That was at Rand Airport, South Africa. The Spitfire flew reasonably often, and that was quite an inspiration. Sadly, the aircraft was sold and flown to a new base, and the new owner was killed when he crashed it a few weeks later. I think that was the last example flying in South Africa. We also had a Sea Fury based there for a while. That one was not as nice looking as the Spitfire. It was a monster, with a huge engine, very apt at converting a lot of fuel into a tremendous amount of noise!

I just did. Went for a walk and heard a plane approaching. Civilian planes fly over our bases here all the time, so I wasn't surprised, but did look because there was just something about the sound. It was unmistakenly a Spitfire! Flying West to East. Beautiful! There are a fair number of Spits restored and flying in Britain but it is a real treat to see one fly over just out for a spin and enjoying a great plane on a great day.

It was indeed the last flying Spitfire in South Africa, and aw a regular performer on the UK airshow circuit before that. The Sea Fury, I think, would have been the ex-Old Flying Machine Company aircraft from Duxford (its identity escapes me at present). The South Africans did have another Spitfire which was flying up until 2000 - TE213. This aircraft was very badly damaged in a forced landing, and was thought to be a write-off. I think she's being rebuilt to fly again, though. > Message Received: Oct 10 2005, 09:39 AM > From: "Serge VIDAL" > To: "KRnet" > Cc: > Subject: Réf. : KR> Spitfire > > I was lucky enough to share my hangar for a few months with a couple > olt > timer aircraft, including a pristine Spitfire.

Joachim +++++++++++++++++++++++++++++++++++++++++++++++++++++ It would have been a 500 mile round trip by auto and it takes me 5 hours each way. As the old saying goes,"you can't get there from here, you have to go around". My 2.8 hours in the KR included some "buzzing" around time in the area and doesn't take into account the ground time on each end. Any way you figure it, the KR is still the only way to go!!! The "bootleggers route" usually includes a ferry boat ride across the Illinois river but I'll trade that for the view from above the clouds any day.

having just looked at these 1835 pistons they are real top heavy
in relation to the gudgeon pin- mahle type
just wondering what the effects of this is
may not be a problem
but in a flat 4 i think it may encourage wobbling

there does not seem to be much support from the gudgeon pin downjust
some little tab about 40mm by 13mm which is the widest part i think
but wear this small area and it will wobble even more

btw is ther anyone who has hight time engines on the original pistons
rings and bores .
beginning to think looking at some of these vertical lines in the
bores that an air filter might be a good thing

view s please
phil

A short skirt is generally permissable on a forged piston because of the greater strength over a cast piston, which uses a larger skirt. Wobbling? Not if the bore is correctly set up. If it starts to 'wobble" you'll hear that distinctive hollow slap noise. As for the grooves.....yea, an air filter is good, but you must balance between your deisred airflow through that filter vs. it's filtering capabilities. A 10 micron paper filter is going to be very restrictive as opposed to a cotton gauze/mesh filter like the K&N. Keep in mind that some of those verticle grooves may have been caused by carbon particles comming loose from the combustion chamber, also. It is one of many things you will see if you have run it with a rich mixture for extended periods.

We cured this by cutting .020 off the edge of the piston from the top down to the top ring land to give the lead sufficient room to build and slough off. David Roe ran his 1/2 VW for 700 hours with no further scratching after modifying the pistons. The pistons and cylinders looked great when the case failed after 700 hours. We also did the same mod on the 2180 VW I built for my Avid Flyer. It also showed no scratching in the bores when I sold it.
