Great video. Like the detail about the cutting angle. going to run my circular saw guide in reverse direction.

Jon, I tried the 7 1/4" Irwin #21830 circular saw blade (120 tooth) intended for cutting vinyl siding in my 10" table saw to cut 1/8" thick acrylic. It worked like a charm and made a nice crisp cut with no chipping. Thanks for the excellent advice and for the cost savings of using a $10 blade!

Be good to see a demo of the circular saw at work. A dedicated Diablo Acrylic Jigsaw blade is best for this when you need to cut curves. Making sure the sheet is flat and braced so it doesn't vibrate is super important. Lining the cut line with painter's blue masking tape will add extra protection for the surface of the acrylic from the foot of the saw. Spending $10 on a new sharp acrylic Jigsaw blade to cut a $50-$200 sheet of Acrylic is a good investment. Also newer oscillating work tools will cut thin acrylic well with a 3 quarter circle blade.

Wow - Great tips and visual aid on saw speed. THANK YOU. This guy knows his stuff!

Great and very clear advice from a real pro! Okay, before I saw this video I tried to make a long, straight cut on the 12" long side of a 36" piece of 1/4" plexiglass with my jig saw. Despite my best efforts at controlling the blade speed of the jig saw, it melted the plastic and wandered off my straight edge guide repeatedly. Nuts! Then I jumped on YouTube and looked for how to cut plexiglass with a circular saw blade, preferably with my DeWalt sliding miter saw. Thanks to Jon I'm heading over to Hope Depot to get the right blade and then I'll try again.

Thank you for the illustration on the blade speed. Something I've understood, but have had difficulty explaining to my friends. I will be telling them about this. Thank you.

That was a very awesome explanation of linear speed of cutting. Thank you so much!

I just cut 5mm matt black plexiglass to a precision rectangle with 5 perfect holes using a 10 watt diode laser. You gotta love how technology is moving so fast.

[elsf]

That was WAY more interesting than I expected! I just wanted to see why every piece I cut looked ridiculous 😄

[kirkwilliams]

Thanks for sharing your knowledge with us through this video.

Great Video. same advice applies to drilling holes with a hole saw, put your drill in reverse and get a cleaner cut

[RussellTHouse]

Mr. Eakes, I thought your point about linear tooth speed was very interesting...I had never before considered that. You further stated that using a smaller diameter blade on a larger saw would yield a better cut (I assume you meant for plexiglass). So if I were to mount a 6" plywood blade on a 7-1/4" saw AND reverse the blade, would that yield the best cut for that material?

I remember this guy on tv great to find him here 👍

[davivify]

Thanks for the informative video. Was hoping to see you actually cut the material. Next time?

[dokerbohm]

well shown well spoken well done video thanks for the advice

[bijan]

Hi. This was very educational. I want to see if I got it right. Are you saying I can insert circular saw blade into a table saw ? Please advise. Thanks. How about for making a circle?

[felixreali]

wow, this was actually very interesting to watch. thanks for sharing. great tips :)

[davidcurtis]

I've cut a lot of plastic and I usually just double stick the plastic or plexi to a scrap piece of wood and use the wood as a backer. I cut very small cuts and go through the plaxi in about 3 or 4 cuts and I get a fine cut with a normal table saw blade.

They make a tool just for cutting that stuff. I use it to make boat windshield.
