I really like those symmetric/complementary shapes. Flip one piece and it can make for interesting joinery.

Are your curves for the hollow and roundover identical?

SplinterGroup... yes.. I made my Hollow and Round both 1/2" and identical. They're a matched set.  🙂

Love seeing the old ways to do things like that! Very cool..

Glad you like it RyanGi ! 👍

It's fun to create compound profiles from simpler shapes. Thanks for sharing your process with us!

You're welcome Steve. There are others I'm seriously thinking about making. A matched set of snipe bill moulding planes, a classic panel moulding plane, and another matched set of smaller Hollow and Round moulding planes likely 1/4" or smaller. 
I had no idea that I would get into moulding plane making but started and like the results. It opens up some intriguing possibilities in my woodworking. 🙂

Great description on the process, and the moldings created are first class. Nice work.

Thanks again Oldtool! Glad you appreciate it.
