Router Bit For Cove Molding

[Ken Krawford]

I want to make some cove molding out of 3/4" x 3/4" stock. What size radius do I need to give me the correct profile?

I'm going to guess a 1/2" radius assuming you want about an 1/8" land at each end of the cove (https://www.lowes.com/pd/EverTrue-Craftsman-3-4-in-x-8-ft-Unfinished-Vinyl-Cove-Moulding/1000445423?cm_mmc=shp-_-c-_-prd-_-mlw-_-ggl-_-LIA_MLW_122_Mouldings-Specialty-Millwork-_-1000445423-_-0-_-0-_-0&ds_rl=1286981&gclid=CjwKCAjwqeWKBhBFEiwABo_XBjpJMacufAQuPL3upUog JSpuWkYeeOLSRjDzLGm8AneK6xDUOKb6ARoCXIcQAvD_BwE&gclsrc=aw.ds).
