Anyone interested in building a “proper” Climax? There’s a guy on eBay selling some old Tradeship hypoid bevel gear sets designed for slot cars.

Climax, or Shay?

Climax. Shay’s do not need offset drive shafts - this “hypoid” gear has the drive shaft below the axle, so the drive can continue to the next axle where there would be another hypoid set.

Offset drive gears are tricky to make, and currently no-one makes them. These are probably 30-50 yrs old. They were produced to lower the CoG of a slot race car. Lots of threads:

His trucks came from David Bailey of DJB Engineering and are no longer available, as David retired.

Super looking engine, looks like something one of our MIK builders could have done

Pete, I looked and looked at your picture, and the skew of the teeth looks very minimal, compare it to you second picture.

The offset does not look very great, just maybe a tenth of an inch at best.

1/8th inch. Just has to clear the axle.

[BTW - there’s a couple of sellers on eBay. That photo came from the guy who wants $14.95 a pack.]
