Topic tags/keywords: router roundover

Hello. I am making bench seating for my kitchen (photo attached). You’ll notice the seat top which is made out of 3/4” MDF has an inside corder. My wife wants me to roundover the edges of the seat. I was planning on using a 1/2” roundover bit on a router table, but I don’t know how to stop the cut so that the roundover doesn’t either stop short and look noticeably different if I were to touch it up by hand, or worse, the roundover breaches the stop and effects the small seam in between the two seat parts.

Any ideas on how to stop a roundover?

Maybe I don’t understand the question. The seat panels are already installed, right ? Just take a hand held router and run it along the edge of the seat and when it gets to the corner it will stop, then you begin the adjoining seat.

I would recommend rounding off the outside corners of the seat, as well, if you hadn’t already considered that.

Mark the spot you want to stop. Mark it on the side you will see when you feed it by the router. Stop feeding when you get there (or swing the board into the bit and START feeding from there)—finish by hand with a file/sandpaper.

Would be smart to practice on scrap ‘til you get comfortable with the start/stop thing.

I agree with Yonak. Besides, handling large panels on a router table can be very awkward. Hard to do a super clean job.

But: if you really want to do it that way, rig up some kind of stop so the mdf can go only as far as you need it to. Could even be a block clamped on to the panel to stop it when it reaches the fence.

Of course if you were looking for a reason to add to your tool arsenal, you’re on your own there.

I’m beginning to think there’s something wrong with the software on this site. I’ve never been on a forum that has so many cock-id pictures.

Don’t use the router table. Use a hand held router after the seat is installed, it will be easier and less complicated.

You could always glue and tack some sort of molding to that front edge.

I’m with Yonak, scissors, and Bondo. Unless I’m missing something all you need is a roundover bit in a handheld router.

+1 for Yonaks suggestion on rounding off the corners too. That sharp corner on an MDF seat ain’t gonna last too long.

BTW, that bench looks great in that corner! I don’t know what your finishing plans are or how much you’ve worked with MDF but… If your painting it, seal the edges first otherwise you’re going to have a hard time getting a good finish. If your covering it with some sort of upholstery, don’t plan on being able to staple into the edges or near the edges. The center core won’t hold the staples and if you staple too close to the edge on the face, it’ll split and eventually pull out.

Round over bit in a handheld router done in place (or with the boards mocked up in the shop), the bearing guides you right through the corner.
