Miter Saw / November 3, 2018 / Evelin Nordin.
The GCM12SD in its perfect completeness also offers best in class dust collection at 90% dust efficiency when cutting 2x material with a vacuum attached to its integrated standard dual-purpose dust port. The new axial-glide design also expands the miter saws cutting capacity to 14" horizontally 6.5" vertically against the fence (base) and 6.5" when cutting crown against the fence (45 degree spring) for the most optimal usability. Additionally the saws etched stainless steel easy-to-read miter scale aligns with 10 adjustable miter detents allowing you to cut unique angles with accurate detents over the saws 52° left to 60° right miter range. Furthermore two 33.9° bevel stops are conveniently integrated and the saws high-visibility scale enables front bevel angle adjustments from 0 - 47° left or right. Situated conveniently at the front of the saw its push-button miter detent override additionally offers fractional adjustments for the most precise cut-lines.
All miter saws come with a left and right fence that connect in the middle of the saw. These standard fences are very accurate and great for perpendicular cutting. Because they are aluminum however they can bend or break relatively easily so remain cautious with your saw even when just making adjustments. Independent fences are also available for purchase. These are remarkably accurate and tend to yield pretty commendable results. Dust Bags: Because saw dust can be a problem with miter saws dust bags are essential for shop cleanliness and safety. They make a surprising difference in keeping your tools and parts clean but also save operators from inhaling airborne particulates. The dust bag connects directly to the miter saw and collects excess dust and debris during use.
A slightly more expensive and far better alternative is to use a metal track or tracks with a flip-up stop and measuring tape built in. Such a device is manufactured by Kreg Tools and is available in 4-foot track lengths that can be butted together to make longer lengths. My miter saw table requires four 4-foot tracks two for each side of the saw. The track is mounted to the top of the wooden fence you just made. You will have to adjust the height of the wooden fence (2 1/4"+ above the table top) so that the bottom of the flip-up stop clears the table by about 1/16" in the down position. The nice thing about the flip-up stop is that it can be flipped up out of the way without losing its measurement setting along the measuring tape.
I. Compound Miter Saws On a compound miter saw the blade moves in three general directions. First the blade moves up and down in a chopping motion. Second the blade moves about 45-degrees to the left and right for miter cuts and lastly the blade will lean either to the left or to the left and right to perform bevel and double bevel cuts. Although compound miter saws are typically more portable and less expensive than sliding compound miter saws they also have less capacity for wider boards. Most often a compound miter saw will be unable to through-cut a wide board with a single pass. II. Sliding Compound Miter Saws A sliding compound miter saw does all of the things a compound miter saw does while also adding a few more things to the pot.
