Is anyone else starting to see out-of-round wobbly Koford inline gears? We had a couple at the Fall Brawl and I put a dial on the new ones I have to see what the deal was. They have more than normal run-out.

 

Just wondering if anyone else has seen this?

What is "normal" run-out?

Yep, saw a few in person at the HVR Retro East race. It's enough to the point where you can spin the axle and see how far out it is.

From my last email with Stu:

OK.

We will see if we can think of any way to improve on that in the next batch we make.

Mike,

It's almost like the damage is being done however they turn them for chassis clearance. I assume a lathe? Reason I say that is because the aluminum hub is true.

I doubt that's possible.

 

He's looking into it.

 

Molding a true gear is trickier than one might think.

That was very nice of Stu not to take it so personal when someone voices a concern about a product!

All the Koford gears I use have been ultra true!!  I"m sure he'll figure out what's wrong and correct it!
