I've completed the parts for a differential for a 1/12 scale gearbox I'm making.

Here it is assembled next to a penny.

The central pin will be cut down so it's flush with the cage and slotted for a screwdriver. This is the first time I have been able to test the bevel gears I made for this and I'm very happy. Everything meshes smoothly.

Excellent - that’s a very fine collection of parts. Looks like you accidentally posted the same pic twice - the assembly doesn’t show.

Wow, very well done! What module or dp are those gears?

Very neat, very tidy, very impressive! If that's going into a gearbox, what's the gearbox going into?

Steve Crow · « **Reply #9 on:** April 26, 2021, 04:16:04 PM »

The gears are Mod 0.3 and the gearbox is a Hewland FG400 to mate with a Ford Cosworth DFV V8.

Very nice :-)

That's the kind of thing I've been wanting to make for years. Maybe I'll have the skills one day.

Nice job!

Funnily enough, gear cutting with the right cutters and a dividing head is not difficult. It gets interesting when you don't have the right kit and you have to grind up a single point cutter which matches the mating gear...

A worthy and ambitious project! I'll be looking forward to seeing more of your progress.

Very nice, I’m contemplating a future project where I may need to make one myself. Mow I can refer to yours!

Mod 0.3, that is pretty small; much smaller than the 0.5M gears I can cut, congratulations !

Nice, but where did you get the giant penny? I've seen U.S. pennies that size from time to time but never one with the queen on it.

Seriously, that is a really nice set of gears.
