Here is a jig I just made to make it possible to route a piece of wood, such as a branch, that it too crooked to work on a regular router table.
This jig replaces the usual round baseplate on a router. It has 2 guides instead of just one that a router table would have. Both are adjusted the same distance from the router bit. No need to measure. Just use corresponding marks. You set your width for the widest part of the branch
When your branch gets narrower you twist it between the guides so it remains in close contact with both guides. It self-centres the routed part in the branch
Here is two halves of a crooked branch just routed. You can see the branch curves up and down and even has a twist but it routed with no problem.
