Mortise chisel: Part 2

I marked out the angles on the mortise chisel by “feel,” just by sort of looking at all of the pictures I’ve seen and guessing. With two sides cut away, it looked like this:

I cut out these sections with my larger rip saw. It would have taken forever with anything else. Then I used a block plane to smooth around the oval. I nicked the blade of the plane against the chisel bolster doing that. Boo. Grinding that stuff out is always such a pain.

Following the plane, I used a spokeshave to further smooth the oval shape, then, finally, progressive grits of sandpaper on a block to do the final smoothing. This sequence was quick.

A couple of oil/varnish blend applications later, along with the requisite sharpening, it was ready to use. Here it is with its first test mortise-and-tenon joint (upper left, not that stuff to the right):

It’s a lot of fun to use. Best of all, it’s fast.

Mortise chisel handle: Part 1

I’ve been jonesing for a “real” mortise chisel for a long time now. My obstacle, however, has been the irrational cheapskate inside of me. There’s been a lot written about the English “pigsticker” style of mortise chisel lately, and I’ve been trolling ebay for a cheap one or one without a handle. I finally got my hands on a handle-free sample a couple of weeks ago.

Made by W. Butcher, it has a strange width–something like 9/32″. This is close enough to 1/4″, I guess. Its cutting edge is laminated to a softer metal for the rest of the blade.

Unfortunately, it was dubbed at the tip when I got it, and it was a lot of work to flatten the back (I took the dubbing problem from both ends; shortened it slightly and flattened the rest off). You would think something that small would be easier to flatten, but the steel is really quite hard. I used Norton 3X sandpaper on a granite surface plate, grits 80 on up.

After doing this task, I set out to make a new handle per Derek Cohen’s instructions. Putting in the hole for the tang was a real pain in the ass:

The wood is yellow birch. We’ll see if it holds up. Next step is to shape it, then finish sharpening the blade.
