Journal: The Sound of Calamity

Project: Skip’s been working on improving – and proving – our frame jig accuracy. We have three jigs and w;er ensuring that they all match, and that they are all correct. I’ve got a bunch of photos to post.
Note: Arrived late to work this morning. Super tired from the weekend.
Project: production tracking; working on improving tracking of labor hours per frame. We’re doing really well and we’re looking at parsing hour tracking in some new ways.
Time Marker: Dan P. is leaving Seven Cycles; he’s our shipper. He and his wife are moving out of the area.
Development: Working on a new production methodology – something that we’ve been working on for quite a while – that will have our framebuilders take on more of the overall process. Framebuilding with a capital F. Two builders per frame instead of three. This is really cool.

Consulting: Talked with Derek at Cornell about fatigue endurance’s relationship to bicycle frame stiffness degradation. As, I’ve mentioned before: no relationship. Some of the points we discussed included:

Fatigue testing article from 25Seven – that’s how he found me
Material modulus does not change in any real world bicycle use
Bicycle frames are more often designed for impact resistance – yield and ultimate strength – rather than long-term fatigue cycling – real world usage
Steel frames rust internally and that effect on frame stiffness – often confused with frame “softness”
Aluminum doesn’t actually have a fatigue endurance so eventually, if you keep riding the bike, just like life, it will fail

Design: Wrapping up the Studio Kit this week. I’m way behind on completing it.
Event: Geoff Martin took some really nice photos at the Studio’s 2nd anniversary surprise – a surprise for me – party.
Bike Design: Created a few posts about some old projects from the Merlin Metalworks days. Three related projects. Just a bit of information for the moment. More to come, later.

History: I was looking at this page today – scroll down. Lots to say about it. I’ll have to get back to this later.
