Fairey Aviation Propeller drawings

Hi all,

I’ve been having a rummage around the filing cabinet tonight as I knew there were some Fairey Aviation drawings/blueprints in there.

I’ve come across the following types:

A66753 for Gipsy Major 1, 8 & 10mk2 (pics attached showing drawing extracts) for Chipmunk and Auster

A66875 for Gipsy Major 1C, 10mk1-1, 10mk1-3, and 10mk1-7
for Miles Gemini
(the pic showing special finish for racing isn’t particularly clear but states: Propellers manufactured for racing purposes on the WPO Nos quoted below must have the rear face of the blades painted with matt black paint to DTD34 and subsequently rubbed down with fine rubbing paper to produce a smooth surface before application of the yellow tips.

This is for WPO C4345 and C4904

A66167 for Walter Mikron II for Tipsy B and Fairey Junior

A67931 for Gipsy Major 10mk2 for SAAB Safir

All the above drawings only give details for the blades to be anodised and dyed black and then yellow paint applied to the tips, with the exception of the racing propellers mentioned above. The only part to be painted black are the bosses, with the exception of the faces which contact the blade or the hub flanges.

On the drawings there is an area depicted on the blade which is not far out from the painted markings shown in the other pictures, this is detailed as being for the surface table and c/l of the surface table where the tracking dimensions are taken from. So although the painted line may not be on the blade from manufacture, perhaps as part of the checking of the blade tracking there is a painted datum and that’s what the line is????

Some of the blueprints are stamped up WESTLAND Engineering Division 24 Sep 1984, when my father obtained these from Westland he was told that these would be the only copies as they were going to destroy the others they held, how true that would be I don;t know.

If you need anymore detailed views of the drawings let me know and I’ll see what I can do as they are too big to scan areas, but may be able to manage more pictures.

Hope that’s of some use!

Regards

Dave
