Hello Richard!
Thanks for the comments, glad you liked it. I do not have an oil cooler on it yet, so far it's not been needed. I am looking at making a geared electric starter, it has to turn 20,000+ rpm to start the engine. even most series wound motors start running into problems at that speed.

rigt about that, Ward! cant you start it with a scramjet feeding into the
hot part of the turbo?with an extra manifold or so?? the expanding gasses wil bring the fan rotating that fast?
Maby new project???(LOL!)
hope to see it on you tube when it runs again!

Good job sir! I built one based on an VT50 turbo
last year and placed it in a garden tractor.

U can tell by the look on his face that he is very excited about his work..... and he should b he has built a great machine.
Congrats and hope 2 see it mounted on somethin small soon so u can drive it.
have you considered ... ( 1 year ago by highrevs2792)
have you considered using a dremel tool motor for a starting device? they can spin 30,000rom
What are you using ... ( 1 year ago by XiD07X)
What are you using to measure rpm?
Hello highrevs2792! ... ( 1 year ago by Jetpropelled)
Hello highrevs2792!
I am looking to gear up a 12V motor to start it so I can start on the 12V battery that runs the lube pump.
That way I am not tied to a plug in. Dremels have
good rpm, but the torque is lower. I have not tried
one but I doubt that it would spin the wheels fast enough to start. The IR die grinder I use has 1/3 hp.

Hello XiD07X!
I am a mechanic by trade, my brother is an electronics
engineer. He built me a digital tachometer for the engine. There is a laser pointed at the blades of the compressor wheel. A photo transistor picks up a flash every time a blade goes by. count the flashes, divide by 7 (7 blades on the wheel) and put it on a display.
On a cold start, idle is 22,000 rpm or so.
once it's warmed up about 19,000 rpm.
fasted run to date: 68,500 rpm. Yes it sounds SWEET!!!

thanks for the ... ( 1 year ago by highrevs2792)
thanks for the response ward! another seemingly popular idea for start up is the leaf blower method but then again its not geared in with push button start. the dremel also needs 120v to make power so it wont likely pack much of a punch on 12v. God bless you and good luck,
matt.

I am impressed. Do you have any idea how much thrust is produced? Also, how long will the turbine bearings last? How do they get lubricated?
You should add ... ( 1 year ago by mateo9944)
You should add another set of compressor blades and use them to drive the wheels of a go-kart or the prop on a small boat. You will end up using more of the jet's power that way.

Verry nice jet engine Ward! Isn't this a very big risk you take with such a machine? What happens when it goes wrong ?

So far it's only caught fire once, It's not by accident that I run it outside!

Nice engine! Looks like your afterburner flame blows out easily. If you havent already done so, constructing a flame holder where you inject the afterburner fuel would help! Really simple, just an obstruction in the airstream at the injector that collects turbulence behind it. That way the flame has somewhere to propogate inside the nozzle before being blown out. That will give you the full, screaming flame at the nozzle exit.

Lol that is so cool..i wish i could hang around these southern folks --i could learn so much from them. How many ppl do u know can be so crafty and make their own jet motor? Props man

Sir how much thrust does it pull?? Once again, nice engine. Interesting that it is diesel powered

Hey was wondering what the tube coming out of the top of the engine was used for is it some kind of expansion chamber or something.
combustion chamber. ... ( 10 months ago by justinbimmerman)
combustion chamber. the fuel and air mix in a flame tube inside of that and a spark ignites it. the heat expands the air spining the turbine. That tube is where the power is made :)

Tips to help you create better videos

1. Eye Candy.
Think about some of your favorite videos, ask yourself, what interesting shots and b-roll need to be captured to make your video entertaining to watch.

2. Good Lighting.
The main difference between amateur and professional videos is the quality of the lighting. Poor lighting creates graininess and poor quality videos too. (*Hint* In most studios, the lights and the cameras can be adjusted up and down to get the correct amount of light.) For your home studio make use of fluorescent light bulbs. These bulbs produce a nice soft light with no harsh shadows. You can buy fluorescent light kits or you can save a lot of money and make your own fluorescent light box. It is best to use a three point lighting system which is fairly standard in most studios.

3. Tripod.
Use a tripod for shake free shooting. Tripods come in all sizes and quality. Most camcorders used today are only small and weigh very little so there is no need to buy a tripod to suit a heavy professional video camera.

4. Microphone.
The built in microphone on your camcorder is not the best to use if you can avoid it. Buy a directional one that can be mounted on top of your camcorder. Otherwise mount the microphone on a boom or support just out of view of the camcorder but close to the subject. Another option is to use a microphone that clips onto your lapel and as used by newsreaders on television. These are very effective and can be purchased for less than $50. No need to buy a wireless unit, but you need enough cable to run from the camcorder remote microphone, up the inside of your shirt and to your lapel. Bear in mind that you will normally be seated within six feet of the camcorder so the microphone should have plenty of cable.

5. Avoid Zooming and Panning.
Avoid zooming in and out and panning from side to side as much as possible. It is recommended that you set the zoom prior to recording.

6. Pre-Roll and Post-Roll.
Allow a few extra seconds after starting and before stopping the camcorder and the actual start and finish of the action you want to record. This allows for better editing once the shooting is over. Not allowing for the pre-roll and post-roll can make editing difficult. If you are filming yourself then start the camcorder recording with the remote control, wait six seconds before you start talking and at the end let the camcorder run an extra six seconds before stopping. This will give you plenty of time when editing.

7. Remember It is A Small Screen.
When shooting videos to add to your web site, normally the player will be 320 x 240 so avoid wide scenes, keep it close to see the detail. If you are filming yourself talking, you should be within six feet of the camera and preferably from the waist up. Keep the content simple and uncomplicated, do not have much happening in the video and keep it quiet-on-the-set.

8. Think Like a Photographer.
When shooting a video, do it like a photographer taking individual shots. Plan your video shoot, record for a short while from one position then stop recording, reposition the camera or yourself then shoot again. This will reduce excessive camera movement in your video. Using these tips will ensure that you can shoot and produce quality website videos of a better quality than most people. Remember, practice makes perfect and soon you will be getting great results on the first take.

9. Look at the Details.
Sometimes, you are so focused on your subject that you do not notice the surrounding elements of the scene. Only later, when you are reviewing the footage do you notice an unsightly trash can in the background or a tree sticking out of your subjects head. I like to scan the video screen carefully before shooting to make sure there is nothing in the shot that I may have overlooked. You may be surprised what you find!

Use our search feature, at the top of the page, to find videos about your favorite topics. There are tons of videos, for example, type in "Bikini contest", "Body building", "Guitar lesson", or "How to (anything)". Search for "Commercial", you will see cool ads and funny commercials. Notice the video techniques used to capture each video, you may very well find many helpful tips and tricks to use as well as many techniques to avoid when making your own videos... have fun.
