular saw
I'm not so sure a ZCI would solve tearout Bee. I was just reading last week that the very high end table saws have a scoring blade in front of the main blade to solve tearout. The scoring blade rotates in the opposite direction as the main blade and digs a shallow groove so when the workpiece gets to the main blade the bottom layer is already cut.

... you're sick man ... as sick as me.
Re: zero clearance insert for circular saw
hahahahaha bordering on obsession
Coz i noticed in my CS guide rail the side where there is plywood has almost zero tear out
Re: zero clearance insert for circular saw
I think this would be fine as long as you have a rail that will guide your CS along the cut line because not having an acrylic window will blind you of the cutting process.
For the pre-cut scoring, you may just score the cut line first with a heavy duty cutter before hand to minimize tear-out at the least.
Re: zero clearance insert for circular saw
ah yes, i have seen people do that with a cutter.
I will play with an zci design since i have 3mm acrylic scraps right now. And finally i have a guard for my crosscut ts sled 🙂
