Topic tags/keywords: picture frames question shaping

Hello, I am new to LJ, just joined today. Being new to woodworking, this seems like a great place to learn, share ideas, get inspired, and learn more!

I hope this is the right forum for this…

I have a design for a picture frame that has a convex profile that I am trying to figure out how to achieve. I need to be able to duplicate this profile and it would be nice to have the pieces dimensioned properly at both ends so I don’t have to spend a huge amount of time sanding down so the mitered peices match up. Anyway, here is a rough idea of the profile

Now, I have looked and have not been able to find any roundover bits that large with an eliptical radius. The only solution that I can think of so far would be to make some sort of jig that my router would mount to and ride on a curved track, so the board lays flat, clamped in place, then the router passes over the board riding the track and cutting this profile a half inch at a time. This might be doable, but it might also take forever, especially with a 20×24” frame. Any suggestions would be greatly appreciated.

Short of using a shaper with a custom cutter or having a custom millwork shop make a profile and cut the wood for you, I can’t think of anything. The profile your trying to get is called a thumbnail or clamshell, but I can’t find any cutters available that large. You might even look at using solid wood clamshell moulding, instead of making your own.

Have your say...
