The inspiration for this engine comes from a haulage engine on display at the Manchester Museum of Science and Industry, the engine was built in the 1840 and was used to haul wagons up an incline at an alkaline works, being an haulage engine it would run in both direction via a simple slip eccentric. The model will be far from a scale model of this engine as I intend the design to be as simple as possible suitable for beginners, so I have taken huge liberties in the design, it will use the same cylinder and piston valve as my Horizontal Mill Engine and Vertical Cross Engine. This is the assembly drawing I had planned on using a cast fly wheel but had problems sourcing a suitable casting they were all too big and chunky, fly wheels of this period were far lighter affairs, in the end a had a blank laser cut that I've machined up and painted I've posted this else ware on the forum, but for those who missed it this is the finished fly wheel. I've nearly got all the cylinder parts finished but as I've used the cylinder for other engines that I've ran threads for I won't bore you with its construction. As this is very much a work in progress I won't make the drawing available until the engine is finished and I've caught up with all the changes there inevitably will be. Cheers Stew |

Thanks Jon looks like you're the only one to read it. Been working on the Beam made from a length of 1/8" * 5/8" mild steel first job mark one of the bars with all the hole position and mark the other with just the centre hole. Then drill all the holes in one beam, and just the centre hole in the other, then clamp the two together at the centre and drill the rest of the holes through the other that way they will be exactly the same. Add a few more clamp bolts just so nothing will move. And set to with the mill or a file to get it to the tapered shape and finish of the rads at the end with a couple of filing buttons, Next up machine up the 8mm spacers tapped M3 then make the clamping/pivot bolts. This is what it looks like completed. I've nearly got the con rod finished but I've been called away on domestic duties. Stew |

Don't worry Stew I'm watching :) |

Me too, Stew! Is there a list anywhere of your engines that use the same cylinder? I intend to build them all. Chuck |
