Blade change for Bosch 10" SCMS

[b4man]

Sometime in the past month I remember reading about blade warp and alignment on a CMS. I did a search but couldn't find the thread. However I saw that DL has the same saw as I do. My questions are; best blade, best way to insure accurate blade position and any other tune up advice.
I can set the correct line for a cut but the run out is way off.:BangHead:

How is your cut off, not square, plumb etc.?? I just bought a Freud Avanti(sp?) thin kerf 80 ATB cross cut blade for my CMS to replace the stock and dull Dewalt balde. It is a nice blade and a good price (around $40 IIRC)

I guess the best answer is it's not square. Let me try and explain what happens... when I set the compound 45 and cut it seems that the back side of the angle is fatter than the front where my line is. Does that make any sense?

 

[DaveO]

That sounds like either 2 things. Blade deflection, the blade bending slightly. Or the wood moving slightly as the cut is being made. I have a real problem with the later. If you can clamp the piece to the saw, you might get a better cut. For deflection, slower "feed" rate and/or a sharper blade will help.

Thanks Dave, this is why I figured a new blade was in order but the other advice will be taken!

Barbara, I am still running the blade that came with my Bosch and have not noticed any issues with deflection. I have had issues with the wood creeping some during a cut if I am not careful. Like Dave mentioned, if you can clamp your work piece down that will normally prevent it.
