<p>When working with plywood, I set the stop collar on the bit about 1/16" shy of the mark because plywood thickness is usually about 1/32" shy of the stated dimension, e.g.: 3/4" plywood is actually 23/32" thick. I'd still use the 1-1/4" coarse screws, even though I will usually glue the joint, also.</p>

<p>In addition to the above suggestions; if I'm building a project using 3/4" plywood, whether faced with a hardwood veneer or not, I use 1" screws, especially if the piece is readily visible, such as a tabletop. This provides an extra measure of safety against the screw accidentally poking through. I also glue all my joints, which would offset any loss of holding power caused by using the shorter screw.</p>
<p>Hope my two cents worth helps, Don</p>

<p>I'm a noob at the Kreg stuff myself, and will share my first experience with using it with plywood.</p>
<p>I had just received all my pocket hole stuff and just wanted to try it out. Grabbed a couple of scrap pieces of 3/4" construction grade plywood and attempted to join them into a simple right angle. Worked great except for one thing: Of the three 1 1/4" screws that I drove in, two were perfect. One poked through the opposite side just a tad. Pretty sure what happened was that the pokey…</p>

<p>I had just received all my pocket hole stuff and just wanted to try it out. Grabbed a couple of scrap pieces of 3/4" construction grade plywood and attempted to join them into a simple right angle. Worked great except for one thing: Of the three 1 1/4" screws that I drove in, two were perfect. One poked through the opposite side just a tad. Pretty sure what happened was that the pokey screw hit a void in one of the inner plies. You'll notice the gaps sometimes in end cuts. So, the screw compressed the wood more at that point, and kinda poked through.</p>

<p>It will work perfectly with 3/4 oak plywood. I built kitchen cabinets for my cottage using 3/4" maple plywood. Probably could have gotten away with lighter, but I know it's strong.</p>
<p>Use the coarse thread screws; even though the surface veneers are oak, usually the other layers will be a mix of softer woods. Kreg recommends screws 2" in from each end, and then roughly every 6".</p>

<p>1 More thing:</p>
<p>I would like to use a router to round off the edge once completed. How much leeway do I have before I get to the screw tip? Or should this not really be a problem?</p>
