no real news to update with - got a million and one things going off (including starting a Land Rover tuning parts company!) so this has slipped down the list of priorities
Tweaked the holes so the buttons fit properly, and so the brass side plates fit properly - then slapped it together with all the m8 nuts I could find![:P](//storage.proboards.com/forum/images/smiley/tongue.png)

All looking lovely
Looking like it's going to cost approx £15 for a deep 50mm hole saw + arbor. Bit annoying, considering it'll only be used once. Needs must and whatnot
However, this new dry-run has shown me one thing - the current flame tube needs tweaking
![](http://i8.photobucket.com/albums/a46/Chairchild/Jet%20engine/IMAG1098.jpg)
The flat disc needs to be at least 1/3 in from the edge of the intake charge pipe, as it stands all the airflow is kept away from the far end of the flame tube (not what I wanted!). This is more how it should look:

Easily tweakable, but I'm having second thoughts on the whole setup as it stands. Besides that singular one I used as a reference at the very start, I've not seen a single other example of people successfully using exhaust tube. Not liking to fail on the first go, it'll change to a more classic flame tube style - including increasing the tube diameter to 2x the inducer diameter, rather than my current choice of 1x inducer diameter....

This was chosen as it made fitting to the turbine easier - but that should always have been a secondary consideration, getting it self-sustaining should've been my priority.
I've also picked up another vital part of the puzzle - the airflow to get it started:

A massive 500w airpump, which I rebuilt a couple of years ago to help with my final year project at uni. Ended up buying it off my tutor, as it was just lying around getting in his way.
So, should have a new flame tube, and fuel system designed in the next few days![:)](//storage.proboards.com/forum/images/smiley/smiley.png)
