How to Make a Steam Engine with Pictures

Be very careful not to get any on the outside of the piston, also try to keep the tube pressed to the table so no epoxy will get out under the edges of the plastic wrap. Next take a small piece of plastic wrap and cover one end of the piston tube, secure it with an elastic. Our cover story this issue is about a central South Island marine engineer sheddie who really is living the dream. The fuel used is methylated spirit and a suitable burner needs to be constructed. Methylated spirit does not necessarily need a wick but the fuel efficiency can be greatly enhanced by using wicks. Wick mate-rial is easily available from camping shops and most hardware stores.
I should note that this animation is of a "double acting" engine, in that is has ports on both the bottom and the top of the cylinder where mine is a "single acting" engine with ports just on the top. This just means that the engine relies more heavily on the momentum of the flywheel to keep it running but is a lot simpler to build. I should also note that even if you did build a boiler this engine probably wouldn't work well because many of it's major components are wood. In the presence of steam the wood would swell and warp causing problems.

The boiler used in this model is constructed from a 100 mm length of 50 mm diameter copper pipe. This is the type of pipe that is used for sink wastes in older houses. You could use 40 mm copper if you can’t get 50 mm but just make it a tad longer to accommodate sufficient water. This model was made from a piece cut from an old waste trap which had been replaced by a new plastic one. This is still reasonably easy to obtain in short lengths from plumbers who have off-cuts that they may be prepared to sell.
Use metallic tape to secure the tubing from the bottom cork to the tubing extending from the bottom of the copper coil. Then, secure the tubing from the upper cork to the tubing extending from the top of the coil in the same way. Epoxy the cylinder head to the cylinder then both of those to the 'cylinder back' so that they are centered horizontally and the bottom of the cylinder is aligned with the bottom of the cylinder back.
Step 7: Crankshaft
If the piston becomes stuck for some reason, pressure can build up inside the small can. In a worst case scenario, this can cause the can to explode, which can be very dangerous. Start by drilling out the 12mm hole in the cylinder head before you cut out the square around it, unless you have a drill press such a large hole will be hard to align with a small piece of wood. Now cut out the 2.5mm deep grove in the other Cylinder Head part. I used the wire from one of those little red flags you see stuck in lawns to mark the sprinkler system. This size of wire is excellent because it fits perfectly inside of the plastic tube that Q-Tips are made of.
As Dave says you should be fine with ali/brass, I have quite a few ali pistons running in bronze cylinders so similar situation and no problems with them. The plans go on about soldering a tube etc, I'd rather just insert a threaded fitting to accept a small airline. I decided to omit mounting holes for the cylinder at this point as I'm not yet certain how I'll go about it but will probably deviate from the plan. The plans are in imperial but I've decided to work in metric so whilst I am working to the basic design the measurements are flexible and I'll modify / embellish it as I go along. If you must handle the engine while it is in use, do not point the ends of the tubing toward anyone, as hot steam or water could cause scalding.

As you bend it, work hardening will take place so you may have to repeat the process. The copper tubing is best cleaned with steel wool and then polished with brasso. Brass nipple connectors could also be used on the engine stand but I think it is unnecessary. Try to keep all pipe work vertical or horizontal in elevation and all changes of angle made in the plan view.
The secret to the steam engines success was its immense source of power. Any fuel that could be used to create heat and convert water into steam, could be used to power a steam engine. It is this quality that allows us to continue to produce most of our power with modern steam turbines. Anything from oil to nuclear power can be used to turn water to steam and generate electric power. For this reason, we will likely never see the end of the age of steam.

This gives the piston rod a little more clearance and prevents it from creating more friction rubbing on the crankshaft. To build the cylinder block start by taking the wooden part "Cylinder Back" and sanding down the center gray area of it by about 1mm. This will make a smaller contact area between it and the body, thus reducing friction. The boiler construction is covered first and then the engine. I decided I wanted to bottom mount the cylinder block and reasoned the only way was to face off in the way others had suggested, with the intention of bolting it to a plate.
This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work. Once sufficient pressure has been released, the piston will be pulled back down by gravity. Trim pieces off of the skewer as needed to reduce the weight of the piston - the lighter it is, the more frequently it will "pop" up. Try to whittle the skewer down to a weight such that the piston "runs" at a constant clip.You can speed up the burning process by using a hair dryer to blow through the ventilation holes. Crumple up pieces of newspaper and place them in the space enclosed by mesh at the bottom of the engine.
This was probably due to the exorbitant cost of the product rather than any regard for safety. In this video, how I successfully completed my steam Engine Project. A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder.
Thomas Newcomen, however, became the first inventor to harness the power of steam with a piston driven engine in 1712. Known as the “atmospheric engine”, it utilized the condensation of steam to create a vacuum driven power stroke. Steam soon began to replace the water wheel, allowing factories to be built far away from rivers. It was this expansion that helped drive the Industrial Revolution. The end plates can be made from the same material if it is annealed and cut to shape and then flattened. They can also be made using a former, to produce slightly domed end plates.
They are also very quiet compared to the usual Aldi/Lidl 2 HP or bigger versions they sell from time to time. Drilled through as far as power cylinder, I was a bit relieved at this point. With my limited tools and experience I wasn't certain how parallel the bores were etc. However once the inlet was drilled through my scriber seems to suggest they are reasonably true. Steam chest bore done, I decided to make this slightly larger diameter than the plans as I think that may prove more forgiving at my skill level. Do not attempt to build a more complex steam engine with a boiler unless you thoroughly understand how to do so.
