4410L Issues

notillegal

Looking for some advice from fellow bosch owners or a tool shop guy. I couldnt get the blade on my scms square to the table on both sides of the blade. I figured that was it for my saw so I purchased a new one. New saw same result, square the blade to the saw table on the left using the zero bevel adjustment, move square around to the right side of the blade and it's out of whack, did I get a bad saw or is this common ? Should I return it and keep trying till I get a flat table or what?

I don't know that saw, but
have you checked this out?

My 4410l did the same thing. To fix it I tightened the sqaure side of the fence down and loosened the wacky side. Then, with a clamp, I pulled the goofy side square and tightened it.

You should try an auxiliary fence made out of scrap baltic ply (what I use). The Bosch has screw holes along the fence for fastening. You can fine tune it with paper shims.

Legal,
There could be any number of things causing your readings.

1) Your square may not be square.

2) Your square may be a square square but it is sitting on the table (bed) out of parallel with the fence, and leaning ever so slightly out of square in the plane perpendicular to that of the square itself.

3) Your miter angle may not be exactly dead nuts square, and your square may not be exactly perpendicular to the bed in both planes, or exactly parallel to the fence.



Or: The bed is shaped like a "V" or an upside down "V".

The latter should be easy to check either by eyeballing or with a good straight edge. That, or bed twist, are the only things that can cause such a problem if all the above conditions are met with your measuring devices. Bed twist can be caused by screwing or bolting the saw to a twisted stand or bench.

You really need to set a stick with perfectly straight and parallel edges against the fence, butt the flat edge of the body of your square to it, and use a smaller square off the bed onto the flat of the tongue of the first square to insure it is square to the bed in that plane too.

Done that way, even if there is a slight misalignment in miter angle, you will be able to square the bevel angle accurately. That is presuming a bed that is in the same plane (ie. flat).

PS: Do not rotate the blade when checking from each side.

Cheers,
Jim
