| The start of
the combustion chamber.
|
|
I found the easiest
way of removing the plastic seal inside the tube was
by applying a heat source to the outside and then scraping
the plastic away with a flat ended screwdriver.
|
|
|
|
This will form the DIYGT's Transport
Fame.
|
|
Transport frame fabricated, with
the Turbo support bracket mounted in to place. The mounting
plate is spaced 2mm above the frame to help reduce heat
transfer from the turbo to the frame.
|
|
|
|
Combustor flange and neck now securely
welded on to the combustor. The circular flange has now
been cut down a little more and the end flange tack welded
in
to place. I have also marked out where the air feed will
enter the tube.
|
|
A quick test to check it all fits
ok, so far so good. |
|
|
|
I have to say, I was very happy
with the tolerance and accurate curve that I managed
to get on the pipe that will
be attached to the combustor, So It's a shame that I
cut it 90 degree's from what it should have been. Short
attention span, that's my problem!
|
|
Pipe shortened and hole cut in the
combustor ready for welding. |
|
|
|
The bent part of the
pipe has now been reattached to the inlet pipe at the
correct
angle and then welded to the combustor.
|
|
Again, a quick fit just to check that all slots in to
place. |
|
|
|
The Oil filter housing has now
been bolted on to the back plate, which in turn has been
tapped
with 1/4" BSP threads so that two 8mm pipe fittings
can be securely attached in to place.
|
|
The oil filter has now been mounted
on to the frame and the required sensors bolted in to
place, a quick pressure test reveals no leaks from the
homemade back plate assembly, which is nice. |
|
|
|
At the top of the picture you can
see that a fuel drain has been fitted in to the
flange of the combustion
chamber
so
that any excess fuel can be drained safely away. I
have also fitted a NC valve directly on to the injector,
this
will make sure that the engine will stop at exactly
the moment the stop button is pushed.
|
|
1/2" high temp hose is used for
the oil return path.
|
|
|
|
3/8 copper pipe and compression
fittings are utilised for the oil feed.
|
|
Oil pump mounted and partially plumbed
in. |
|
|
|
Fuel filter attached and I have
also marked the location of the igniter position on
the combustor. |
|
An air tap-off has been fitted in
to the side of the combustion chamber so that combustor
gas pressure can be measured via a gauge that will be
mounted in to the control panel.
