Lincoln Slide-rule

[Ian Warren]

Marty stopped in this morning .. tomatoes and all Thanks Matey , I thought be ideal for some of you here
to see a Lincoln CG ,I be twiddling with it all morning .. not a Rubics cube but to give a good idea for what was
used on weapon stations and nav tables preflight correcting load helping pilots out , Marty mentioned no
instructions but they are ... well and photoed on the back there they were , great for a little twiddle and
understand the work they did , very intriguing ... simply something I really wanted to have a look at.

Well done .... if its of no use to you , pass it onto the museum , but i do recall seeing (and counting) heaps of them out there.
I have to go out there soon and sign some things .... so I'll ask if you want .... otherwise , consider it a gift from the old man.

Actually I'd would like to keep my hands on to it for the time begin , .. I posted this at SOH , I think they were very pleased you gave me the opportunity to photo the CG rule for all to see, Just so chuffed I saw the potential in giving a little actual history in photo form, many appreciated you giving me a look , least you no its safe here.

Huh.. .very cool. Never seen such a thing. Thanks for sharing.
Have you sussed out how to use it then?

Think it was Great Marty past it on to me to have a look at, I was good with slide rules forty years back, there is further detail information once slid across , you want to take specific numbers (pretend) then adjust to suit the datum , finding first I need to get weights off specifics , a weight off a 20mm shell or get to learn how they took that on as an average , also gos with the loaded ordnance , so then you want to find out the specifics on those , for example a standard RAF WWII 500LB bomb only weighted the explosive, not the casing , and then depends if it is a GP/AP or another variant , ... the fuel is easy .. that won't change until it gets used ... quite an interesting toy.

Errrr.... Ummm.. sounds like a piece of cake then

Guess it would be very hard to apply it to Flight Simulation .. be great to get some off the equipment from a Stratocruiser , then see how it or if it can work .. be interesting to get a B-377 CG rule and use it to the A2A model .

Prehistoric flight management system

It is , but used in conjunction with your hand held navigation and compass , very handy and still used today for basic flight training I believe .. or I would hope so .

Don't forget the dog

That's an ole Aeronautical Society Classic Boeing Joke of 1983/4 .... back then we had a couple of sheep in the typical Ferris wheel setup .... then had the dogs barking to get those silly sheep a running to generate power .... worked damn fine till they got all woolly on it ....
