Wondering if anyone can help me as this is doing my head in. When my saw is set at a 90 degrees cut, it cuts perfectly square and straight up n down. However, if I'm doing a 45 degree cut, it won't make the cut straight down. (always seems to be a few degrees off vertical). I've checked that the back fence is 90 deg to the table and all parts of the machine are tightened correctly, yet it still cuts slightly off vertical with 45 deg cuts. Any suggestions please. Been doing a load of skirting recently and resorted to making a mitre box and cutting external mitres by hand.
Which Makita mitre saw. On my Makita there were two adjusting bolts on the slide rail body one for left, one for right angle,to enable you to adjust 45°bevel angle either way if it was out of true.
Wonder it the mount/bench whatever is attached to, is lifting at one end with the extra weight/leverage when tilted? Mr. HandyAndy - Really
Yeah got the same on my 'Evolution', didn't notice until cutting skirting and had to mess about with the screws...
Perhaps then, the base is slightly twisting when weight is at one side. Only takes a tad, I'm sure ? Only throwing ideas at ya. Mr. HandyAndy - Really
I expect it might be something like this: The blade is cutting off angle at 45 deg because it is not swivelling in a level position across the fence/base, and is sort of swooping down and coming back up. Which you won't notice at 90 deg. So the whole blade and motor is either set forward or back from level. If its possible to adjust this, then I expect it would only be one screw to adjust.
Due to illness, my Makita mitre saw had been sat on the workbench unused for several months. When I came to use it, it was cutting a few degrees out at 45 degrees, yet before illness it was cutting perfect,yet no one could tell me why it had suddenly gone out of true. A quick tweak of the adjusting screw sorted the problem.
