Simple Steam Engine

In this instruction, I will explain to you how to creat simple steam engine.

At first, you need to make valve gear. I made it out of wood but it should be enough heavy.

Flywheel's diameter should be same to lenght of a piston in engine.

Last part of valve gear are two sticks that spin around their connection.

From brass pipe you need to cut four rings and make from them six details which are shown on second image. Details in form of Г probably will be needed in step 9.

To attach engine to some thing in future you need put on the trunk a cork bung.

To fix cork bung on the trunk you need cut two circle from a can and two details from step 4.

For piston you need one solid metal stick and plastic circles. In one circle you to make a hole and in other a hollow. Than you need to smash one end of the stick and glue plastic circles on it, how is shown on second image. After you need to glue circle from a skin to make it hermetic inside of the trunk. Also you need to know size of piston for future step.

On this step you need to cut one circle from a can, like in step 6, but now with diameter of the trunk.To connect details together firstly you need cover them with a solder.

I recommend to put piston inside of the trunk before soldering. Also because metal ring soldered with the trunk we do not need details from step 4.

You also need to add two loops on sides of the trunk to tie a rubber rope to them. The rubber rope will return piston back after steam pushed it out.

You can connect piston to the stick from the valve gear in you own way it need also two loops.

Now you need to drill a hole for steam release, using measurements from step 7. I used a balloon to find how hermetic is the engine. Than you need tie rubbers to loops.

I used pencil to push the piston and test the steam engine.

Thanks for reading my instruction and good luck in the work.
