???? You might need to raise it up so it doesn't cut the square edge in the middle....then another round over on top.
Most trim is made with a moulder, and custom knives are made for the profile. Your profile is a common one, at least very similar to it. I just coped out some orepac trim very similar, but not the same....if it isn't going into the same room or you can move some trim around not to have to cope and and match up, you'd be better off buying something similar and hardly anyone will notice the difference. jmo, running lots of trim can be time consuming, especially with the larger bits where multiple passes are involved....and if you only need 16' or so, you'll be money (and time) ahead just buying it.
