    I'm creating a countertop surface for a cabinet that will sit on the floor, I have plywood, and I've maxed out my budget to buy any more lumber. I want the edge of the countertop to have a rounded edge so I was going to rout it with a roundover bit.

    I've heard some people say routing will cause the plywood to fray and instead I should glue a solid piece on the front and rout that instead.

    But I've also seen examples of plywood that seems to have been routed exactly this way and it looks fine. (Example 1, example 2.)

    What's the secret?

    It's the grade and quality of the plywood.

    Darn, I was worried that was it. I'm using cheapo stuff cut from a $15 4 x 8.

    Guess I'll be gluing a solid piece on the front...

    You can buy solid wooden moulding that's already rounded.
    It's called 1/2 round molding.

    dont waste your money on the cheap plywood because, in time the plies will begin to separate. the cheap stuffs glues are not resistant to moisture. If you look at your example #1, you will see that it is made from 9 plys glued together. it is probably A / B or C cabinet grade plywood

    It's also full of voids between the ply's forming weak spots.

    Now, what kind of DIYer would I be if I didn't make it myself?? Besides I have to justify the $50 router bit set I just bought as a birthday present to myself.

    Thanks guys, I'll keep that in mind next time. Although I'd add that I still have stuff I made out of cheap plywood years ago and I haven't experienced any problems from it.
