Frozen Cable Time
Sunday, December 20th, 2009We arrived at work yesterday figuring that the sub-zero cold, wind and snow would keep most of the customers away, leaving us with time to work on some projects. The highest priority is reconfiguring our workshop after building a massive, floor-anchored, steel frame to hang our electric bike lifts from. It’s a great improvement but not entirely our own initiative. The lifts, you see, were bolted into the 150 or 200 year old wooden beams of our ceiling… and thus the floor of the neighbors upstairs. Though the lifts are nearly new and operate very quietly they do make some vibration. Standing on the concrete (over sand) floor we never noticed this vibration but it drove the lady upstairs crazy. Actually she’s complained very vocally and angrily about a lot of things, apparently calling and writing every possible authority on a regular basis. Most of her complaints have nothing to do with our activities (there’s another bike workshop next door and several apartments have been renovated), but the vibration was a legitimate issue according to the various city inspectors who visited to investigate.
So the city ordered the building owner (a social housing corporation that manages tens of thousands of properties) to fix the vibration problem. It was decided that the only solution was to totally isolate the lifts from the floor beams, and the only practical way to do that was to build a steel frame all the way to the floor. We’re very fortunate and thankful that they took care of the job and paid for it. But it still requires an investment of several days of our labor to refit the lifts and lights. We took the opportunity to make them fully adjustable on both X and Y axis as well as angle, and now we’re adding more lights. I don’t think a workshop can ever have enough light.
Anyhow, this is all we were thinking about yesterday morning so I got busy with the scaffold, drills, plugs, screws and wiring to hang the fluorescent boxes on our ancient ceiling. And then the first snowy Cargobike and customer came in:
Customer: “My bike is almost impossible to ride. It’s really slow, and I think the brake lever might be broken.”
Mechanic: “I’m pretty sure your cables are frozen.”
Customer: “But I think there’s also something wrong with the brake.”
Mechanic: “The brakes are probably fine but they’re being locked by the frozen cables.”
Customer: “Oh wait, now it seems to be fine.”
Mechanic: “Sure, your bike is indoors so the cable just thawed, releasing the brake. It’ll freeze again a few moments after going outside. If you can wait 15 minutes I’ll fix it.
