I've done a lot of things myself in my garage (like milling my own heads n jugs with sandpaper and a table), but I would never try to do what you're talking about without the proper equipment and knowing a little about what I'm doing.

Its like $130 and he supplies the rod too. Even if you decide to try it yourself, give him a call anyway. He can explain the whole thing to ya. He's a super nice guy.
