Ok since the fuel jet forum has moved to its new home, I thought I'd see if anyone was interested in a build your own turbine discussion. It's been awhile since I started this thread and maybe someone out there who is new to RCG can chime in too...
Later,

Hey mcjustis, first i have to say GREAT freakin' job!
And, second off, I have been trying to build a homemade jet engine for a while now.
I am well on my way in doing so.
My only problem was getting compressors, but the fact that you said you used a turbocharger compressor has given me an idea.
I will keep you updated on my progress.
I would love to hear more about your engine though too.


P.S. have you built a turbocharger jet engine also.
A friend and I have embarked on a new journey in doing so, after a friend of mine's father made one that produced almost 300 pounds of thrust.... It has given me inspiration also.
I will keep you updated on that progress of the turbocharger jet engine also.

Ron,
I had just about given up on there being anyone interested in my posts here. It's been several months since anyone posted on this. It's good to see someone out there isn't brain dead. I would love to give you any help I can. If you can't find a compressor in junk yard, you can buy them pretty cheap anymore. Whatever size you can find I'd get it. They are pretty much all the same, they all use the same ratios and just size everything to the compressor. Don't let anyone tell you that they can't be made well. They absolutely can. My only stumbling block is the cash for a plane. I think I might just build from plans and save some cash. I think my wife would kill me if she cought me starting another plane anyway. Don't listen to people who don't have a clue, I actaully had some clown tell me NOBODY in the world can make a turbine that works, some people are just braindead. Anyway, keep us posted on your progress...later.

Hey mcjustis, there aren't any junkyards around here, so I have a problem with finding them.
P.S. where are you located?

Located in Columbus Indiana. I was born in Baltimore though. Don't know where Damascus MD is???

I can find the number of a guy somewhere who sells all type of turbo stuff. You might check ebay also. Sometimes in the auto parts you can find one. Like I said also don't worry about the size of it. You can size everything else from just the compressor. That's what I did.
Later...

Yeah, Damascus is about 20-30 minutes from Baltimore.
Right about in the middle of DC and Baltimore.

Ron, I just checked the size of that one. It's 65mm. It would probably be a good one to work with. Also the ones from a turbo are already balanced. By the way, what do you have in the way of machinery? Basically you need a mill, lathe, bench grinder, die grinder, a tig welder, and small hand tools. You may have to fashion some jigs and will definitely need to make a balancer. So what do you have done on the one you're making? Later...

I have a lathe, a tig, and a bench grinder at the moment.
On the jet engine I have started the outer shell and fire holder cup.
As soon as the compressor comes I will buckle down and start the real building process.

What kind of setup are you using on the combustion chanber??? Are you going from a book or looking at another engine? There is a method to them and they need to be done correctly to work properly. If you want some good info check out Thomas Kamps book


http://www.amazon.com/gp/product/095...lance&n=283155


It's a good book and you can pretty much build straight from his plans. Kurt Schreckling has a few good books, they are good for the theory and to see how they work, but I wouldn't build his FD3/64. VERY old outdated thing.
Let's see some pics of what you have. Also how big is the combustion chamber you have going. Do you have vaporizor tubes in, fuel ring???

Na bro, nothing but the casing and fire holding cup so far.
I am working on the turbocharger jet engine more than the small one.
I will take your advice and get that book from the local borders.
So far I have been looking at other engines to get some ideas.

Wow MCJUSTIS!
I am impressed! I just bought RC Turbine Jets & Helicopter and was blown away by the jets being made today. I have been interested in building a jet engine for the longest time, but after reading 5bears website a few years ago, I was discouraged. I didn't think I could build one with my lowly Sherline mill and lathe. And now I see what you have done! I am inspired!
Thanks!
