fishnaked Posted February 8, 2022 Report Share Posted February 8, 2022 I'm building my home which has exposed 4x8 rafters throughout with tongue and groove decking over that. All exposed from inside. Where the rafters butt up against each other, I will be tying them together with Simpson 18" connector straps on top. I want to route grooves in the tops of these rafters so the Simpson straps will sit inside the grooves so the tongue and groove decking lays down nice and flat to the rafters. The grooves would only be 1/8" - 3/16" deep and 1.5" wide. I plan to set all the rafters in place then come back and make the grooves. Since they will be hidden, they do not need to be pretty. I just need an easy and quick way of cutting them while they are in place. I have a router with plunge base attachment...though I have never used the plunge. I don't have a straight bit which I assume is what I need but am not sure since a router is not a tool I use often. Which bit and technique do you all recommend?
