Very interesting information. A friend of mine recently painted his WW1 replica with water based house paint.

It was covered with ceconite, then Randoproof (nitrate dope) and from then on with house paint. Looked great, unfortunately he pranged it. He is now building another replica and intends to do the same. Cost is the driving factor (about $100 vs $4000).

I would like to do it, but am not game. In a way could get back to what I alluded to earlier, if the costs were less then you might recover the aircraft more often and in doing so, give the underlying structure a look over and patchup!

Ceiba Geigy K134 is an epoxy that needs to be above 20 deg C to cure and really above 40 deg C curing for max strength. Not a problem in my workshop in summer 35-37 degrees is common, however for 2/3 of a year the tempature is too low in the workshop and the parts being glued need heating. Heating them is a pain!

What are the normal range of glueing temps?

cheers

Indeed – which perhaps has the unwitting resulult of raising the standard of authenticity – no more ceconite covered Hurricanes these days!

A grade cotton or Irish linen – no thanks Ceconite YES please. If it is going to fly then use the best. Ceconite doesn’t rot which cotton does, not sure about linen.

Because cotton rots, the aircraft needs to be recovered every 7 years or so, which gives the undering structure a chance to be exposed and checked and repaired if necessary.

However if modern high quality glues are used then the structure does not “let Go”

Where is the debate about using epoxy glues (is it next?).

I really don’t care.

Forty THOUSAND drones & robots? I’d like to see the source for that number. They make the drones just down the road from here & the number is barely in the hundreds… :rolleyes:

The source is the ABC (The Australian National Radio/TV/Internet Broadcaster).

The drones included vehicles that detect roadside bombs and defuse them, ones that detect land mines etc – the list grows every month. It is a paradym shift much the same as aircraft were to the navel battleships, machine guns were to calvery charges.

ZRX61 I guess you will need to get yourself a bit more up-to-date. Even my local airfield has a number of UAV’s operating from it (Boeing ScanEagles).

A Friend of mine (a former RAAF Photographer) bought to my attention that where aircraft have pranged on the mountains in the middle of New Guinea, there is very little corrosion of the alloy because the rain water is very pure. He told me about a wreck that they visited that was high up in the mountains where it crashed in the side of a cliff.

He said the paint work was quite intact and the metal free from corrosion.

Can this be correct? I have often wondered.

What an interesting subject, I hope there are a lot of posts

Interesting consider WW2 and the industrial situation/financial situation that existed then and now.

I would like to know did the companies like RR make a lot money out of the war like the Americian military complex makes out of the current wars.

Another thing that comes to mind is that with the drones in Pakastan War, normally a airman goes to war with a high risk that they mightn’t return.

In the Pakastan War, the CIA civilians are running the war (office hours) and their is no risk to them personally. Bit like the civilians working in the manufacturing entities referred to elsewhere in the thread.
