Jon’s MIK build has me thinking and I wanted to pose this question 1) So I don’t try and reinvent the wheel and two see if my theory or thinking would work.
The question is: how does one make repeatable V grooves in a board (say plywood) so that it simulates the V groove in tongue and groove boards. I have always just scribed a line with something like the back of an exacto knife. But Jon set out to do it on a router for faster more repeatable and uniform cuts. And it got me thinking, is there a way with power tools to get the look. We have seen board and batten made this way with dado blades. Clapboard can be made with a dado blade set on an angle. But how to make a thin line and best a thin V groove?
My first thought is this should be easy with a table saw and a carbide tipped blade.
The bottom half of this picture shows the three most common tooth arraignments for carbide blades. And while I was thinking of the ATB arraignment (which is the most common) I think any of the three would work. If a person were to tilt the blade to 45 and then lower it down to the point where the blade only just nicks the wood it should, in theory, make a nice v groove as at this point only the tip of one corner of the blade should strike the wood and it should cut a V groove.
Am I thinking right? I am not at home to give this a try or I’d answer this myself. The curiosity is killing me.
