    you done it, despite the fears and then success but still humble. that's why i like you so much better than others. You show how a engine comes to life step by step and without mincing words too much - with all the insecurities that comes doing some operation the first time. this in my mind, gives some the push to try it out themselves, even without the best tooling. i would call it, the "just do it mentality"

    Wel done! That could have gone badly wrong but you anticipated the problems and produced a great result. The brake hone is easy to use and very gentle so you will remove only a tiny amount of material. Basically just taking the tops off the ridges caused by the cutter. Put the hone in the tailstock chuck and the part in the lathe chuck. Using a litlle cutting fluid on the hone run it through the bore at fairly low speed. It will take many passes to remove even one thou, but it gives the bore a nice finish. Dwell a little longer on the tight end of the bore and you may be able to reduce the variation slightly. Remember it is not a machining tool so it will be hard to get accuracy. Just go steady and check your dimensions often. If you do go a thou over make the piston to fit the bore instead of following the plan dimensions. Give it a try.

    • @learningturningmetal
      @learningturningmetal  4 ปีที่แล้ว

      Hi Tim - many thanks for the advice and explanation. From what I can tell the bore is out by 2 to 3 thou along it's length. I'm thinking that I might try boring it slightly larger once I get my between centres boring bar set up. It should be good practice, and if I mess up I can always have a go at making another one.
      I really appreciate the explanation though and it will no doubt come in handy in the future.

    I know I am several months late here , but to get a better start point for your center drill. you can use the V square of your combenation Square to scribe an "X". Just put the "V" of the combination square on the ruler . The ruler will cross the end of you round stock through the center . turn your stock 45* to 60* scribe another line to form an "x" will mark the spot to center drill. In the 3 jaw chuck you can still use you hammer to tap the end of your round stock while rotating the chuck. to line up the "X" with your center drill. Your run-out and interrupted cuts will be a lot less.

    Coming along now, the cylinder is one of the most critical parts, surface finish and parallelism are critical for the engine to run. As mentioned you can use a small brake hone to smooth it off and take out the taper. The tolerance for the piston fit is tiny, I’ve just got my model hit and miss running and had to re-make the piston as it was one thou too small, engine wouldn’t run.
    If you had a bigger lathe you could easy face, drill (one drill about 22mm straight in) finish OD finish bore and part off all in one operation.

    • @learningturningmetal
      @learningturningmetal  4 ปีที่แล้ว +1

      Thanks for the advice James. I actually purchased a small brake hone a while back after someone suggested it when I had machined one of the Stuart cylinders. I've never used it and don't know how to. With the hone material just 1 inch long l am concerned that I would actually increase the taper and make matters worse. If I understood how to use it, maybe it would alay my fears.

      Learning Turning Metal - by Andrew Whale even emery on your finger to polish it out a bit. I just know from getting my engine running that they are VERY fussy on bore fit and finish, and valves sealing too, any loss of compression either stops them from running or makes them only able to run fast. You should be able to roll the engine slowly over the compression stroke with no audible hissing and it should have enough stored compression to push the piston back down to bottom dead centre and even bounce back and fourth a little.

I am not aware of the SC6 or SC10, but if it comes from Seig and you have the space and cash I would go for the biggest you can get. Subscriber numbers don't matter to me, but three things do. 1: Documenting my learning experience. 2: Hoping to inspire others to get into model engineering. 3: Getting help and advice from toolmakers with decades of experience.

      Thanks for the suggestion. Unfortunately my toolholder restricted the size of boring bar. I suppose I could have explored other ways of holding a larger tool, but I wanted to avoid one job leading to another. The 10mm carbide shank cost £80.00 and that was cheap compared to others. Having already purchased a fixed steady for the job, it ended up being a quite expensive part to make. As you know, It can get to be a quite expensive hobby. But, you can never have too many tools!

    Ok good job.
    Perhaps a little constructive criticism, final cut was a bit noisy due to vibration, this will give you a poor finish.
    A larger boring bar would help, also a small cutting radius on the boring bar. I would say less rpm also.
    You can buy a small cylinder hone on Ebay for car brake cylinders that will increase surface finish and
    Possibly remove some of the taper.
    Hope this helps regards john

    Ok when you said this is the final cut just 4 thou to come of, you cut some out to get a size, then you filmed the last cut for the video.
    The first 6 mm or so didn't vibrate, I suspect you were removing about one thou or a spring cut, that should have been the final cut all the way
    through if that makes sense.
    Next cylinder hone, clamp the cylinder in the chuck and fit the hone in a drill chuck. Put some clamps on the bed so you don't leave the bore with
    The business end of the hone the move the tailstock in and out slowly by hand plenty of cutting oil or wd40 at about 100 rpm checking regularly.
    hope this makes sense have fun be safe keep up the good work

    • @learningturningmetal

      Hi John - well observed. I don't know what a spring cut is, but I suspect it's what I did without knowing it.
      I think that the bore is out by 2 to 3 thou along it's length, and from other comments I don't think that will be good enough for a hit n miss engine.
      So, I plan to make a finish it once I've got the between centre boring bar set up.
