Please Help - How to Find the Router Bit w/the Correct Reveal
I'm newly learning, working on some of my own projects for my house. I picked up some trim from a local retailer and fell in love with the reveal, but alas, they cannot source additional pieces and cannot even assist in locating what the design is (for alternate sourcing). So, I have in mind to simply cut my own, but I am having difficulty (having never entered this particular world of art before now) determining the correct bit to achieve the same reveal.
Are there any recommendations? Tricks? Sites that I could upload an image/drawing that help match?
Any help is greatly appreciated.
