Starting Your Pulsejet

What sort of fuel are you going to use? If you use propane, I don't see why you couldn't just use a match or cigarette lighter held at the exhaust to ignite it. Some pulsejet experimenters have successfully used a bbq sparker or a welding sparker too, even with liquid fuels.

Spin It On A Lathe

Lately I've noticed that the messages of some participants have been peppered with references to controlled substances. This has given me an idea, and perhaps somebody out there with the required machining skills could give this a shot. It seems to me it would be relatively easy to spin a Dynajet-si...

Re: free plans on Ebay

Didn't Delorean use stainless steel and cocaine to go back in time? Or did he just make time stand still. That's fun too. Mark Here's another great buy on ebay. Buy it now, you who love hydrogen, you know who you are. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2568084521&category=4661 Talk ...

Round Stuff

Full round or pipe would probably work just fine, but drilling it and riveting it in place would probably have been an aggravating experience, so I decided just to go without for the first run. My main goal right now is to actually achieve pulsation, then acheiving lengthy pulsation can come later.

Test Day Bummer

Thank you for your encouraging comment, Stephen. I tested this new valve system and it didn't work. Leaving the paper on the reeds was a big mistake. Also, I found two pinholes in the weld joining the cone to the combustion chamber, so I think that might be part of my pulsation problem. I still have...

Losenge-Valve Array Completed

I put it all together this afternoon. Sorry guys, no devices to limit valve travel. I couldn't find any half-round rod and I'm getting really impatient to try this out. I can always add it later, I have plenty of valve material. I left the sticky white pattern-paper on the front side of the valves j...

My Basement, circa 1996

I just can't shake that silly name, can I? Oh well. Yes, the idea sounds quite appealing Bruno, but I would maximize the footprint of my light by growing a tableful of smaller pulsejet plants, their roots soaking in a dilute, pH balanced, aqueous solution of phosphoric acid and ammonium nitrate. Aft...

Full-Scale Tesla Turbine Disc Layout

Working off one of Tesla's patent drawings, I calculated some proportions and simplified construction enough that I can actually build this thing. For a technological genius, he wasn't much one for geometry. It would take me weeks to make it his way with all those star-shaped washers and that keyed ...

If You've Got The Time, I've Got The Cones

The actual step-by-step mathematical operation is described here:

You don't even need electricity, let alone any kind of numerical processor, to make a cone this way. Any cone, any size, anywhere, anytime.

Re: Mosquito Coast

I checked Frank's site a long time ago. I can't remember anything about it though. My design will be a lot simpler than most, as I only have relatively primitive tools at my disposal (drill press, Dremel, bench grinder, acetylene torches, circular saw). I'm just going to try a small single-stage des...

Applets Replace Apples

Actually that old Apple was my very first gateway to the internet, back in 1994. I hunted all over town looking for a modem and finally found a real hotrod - 9600 baud!!! So I hooked it up and logged on to the National Capital Freenet and checked the weekly police statistics for my neighbourhood, th...

Apples are for crushing into sauce!

I'm behind Bruno on this one. I had an Apple IIc back in the 80s, and it was nothing compared to the Athlon I'm running right now. I must say, however, that the operating system on that old machine never crashed once. I paid $319.22 for a Windows Me CD back in March 2000, and it is the first, last a...

Oh Good, Someplace to Put My Porn

Just kidding. On the upside, this is the perfect place to tell you all about my wood-fired, steam-driven Tesla turbine that I am almost finished designing. I got my one-inch aluminum hex rod, CroMo pipes, teflon sheet, and 16 ga. steel so now all I have to do is draw all the patterns, cut them out a...

Yes

Thank God you happened along, Mark. I had a feeling my post was full of inaccuracies, but I knew I was pretty close so I put it up anyway. Is the cobalt naphthenate perhaps dissolved in styrene? I remember the purple stuff I used smelled rather like styrene.
