Building a jet turbine engine on a shoe string budget

This is the second video to my flight of fancy. I have no real intentions of ever building a jet engine any time soon, but I do have a number of machine shop tools and shop skills and a love of metal working. When I was a small kid, I used a tuna fish can as a piston and couple pieces of copper tubing for a piston rod. I got stuck with the whole internal combustion engine concept after I built the piston and piston rod. I needed an exact diameter tin can for a matching cylinder to my tuna can, which I never found, before I really could go any further with the construction of my engine. My friend that was a year younger than I, he was impressed and asked several times when I was going to complete the engine. I told my friend I was going to power a Go-kart with it. My tuna can engine sure looked neat and the tuna can engine sure looked like it had intentions of actually being something at some point. Even as a kid, I knew my chances of being successful at this project was at about zero. The tuna can ended up being more of a kenetic sculpture for a couple years before getting tossed. Oh well! My imagination has always been very large. Just to show you can make a jet turbine from scratch, here is an exploded view of a model jet engine from 'Gas Turbine Engines for Model Aircraft, By Kurt Schrecklin' Copyrighted Traplet Publication. The cleaner looking engine pictured in the video is the FD3/67 LS. It is a kit of parts. The jet turbine and parts brought up from scratch in the video appears a little less polished and the rough welds show the turbine wheel. The compressor wheel is actually made from plywood to save weight and the outer rim of it is wound with carbon graphite cord for strength so it doesn't blow apart at high RPM. Since the compressor wheel is not in the hot part of the engine it can be made from wood.

dude,realy it work?

[GregoryLog]

The author of the book suggests it does. He has built several I never made this engine so I will take the word of the author of the book this jet engine works.

Hay nice but when are you going to ad my vid resons i am happy to ad yours as i did but i exspect th same curtisy

[GregoryLog]

JoelHarvey1, I know you requested a video response to "Building a Jet........ Shoe String Budget." I got an e-mail in my Yahoo account alerting me to it, but when I went to my YouTube account I could not find a way to add it. You sent a request twice and each time I went looking in my YouTube account I couldn't find a way to add your video. I did put this video as a video response to your video "Joe Harvey's Home made Turbo Charger Gas Turbine Jet Engine" Resend a request maybe It'll work

My other thought there might be some government entity that doesn't like such information dispensed so freely. I suppose if you attached a warhead and a small set of wings to a jet engine like this you'd have something similar to a V1-Flying Bomb minus the most primitive of a guidance system and you'd have a very small warhead capacity. Such a weapon would be a terror weapon more than a tactical weapon. Some big users of poorly guided missiles were Iraq and also the Palestinians.

Be sure to check out YouTuber ' thewebmaster93 ' He is currently constructing a turbine engine. It should be fun to see his completed project.

@heshamez

i havent red the the book thoroughly but im 100% sure it does, i downloaded it mostly for the plans.

[heshamez]

does the book include the theory of work of jet engine ?

[heshamez]

does the book include the theory of jet engines work?

,,what is a shoe string budget?

[stdavross666]

@lexichronicle2 The guy is from New Zealand not the US

[lexichronicle2]

@GregoryLog Nah, these things are easy enough to buy and designing them isn't that hard.

Terrorists hate complicated things, they love jam jars full of nails and explosives or other ultra simple stuff.

However, there was a guy in the US who tried using such an engine to build a small cruise missile, a GPS for guidance. He specifically stated it was to 'demonstrate how easy it was'. I believe the police did take the DIY missile off him.

if anyone needs this book i can send a pdf file. just pm me

I had always wanted to order the plans for the "Screaming Demon" gas tubine from the adds in the back of popular mechanics since I was a boy. I finally did and got them here. They only give you partial instructions. You still have to design for yourself the oil system, the fuel pump and nozzel, the shaft bearings, and a bunch of stuff. I have the machines and skills, but no time.
