It couldn't be simpler!

Here's an ultra-simple way to build a pulsejet engine without using a lathe, milling machine, welder, or any other expensive machinery. In fact, all you'll need are the tools shown in this picture, somewhere to work, and a bench- vise. A drill (electric prefered) with a set of drill bits

A hacksaw

A screwdriver

A hammer

A file

Some scissors or metal snips

A tape-measure or ruler

A black felt marker

A center-punch

Some muffler sealant paste Using these simple tools, you can convert this pile of metal into your own pulsejet engine. The materials consist of: Some 0.060" to 0.010" spring steel or shim steel.

a length of steel or stainless-steel tubing.

a cheap stainless steel drink flask

a length of scrap aluminum bar

4 x self-tapping screws

4 x small bolts

a short length of copper tubing

a hose-clip (jubilee clip) And the result is this engine which is capable of several pounds of thrust and, if built with thin enough tubing, is light enough for use on model boats, planes or cars. An abridged set of instructions for this project will be uploaded to the website shortly. The full step-by-step set of comprehensive instructions are already on my CDROM -- which includes a VCD-quality video showing the entire construction sequence with plenty of tips and advice.
