Building Miniature Engines

Our manual, How To Build 4 Miniature Engines, presents the fully detailed plans, photos and drawings for building each of these outstanding engines in your home shop. The plans and prints available were mostly drawn by community college CAD students……not surprisingly, some are better than others but (in our opinion) most are sufficiently good enough to be used for construction purposes……there may be minor errors here and there……I think we’ve caught most of the inconsistencies but, just in case, look them over before you start cutting metal.

I am most impressed with Jan’s take on two stroke engine design and I feel my difficulties are due more to my construction than to Jan’s design. Buy All These Plans on CD: Every plan on the site, delivered to you on CD. Just 19.99! As MECA grew, a Swap Sheet for engines and parts exchanges was instituted, Collectos” (engine collectogethers) began and national Collectos, now called EXPOs, started. The design and manufacture of engines involved hundreds and I can’t mention them all.

If you would like a Challenger V8 built for you or any Challenger V8 parts fabricated for you please contact us for pricing and availability information. It won’t be something that is going to work daily – this engine is going to run once or twice. Once completed, the engine will be displayed along with a credit list noting the names of all who participated. The Hicks heavy-duty marine engine was less likely to foul from moisture and was thus extremely reliable (Prine, 2010). The ‘glitzy’ spark plug cap supplied with the CDI unit was replaced and the HT lead screening was run to earth under the engine base.

Full Details and complete plans and photographs are available for free download on my website – www. Some parts inside the engines are made to scale like the 30-30 Duntov camshaft, but some things have to be modified to make a small engine run. It is often the case that the plans published in Model Engineer are actually more complete than the original plans published when the kit was designed, and the comments from the builder can be most helpful in finding and fixing problem areas before you get to them. Thanks guys, I am really interested in something like the Tiny Power Ajax Engine.

The internet has many good sources of information on small IC (internal combustion) engines, Stirling engines, small turbines, and other alternative power plants; we haven’t addressed any of those here. Getting a small engine to run requires skill and careful work; getting one to run well is an art. One bonus of the switch to CDI ignition is that with the coil and larger battery dispensed with, a shallower base is now practical and this, in my opinion, results in a more pleasing overall look to the engine. Pirker 4-Cylinder Engine: An interesting modern 4 cylinder wobbler valve steam engine design.

Elmer Verberg’s Geared Engine: Elmer’s Geared engine is an unusual design but once in use in the factories of the industrial revolution. Elmer Verberg’s Open Twin Engine: Elmer’s open column twin cylinder engine is a variant of a poppet valve engine originally designed in 1913. Showing you how to make a homemade steam engine; be it a single or double acting, single or multiple cylinders, easy or complicated, whatever you are looking for in a live steam project.

In the pictures though, you can see I replaced the spring with a small elastic band that goes around the whole steam engine. I made a start by building the engine base plate and crankshaft bearing supports. Later in the year, Brown gave Grant his last hand-built Brown A. Installed in the KG-2 (a modified KG-1), the airplane and engine set many records.miniature engine plans

The Compound Launch is designed to be more efficient than the Twin Launch, in that steam is only supplied to the small cylinder and the exhaust steam from that cylinder then travels to the large cylinder. American modelers found the diesels didn’t match the performance of glow engines and diesels never became popular, although Leon Shulman’s1948 Drone diesel saw a fair amount of use. Plans for a Russian Designed Pulse Jet – This is a scaled down version of a large pulse jet designed with model flight in mind.

Elmer Verberg’s Horizontal Engine: Elmer’s horizontal engine is a simple double-acting engine of the type comminly used in mills for grinding grain a hundred years or more ago. Tim and Betty Dannels also publish the American Model Engine Encyclopedia (AMEEI), a fine source of identifying engines with sharp photos and descriptions. Its a while since I checked, but there used to be Yahoo Groups with many, many engine designs available free from old Model Engineer magazines. A top view of the engine shows the stinger exhaust pipe Tom designed and turned from aluminum.

This fully functional miniature jet is not a toy and creates considerable thrust. So I started by making some of the steam pipes, CNC’d the flanges, and silver soldered them. First one was from a plan found in a little book that had been given to me by a friend who built steam tractors and locomotives. Simply stated, the steam engine is a great tool for explaining many complex engineering principles and theories. Engine production accelerated in subsequent years and engines were being produced across the country.

I accidentally damaged a gunmetal casting (an end plate of the condenser unit) of my triple expansion engine. But multiply that by ten, and you’d still fall short of the challenge this hobbyist faced when he set out to build a fully functional miniature W32 engine from scratch. Craig was on vacation during that time, but upon his return Tom fired the engine up for this video. I am keeping my fingers crossed that the same modification will produce a similar result for my own engine.

Grizzly currently offers the plans and instructions as a free download, and they sell all the metal stock as a kit for a very reasonable price. I opted for Jan Ridders ‘Debbie’, a simple two stroke to a design where Jan has removed as many of the difficult bits as possible. Ezilathe” is a free program (currently), works brilliantly, and was written by my friend Stuart.

Jim Larsen’s innovative approach to Stirling engine design helps you achieve success while keeping costs low. There are detailed plans to build 9 engines of different types and complexities in this series of articles. Now fliers wanted stronger engines and K&B answered in 1959 with a45 RC engine that coupled and exhaust valve with a rotary choke carburetor.miniature engine plans

Jingle Bell Engine: The Jingle Bell is a mostly aluminum demonstrator using a wobble plate valve design. Following a suggestion from my mentor Bogs I modified the design to a square edge ball seat rather than a taper and this certainly improved the sealing properties. Above: One of the world’s smallest 4-cycle piston engines, but able to drive a wide variety of miniature vehicles that require considerable power. The rotation of the engine is slightly irregular because only 2 of the cylinders are powered, but it is still a mightily impressive sight.
