to cut acrylic with Freud 10 In. 30 Tooth Thin Kerf Glue Line Rip Saw Blade?
I've got a 10mm x 360mm x 360mm clear acrylic piece that I want to cut but have almost clear finished cut edge.
Could / should I use this blade to cut acrylic?
Would the blade leave a clear edge?
Thanks in Advance.Thanks,
Barry G. Sumpter

Not the best choice imo but with care it can be done and produce reasonable results. Better to use a recommended saw triple chip blade and the correct tooth geometry. 30 tooth is too coarse imho though. I use a CMT blade for aluminium and laminate. see

No and no. There are specific blades made for cutting plastics. In the absence of the correct blade plenty of teeth and negative rake would be the way to go. You would still need to polish the edge for an unmarked finish.

Figured out a super easy way to polish the edges so I don't have to be concerned with the rough cut.
Posted elsewhere on this site:
I got away with sanding 400 grit (up and back 10 times) then 800 grit (up and back 10 times) then polishing wheel up and back 5 to 10 times.
That flame technique was impossible for me.
Acrylic Edge Buffing to Clear
Used granat sandpaper
400 up and back 10 times
800 up and back 10 times
Polishing wheel up and down 5 times.
Wipe away residue.
If not perfectly clear polish again
At 30°c in the garage.

That is basically what I did making a couple of handles for a frameless window sash.
I actually cut about 4 pieces so I could experiment on them and just used two. Sticking the acrylic to glass is another story.

Just polishing took hours.
Flaming took too long and didn't really work like demonstrated.
More burning ans warping.
To glue acrylic to acrylic the edge needs to be rough. And use a type of superglue(?)
Were you successful gluing to glass?Thanks,

To attach the acrylic to glass I first cleaned the surfaces with acetone.
Next I used a high strength Araldite like this. Selleys 24ml Araldite Super Strength Epoxy Glue - Bunnings Australia
The important thing was to tape it into position and let the adhesive cure for a week.
Before going to the job, I tried sticking two pieces of acrylic together. I tried a silicone adhesive, and also araldite. After a few days the silicone still had movement, the araldite did not. Same after a week. While my test samples were small, and horizontal, the actual job was on a vertical plane and to glass. I was unable to stay on the site for a week, and the owners were actually going away for a few days. About two or three weeks later I contacted the owners and enquired how the handles were and they indicated all was good.
I used to do maintenance in a nursing home, where almost every window was frameless, double hung. We were forever trying to re-stick the acrylic handles back on the glass with mixed results. Of coarse trying to say do not use for a week would also have mixed results.
