I bought Makita 7” sliding miter saw to have a easily portable saw. Lugging a 75lb 12” was not doing it for me any more.

In any event today was the 1st time actually using it. I squared the blade using their plastic square and checking with a regular framing square. It is dead on at 90 and 45 deg.

I am cutting wood in a picture frame configuration. The lengths are approx 48”. Problem is the only way to get a tight 90 deg total corner is to set at 46 deg?

I am new to using such a small blade miter saw. I was thinking, does the larger the blade make the accuracy better? I am thinking when you are checking square you can get more accurate longer distance from the fence?

Take a board that is near the cutting capacity of the saw in width x say 18”+ long. With the saw set to 0° cutting near the center of the board make a cross cut. Now flip one of the pieces you just cut over, placing the side that was closest to you to the fence. Butt the back cut together and check for a gap. If there is no gap your saw is cutting true. If there is a gap, adjust saw until tight joint is achieved.

Bevel of saw could be slightly out. Or the miter of the table itself. Follow process above then use a metal square to zero out the saw.

Also. The longer the run of board on the fence the more it will show if its out. This is also true if you have a very short run. 1% in either way could be an actual 3% if you stick a .5 on the 1% and a flopped up bevel in the mix. (Note I used % rather than degree marks because I’m using a handheld kindle to type this). Try hanging crown mold for a project and you will file the degree notches off your saw … Lol
