Thanks for sorting the photo Dave. Maybe the property owner in Blenheim where the Vampire was collected from may know. It may even be the same property.

Some time ago Phil Rowse donated a large metal model of a Mosquito to the museum if we would complete it for him. The main items required to complete it were the canopy and the props and spinners. Chris is working away on the props and spinners in amongst other jobs and Lance and I have made a plug and the supporting base to enable us to vacuum mould the Perspex. We have been preparing the oven and getting it working and I had the plug and mould platform ready to go. We have convinced ourselves that Friday will be the day to have a go. Will let you know in due course what transpires. Mossy canopy mould 160518 by Mike Feisst, on Flickr

One of the people from Gisborne arrived up today and we pushed 2505 out and started the engine so that he could see the operation. The engine was shut down and then he swapped places with Bruce and started the engine himself. A successful morning. IMG_2238 by Mike Feisst, on Flickr IMG_2241 by Mike Feisst, on Flickr

We also had an attempt at moulding the canopy for the Mosquito model but we weren't successful. We were trying to use 2 .. Perspex but it was far too thick and too brittle. We got a nice shape over the top of the plug but couldn't get it to sit down against the sides so we are back to square one. Does anyone know of a source of thick clear PVC sheet that we could try on this plug. We are thinking about 1 mm or slightly less. The plug is 450 mm x 200 mm x 90mm so is a fair size.

You could try acetate sheet, hobby and craft stores sell it. Perhaps try Spotlight.

You could also try 'Composites International' in Papakura near near Ardmore Airport, either for sheet stock, advice or even to 'blow' it..? They blew the new tear-drop canopy for the Spitfire at Whenuapai and have made all the transparencies for the Avspecs Mosquito production line. See: www.compositesinternational.co.nz/ New Spitfire tear-drop canopy. Mosquito Canopy.

See: www.compositesinternational.co.nz/ New Spitfire tear-drop canopy. Mosquito Canopy. Beautiful mouldings as you would expect from professionals. I used to work with the two people who started this company, back at NZ Aerospace many moons ago. I can remember blowing canopies for the Fletcher.

With some help from Rob Treanor and Phil Wilkinson from Cambrian Plastics we have purchased some PetG plastic sheet in .75 mm and have been told we should have much more success with this. A few tips about heating and the vacuum pad should also help so will see what happens on Friday.

I can recall on my Airframe Mechanics course at 4 TTS in 1968 being taught how to calculate the temperature and time required to mould perspex of different thicknesses, Unfortunately in the last 50 years my course notes have gone missing. Geoff Cooper may remember

Geoff Cooper may remember Thanks Shorty. Rob and Phil have been very helpful with hints to get the temperature and timing right so hopefully we will have more luck next time. I thought that 2 mm Perspex was going to be far too thick for us but that was the thinnest sheet available. And I couldn't locate any reasonably thick acetate sheet but we seem to have that under control now. The PetG material is known for its ability to handle deep draws which is what we need.

Ah this is Roger van der Zanden who runs the museum in Gisborne and owns two Austers. Roger is a lovely chap and is currently getting a rating on the Harvard.

We have started getting the jet engines out of the transport crates and put them into the containers. This needs to happen as the crates are well past their use by date and will get the engines in under cover again. 300518 (5) by Mike Feisst, on Flickr 300518 (2) by Mike Feisst, on Flickr

Jack and Nigel Godfrey came over today from Hamilton and Jack has donated a couple of his beautifully crafted models to Classic Flyers. Jack has been modelling all of his life and has won numerous awards for them. He also built the full size Bristol Scout that now resides in the museum. Nigel is our go to man for metal cutting and fabrication and we would really struggle without his generous help. That is the Scout behind him in the first photo.
