I have been looking though old photos to try and decide if the nuts were individually split pinned or daisy-chained with locking wire. You cannot trust the details of old engines which have been tarted up for display in museums. There are no flying Jupiter engines out there anymore.
Do you not have a copy of the Jupiter's Care and Maintenance Manual? That should tell you Jo
Jo, In that case, you would be horrified to learn that the RAF approved method for split pins is to cut them short and bend only one leg through 30 degrees, leave the other leg straight. The split pins with a single bend will never fall out and are easier to remove than split pins tied in knots. You never try to reuse a split pin.You both ready for the Guildford Open Day?
They normally sign every tool and part out then every tool and part removed back in but the tales of what is found on an aircraft during maintenance I was thinking also of the pilot being able to walk round and just having to check one wire was securely in place rather than every split pin prior to every take off. You know what fly boys are like if you make them do more than they have to prior to go playing .Jo
The nuts in that drawing look a lot nicer than the 2BA that are available that just have square cornered milled slots in a pressed nut. A quick bit of CNC with a ball ended mill will get the round section and the round bottom slots done quite quickly.Jasonb
Not the most exiting day's work, but another job can be ticked of the list
