<p>My router proved to make very smooth edges on the circular sections of a birch plywood project I was building. So much better than the straight cuts I made with a circular saw, with plywood blade, that I decided to even use the router to make the remaining straight cuts. I clamped a straight edge to the board as a guide...</p>

<p>From now on, the router is what I'll use the cut birch.</p>

<p>Hi....another direction for your consideration as most of the solutions have already been given. Since all my projects are constructed of birch ply being able to get 2 very good sides and more stable (additional plies). If you can, try to acquire real Russian Baltic Birch plywood 5 x 5 as it has a much thicker finishing layer than standard 4 x 8. We call this stuff Quebec Baltic Birch and avoid it unless being painted. The thicker venier stays in place and you can actually sand it</p>

<p>Stephanie,</p>
<p></p>
<p>All of the previous points are great. The other thing to consider is that not all birch plywood is created equal. I have had similar problems with imported birch plywood. You may pay a bit more for domestic but the veneer is usually better quality and it won't peel as easily. I've noticed the imported ply has gaps in the plys after cutting. A mdf hybrid core is an option because the ply will resist warping. Good job on your project.</p>

<p>I have experienced similar issues with my round over bit and plywood, and from what I can determine it happens when the cutting tool is 90 deg to the grain, of which has happened to your project.</p>
<p></p>
<p>A bit late now but you could possibly score the top surface with a sharp trimming knife (box cutter)</p>
<p></p>
<p>Otherwise use a spiral down cut router bit, Be warned its an expensive exercise if you do not have the gear already.</p>

<p>Hi,</p>
<p>when you cut plywood you can use:</p>
<p>1. masking tape (painting) for prevent "tear-out" for longitudinally cuts.</p>
<p>2. fine tooth blades, for example 96 and more tooth.</p>
<p>3. sander orbital machine and sander paper 180-200.</p>

Chevyguy65 is right. Preferably, 1) you need the right blade and, 2) if it's adjustable, a less aggressive stroke on your jigsaw, and 3) move slowly allowing the saw to do the work. Also, you might 4) cut with the good side up or 5) sandwich the piece between two thin panels to reduce tear out.<br />
<br />
I'm sure both you and your pet will really enjoy your stand. Good work!

<p>Interesting article! I had never heard of bloat and have had dogs all my life. I will say this is the very first time I have fed my dog in a raised bowl. Naturally, I want to do what's best for my pup, so I will research bloat further.</p>

<p>Re: the cut-out for the bowls</p>
<p></p>
<p>Use a 1/4" round-over bit, in a hand-held router, to smooth the saw-cut edges to make them smooth.</p>
<p>If needed, follow-up with 150-180grit sandpaper, as a follow-up, if needed.</p>
