Air Hammer

[Carl Meyer]

Joe,  I ordered the one for 3/8 since in my earlier post I used a 3/8 bolt
with a shaft coupler and lock nut to set the depth.  A piece of rubber crazy
glued to the end prevented damage to the block.  I used this with a hammer
and it worked well.

So now I cut the head off the bolt but I had to sand the diameter slightly
to get it to fit in the 3/8 hole.  I  found that the bolt started to
mushroom very  quickly. I guess I could routinely  grind off the mushroom.
but I might try a grade 8 bolt that would be harder.

In your case, I'd find a 1/2 inch OD x 3/8 ID piece of steel tubing and
braze or even locktite it on the end of the 3/8 bolt.  Taper grind it so
that the punch will hit only the bolt end.  Now the tubing will act as a
guide for the driver and the shaft coupler will serve as a guide for the
tuning pin.  The tubing needs to be only an inch or so long.  Next time I'm
at the hardware store I'll see if I can find a grade 8 bolt long enough.
I'll let you know haw that works.

I drove a few pins today in a scrap piece of supply house pinblock.
Awesome!

Regards

Carl Meyer
