Perhaps someone else has a better idea.
I have a cordless DeWalt circular saw. The intended use was as a cordless saw in general, and also as a trim saw.
When the saw was first acquired, several cuts were made of a 2x4, and the blade and angle index pointer were set to zero based upon measurement of the squareness of the 2x4 crosscuts. It turns out that this may have been a mistake.
Recently when using the same saw for trimwork, several cuts were not square, or at the needed 45 or 30 degree angle. Upon examination, and test cut, some test pieces were at the correct angle, and others were not. Some cuts were crosscuts and some were rips. Generally, the rips were off.
Upon further scrutiny, it was found that the shoe (base, sole or whatever it is correctly called) of the saw was not flat. It is a steel stamping, and is reasonably rigid, but bows up in the middle longitudinal portion of the shoe, and when thinner pieces are ripped, the angle shifts because of this.
To fix this, the thought is to remove the shoe, and incrementally press on the center of the sole, to bend it to a flat position. It will have to move a little less than a tenth of an inch (haven't taken the blade off to measure). A hydraulic press would be used, and the changes would be intended to be small, realizing that it will be necessary to push beyond flat, and then rely on inelastic deformation to provide the desired sole changing.
Has anyone done this? Is there a better way? One concern is that going though this process, particularly if there was an overbending (and stretching) and the shoe had to be bent back the other way, might result in a warp of the rest of the shoe.
We are not talking a high end saw here, with a cast magnesium, rather the shoe is made of a mile steel formed sheet steel.
Thanks again.
