I also made my own tools but used a little different method. I bought a bunch of air chisels at a tool sale. I then cut off the tips and welded some cheap sockets onto the end of them that were slightly smaller in diameter than the replaceable soft face hammers inserts from NAPA. I then chucked up the hammer faces in my trusty Shop Smith and turned them down until they fit in the sockets. Then I put the chisel in my air chisel and seated the hammer face in the socket.

It looks ghetto but works great for what I do.
