is there some gear combo that I can use to run something at a similar

[Legofan4ever88]

I'm trying to make one of these:

but I can't find a seller w/ the 40 tooth gears, lift arm, and tile piece I need. Help?

EDIT: If I use one 40 tooth gear, is there something else I can use w/ the 6 tooth gear? I can find ONE online, but not 2

You don't need the 40 tooth gears. Just use a bit of imagination.

You only need one gear, use the same gear as both the driven gear and the crank.

Is it possible to lock the topic? I found a 40 tooth gear in my room w/ a small crane model i got a while back and I just ordered one of bricklink.
