There was a question asked on reddit recently from someone that was trying to create a bevel on a door for as little money as possible which was accompanied by a lot of hate/negative feedback.
After watching this carpenter use a 3 Deg. router bit to make a bevel here: https://www.youtube.com/watch?v=nUNRI-UpSvw
It seems this could be a perfectly acceptable way to make a quick bevel in a tight spot. After I did a bit more digging around I found a bit that looks exactly like the one the content creator used in the video above.
Carbide Tipped Patternmakers 3 Deg x 3/4 Dia x 2-1/8 x 1/2" Shank.
Essentially this bit can handle any door up to 2 and 1/8 inches. I decided to do a bit more digging around and actually called the company that designed this router bit to ask what they thought about using this to create the 3 deg bevel for a door. They told me the only thing that would really be required would to place a piece of wood under the door. So that the wheel can spin on that instead of spinning on the actual side of the door to get the full 3 degrees required.
Can anyone think of a reason why this is not an acceptable method to create a 3 degree bevel for a door allowing it to swing freely into its frame?
