该多部分视频将帮助您确定蒸汽机基础/机架加工的良好起点。 我将加工十字头滑动表面和气缸安装特征。 两端均添加了定位功能，以供将来操作。 如果您要构建此套件，那么值得一看。 参考的Notch视频：https://www.youtube.com/watch?v=XcKNo1fA_rw&t=249s Patreon支持：https://www.patreon.com/joepie网站：https://www.advancedinnovationsllc.com网络商店：https ：//www.advancedinnovationsllc.com/shop。

  4. I had that "flop" problem on the Y axis and I overcame it by replacing the chromed steel handle with a very much lighter aluminium one that I made – the only drawback to this is that the aluminium makes for a dirty hand!. The X axis also suffered from this symptom because the manufacturer had cut the handle key ways such that the handles were on the same throw so I cut a new key way in one of the handles at 180 degrees opposed, thus placing the handles opposite to each other giving perfect balance and hence removed any "flop" tendency. Your videos are very instructive as to how one should evaluate a casting to get a good balanced outcome for all the required machined surfaces and absorb the inevitable casting inaccuracies.
    Thank you for all the trouble you go to with these videos to impart your knowledge and experience – it is very much appreciated.

  8. You have 100k subs. Please get a better microphone, it would increase quality of your videos so much. People can sit through poor resolution, but low audio quality is just something else…

  9. Thanks Joe. Another video of yours that I've saved to my playlist to watch over again. Love your teaching style. Direct and so respectful. ????? Joel…..

  12. Hey Joe, I am enjoying your training videos as I have recently acquired an interest in small steam engines. Your detailed explanations are much appreciated. I would like to try the PMR kit that you are doing and wondering if you plan on doing videos to the completion of the engine? I hope so.

  15. Dear Joe, thank you for sharing your know-how: for instance the boss you quickly make to seat in the castings.. just a real pro approach! Clamping, taking messurement and doing the opperations all at once: genius. Looking forward to learn as much as possible. In the meanwhile stay save. Greatings from Switzerland

  16. Drilling and tapping holes in the raised center rib of the fixture would allow the use of a hold down across the body. Any thoughts on why or why not to do it?

  19. Joe, 43 years of experience here and you taught me a few things in just this one video.

    I say to the next generation. What you learn in this series here applies to everything, everything you do.

    This is more than a model, it is an education. 1/20 horsepower or 1,200 the principles are the same.

    Keep up the excellent work Joe!

  20. Joe. Seriously. I love your work but while you are a machining genius your video work doesn't do you proud. An y chance you could get a video expert to come in and help you with the camera?

  21. David Richards : old steam powered machine shop 43 designing a steam engine slide valve. This video will explain all the parts movement and their relationship to each other. Thanks joe

  23. Nice. Having everything symmetrical is always better even if majority of people will never realise how much work went into it. Nice to also see someone who realises there are plenty of people out there who don't have DRO's.
    Thinking of what colour to paint it yet?

  29. Joe, thanks so much for your tutorials. I am attempting to make a PMR #1 engine, and I have been struggling. Your videos have provided me with some significant insight and techniques to help me move forward. Your approach to understanding the castings before actually setting up on the machine tools was a huge revelation – and I now realize so very fundamental to the process. Thanks so much, and all the best.

  31. Would of liked to see some video of the initial setup. Your description of the cheese plate didn't make immediate sense to me. Nice to see how a professional machines castings. Think I'll pick up this model myself.
