A totally predictable failure pattern, I suppose. I did the only natural thing here and glued it back together:

I don’t know how long this repair is going to last.[*] In theory, it should be okay if I manage to strike in the center of the mallet, but then again, the ultimate reason that this happened was because I didn’t hit the chisel handle in the center.

There’s a lesson to be learned here. Maybe one or more of these will help in the future:

• A bigger mallet for bigger jobs like this. [note: see Joel's comment below on why this may not be the greatest of ideas]
• Strike in the center.
• Make the mallet out of wood with an interlocked grain.
• Not hit the chisel so hard.

[Edit: July 24, 2011, about a year and three months later. However, the new break was totally different.]

Yeah, I know, it’s not too exciting, it’s just some wood.

This stuff was quite cupped when I started out, so I had to do a lot of work with the scrub plane to get it flat. To do so, I decided to put a second row of dog holes in the workbench so that it would be easier to plane across the grain:

To use them, just add some dogs in the appropriate holes, as shown here by this evil piece of beech:

It’s been working well so far. I’m considering adding one more at the corner so that it really doesn’t have any room to move around, but it’s not important right now.

Why, you ask, is that board evil? Well, it’s from a piece of 8/4 stock, about 11″ wide. To get to the point of resawing it, I had to flatten one face. No problem, except when you don’t hammer in the scrub plane wedge enough. When that happens, the blade can pop out when you’re doing hard work. The overall consequence, then, is minor carnage. Ouch. I lost a few days of shop time from that.

In any case, this board is for another project that I haven’t talked about yet. I’ll post more details on it later.
