Summary: This saw out of the box WILL NOT CUT A 2X6 AT 90 DEGREES NOR BEVEL A 2X6 AT 90 DEGREES. With some filing of the right hand fence top I could get the saw to lower itself and cut a 2x6 at 90 degrees by 90 degrees. Beveling at 45 degrees by 90 degrees was impossible. The blade gruard, nut etc. prevents the blade from penetrating all the way through the wood. Otherwise it is a light weight and durable machine.
Summary: Let me make this short: this is all the miter saw 95% of us need. You can buy bigger, fancier more powerful saws with advanced features but this is all you really need unless you're a full time Pro who does trim and molding etc. all day long. It has a liitle "kick" at start up but when you make the cut it is so quick and so clean you forget it. In fact....I LIKE that little start up boost!
Summary: Being a finish carpenter for over 30 years I can say that this saw is excellent for the budget end of the Makita line...for the price it is very much worth it. The saw cuts accurately and is light in weight for portability.
Summary: You'd think it would be easy to find a miter saw that cut straights, angles, and bevels accurately (without having to adjust them every time), but alas no. I went through a couple of cheaper brands hoping to save a few bucks... live and learn. This saw doesn't have all the bells and whistles of some other brands, but it cuts true.
Summary: I have run this saw for four years. It is the old standby in my shop. It is fairly rugged for on site work as well and transports easily due to its light weight construction. The trigger safety on my saw is broken however. It is one of those small plastic parts that is easily cracked when throw in the back of a pickup at the end of the day. If I had to change anything about this saw I would have made that little button out of some type of strong alloy.
Summary: The tolerances of the Makita LS1040 are so tight that wafer thin pieces of wood can be shaved off and you can see through them. I am not lying. I shaved off pieces of 2x material and could see light through them. Also miter cuts in moldings are crisp and clean. I especially like tools with blade brakes because they are safer and blade changing is faster. Because of its light weight I have no problem transporting this saw from job to job.
