Oh my, this could lead to trouble. First things first, hone some skills and get the current smaller one running sweet, then we can talk turkey about that.  Cheers, Marc. |

Had a busy afternoon, got the new flanges cut, made up the flame ring, shouldn't have any issues with air leaving the CC without a visit to the flame tube now       I didn't realize, wasn't paying 100% attention, went a tad overboard with the flange, 12 studs instead of 8, but i guess if anything is worth doing, it's worth over doing. Also, i mocked up the air inlet position so i could take the measurements for where to cut the hole in the CC, as i calculated, will fit in between the primary and secondary holes in the flame tube, so it hopefully can spread the air without blowing directly thru the holes.   Any thing i need to have a second thought about?? Cheers, Marc. |

Hi Marc
Is there any chance you could position the delivery diffuser a bit "lower" between Secondary and Tertiary holes ??
Having it in the position between Primary and Secondary is still going to produce some variations in flow speeds/pressures at the Primary holes .
Cheers
John

Hey John,
Yes i can as a matter of fact, i have the same spacing between the secondary and tertiary as i do with the primary and secondary, only trade off being will make the pipework "interesting" and would have to trim down the funnel. But nothing i can't handle.
Cheers,
Marc.

Got a little bit done today, flame ring is completely welded now, and the flange it is attached to, along with the flange that has the reducer and the air inlet are all tacked in place.  |

Got it all welded up today, only things left to do are to weld on the turbo flange, make the mount to the frame and make the air inlet pipework which will be done once it's all mounted on the frame to make life easier. Gave the new combustion chamber a test run with the leaf blower on the bench. www.youtube.com/watch?v=NkH8vWPJDhwCertainly makes for a highly efficient heater for the garage |

Nice, that flame is really uniform and consistent! what was the fuel pressure during that run?

Hi Marc
Nice combustion :-)
Are you measuring the outlet temperature from the combustor during the test ?
If you are, and the max temp is at say 850 deg C (same as when mounted to turbo) then your test will be producing a good representation of what will happen in "real life" once you fire up the engine.
Cheers
John

Hey racket, yeah I got it up to about 550-600c this morning when I was using it to heat up the garage. :lol: As for pressure, not sure, the gauge is broken, do it by feel  |

Hi Marc
Yep , a good space heater , lotsa CFM of hot air :-)
Cheers
John

Hi Marc Yep , a good space heater , lotsa CFM of hot air :-) Cheers John Not wrong, certainly needed first thing this morning. I got the T3 flange tacked in place this morning so i can get a proper idea of the air inlet pipework. Not the best to work with, i cut some pieces to see how i'd go doing a lobster back for the tight radius.     I was trying to have them come outwards and levelled up then just curve them into each other, but, i'm not happy with it, especially after i rotated the compressor housing, AFTER, doing this stuff and realizing, there is a better way to do this. Better start cutting more pieces..... Cheers, Marc. |

That's a tidy looking unit, I love the conrod mounts for the oil tank.

That's looking much more betterer Marc.....once you get all the welding done it should be "all systems go". Nice looking setup indeed. I'd like to come and have a look at it in person one day.
Love the CC video too...looks to be working very well, nice consistent flame....once you get the engine sorted on propane you can go ahead and run some "real" fuel through it..!
Cheers,
Smithy.
