Topic tags/keywords: joining mortise

I watched a video from a link in one of the LJ posts that showed a japanese LJ drilling three holes and then using a square chisel to complete the mortise. The chisel was square, hollow, appeared to be completely steel and he struck it with a metal hammer.

I searched woodcrafter, rockler, tool king and amazon with no success.

I’ve never done a mortise joint before, but want to try without buying a delta at $300. The tennoning jig just reviewed looks real good to me, but I need to get the mortise figured out also at a more reasonable price.

Are the corner chisels from everyone any value for a mortise joint on table leg?

This is initially for one project and may never be used again. My project is pair of end tables and coffee table for my own home.

Steve.

It almost sounds like they were using the chisel portion of a hollow chisel mortise machine.

I just purchased a set of these (4 different sizes in the set) from Woodcraft. They had two choices. These are called hollow motise chisels and come with a center auger bit that goes down the middle of the hollow chisel. I am surprised that you did not see these at woodcraft (unless I am not understanding what you are talking about). Woodcraft had two different choices.

1.) The box set of 4 like I bought with the center auger bit included. These are made in Taiwan and were very in-expensive. I needed them for cutting square plug holes so went the cheap route. I don’t use a hollow chisel mortising machine or a drill press adapter to cut mortises.

2.) Individual chisel/auger bits made by (I believe) Freud (or Jet maybe). A single bit was about the same price as the 4 box set that I bought.

Take a look again for hollow mortising chisels and I bet you will find what you are looking for. Good luck.

Here is a link to a bunch of videos for hand cutting a mortise:

From what you are describing, you could probably use a forsner bit- the same diameter as your tenons- and a couple of sharp chisels.

Lew – danr; You guys may be right. I have never seen a real mortice machine chisel. Sounds like a road trip in the next day or so.

Here is the link to the Woodcraft box set of 4.

I’m sure they can be purchased elsewhere also.

Good luck

Lew – I don’t have a chisel right now that is that size, so would have to buy one anyway. That guy really made it look easy. Hard to believe the guy with Freud shirt was so agreeable or do they sell chisels?

Danr – I was hoping to buy the one size I needed for a little less. Again, probably only the one job.

I think that I saw Daniel Pearll use a square mortise chisle to put in square pegs ion Greene and Greene furniture.

Thats the way that I do it also.

I have tried using a hollow mortising chisel and mallet with the bulk of the material removed by drilling on a drill press. It doesn’t work very well. Hand mortising as demonstrated by Stefang in his blog a few days ago is faster, easirer and better, IMO.

Skarp – your post of the noho91 video is what started me on this trek.

Next question is, besides the final look, what is wrong with rounding the tennons to match the drilled holes? Not sure how to really match the radius.
