    Vederstein's Folly

    Those that were following, know that this air motor was to be an "ultra-quiet" air compressor pump. Well the performance was abysmal. It wouldn't pump air worth a damn regardless of what I did to it. The only thing to do was to build up a base and reassemble the thing into an air motor...

    Designing a Quiet Air Compressor

    Now that the Dancer Engine is complete, I'm starting to think about my next big project: I'm going to attempt to build a quiet air compressor. I have some ideas, but first of all, one of the goals is to minimize the air pulses (chuffing) coming out of the pump. Note that this is pure...

    Ved's Dancer's End Engine

    This is a continuation of my Dancer's Engine. Because the previous Plans thread was too long, here's a new thread with just the plans. First couple of posts the PDF drawings:

    Mystery Brass

    I've had various levels of success with Online Metal's Protoboxes. As I was making the spool valves for my "Dancer's Engine", I found some material in my brass section that didn't look like normal brass. I know it came from one of the Protoboxes I've purchased. It was much more difficult to...

    When a CNC motor coupling goes bye-bye

    I was using my CNC'd Mini-Mill for machining a walking beam for an engine to which I'm making. Near the end of the NC program, the Y-axis motor coupling snapped. Losing an axis on a three axis system isn't good. The mill then promptly decided to mill right through the beam web. Ugh.... I...

    Vederstein's Dancer Engine Build

    In the Plans section, you'll find some musings on my version of a water pumping steam engine located at the London Museum of Water and Steam (a.k.a. the Kew Bridge Steam Museum). Being that this engine has a some components where the techniques are new me, I felt I'd share my learning...

    Ved's Dancer's End Engine

    In 2013 my wife and I vacationed in England. One of our stops was a the London Museum of Water and Steam. All the engines there are either part of the original water works the place used to be or engines brought in from other locations that were used for pumping water. One of the "imported"...

    When This Hobby Actually Becomes Useful

    In this hobby we make expensive toys. Unless your engine is going to be some type of teaching tool, the end result is a piece that will sit on a shelf and collect dust. Sometimes, just sometimes, I actually use these skills I've developed making toys on something useful. I have this project...

    Four Square Engine Plans

    This is a continuation of the "Un-Named Engine" thread. I've since actually named this thing "Four Square". As promised, here's the plans. I highly suggest you read up on the Un-Named Engine thread. This design requires significant air pressure to run because of the engine geometry. It...

    Un-Named Engine

    On to the next idea for my series of "steam" engines with strange layouts. I notices on my last project, that back-driving the valve cam resulted in shaft rotation that wasn't too hard. Therefore I think I can have an engine using an offset circular cam instead of a crankshaft. I could've...

    Swashplate Engine

    After putting in too much time designing a stationary engine using Walscheart's valve gear, I was never able to get it looking like I had envisioned. So, I dropped the idea for now and went back to an idea I started years ago: An axial engine using a swashplate as the crankshaft. Looking on...

    Walschaerts Mechanism

    I've always been fascinated by the valve gear of the later steam locomotives. The fact that is works with only levers and no eccentric is amazing to me. A little bit of research and I found the mechanism was originally designed by Belgian Egide Walschaerts in 1844. (Wikipedia page here.) Over...

    T-Head Engine Plans

    Ok, For me, this engine was a failure. I just couldn't get the valves to seal worth a damn. I don't necessarily think it's in the design, I think it's because I suck., So in the following few posts, I present the design for this four stroke engine. If anybody tackles this thing and is...

    Modified Coomber Rotary Steam Engine

    I put on a coat of paint on my Modified Coomber steam engine. You can find the plans and CAD models here: https://www.homemodelenginemachinist.com/threads/coomber-engine-ideas.32117/ Here's the finished engine:

    Engine Valves

    I've done enough Steam and Stirling engines that I think I'm going to try my hand at a four stroke gas engine again. My first experience was a Webster where I failed to get the thing running. My question revolves around valves. Why always poppet valves? I had a hell of a time getting the...

    Coomber Engine Ideas

    On to my next engine. I was looking at Elmer's #46. The Coomber engine. (I don't know if it's "Coomber" or "Comber". I've seen it spelled both ways.) Anyway, these designs always have the cam ring with the cam rollers on the inside. I was thinking what would happen if I put the cam rollers...

    V-8 Engine & 5 Speed Gearbox in Kerbal Space Program

    I don't know how many here are aware of the computer game Kerbal Space Program. It's a rocketry and orbital simulation game. Some people have made some amazing non-rocket related items using the physics engine in this game. I came across this one what really blew me away. He modeled a V-8...

    Gaging the market - Casting for the Sun-Planet Engine for Sale

    This is the first time I've made this offer. My sun-planet engine came out so well that I think I'll offer to do a run of the one casting that unavailable anywhere else for this engine. If I get somewhere between four and eight people to commit to buying one, I'll do a short run. The other...

    Sun-Planet Engine - Finished

    I've finished my Sun and Planet engine. Given that I didn't know if this would even work when I started, I think it turned out ok. Plans with 3D sold models are freely available on this website in the Plans section of the forum. ...Ved.
