    Default My Simple Oscillating Engine

    G'Day,

    I finished my version of Steve's Workshop Simple Oscillating Engine. I had the plans for awhile but watched Emma's Workshop on Youtube so she inspired me to do one.

    I don't know why the pictures have turned 180 degrees?

    Hello Bwal,

    Well done it looks good.

    Thanks for the last pic especially - didnt realise there would be so few parts and each one looks relatively achievable for somebody who has never made an engine.

    Am guessing the critical skill is in making sure they all fit together properly in order to ensure that it runs.

    When you were making it did you ever make any mistakes and then have to remember them and compensate on other pieces ? Or is that not really possible with an engine project ?

    Hi,

    They are pretty easy to build and hence pretty to make small mistakes on. In the last picture there's 4 pieces that I had to re-do. The brass flywheel I tried to use a endmill in the TS drill chuck and it cut way oversize. I'm hoping to salvage the brass for another project later on.

    I used a random spring from my spring box and it was a little too stiff, so when I attached the cylinder to the pedestal I was tightening it up too much. So the engine would get stuck at TDC and wouldn't run. I made a new piston (a 3 piece one instead of the single brass one), enlarged the ports etc, milled a small spring recess in the pedestal and made a new bearing before something clicked and I loosened the spring and she ran.

    The scratchbuilt engines are tolerant of minor mistakes, I've made plenty of mistakes on all of mine and after a bit of tinkering they all still run. I'm going make a Bill Lindsley designed Beam Engine next then try my luck on the Stuart V10 casting set I have (got for Xmas last year). I enjoy making them.

    Ben

    I had the same problem a while back, any pictures I uploaded from my tablet were inverted, the problem has resolved itself since? Anyway, what I had to do to get the pictures right way up was copy the image from the tablet to my hard disk, then upload to the forum from there. Sometimes that didn't work either so I brought the image up in Paint and saved it to my hard disk and then uploaded from there.

    The problem has since resolved itself and I can now upload direct from my tablet???

    I don't know what happened? I have a iPhone. I used to be able to send my photo's directly from my phone via txt to my hotmail account and download to my laptop and then post on forums. After the last upgrade and my wife & kids playing around with my phone I now have to send the pictures via Mail (instead of txt) and download et.c et.c . Now my photo's are downloaded and saved to my laptop and are the right way up, but when I post them on any forum they are skew if.

    Not really sure how to fix it. And I should add, when I first started sending the photo's by Mail, and posting them they came out alright. So not sure what has changed.

    Ben.

    Yep same problem I had, but the problem has resolved and now I can post straight to the forum without problems. I suspect it's updates, you've probably noticed every time your computer/phone/tablet is updated some of the settings on your device have changed. I turn off updates, more trouble than they are worth. Alternatively you can back up any files and restore to a point when everything was working. In the case of tablets/phones just restore factory settings.
