Steam Power to Remachine Steam Engine Parts

  • Old Steam Powered Machine Shop #75. The Lily steam engine cylinder head, slide valve and steam chest cover are remachined on a shaper, lathe and planer using only steam power in my 1925 line shaft, steam powered shop. I put this shop together, as you can follow on my older videos, to show how it would have been done in a time before municipal electric power, electrinic measuring, CNC, indexable tooling, etc. when set ups and machining operations required some thought. See my Community pages for shop news and updates. Thanks for watching this one.....Dave

      Probably the best thing for this shop would be to turn it into a museum, that way it would be kept intact. It would be great if the Smithsonian would take it but they probably have their own. Maybe family could keep it running.

    I like watching old machines working. What I like alot about your channel is you don't spend an inordinate amount of time showing how to fixture a piece for machining. Some machining channels go into great detail on how to fixture and dial in a piece of work but I would venture to say that most folks are here not so much for the setup as they are for the doing and end results. At least that's why I'm here. Thanks for posting.

    Love the videos man. It’s always a treat to see how we used to machine thing in the early days of the industrial revolution.

Just finished my schooling this summer and am working my way through a full time job running and programming cnc machines.

    Mr. Richards this last week I made a compound sprocket of 12 and 36 teeth for a steamer built from a Meccano Constructor Car and a vertical Empire Steam Engine. I used my Southbend lathe, Atlas shaper, and Hardinge mill. My machines are old but not as old as yours. You are one of my heros in life and hope this finds you well. Greg.

      By the way if you were to change your generator over to AC your generator would produce a lot more power and be more efficient. It would require you to change out the commentator to two separate commentators with brushes for each. That way you don't have all the arcing and shorting. It is why Nicola feels designed the AC Generator and the AC motor.

    • @Blacklab412294
      @Blacklab412294 Рік тому

      ...Nicola tesla.. Then all you would have to do to make DC would put the AC through a Rectifier. There is away to run you lighting at 110 volts using the out put from you 12 volt generator ( if that is the case) , you could use an inverter with a battery (see Amazon for inverters).

    I remember when I was young I worked at a paper mill that was steam driven via line shafts. In this case these were steam turbine with electric motor assist on one of the machines. A third machine was converted to electric drive at some point in time.
    This old paper mill,was tore down a few years back but was replaced by a huge new mill near by.
    One older paper Machine had cast iron spoke and hubs but the drive gears had teeth made originally of wood segments. By the time I started there a replacement plastic nylon type material was being used in place of the wood. That particular machine was in use for ninety years. It was driven by one five hundred hp steam turbine. The turbine was extremely small, maybe three feet at the most and was located in the basement line-shaft tunnel.
    The largest of the three machines had a 1500 hp turbine and several electric drive motors that served as assist drives. In the case of these drives a line shaft drove six separate gear box drives that could be controlled via a snowmobile type clutch drive bands. It was a wonder of mechanical clutch and gear box. I had to help rebuild and replace one of these units. The gear box was about four or five feet square and had many input and output shafts. It took five of us all day to remove and open this gear box. The rebuild took days to extract wore out parts and replace some of them from a donor gear box. We tracked down a gear box from a supplier who had salvaged it from another company. It think it cost something like 250000 and we’re glad we found it. The other parts were made in our machine shop. I wanted to save these machine parts when the mill was being tore down but because of they were being written off for taxes they not only could not be saved but had to be cut open so no one could salvage them for parts as we once had done many years before. We did manage to save one water driven stone wheel grinder used for pulp production. It dated from the 1890s or so and was driven by water wheel and then later by electric motor. It had four pockets that were feed by hand with 25 inch long logs. A water driven ram would push a pocket full of logs into a grind stone. A couple of times a day the stone had to be sharpened to obtain the desired pulp needed. This is now setup on public display in a park like setting. There were four other things I wanted to salvage but could not. A friend of mine did salvage a steam driven fire backup pump in perfect like new condition. It was never used for anything other than as a backup pump and was tested weekly for something like ninety years or longer. My friend found a museum a hundred miles away to take it. I wanted to keep it in our community but was glad someone got it to save from the smelter.
    I salvaged as many brass inspection port holes from old generators and steams gauges that I could gather. In time they will find a safe home to protect them.
    Not sure if other people would find this sort of thing of interest. I really liked designing systems and have several manufacturing processes to my name. The old process were crude yet were very interesting in the simplistic and complex way of doing things, there was always a real danger that someone would be killed by these machines. I’ve had to treat many people, recover bodies, feet and whole arms from machines. I’ve also treated so many heart attacks I lost count. The jobs were very hard , hot and could be dangerous.

    As late summer came I chanced to trade a day of work wage for a South Bend 9. And, am happily planning the full install to my shop. I had the clean and lubricate bench just at the shop doorway, where I managed all operation to restored precision. I think I matched a 1938 serial number, as found stamped to the bed. And wear is modest to the ways.
    Why I enjoy the posts in part is to see exactly how shop work areas are laid out to advantage in particular machine functions. That blend of best use of space and tool compartment, holders,
    and bench. Very natural to that job production as full care of tooling and lubrication of components. As to each job, the best quality of finish and thoughtful selection of tools to reach best fit. In my view, a domain of machinist that simply is fundamental and so is actual to these line driven tools that match modern electrical drives.
    I watch, listen and learn. And I thank you for the time and effort to the posts, where I so enjoy the perspective and finish as found to steam. *M.

      As you probably noticed, we aren't to concerned about firing the boiler although the water level is carefully kept in mind. The engine is so oversized that every thing runs fine with pressure between 70 and 25. ...Dave

    What a great treat. Really enjoy your video's. Why did you use the planner instead of the jointer? I'm partial to a jointer but really enjoyed watching both in work. Thank you.

      Dave was working on the shaper in first part of the video, in the second half he was working on the planer this is what I was referring to . I appreciate your concern .

    Great video as ever, David! How do you stop everything rusting while you’re away in Florida for the winter? Everything in my shop rusts but I’m in wet Scotland..

    Dave, thanks for sharing again! I look forward to the next videos. However, _please_ remind me what your explanation is (from a previous video, I think) about what makes the planer sound like it is grinding itself away -- is it the sound a drive belt rubbing or something like that?
