I found this company while looking for something else – Ya gotta love the Net!!
Don’t Know if you got it sorted out or not but do post what the results were for us to enjoy.:cool:

Truculent AMEJust my $.02 worth.
You might get lucky and find a cheap scanner that you can modify to work with the old glass slides but I think that is a crap-shoot.
Go to that “ebayplace” and type in Agfa Duoscan in the search bar. Find a good deal on one of the ones with the slide out scanning tray. I have the T2000 XL with all the trays and I can pretty much scan everything up to about an 8 x 12 inch negative. It might not have the greatest of resolution but there is a 4 inch full length strip that you can do in high resolution – 2000 dpi and then manipulate in a good graphics program to increase the resolution.
When new these scanners were used in pro print shops – cost about $8000.00. I got mine for $60.00 plus shipping – but – and this is the kicker here – they are scsi interface so you need to get a scsi card. I have seen USB – scsi adapters on the bay as well but don’t know if they will work with the newer systems – I am a die hard Winblows XP user and my last computer build was a problem as most scsi cards require the old slot style motherboard.
They are big and heavy and nothing comes close to what they can do for the money. I use VueScan as well – works like a dream and I do my manipulation in Ulead PhotoImpact. PhotoImpact is about halfway between the simple programs and a full version of Photoshop. It has a very good engine for increasing resolution and then you can increase the size.
If you do go this way make sure you get one with all the trays. You might get lucky and have enough room to put your glass slide in a 6 x 9 cm slide tray cutout. If not then you can use the full size glass tray.
I also have a Microtek M6E scanner with the transparency lid – I have had good results using this scanner – also a scsi interface – by wetting the glass slide and the scanner lower glass with distilled water and then placing it on the scanner glass. This helps prevent the newton rings and also will increase the contrast a bit. If you are going to try this method find the least valuable slide to test – scan the slide as best you can first dry. Some people like to use an oil but I find I have more problems with bubbles when I use oil.
If you want some more info just send me a PM – I am an old film and slide guy who builds his own cameras etc. so have some places that I can direct you to personally rather than tying up a lot of bandwidth here.

Truculent AMESome interesting info at the Pathfinder Museum site.
IIRC the Mozzie was the first of the line of aircraft that inspired the “Redux” method of construction with the Sea Hornet using that technology first.

Hope this helps a bit???
When the engine is running the oil pressure system is supplying oil flow to the rod bearings and the movement of the pistons inside the crankcase will fling oil all over – this oil is collected by the crankcase sump and a scavenge pump driven by the engine will then return the oil to the tank – same way as the valve train in rocker boxes are scavenged.
On shutdown – some engines requires a short higher rpm just before shutting off the engine to ensure those sumps are in fact scavenged as completely as possible.
After shutdown – the residual oil will drain down to the lowest points – which will include the piston skirt area. Depending on the thickness of the oil – the temperature – and the condition of the rings to cylinder sealing the oil may seep past the rings into the combustion chamber. Thus the requirement to ensure no hydraulic lock before starting the engine again. Some engines are good at sealing others are not so good – thus the joke about “If a radial engine is not dripping oil – there is none left in it!!!”
On starting the oil will be flung all around again by the motion of the piston and crank parts and once again will be scavenged back to the tank.
Is this what you are looking for??

Truculent AMEIs nice to see the aircraft back flying!!!
Here is one of my photos from the Red Bull Windsor race – I think it is a bit evocative as Race Day was the 6th of June – 66 years after D-Day!!!
I am pretty sure on that day 66 years ago there was no one who would have thought that this photo could ever be taken!!

I have seen the 100 deg and the 120 deg cutters but not a 90 deg???
Have you tried these guys??

Truculent AMEDr. Forrest M. Bird
Dr. Forrest Bird is an amazing aviation person who has done work that should qualify him for “Hero” status.
He, like so many others in aviation, are overlooked and to a certain degree under-appreciated. His contributions to the current state of medivac aircraft and equipment is probably not known to the general public – yet formed a lot of the base for what we do today.
Here is a link to his lengthy career and contribution to both the aviation field and the medical field. The Bird Innovator PBY was just one of his many modified aircraft – and he is no slouch at that task!!!

Thanks Doc!!!!

Truculent AMEIt’s actually the “Bird” Innovator!!
We had 2 aircraft that I worked on that had the airstair door – C-FCRR and C-FGLX – both were modified with the airstair by Canadian Pacific and other than a little bit of extra weight did not impair the flying characteristics in any way. Sure made it a lot easier to load up the self loading freight!!! Going up the ladder into the blister was a pain in the butt and not very modest in windy conditions for ladies wearing skirts and dresses.
The modification of adding a couple more engines was well thought out and was for take off performance – hot and high – for use in remote places. The downside was the fuel consumption in cruise suffers because you don’t need all the extra weight and drag that the extra engines produced. Plus the complexity of having 4 engines and the maintenance of those 4 engines 17 feet off the ground would not have been an easy task.
IIRC the aircraft had provisions for a “boat” to be slung under the wing and this is most likely what would have caused the loss of performance – not that a PBY has much of that anyway – you are basically pushing a semi-streamlined brick through the air and like a displacement type boat adding horsepower to acheive more speed gives you diminishing returns due to the drag curve.
Here is a picture of it without the extra engines:

I think the object under the left wing is the “boat”
The PBYs’ took me a number of places – around Canada – the States – South America, – and Europe. From a maintenance side of thing they were not an easy aircraft to “Love”.

Here are a couple of links to some previous information on the Canadian Yorks.
They were abused – ridden hard and put away cold and wet. The only ones left in Canada are the wrecks left in the great white north. There was a complete one located in The Pas Manitoba in the late 60s but it ended up outside and was set on fire by the locals!! Pretty sad end for this aircraft.

If you scroll all the way to the end of the information there is another link posted there.
The “Piston Airliners” book noted earlier has all the details and even though it is factual and dry reading has some really good information.

Hey!!! I’m allowed – its’ got Bristol Hercs!!!;)

Truculent AMENot totally forgotten!!!!!
Here is a low res shot of some artwork that I did several years ago.
CF-TAJ – Was owned by Midwest / Transair in Manitoba Canada and used this paint scheme.
Never worked on this one but did have a bit to do with one of her sisters when they were running them out of Churchill Manitoba. Best way anyone has found to change turbine fuel into noise!!!:D

Truculent AMEI don’t have access right now to the Mk111 Pilot Notes but I do know they did use them.
One of me Dads’ stories was how he was distracted one night and somehow missed setting them – full bomb load – said he knew something was amiss when the aircraft accelerated quicker than normal – the nagging feeling caused him to rapidly go through the checklist again and realized he had not set them. He said he waited until about the right distance for the takeoff point and selected them down – and just flew away. Said he never forgot after that!!!

Truculent AMEI had the pleasure of knowing one of the “Erks” that worked on the Sabre in the Typhoons. Bill was one of the best engineers I had ever come accross and his many stories kept us all well entertained.
He always said he had a sense of humor – but that the time it was tried the most was doing Sabre engine rebuilds in the field – they did it within a tent to keep out the blowing sand – so presume he was in the Middle East or a desert somewhere. He had one story where they were just about to put the engine back together after everything had been cleaned spotless when some clod opened the door of the tent and the sand whirled in and coated everything. 2 days worth of work gone in the blink of an eye!!!
Bill claimed it was the most interesting engine he ever worked on and that the craftmanship was beautiful in its own right. Claimed they had to do the assembly using white cotton gloves so that fingerprints would not be transferred to the highly polished and stressed parts.
I wonder how so many of us newer engineers would have fared under the same circumstances?? Of course those chosen had the best training in the world for their jobs!!!!
I know that many appreciate what the ground guys did – but I really wonder how many have any idea of the sacrifices that these guys made as well. Modern day maintenance engineers are considered by most to be just glorified mechanics when we are so much more than that.
Thanks for the thread – allowed some very good memories of a very good man to float up to the surface.
RIP Bill

Truculent AMEI see that it has sold – so someone probably knows what it is – or just liked the looks of it. – oops missed the rest of the ebay ad – just saw bidding was over – no bids!!
Possible that this is not even aircraft as Dowty made reduction boxes for hovercraft as well as for wind turbines.
Interesting thing to me is the lack of part number and serial number on the data plate – unless the data plate photo is so bad that it can’t be seen. Possible this was a prototype???
Always love a mystery!!!:confused:
