Elnathan,
Yes, this is the one in Mark Baker's article.
J Vavrek,
3X pipe is a mild steel drawn (seamless) tubing. The local welding shop has it in stock. It can be cut as nicely as iron. I had shavings up to my knees putting the flats on that barrel! Took about 20 minutes to put a flat on.
The "bore" of this pipe is pretty smooth already, so doesn't need too much fine -boring. Cuts nice as I said.
Ed the black;
If it was .62, I'd still be boring it! LOL! But it Would be a lot lighter! Thanks cobber.
First game with it was a feral cat. always scrapping with ours. Dog treed it one night and my son John went out with me. he held the torch on cat and I let fly.
It's the first time I ever saw a cat fly out of a tree Upwards...
Only problem is that rounded heelplate;
It slides on slick surfaces. Got to watch where I lean it.
Not a problem, but you may have noticed the not quite correct stainless touchhole liner. It works. :-) A regular touchhole liner will nearly fit inside it.
