I am unsure as to what size of a roundover bit to use to give it a rounded finished edge. Am I correct in thinking a 3/4 " roundover will give it a full radius edge? Any help would be greatly appreciated.
What I am not understanding is how are the roundover bits measured. I would like half to three quarters the thickness of the pine rounded over,
Thanks in advance,
Karter

To do half the thickness rounded, you'd use a 3/8" bit - for three quarters of the thickness rounded you'd use a 1/2" bit if I'm understanding your question correctly - I'm assuming you want one flush edge. The roundover bits are measured by their roundover radius. So yes, a 3/4" roundover bit would round the whole edge of 3/4" thick stock into a quarter circle shape.

Thanks for the info, that is exactly what I was looking for. I do want a flush edge. I will use the 1/2" bit. Thanks again.

This is exactly the answer I was looking for to my thread . You said it clearly and precsicely . Thank you.

So, to make quarter round molding...?

So, if I understand this right, this is how I would mill quarter round molding? I'm new here too, and I'm trying to make my own quarter round from 3/4" thick bords. If I use a 3/4" roundover bit on the edges, then run it through the table saw at about 3/4", does that sound right?
Thanks!

Hi Chery

You would use a 1/2" Radius bit the norm for 3/4" thick stock.

see listing below what the round over bits will do..

Than once you put the profile on the stock rip off what you need.

If you use a 3/4" roundover bit on 3/4" stock, that will give the same profile as the 3/4" quarter round in Home Depot. You would have to use the fence on a table, though, as the bearing on a 3/4" roundover would not engage the edge of the stock. Using the ½" bit gives you a nice roundover and allows the bit to engage the stock, if you don't have a table.

I prefer to use wider baseboards and chuck the quarter-round entirely.

It depends on the actual profile you want. For a true circular profile, the radius of the bit should equal the thickness of the stock. If you want a bit of flatness on the side, a smaller radius would work.

G’day Cheryl

Welcome to the router forum.

Thank you for joining us

Thanks fellas!

I think I'll try both the 1/2" & 3/4" and see which I like better- I'm using a router table for sure- I don't think I'm good enough to try freehand on this! LOL

I've got large baseboards too, but I need quarter round in some rooms to hide the gap from the new flooring I installed. Old house, unique baseboards..wasn't about to try & remove them in one piece, so I just left them on.

I did make my own wide baseboards with the router for the new pine plank porch floor- that worked out well, so I though I'd try quarter round.
Thanks for the advice!
