Hi,
I recently bought a Bosch GCM12SD glide mitre saw to replace my Dewalt. I got rid of the Dewalt as it was nearly impossible to push the blade straight through material (front to back) without deflection. I could not get an accurate 90 degree miter, and repeated cuts were all slightly different.
I am having a similar problem on the Bosch. The miter detent lever is plastic and when (properly) engaged, it (or the mechanism that it is part of) can wobble a bit, therefore you can lock the miter at slightly different angles. Therefore if it wobbles a bit to the left, I don’t get a nice 90 degree cut. It is about 1/32” off at the end of a 12” deep board. Am I being too critical? Does anyone else notice this? If you can’t count on the repeatability of most basic of cuts, than that would seem to be a problem.
