  ........ because you are behind your self imposed schedule and stuff to be done is stacking up, take a break, step back, slip another little fun project into the mix. It won't help but it's a bit like scratching an itch, you've just got to do it.

    all from 2 mil stainless, a bugger to form but quite pleasant to weld

   Hope to fire it up over the holiday, they're meant to have the ability to waken the dead at high throttle settings, we'll see. An alternative scenario is that nothing happens, further research suggests that they are really quite sensitive to changes in the volume of the tube sections and I have just worked from a photograph and then used what I had laying around, still, the potential injury forcast is possible to real with severe threatened later, should be fun, I'll let you know

   The igniter box took a bit of thinking about, involving several relays operating each other, I thought that ALL relays followed a common numbering system, not so, I got it in the end although the plug gap is now opened up so far that it seems to prefer arcing to the side, I suspect that it will still do the job, more as it happens

neighbors are gonna love you the noise they make are unbelievable ;D ;D ;D

Am I the only one here who hasn't got a clue what you're making there big bro?

no Andy. theres me i ant got clue wot it is either.gaz

i wont spoil it but the germans used them in ww2 ;) ;D

He's building a Panzer tank?
...actually, that wouldn't really suprise me.

nope its louder than one o them ;D

Pulse jet  ?  .............   

  ..  Hagar  .. 

Could that possibly be used to melt your way through the snow?? ;D

Melt...! vaporise more like. ;D

 :o ??? 8) ;) ;D

i thought it was a doodle-bug

Nope I'm beat also  ???

I think that may need a firearm certificate. ;D

No, it's armless that is ;) ;D

it must bee a hair dryer then.

One of those exhaust flame throwers?  :o

Brock are you going to tell 'em what it is?
Have you got it working yet?

Tell me, tell me, tell me, tell me, tell me, tell me, tell me, tell me, tell me!!!!!!!!!!

It's Brocks baby I'm keeping quiet.

   I had an unexpected break in the form of a few days away in Old London Towne courtesy of Mrs B so nothing has been done to anything for a week, however, the house is full of outlaws tomorrow and being an unsociable git I'll melt away like a wraith, and indeed wraith to the thed and give it a try, maybe photos tomorrow, or hospital !

I'll watch for the glow in the sky over Marlborough then.
Happy New Year big bro.  ;)

  Got bored taking the race car apart to alter the transmission ( again) tonight so had a little play with it. As most have guessed, it is actually a high speed hair dryer, not having a handy volunteer we just set it up on the ground to test it.

   Ignition on, air on, gas on, big bang and flash of flame, then nothing. Back the gas pressure off a bit and try again, ooooh, it runs, after a fashion.

   It will run with the ignition turned off, which is good, but not without the forced air feed which isn't. More research needed, from the extent of the heat pattern on the body it looks like I may have made the combustion chamber too long, it was all a bit of a guess at the sizes and some development was bound to be needed, but it's a start. A few shots with the flash turned off, the camera is very susceptible to shake in low light as you may be able to discern ( ! ) but they do show the heat patterns on the body

That's one serious hair dryer!
So it's a jet engine then. A "pulse jet" -what exactly does that mean? And what does one do with one's jet, now you've made it? How much thrust would that generate, (I'm sure you've already worked it out :) ). Enough to power ...? a bike? A go cart? A double decker bus? How would you mount it in a vehicle without melting everything around it? Can you regulate the power, or is it literally point & fire? Have you managed to burn down the workshop with it yet?
I'm so glad insanity doesn't run in our family, big brother!   :P

   "I'm so glad insanity doesn't run in our family, big brother!"

There's still time Andy, Brocks didn't kick in until he reached 49 ;D

"I'm so glad insanity doesn't run in our family, big brother!" ...................Sorry but I think it does Andy!

(Pop, two trikes and a Charger, and to top it off you work for the post office)

Who's Insane? ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D

Yeah, fair comment.  :P

Is it a leaf blower? i thought it was a trike exhaust system naaaaaaaa giz a clue? the germans used them in the war? is it to do with gas?

It's a jet engine! Pay attention at the back!
Obviously we all knock up such playthings when we're having a slack day -don't we?

Yep!

thought it mite be somthin like this http://www.youtube.com/watch?v=ykF3TUTI2hU

    :D, no it's one of these :-

    very susceptible to gas pressure changes, I have some ideas about that and will try to find the time in the week to have a play.
    On the subject of the big potato guns, Osma/Wavin plastic soil pipe is too brittle to withstand large charges, you need the expensive stuff if you don't want to be peppered with lots of nasty little stinging bits of plastic  ::)

All that time and effort and you could have gone to B & Q and got a weed burner ;D
Come on Brock, get some work done (Thats if you can get to the shed)

   modified the gas inlet today, junked my lovely stainless steel fabricated injector and ran the open feed pipe straight into the inlet tube, may try to run it again tomorrow, depends if I can thaw the tool box locker on the truck to get at the stuff I need. It may not currently run very well but it is a pretty colour

Use the jet to thaw out the van?

   Run the jet to thaw the locker I need to get into to get the stuff I need to run the jet ? I'll have to think about that ! Still fairly chilly out

Ah, I see the problem.  :P
What's the car in the snow?

   cunningly disguised trike ?

NO! Nothing to do with me  :o

Check out this site


http://freespace.virgin.net/dyno.power/gasturbine/gasturbine.htm

   Brilliant site, clever man. Possibly the first site I ever saved after I found what a "favorites list" was. I hadn't looked at his jets but do keep going back to look at his Nitros systems, hmmm, if only I had a spare motor, hang on, I bought one yesterday ! !, Oh dear ......

 "only I had a spare motor, hang on, I bought one yesterday ! !"

 Have you forgotton to tell me something? ???

OOPS in the s**te now Brock ;D

    ;)   all is well.

 had another go with the jet, still won't self sustain without air feed, I might try cutting the inlet off and make an adjustable sliding sleeve to go over the stub and see if the length affects it

 ;D kool Brock.

We know we wont be bombed from Marlbough in the near future them brock  ::)

   not unless I invest in a really, really long air line
