I've got a train of thought "what is the better way to do this task and are both options asking for trouble?"
I need to cut a 3/4" wide dado that is 5/8" deep. Due to the state of ductwork and other tools, I want to do it on the table router (everything is a nail right now).
I have a half inch and 3/8 inch straight bit and I used the 3/8 to cut an initial dado. Now I'm concerned because it looks a little like a climb cut and I don't want this 6' piece of 2.5x2 to rocket off the router.
Assuming I can do the rest of the dado like this, is it better to widen the dado with the existing dado to the left of the bit or with the dado to the right of the bit? (From outside to the fence with an imaginary line intersecting the cut area the difference is Wood, gap, bit, wood, fence or wood, bit, gap, wood, fence)
Maybe I'm over paranoid but with two options, I'm torn over whether they're both safe or one is better than the other.
A rabbeting bit would be a better option, but I'd rather just use a straight flute that I already own.
So, does it matter and why? I think the gap to the right of the bit would reduce the chance of a climb cut, but if the piece comes off the fence and touches the bit, it could pick up some momentum from the bit. With the gap to the left of the bit, it seems like a climb cut (wood trapped between fence and bit).
