Awesome handy work. Looks like you spent some time with the wax-on...wax-off

I started to laugh when I first saw the photo...
It reminded me of a cartoon where the guy pulls out a gun with a long barrel, and
the other guy says...Oh YEAH!!! and pulls out something like yours.

Keepup the good work. I did something crudely similar to a Crosman 760 pump just for S&G.
