When I started making the small dovetail chisels I did not have the ability to make a chisel as small as 1/8", however I had several request for this size so I started thinking about how to make this little chisel without having to make a large expenditure on a magnetic sine chuck.
It required making a dedicated jig just for this size. On a 1/8" wide chisel with 20 degree side bevels and near zero land on the edges the flat left at the top is only .040 to .045 wide. This is the amount of area left to hold after milling the bevel on one edge. When I look at the completed chisel blade now I'm still amazed that I'm able to hold it to mill the second side. Nevertheless the jig works.
The first pic features the 1/8" chisel with Macassar Ebony handle, the second pic features infused curly maple handles and has the 1/8" chisel on the left in comparison with a 5/8, 3/4, and 1" wide chisel
