Except one vital difference. The Finnish Ripon was a special model to be made in Finland and is different to the British Ripons in that the rear fuselage was plywood and not fabric. Essential dimensions can be obtained from it but we don't know just how much the difference is. Only time will tell, but i think a trip to Finland is essential.

There is a way of measuring using photographs. What is needed in each photo is something that is of a known dimension such as a ruler scale and the focal length of the lens. In geography we call it photo rectification but it is accurate if done right. If you run it through a program like AutoCad you would then get correctly scaled and dimensioned drawings for each part, section etc. Beauty about it is that you would only need to visit the aircraft once. Today you can print 3D copies of parts so basically if needed could make blanks of parts prior to manufacture or rebuild. I am not an engineer but I think on criticial parts where they have to be manufactured from scratch that 3D printing may be an option, albeit expensive, before committing to manufacture.

So you're suggesting a Blackburn Baffin Supporters Group?
The "Baffin Boffins"
As a long dedicated fan of the Baffin I think this is a great idea to both support the project with raising funds or finding parts, and also get the story of the Baffin's rather important service career out there
LOL, I had thought of Baffin Boffins but reckoned it implied we were all smart arses... :-D
aircraftclocks. Very interested to hear you have the manual Vol. 1 you mentioned. Does it have an AP number. As we have no manuals and very little technical data, anything is extremely valuable for this restoration.
But where will you get details of the focal point of a lens from a photo taken 70+ years ago?
I'm not meaning old photos. I was talking about photographing the Ripon in Finland. From what I understand it is an extant example so if one is able to photograph parts etc., that no drawings exist for, then one can obtain detailed data from the image.
Further pictures of this Baffin project. The first two show the front frame extended by one bay and the addition of the main fuel tank. And before anyone points it out, yes, the tank is in the wrong way round as the filler should be on the other side.
The next shows the main wheels plus a very good rim. Also a spare wheel.
And last, a shot of the propeller hanging on the wall, and the propeller boss.
Hi Richard. The structure of the Baffin is quite different to the Hind. Whereas the Hind has all metal tubing for the airframe, the Baffin has composite wood/metal construction. At the last joint shown in the latest photos the wooden longerons attach and continue for the rest of the airframe. This aircraft occupies a special place in the hierarchy as it is the link between the old wooden frame aeroplanes and the newer all metal ones. The wings also have spruce spars but the cross tubes are metal, again showing the transition. I will scan some diagrams and post them showing the airframe soon.
