Drill gearboxes?

[ThaddeusMaximus]

Tore down a Ryobi and another drill, both of which I found at a thrift store, and they use the same 1:36 planetary and clutch combo. I'll keep you in the loop; I think I can make a smaller, lighter, cheaper, less tricky gearbox than the VPs out of these.

Also got a Harbor Freight 4.8v electric screwdriver. Tearing apart soon. Pics to come.

If you're looking for a resource on how to implement them as well, there's a good WP here on how to use Dewalt gearboxes
