HOW TO REBUILD A STUART MODELS 5A STEAM ENGINE – PART #7



How To Rebuild A Stuart Models 5A Steam Engine – Part #7 – making some new big end brasses to replace the malformed original ones. This is a simple operation, but I was not happy with the end result and will be making another pair. The holes through the brasses follow the holes in the bottom of the connecting rod and these are not evenly spaced. I will be making some more (off camera).

  1. Would it be possible to use oilite bushings in model steam applications? Just curious because it seems that oilite would work well but I have no idea how well it would work, if it has been tried before, or even if the material is easily obtainable. Thanks for the videos, I enjoy watching them all.

  2. Rather than using the fryolux paint, you could also use electrical solder paste. I probably would do this because of the choices in solder alloy and flux. I would probably Kester eutectic (63/37 Sn/Pb) with organic water clean up flux, due to the cleaning action of the water soluble flux.

  3. In my university course, I was required to thread nuts onto to length of M8 threaded rod. I got bored of flicking it and got a power drill to drive it to the correct location. Group mate saw me doing it and decided to copy me and instead cross threaded the nut and split it in half. Then a tutor saw what we were doing, flipped out and told us off. It was good day.

  4. Great video I learn so much every time I watch you working. You made mention of the advert videos I do try and let them finish but I think you tube is taking the mick when they are 3 and 5 minutes long. You have a kind of soul mate a guy called Doug is building a large boat have a look at SV Seeker you will enjoy it no I am not plugging him but he is like you in many ways a real human being. I am looking at buying a Clarke with a mill head not the best machine in the world but for what I need okay. Was it because the main bearing was sloppy side to side??????? is that why you made it again?. The reality with you Keith is you are prepared to share your mistakes as you only learn by your mistakes. I worked for a while in a school as a technician and I was surprised that children thought that getting it wrong is a bad some children even crying. I had to explain trying is more important than success. Then I would help them do it again. Your videos are my treat in the morning please keep them coming.

  5. Keith,

    Electronics solder paste isn't a bad choice for these sort of jobs. The melting point is quite low, it gives a good mechanical bond and comes apart easily when re-heated. And the good news is, that a pound of the stuff costs about a fiver

  6. My new lathe was delivered this week, though it currently sits on a skid in my driveway. Later today, I have some friends coming over for whom i will cook breakfast. In return, I'll hope they will help be get this 1200 pound lathe safely down into the basement.
    I may try to make a video of this – but the point in actual fact is that I am much closer to following some of your examples here.

    Though perhaps not the beautiful bunnyteeth at the end.
