trying to install a kitchen countertop. it is old house and corner is not squared so had to move cabinets away from wall to get L-shape to fit and now if put premiter cut counter top in there is large gap to wall. how do we figure the angle to be able to get the countertop to slide back further against the wall then
thanks so much in advance

Wrong forum, but here goes.....I assume a post formed top from big box??? It is almost impossible for a casual DIY to get a proper miter cut, but one not 90deg is even harder. Takes big equipment. There is no such thing as a square or flat wall in a house, does not exist. Tops usually have a backsplash that have extra material for scribing to the wall. That solves some of the problems. And there is caulk to match most laminate top materials.

Your description of the problem sounds like the angle is less than 90 degrees. Measure the angle and divide by 2 to get the correct mitre angle. When you measure, place 2 straight pieces of wood 3 or 4 ft long on the wall and measure the angle formed. The angle in the immediate corner may be built up and not reflect the true angle of the walls. Hope this makes sense. If you cut the mitre, cut from the under side with a circular saw. Use a straight edge to guide the saw. As stated above, an accurate cut is best made with specialized equipment found at counter top shops. Good luck with your project.

Yeah, I'm not sure that changing the miter is within the capabilities of a DIY'er.
If the cabinets have been pulled away from the wall, scribing or shoving the countertop tight into the corner would reduce the amount of overhang in front, wouldn't it???
I think a better solution would be to install the countertop as tight as you can get it to the wall, then if there is a gap above the backsplash, add plaster or durabond joint compound to the wall, to make the corner appear just as square as the countertop is.
If scribing the back edge of the backsplash is too tough, another trick is to actually cut a slot in the drywall and recess the backsplash back into the wall. But this exaggerates the crookedness of the corner.
Belt sanders w/36 grit paper come in very handy for scribing items like this.
