Heh heh , there always seems to be so much to do when we start a new build, I tend to not look too far "down the road" , just concentrate on one small task at a time, otherwise the job looks insurmountable.
I like to start at the compressor end , so much easier to make the bits from alloy rather than the hot end stainless .
You'll get there with us encouraging you all the way :-)

Hi All,
My name is Steve Peterson, I live in the San Francisco, California area, and I'm a software guy who's into rockets. Designed, built, flown many small-ish solid propellant rockets, and I'm now taking the first few steps toward designing, building and flying a liquid one.
Unlike many here, I'm not at all a machinist. I have a 9x30 lathe, drill press and band saw, plus some decent woodworking stuff (e.g., table saw). The lathe mostly gets used for nozzles and drilling radial holes in tubes, although I've done some light milling of mild steel on the lathe--good enough to make some quick change tool holders. At this point I'm set up so that I can do all the lathework and milling I'll need to do for a liquid motor.
What I *love* to do, however, is research and write software--between that and my practical experience with solid rockets, I believe I can contribute a bit here and there to the threads in the rocket forum. Hopefully before someone gets hurt.
--Steve

Hi Steve! Its great to see another person who dabbles in computer witchcraft. What kinds of software do you write?

Richard: Professionally, my software has tended to be "backend" server-type stuff in the area of databases and internet services. "For fun" these days is pretty much rocket-related including a flight computer that handles altitude measurement, gps tracking, and transmission of data to a hand-held receiver on the ground. That's all microcontroller (PIC) stuff written in 8-bit assembler (electronics is yet another hobby). I also have some rocket design software that runs on the desktop, written in Java.
Grant: Blackrock desert in Nevada. Seven hours each way, so I don't fly that often.

Very nice I guess you are the guy to talk to about database stuff then. SQL drives me bonkers. |

Richard,
Sure, PM me any time--I'm happy to share what I know. I tended to keep my SQL pretty simple (no inner joins with "connect by" clauses :-)) just so I could understand what I wrote a few weeks after I wrote it!

Steve, if you've ever turned the lathe on and made some chips/turnings, then you're a machinist. A crappy one but you're one. I'm a little better than crappy as i hate using measuring tools (can't find them) and I spend hours creeping up on sizes and hours doing it over from when I cut off just a little too much...

Chris: Then I stand corrected: I am a crappy machinist :-)
Actually, I usually work to about 5 thou, sometimes as close as 2 thou. Most of my work just isn't super-critical. Thankfully, O-rings, even at 1000 psi, seem to tolerate slop pretty well. I have nothing but awe and admiration for those who make things to very tight tolerances.

Hey everyone,
My name is Will and I heard about your forum by talking to a guy who has been building turbojets and putting videos on YouTube (HighVoltageFeathers is his username).
I have been an aspiring turbojet builder for about a year now but have only just looked in the mirror and said "lets go." My plan is to build it over this summer while I am home from college. I have watched every video there is on YouTube about the topic but would love some experienced advice (particularly around building the combustion chamber/flame tube so it doesnt burn up the exhaust turbines).
I am going to familiarize myself with your site and some of the threads before I ask any obvious questions. From what I see, you are a very welcoming community and I look forward to learning from all of you
--Will

Will, glad you could make it. kartkid is my username on JATO, highvoltagefeathers was too long  . What do you have access to as far as tooling and welding equipment? |
