Why Not Pull through a Sliding Miter Saw Cut?

My son these days requested me why I push my slide noticed (miter noticed), no longer throw it away. According to him, the manner the noticed blade rotates will preserve the board against the backrest and prevent the threshold of the board from bursting. What do you say? - Scott Elam

Tim Inman: Tomato or tomato? The noticed will reduce either way. That said, there are protection reasons for cutting by means of first extending the saw out of the "base of operations" after which turning it on and making the cut through balancing the noticed on the wood and pushing returned in the direction of the house or blade attachment location. . I suppose there may be additionally a quite right case for better overall performance doing it this way. 

One feasible point of bewilderment is that for my vintage nemesis, the radial arm noticed of the 1960s and Seventies, the "accurate" slicing series changed into to start the cut from the lower back (fence aspect) of the board and get rid of the carriage from the noticed. Through wood even as reducing. I don't like those saws for numerous motives. One of the principal motives is protection or the shortage of it. Remember, I taught high college children the way to use one's saws within beyond. I actually have first-hand enjoy, and from all my arms!

In milling or cutting, there may be a phenomenon known as "up-cut" or "up mill". These terms describe the impact of the cutter's teeth wanting to take large and larger bites of wood as they chew at the substrate in the query because of the way the reducing facet engages the wood. If this happens and it gets out of control (which can occur very quickly at times), the blade will move slowly uncontrollably up the wooden. 

If the device is not robust sufficient to withstand the pressure, the blade will climb thru the wood too speedy and can also climb over the wood without slicing it absolutely. This is scary and dangerous. I have "loved" this experience far too typically inside the school stores that I have taught not to feel the chills on every occasion this topic comes up. I never had an injury, but wow! 

Although the slicing route of the pressure vector from the blade tooth pushes the timber firmly lower back onto the rear guide, the opposite vector pushes the noticed with full chew force closer to the operator. 

With modern-day slide miter saws, which carry the noticed to the front edge of the board and make the cut when the noticed returns home, the sawtooth doesn't have any compromise to "climb" with the wooden. The phenomenon of escalation is defeated. The reduction is cleaner and the job is done plenty safer.

As for craftsmanship, while reducing efficaciously as defined for the miter saw, the blade passes the newly cut floor simplest as soon as. Cut completed, the saw finally ends up at the base of operations. Work is done. Cutting backward way that the noticed begins to cut out of the bottom role, then is pushed again past the just cut floor once more when engaged, until the noticed stops at the give up of the reduce. This, in my experience, never takes place. The result is a less smooth, fuzzy, and sometimes burnt area on the brand new cut.

So the short answer for "why" is "due to the fact". This is how I trained my children and the way my father educated me too. The longest solution is because it works higher and is tons more secure.
