Non-machined oscilating

[IgorWojas]

Since my will to create engines is great, i menaged to build one without using ANY machinery except hand drill. I don't have any lathe, milling machine or whatever else you guys have in your workshops. I want to buy a mini lathe and milling machine soon, but I don't have enough money.
The engine was made completly without any plans, just the one i've had in my head It took about 2 weeks to make it run. But now its dead, the inlet pipe is broken, and i don't have any time to fix that right now. When (and IF) i repair it, i'll record a short clip of it running, to show you

EDIT: I forgot to tell you the fun part The cylinder is made of an aluminium pipe wit a bb bullet glued inside it, flywheel is basically a LEGO wheel, main shaft is made out od a drilling rod, and the crank is another lego part... well as you can see, i try to use everything that's in my reach. Comments please.

Good work!, it just goes to show what you can do with a little imagination and almost no tools!
