Thanks,
I using an old german scrollsaw, the speed range is 750 upto 1500 RPM so i tried all the range, with 15T and 18T blades.
When scolling slow the acrylic become broken, in faster speed the material melt..
Maybe I will try to cut with sharp paper knife?

Hey there, What shapes are you cutting, some times it's less frustrating to use a coping saw to rough out and sand to shape. Takes a bit of time but no cracks.

Best to buy some lexan sheet.Can cut the thin stuff with tin snips if need be.Or your scrolly.Wont crack or shatter.Good to work with

Seems to me, that you might be better of using some polyester/mylar(?) transparancy sheet. The type that is used for the old style office overhead projectors, comes in letter/A4 size. It's fairly stiff, but can be accurately scissor cut.

I cut thin acrylic on my scroll saw.... even CDs!!!!!
All you have to do to stop the cut from melting back together it put tape on the top and bottom..... it lubricates the blade!
Good luck

I can't take credit for this "invention" ..... I don't even remember when/where I read about it, but it's well known among scrollers.
Using tape also helps avoid burning of hard woods like redgum. Only draw back is if you use clear tape and leave it on too long it's a bugger to get off.
Also.... when you put clear over your pattern often you get sawdust between the pattern and the tape making it impossible to see the lines... I find it much better to put masking tape on the wood, then use glue stick to put the pattern on ...... if the wood is very hard I stick tape to the bottom too.

Thanks All!
Just now tried Juvy's tip, so my problem solved,
Cutting 1 mm was succseful!,
Now I will pick some pieces of 3 mm and will try same way, but slower...
Thanks again!
