building a gear box for counter-rotating props in 1/72 scale
Posted by Putsie on Wednesday, September 27, 2017 9:05 AM

Hi folks,

In my never ending quest to complicate my model projects (ha..ha..) I wanted to build a counter rotating gearbox for several aircraft with counter rotating props.  I work in 1/72 scale so there isn't a lot of room.  I have the schematic, understand how it works,  but does anyone know where to purchase small gears or maybe even a ready-made gearbox ?

THX

Hey Guy !

You might be able to find them in very small sizes at anywhere that sells Quad and Octo copters  and Helos. T.B.

Try Northwest shortline. They make all kinds of very tiny gears for model railroad locomotives.

You could also check out Walthers. Also a model railroad supply site.

Or..... find some cheep (broken ) watches at a flea market or garage sale, and pull some gears out of them.

                      Dont worry about the thumbprint... paint it rust and call it "Battle damage" !

There is a company called Small Parts that features hardware- mostly small fasteners, but they may have some gears.  There is the company that is an offshoot of Edmund Scientific that has some gear sets- forget the new name.  And an electronics supplier, Jameco, has a few gear sets.
