BL-22 Hammer Extension
Building
I started out with a piece of stainless steel rod and turned the od
to 3/8".
The overall length of the finished hammer extension is 1".
Next I knurled the end of the stainless steel rod. ( approx 3/8" wide
)
I use the knurler that came with the Harbor
Freight 39083 quick change toolpost
Next I center drilled a hole for the setscrew.
I used the correct drill for a 10-32 tap.
I did not tap the threads at this time.
Using my Grizzly mini mill I milled a slot completely through
the 3/8" rod approx. .370" wide. After milling I had to use
a small 3 sided file to square up the hole until the proper
fit was achieved. I then cut off the excess rod.
After filing was completed I placed the extension back in
the lathe and hand tapped the 10-32 threads.
I also turned the extension around in the chuck and
faced the back side.
Finished !!
