Twin I-Beam Kingpin Knuckle part 1

Over the week end I was able to get back to the Twin I-Beam project. I machined the top and bottom of our prototype kingpin knuckle. I had already machined out the mid section a couple weeks back. Here are some pics of the progress.

Nitro Circus pays a visit to Summit Machine.

Yes, that’s right! NITRO CIRCUS made a visit to Summit Machine. Something about Jim having his eye worked on triggers them to need us….strange coincidence. (It was right after Jim injured his eye last year they came by.) Anyway, last time we did some work for them it was to make some chromoly passenger foot pegs on Travis’s motorcycle and some sturdier “axles” for their “big wheels”. This time it was making some camera parts for their production crew. Pretty cool nonetheless, and thanks so much to Mike for working his tail off this weekend to get the parts done.

Summit Machine’s 9ii “Round 3″

First picture is a side plate anodized and ready for bearings and seals. The second picture is the gear cover also anodized in everyone’s favorite color Purple. It’s one of the colors in our logo so I saw it fitting. Looking back on it I’m not sure that was the best idea. The third and fourth pictures are more of the stub shafts. This time with most of the black scale from heat treatment removed.
