The first lot of shopmade tools are ready for the toolbox - a set of chisels in a box.
The box may be removed ...
or used from the toolbox.
Below, note the guard over the ferrules. This locks the chisels down. The box could be upended without their moving (necessary if moved by baggage handlers).
There are 9 chisels, including a fishtail for clearing the waste of pins. The blades are M2 (HSS), 80mm long (a little longer than a butt chisel), 3mm thick and hollow ground at 30 degrees. The handles are West Australian Sheoak.
The brass ferrules are semi-fake, on purpose. The blades are attached with tangs, epoxied into the handle, and the ferrule is filled with epoxy, gripping the steel shaft and acting as a bolster. The shoulder shape is influenced by Japanese chisels.
While the shoulders appear square, as with firmer chisels, these are all bevelled with minimal lands, and the taper will fit inside the shoulder of a socket angled at a 1:5 ratio (11 degrees).
The sizes are geared towards detail work, especially dovetailing. All metric. So ... 3/4/6/8/10/12/18/25mm. It is likely that I will replace the 10mm with a 6mm mortice chisel (already made) ...
M2 is hard steel. It takes and holds a good edge. Overall, they are light, pare well and handle chopping.
