Roundover bit on non-square edge

[DrChek]

I have an edge that I'd like to round over. The problem is that router roundover bits are made for square (90 degree) edges. In this case my edge is more like 110 degrees. Any way to make a nice consistent roundover on a non-square edge?

Like this:

you can just use a standard bit and just make sure that it's high enough that you don't gouge the top surface.  Then just run some sandpaper along it to blend it in. 

Try it out on a piece of scrap and see if you like the result.

The only way I've come up with is to roundover the edge before making the joint on the 2 pieces of wood.  Then use a table saw to put your 20 degree cut on the bottom side of the wood leaving you with 70 degrees of your previous roundover.  Then join the bottom piece of wood flush.

Either you have to do the math or you have to start with the roundover and angle cut, then cut the depth of your top piece measuring for the new slightly shorter end of the board.

I don't know how long this edge is, but can you sand it round? I've been able to get good results with a power sander on shorter edges.

I wound up doing this and it worked just fine.

Glad I could help.

For future reference, You could also use a block plane or moulding plane,  and then sand.
