I'm no expert, but most tablesaw crosscut/panel blades have 80 teeth.

Gags, put a sacrificial backing of scrap behind your piece, then the breakout happens in the scrap!

jisk i was thinking the same thing

i tried the backing still didnt work. i think i will try an 80tooth and see how it goes

Try cleaning any resin off the saw blade - it can make the cut untidy, especially of the blade is a bit blunt.

Sharp blade, sloow cuts, the more tooth the better.
Last but not least, if your blade is not centered or a bit warped, or if your wood does not travel at 90 degree, you will also get tear out.

hey guys thanks for the replies! the blade that i was using is only bout 2 months old and hasnt done to much work! and it still real sharp! all thought perhaps my jig isnt quite square t the blade hmmmm ill check that! today i went and got a 60 tooth blade it was the balde with the most teeth they had in stock! i gave it a bit of a burl today it seemed a bit better but still not perfect

Did you clamp the backing scrap to your pieces... if you didn't its the only way you can get tearout using a backing!

Generally speaking:

16-40 toothers are for ripping
60+ toothers are for cross-cutting and "particle boards."
40-60 toothers are a combination that saves you from constantly swapping blades, but does neither job particularly well.

IMHO any well set up shop will have a couple of each type of blade and swaps around as needed.

For what you're doing I'd be looking at an 80 tooth thin kerf blade. And still use a sacrificial piece.

Iam seeing a lot of new people on this forum asking sometimes very basic Q. then getting all sorts of answers some of them very wacky.
On the left side of all threads there is details of who replied take a look at the number of posts they have done.These folk have been around for awhile and DO KNOW what theyre talking about. Sorry for getting blunt but when you were in school who gave the best knowledge to improve you, your dopy mates or the teacher, they have been there done that For gawds sake
