What's the best way to mortise on my drill press?
It's been a while since I last checked into Wood Forum. I have started a new project building a sofa table and have some questions about the joinery. The legs and stretchers will be made from cherry with mortises and tenons. I'm drilling my tenons with a drill press and as a test I used a 3/8 inch straight router bit in the drill press. The only problems I ran into was that it was a little jerky and rough but with some extra clamping and care, I managed to make some decent 3 inch long slot. Overall however, it was a pretty sloppy process and I'm wondering if there's a better way using my drill press.
A couple details. The legs and the stretchers are cherry. The legs are 1 3/4 inches square, the stretchers are 7/8 inches wide. My mortises are about 3/8 wide inches x 3/4 inches deep.
So looking at what's out there I'm seeing upcut spiral and downcut spiral router bits, hinge mortising bits, etc, etc. In the woodworking class where I'm trying to learn this stuff, I think the setup was some sort of spiral bit in the drill press. Needles to say, I'm a little confused and overwhelmed..
My question is, which of these would work best with my 139 dollar Craftsman drill press for what I'm doing? These won't be through mortises (if that's the right term)
I welcome any and all suggestions and on drill press mortising and what bits and /or hardware and technique you might recommend.
Thanks so much.
