I'm building some closet shelves using AC plywood, and I'm planning to paint both sides dark gray while leaving the edges with exposed wood. The AC plywood comes in two sizes: 1/2" and 23/32". I want to router the edges to create a rounded finish, like a half circle. However, I'm unsure whether to choose the 1/2" or 23/32" thickness for my shelving. Also, how do I figure out the right roundover radius based on the thickness of the wood? Lastly, should I route the edges before or after painting?

I agree with CraftyWoodworker88. You definitely shouldn't try to round over the plywood directly; it won't look great. Instead, glue on a solid wood piece on the edge and route that for a smooth finish. If you're aiming for a full 'half circle' effect, a 3/8" roundover bit is a solid choice. For a subtler curve, you could opt for a 1/4" or 1/8" bit depending on your style preferences.
Yeah, I think the hardwood edge is the way to go for better results. I've used roundover bits on better quality plywood like Baltic birch and got decent results, but HD plywood can be tricky!
This approach makes a lot of sense! I'm definitely thinking about using some white oak scraps I have. But, now that I'm considering the costs of the bits, I might also stick with something simpler for this project. Thanks!
