In the 4th pic it appears as though your flameholders ( 3 lengths of angle ) are pointed in the wrong direction , the sharp edge should be pointed towards the turbine wheel so that theres a gutter on the downstream side for the flame to hold in .
Cheers

Cheers John Are they really? From the looks of it he has done it right, the exhaust travels from the table upwards and the V-irons have their edge towards the table. |

Hi Anders
LOL.......everytime I look at it I get a different perspective ,............ now that you mention it ,the "outer" end looks OK but at the "apex" it looks the other way ............ its confusing :-(
Cheers
John

Square tubing is a pleasure to work with compared to round tubes, the damn notching can drive a man insane for sure. |

Looks lovely, sleek flow of the engine layout :-) one thing i might add though is that there is going to be a lot of changes in the geometry of the burner can and intake / discharge pipes throughout the envelope of operation... unless you've already done so, a cut in the compressor discharge pipe would be useful (where it's welded), maybe make a 5-10mm gap and fit a tough section of silicon hose.

I've thought about it to so I'll see if I can find a hose that fits on the compressor pipe.

Where is the suspension? I see only rigid steel tubes. |

Last Friday I installed the engine in the chassis. The black clamp band in the picture is just to keep the engine in place when I welded the brackets.   Today I welded the roll cage to the chassis.  And tomorrow I'll put the fuel and oil tank in to the frame.  |

Hi Timmy, you are really coming along well with this,I assume that there is more to go into your roll cage? If not there are just a couple of things you may want to look at. The 2 rear hoops weld to the cross bar, you may want to look at having 2 more extending down to the floor following the rear of the seat in case it lands on the rear or the top. Also a couple of straps around the side inline with your helmet to stop the drivers head coming out the side in a bad roll. Just for interest, this is a roll cage from the DLRA rule book.  Cheers Ian... |
