Go Ahead And Blame Your Family

Yeah Thomas, its your family that is causing all your problems. My family caused me a lot of grief too, that's why I moved out to the country to live alone in a cottage with a dog. I like the internet because it allows me to socialize without actually having to visit anybody, or have anybody visit m...

Forum Magic

Some forums allow you to delete your posts, while others only allow you to edit. In my case, I can delete in all forums except the Off-Topic, where I can only edit. You can open 'edit' and then just delete all the text in your post, Mike. I did that once.

Never Heard Of That

I doubt many affordable AC motors have built-in inverters. Even if a motor had an inverter and you removed it, you would still be left with an AC machine. You could run an AC motor from a DC supply by spinning and exciting an alternator field with a DC motor and supply and then using the alternating...

Oh Yeah

The on-board compressed air was also used to pressurize the fuel flow.

Launching Your Buzz Bomb

I have read in many places that compressed air was used for starting the V-1. There were ports on the back of the valve grid for admitting it to the combustion chamber from external tanks. The internal tanks were used for running the gyros and also for operating the control surfaces too I think. The...

Somebody Should Write Some Monologues About This

The Hirsch-Ranke Vortex tube is a fascinating device and much discussion thereof can be found in the old forums. I had one idea in particular for its use as air conditioning in semi-trailer trucks but nobody seemed to find it of any merit. Do you have a video of your new engine in operation? It look...

Better Than Anthrax

Well if you went to Canada411.com to get my address, they got it wrong there. The municipality and postal code are wrong. I get my mail general delivery out here anyway, so only the post-mistress will suffer from your twisted scheme. Nice try though. Good luck in the future.

You Want Me To Sit WHERE?

I question the wisdom of placing the driver right at the very front of this land-speed-record-breaking vehicle. Practically every other ground vehicle ever designed has a lot of metal between the cockpit and the front bumper. I don't think that pitot tube will be much help in the event of a superson...

Sponges, Timers, and Un-Necessary Fluidic Emmisions

I like this sintered hi-temp fuel sponge idea a lot. As for the issue of timed injection, I think a lot could be accomplished with a Seebeck-effect probe, a transistor, and a solenoid-actuated valve. The temp peak of combustion would send a voltage signal to the transistor which would allow current ...

Dukast 2500B

We have had a number of threads on the old forum regarding materials even concret has been suggested. Viv Interestingly, nobody has suggested castable refractory, which is readily available for $35 a bag (55 lbs.) down in Ottawa. I'm eventually going to make a cupola furnace or an iron forge or bot...

Cool!

Thanks for the graphics, Viv. I had no idea those little drill pumps created enough pressure to mold the metal that way. What guage is that steel?
