Here is a good writeup for a 4 to 1.


With the way they go throught the steps for it, I'm sure you can figure out how to do your 2 to 1.

For the 3 to 1 you just use different angles for your cuts.

Here is a honda-tech thread about making jigs to do your cuts. There is also some discussion on the angles.
