Hi – I could really use some help with miter saws. I have a 12″ Bosch compound miter saw and it is not cutting 90 deg bevels and the adjustment wont help. I have already replaced the fence once on this as it was not square. I am wondering if i should send it to have it fixed or get something else. It is stationary in my shop and i use it for finish carpentry/woodworking only. I am willing to spend $, but reallly want an accurate saw. Any advice appreciated. Thanks.

Dear Seamonkey,
Love the handle! I use 10" slide saws to make my living. (Sliding Compound Miter Saw) At full extension they all have some flew, including the Kapex. Personally, I use only Hitachi's. I know a lot of folks who like the Makita's. In order, I would rate them as follows:
1) Hitachi
2) Makita
3) Bosch
4) DeWalt (12")
5) Milwaukee
Best,
John

I have the Bosch 12" CMS, not the current model but maybe 3 years back. Have had no trouble with it maintaining accurate bevel setting (we are talking bevel, not miter, correct?). Does your's start accurate after tuning, and then slip? or is it impossible to set it correctly??
How do you check for accuracy? with an angle gauge/drafting square, or are you making the recommended test cuts afterwards??
Lastly, are you taking steps to insure that there is no, nada, absolutely zero slippage of the stock when you cut a bevel? (easier said than done)
Yep, its the bevel not the mitre (havent gotten to that yet). You probably know there is a screw that adjusts the bevel stop in the back, and i have it bottomed out. I have been checking this with an engineers square, not actual cuts. Maybe that's the easier/better way. I will do that tonight. Thanks for everyones replies.
I always use cuts, in the methods shown here, to test and tweak settings done with a square or drafting triangle. Just seems to bring the final setting close(r) to perfect.
I'll have to take a look at my saw, see how far that adjustment screw is setting. Bottoming out seems like not a good thing. Does make one suspicious.

seamonkey,
Just a thought but if memory serves me on some saws you need to follow setup instructions in order as subsequent settings rely on previous settings. Not sure if this applies in your case.

A Woodworkers mind should be the sharpest tool in the shop!
Take an air hose and a wire brush and REALLY blow out all the sawdust that has accumulated under and inside the miter saw. Pay particular attention by the adjusting screw stops. If you're trying to adjust against a build-up of pitch, sawdust and assorted other crud, you will not be able to get and keep it in proper allignment.
