First day of building

Ladies and gentlemen, it is a momentuous day in history; I have finally commenced the build of my very first machine design! It’s a good feeling indeed.

Alas, all I completed today was the machining of the 2″ pins. It was a start though. To do so, I learned to use our monster bandsaw, and re-acquainted myself with a lathe after 4 years not having used one. I took instructional video of it, too. To be compiled into an instructional ASAP. I bought the shaft this morning at Competitive Metals, along with the 2.5″ shaft.

Learned a very valuable lesson today- cut the pins to be about 1/16 ” longer than you need them to be. Its pretty hard to get a perfect cut on the bandsaw, so I ended up lathing off the ends to make it square. Its OK if the pins don’t go all the way thru for these, but it’s sloppy, and I don’t like sloppy.

I got the go-ahead from grandpa to use whatever we have at the shop. I just gotta keep track of it so I can pay him back by the pound.

I also started making the washers to be welded to the pins, but was called home for a delicious dinner instead. Will finish those tomorrow, and weld up the 2″ pins.

I learned about a tool for torching circles with the torch, and made some washers with that. My grandpa made the device in the picture. Its basically just a rod with a slide on the center, a horseshoe at one end to hold it by the hoses, and a ring at the other to go on the torch head. Theres a pin on the slide that you put in the punched center of your circle.

    Excellent, great documentation, inspiring open source, economically significant info exposed. Please keep a log of purchases made as they happen on the log, in addition to the Bill of Materials.

    Just found your build up and have to say good job and good luck. I want to build an Ironworker myself and liked the simplicity of the Pirhanna and Scotchman. I am looking to build one with less capacity than yours say 50-75 ton simply because I have numerous pieces of heavy plate 1 1/2″ thick by 8″ tall by 86″ long. I am thinking about placing two pieces together to have a 3″ by 8″ by however long the macine needs. How do I find out if this will be enough steel to give me say 75 ton on the hole punch with 10″ of throat depth? Thanks
