Crisp Cut In

I am trying to figure out what tool a person would use to create the deep cuts in the ends of a board. The cuts in the picture at the top of this thread are crisp and I cannot figure out how you could get them that way.

Why not a Dado?

Here are several ways:

a) Use a router and straight bit
b) Use a dado blade
c) Use three boards. shorter one in the center and longer ones glued onto the shorter one.

I'd use a daddo for the batch shown. However, if I were only to make one or two, I'd probably walk over to the scroll saw and use a #12 blade to make a clean polished cut.

I'd use a bandsaw, It's fast clean and easy - no set up time. I guess it's probably a boat builder thing but it's my go to tool for almost everything.

Looking closely at the picture, it looks like Charlese has the solution with his last suggestion (C.)...3 boards.

Are these frames for supers?

a (above) will work after something is done about the round corners formed by the router bit. Either chisel these out to make them square corners or round over the corners on the mating piece.

I would prefer the bandsaw solution.

Welcome to the forum. I would email the guy and ask him. Ross@myoldtools.com you might get lucky and he will answer back. Be sure to update your profile so we know where you are from. Check out the Shopsmith Map, and enter your location.

Hi Dusty! Even with a bandsaw, I would have to trim the cuts with a hand chisel to make them as perfect as the photo above.

BTW There would be no round corners if the board is vertical to the router bit. You must be thinking of having the board lying on it's face.

To make these cuts with a router, I would use a vertical push fence feeding it along a router table fence. One could also use an overarm router in horizontal mode and lift the table up so the workpiece goes past the spinning straight router bit.

Must confess the smoothest edges would be made by ripping off smaller widths from the outside of a wider (and longer) board - trimming the center part to proper length and gluing back the cutoffs. The cutoffs can now be trimmed to the proper length.

I gotta vote for a dado blade and the workpiece vertical using a mortising jig. But then I do not have a router table!
