I have a Craftsman Circular Saw, Mdl. 320-10854, that I purchased several years ago. I have always had a problem when attempting to cut a square panel when holding this saw’s baseplate against a straightedge – the far end of the cut would always be approximately 1/8” outside of the drawn line. Today it happened again and I did some checking. I found that the blade (tested two different blades) is not parallel to the edge of the baseplate. I have been the only user of this saw and it has never been dropped or otherwise damaged and there is no damage to the edges of the baseplate.
Measured with a digital caliper, the left edge of the baseplate is 5.116 inches from the saw blade at the rear of the blade and 5.040 inches at the front. To obtain this measurement, I marked a tooth on the blade, measured to the marked tooth at the rear of the blade, just to the inside of the tooth gullet, rotated the blade so the same tooth was towards the front and measured at that point. I repeated these tests with another blade and obtained similar results.
I removed the blade to ensure nothing was under the blade causing it to be misaligned and could find nothing out of the ordinary with the blade mounting.
I can find no adjustment points to align the baseplate relative to the blade assembly. The baseplate is attached to the motor assembly with flathead screws in countersunk holes so there isn’t much/any wiggle room there.
Anyone have any suggestions other than getting a new saw?
