My Forge, Air Pump, and Anvil

While at the Lost Dutchman State Park in Apache Junction, AZ we went to the Superstition Mountain Museum.  We met the blacksmith that works at the old west town outside of the museum.  He was a really nice guy and talked to me for a long time about forging.  We actually went there three times and I talked to him for a while each time.  He owns Iron Grip Blacksmithing.  One of the times we went there he showed me how to make little patch knives for black powder shooting.  I told him what I'm wanting to do and what I need to get.  He gave me a piece of railroad rail to use for an anvil (top left)!  I think it's going to work great.  He also told me how to make a pump blower that is light and portable.  I decided his idea was the best yet so I went back to Ace Hardware and got the stuff I need to build it.  I got a piece of 4" PVC, 1/2" PVC and some kind of sink drain tool that gets bigger when you tighten the nut on top of it.  I still need to get some metal pipe to attach the pump (bottom right) to the forge (bottom left).  Let me know what you think.
