Hey Mo, that sounds like an interesting job! I don't if it is something in the water these days, or what, but the last three projects I have been involved with features octagons as part of their design.

WTF? I see the damned things in my sleep...

If you weren't joking about the Fein tool, and I assume that you must be, then you need to go buy one of those things right now! You won't know what you did without it. And don't buy the cheap knockoff brands either; the Fein is so expensive because it is bullet proof and awesome.

HI Mike, nice to see you here! Yes, what you drew is exactly how we are cutting the jack rafters. Another nice thing about doing it this way is the cut across the rafters (3 1/2 x 8) is one slice with the Bigfoot. When you say undercutting the valleys, I assume you are referring to cutting in backing cuts, because we are for sure doing that, too.

Thanks for the interest!
