Default Free plans for a larger, simpler, beam engine

I love Elmers engines, and I love the concept of all the moving mechanisms on a beam type engine.--That being said, after building one of Elmers basic wobblers, I find them, well,--tiny!!! They work, and they work very well, but for new amateur machinists like myself, its almost micro machining. I want a beam engine that is larger, and somewhat simpler to build, and one for which a kit is not needed. I want the parts to be large enough that I can machine them without a magnifying glass, and I want all the parts to be made from bar stock. So--I have taken Elmers beam engine, scaled it up to twice the size Elmer had in mind, and I am doing up a complete set of plans which I will post here. Many of the peices will be simplified, and if someone wants to take any of the parts and fancy them up a bit, that is perfectly fine with me. Stick around, and as I get the plans completed, they will be posted here with full dimensions and material specifications.--Brian

Brian,
Good for you, excellent idea! I am in the same frame of mind. I dislike running a tap into metal and trying to imagine that I'm cutting threads (like 2-56). I just did a 1.5x scaleup of a Ray HasBrouck design but I won't post my plans since he's still selling them. But it was a straightforward scaleup - just multiply everything by 1.5x and improvise when necessary. I'm looking forward to your results.

Cheers,
Phil

Definately a work in progress as we speak. I'm on holidays and its rained all damn week!!! Might as well do something I enjoy--(you'd think I would get enough design work the other 50 weeks of the year). I love this 3D software (Solidworks) and steam engines, so---

If anyone wants Elmer's Beam scaled up by about 1.75x and converted to metric I can supply the plans (I haven't got round to building it yet though!).

Can someone tell me what the advantage of the beam is? I never understood why the beam was used. Why not just connect the piston to the crank with a connecting rod - you have to connect the beam with a connecting rod. Please educate me?

The beam type engines didn't originally turn a wheel. Instead of a wheel, the end of the beam was connected to a plunger in a pipe that pumped water out of the coal mines in Wales. I expect that the wheel was added at a later stage to get rotary motion, as the design of steam engines evolved. Eventually, somebody had the same thought you did, and the beam was done away with.

Watt's original engine was a beam style mine pump.

That would be great. i have been considering this engine for some time.

Kind regards
