Good luck with this project, I envy your ability to think BIG. That same engine inspired my little engine that I detailed here:- http://www.homemodelenginemachinist.com/f31/twin-d-oscillator-12744/ Ian |
| MetalCaster:
Thanks Ian- Your build looks great, nice engine. My wife complains sometimes that I have to do everything on a big scale, but for me big is a 12 foot flywheel. I have had serious conversation with my buddy and co-contributor on this engine about building it full size with a 12" dia. flywheel. But I need to get this 1/2 size one done first. Crawl before you walk, walk before you run, as they say. |

Pat that looks a nice design of oscillator. Well done on the casting it is looking good, bet it was some moment when it started to melt! is it usually the case that you need so much fuel to carry out these melts? |
| MetalCaster:
Thanks Nick- I was really beginning to wonder if I would ever get iron to melt. It can be a bit of a trick if you don't know what you are doing, and at the time I definitely did not know how to adjust that burner. It was a Hallelujah moment for sure. I could envision the clouds parting, and the sun rising majestically, the sound of the angels singing the chorus waifing town from the heavens; sort of hard to describe the feeling; I had dreamed melting iron for years, but really did not think I would be able to pull it off, and had been told by more than a few to not even attempt it, it was too dangerous. It was sort of like this (at least in my head anyway): Well it is dangerous, but that's life I guess. If you do the research, and study the dangers, and take the necessary precautions, and you have a technical flair, you will be fine. If not, you may have trouble. |

I will be following your big build with great interest. My Dad served his apprenticeship as a Millwright on Clydeside, shipbuilding. The spanners to tighten the nuts on the boiler stays were 6ft. long! Ian |
