I was cleaning up a science classroom in one of the high schools where I tutor, and I found a Jensen Model 70 toy steam engine in one of the cabinets.
These are toys from a past era: first, it is a model steam engine, from back when parents encouraged their children to pursue manufacturing and power-related work, and second, it is a dangerous toy, by modern safety standards.
Rather than the dead eyes and soft edges of a Telletubby, this toy is made of steel. Kids put water into a boiler (that plugged into the wall) and pressuready was released through a valve to spin a wheel at high speed, or to sound a whistle.
What’s not to like, parents? Water, electricity, pressure, high temperature, steam, and a whistle?
Anyway, I have been rebuilding this for next year’s classes. I will use it as a demo in several schools. So far, I have replaced the broken sight glass for determining water level and replaced both gaskets for this window. I think it is ready for a test run, which I will perform thus summer.
I will keep you in the loop as I tinker with this steam engine.
Thank you for reading my post.
