One of the guys on Instagram made a set of chisels from O1 tool steel very similar to the steel I used for my French style moulding planes. I was thinking about making some chisels from this stuff, and went so far as to order some steel in 1/4" thickness for exactly this purpose. The toolmaker on Instagram inspired me to go for it.
My plan is to make some firmer chisels, tanged with some kind of octagonal handles. I thought that my J. Jowett chisels would be good ones to model.
|I like these chisels, and hope mine turn out as nice.|
|I think I might have a problem. This is my latest pile of Swedish chisels.|
To grind the shape on the un-hardened tool steel, I made the decision that I needed some kind of belt grinder for major waste removal. There happened to be a cheap Chinese belt sander at the local grocery store for 29.99 Euros. Perfect, just in case this ruins the tool. I don't really see myself needing this for woodworking.
|Here is my setup on the balcony for using this as a belt grinder. It came with the clamps and seems to be sturdy enough.|
I found that this works relatively quickly with a 40 grit belt installed. I use a wooden batten for stability and a little pressure, and move it back and forth from the tip of the chisel blank to the back of where I want the taper to stop. This makes a nice taper of just about the shape I want.
It probably took 15 or 20 minutes on this 3/4" wide blank. The chisel in the photo is the Jernbolaget that I used as a reference.
The steel blank is 18" long, plenty to make two chisels. In fact, the bench chisel I am making uses only about 8" of the blank, so if this works, I should come away with a set of longer paring chisels as well.
My plan is to heat treat and finish this chisel to see if it works before I spend a bunch of labor on the whole set. I think I may grind the longer side of this chisel blank too, before I cut it in half. It seems to be easier to hold on the grinder that way.
One way or another, I will post on the finished project when I get it done.
