Default Roundover bit advice

Hi: I've got to say this is one of the reasons I love the web.
I need some helpful advice about portable routing and BINGO!
A site and forum devoted to routers! Gotta love it and thanks
all for the venue and hopefully a little wisdom!


Have a small, portable router with a 1/4 inch shank.
I used it once a couple years back to trim all the laminate
I put on a cabinet I had built to hold recording gear. It worked
great and I was amazed that I even did it because it came out so well.

NOW...I just purchased a 2' x 6' butcher block surface that's 1 1/2 inches thick.
I need to round one of the long sides because I'll be using it as a recording-desk of sorts.

AT FIRST...I figured I'd get a 3/4 inch round over bit but I don't
think a 1/4 inch shaft is strong enough...nor my little router for that matter.

Should I just get a 1/2 inch bit? I guess I'm also going to have to
pick up some C-Clamps for a template guide. (Any thoughts here appreciated too)

've never worked with a round over bit and will probably practice on scrap first.
Not sure how to start the cut. ALSO...thought I read somewhere that I should
move the router in an opposite direction of the way it spins???

ANY AND ALL HELP VERY MUCH APPRECIATED! I suppose if it's too difficult to
do I could always try to find a small woodshop and have them put it on their table...but that takes all the fun out of it. Thanks, Bob

If you're just looking to ease the edge to make it comfortable to work at, a 3/8 inch roundover bit would work fine.

Roundover bits are bearing guided, so you can get by without using a template guide. You can use an edge guide, either store bought or shop made, to keep the router from tipping. A shop made offset sub base also works well for this.

You could also put an oversize bearing on your roundover bit so it takes a smaller bite on the first pass, or start with a smaller roundover bit and work up to your final size.

The feed direction on the router is always feeding the wood into the 'flat' face of the carbide. There are a ton of threads on the forum with examples of this if the small pictures dont suffice.

Good luck with the project!
