........ Please don’t hesitate to offer a few hints if I am doing anything wrong or if there are better techniques for me to try next time.I wonder if annealing is one of those time-temperature processes, that can occur at higher temperatures over a short time, or lower temperature over a longer time. Perhaps the observed reduction of the movement tendency is just an extreme of the time element at ambient temperature. Perhaps the peeing on it made everyone avoid touching the casting until the event was forgotten, and that took long enough. Slow might even be an advantage compared with quicker heating. It would be interesting to know more about it.
Hi Bear, great to have you along. I have also been following your build. There have been so many comments on Elmers engines over the years that I am sure that I will have to try one soon. So most interested in how yours goes..........Of course, that meant next I had to clean up the cover casting. The outside face was machined so I had a reference surface, but I had to face the inside surface. It was tricky setting up parallels to support the thin casting yet still have the face clear above the jaws for machining. I couldn’t see how to clamp a component less than 5 mm thick direct onto the table. I think Willy has one of those thin part vices, but he is a bit far away, and postage is so slow these days.............,MJM460
not to be stressed during such critical operations could only mean one is not aware of what could go wrong. The stress ensures concentration.
