<p><strong>Saw-cut depth setting</strong>:</p>
<p>Set the saw blade depth, so 1/2 of the teeth are showing, where the blade exits the work-piece.</p>
<p>This will result in the saw tooth "slicing" the top layer of plywood.</p>
<p>I most cases a 1/4" of the saw blade teeth will be showing, which is adequate to make a clean cut, when using the appropriate blade.</p>

<p>Use a utility knife---"score" a line into the top layer of the plywood---this is a slicing motion.</p>
<p></p>
<p>When cutting plywood, making the first pass using a score cut of 1/16-1/8", followed by a full-depth.</p>
<p>This will minimize chipping of the plywood.</p>
<p></p>
<p>When the saw tooth cuts in a UP and DOWN fashion thru the top layer, </p>
<p>splinters will occur.</p>
<p></p>
<p>When using a RAS (radial arm saw), for cutting thru the material, the saw blade is set 1/8-1/4" below the table surface.</p>
<p>On a RAS the saw blade is "downward" and on a table saw the blade it's "upward".</p>
<p>Therefore, set the sawblade 1/8 -1/4" above the surface of the work-piece, on a table saw.</p>
<p></p>
<p>NOTE: When ripping on a table saw, cutting boards or 2x stock, and when using a combination or rip blade, set the depth of cut so the gullet of the blade is showing. The deep gullets are designed to remove the sawdust rapidly. When ripping thicker stock, and the cut does not go all the way thru on one pass,</p>

<p>I've seen two philosophies on the depth setting:</p>
<p></p>
<p>* LOW SETTING: Set the depth to just beyond what's need to cut through in order to avoid tear out, etc. This - I believe - is generally considered safest approach.</p>
<p></p>
<p>* HIGH SETTING: Set the depth MUCH higher than what's needed. The theory being when the teeth come down into the plywood, they're cutting straight up or down. (It would be down on a table saw, up on a circular saw.) So the idea is that you get cleaner…</p>

<p>As far as surface to cut on, I've been using the Kreg Rip tool on my circular saw on boards clamped to a work table. I've not ripped full plywood sheets yet, but I actually need to this weekend. So I'm going to big box store and getting a 4'x8' solid foam insulation board as suggested above. It'll get hacked up, but will be useful for a whole lot of cuts first. (Seen some folks using this method on YouTube and it seems really great and safe since you get plenty of support and can just crawl across the board without having to lean far - and oddly - which maybe risks slipping.)</p> 2" thick (4x8ft) rigid insula…tag:kregjig.ning.com,2013-09-14:2900167:Comment:5696262013-09-14T14:53:47.067ZKen Dargahttps://kregjig.ning.com/profile/KenDarga

<p>The insulation board can be easily cut in half, making (2) 4x4ft sections.</p>
<p>Use one section for cutting smaller objects, and butt both sections together for larger sheets.</p>

I raise my skilsaw to the depth of the plywood with a few teeth showing. It will lower the chip out on the under side of the board, Ken. I found that out by trial and error when I sawed some plywood. I hope this helps you out, Scott.</p> Henry,

<p>Remember the old saying I've heard about novices and amateurs: The difference between a novice and an expert is that the an expert knows more ways to cover up their mistakes. Everyone starts somewhere. Dive in, have fun, learn as you go, and never be afraid to ask for help! As you can see, this is a great place to do so.</p>
