Need help with some post notching ideas here. I am building about a half mile of post and rail fence. I'm using 6" treated round posts and 2x6 rails. I need to notch the round posts 1 1/2" deep x 5 1/2" to fit the 2x6 rails. I've done the whole multiple cut thing with the circular saw and then knocked it out with a hammer, but at 42 my back does not like that at all. Keep in mind each post has to have four notches in it for the rails. I tried a chainsaw, which made short work of notching the wood out but because I don't make a habit of carving bear statues on the weekends I found this very difficult to control. I have a good many of the posts already in the ground, so what ever I come up with needs to work for that. I thought of a planer, but I've never seen a handheld that cuts an 1 1/2 deep, and the footplate wont allow you to follow the cut down. If anyone has come across a similar problem in the past and has come up with a good practical solution for this I would appreciate your input.
Thanks
