DD4H New 93X Axles diameter typo?

[LightninBoy]

Please tell me this is a typo ...

The 93X Axle measures at .093 where the wheel rides on the axle to reduce the slop of the wheel and ensure a more stable Pinewood Derby car but reduces down to .090 where it enters the body.

Shouldn't that be .091 to be consistent with the 92 axles?

No, all future axles that are made will be going to .090. I am sick of reaming axle holes.

Does that mean the 92s will also reduce down to .090 after the current stock is sold out?

 

[DerbyDad4Hire]

Yes. Every axle I carry eventually will.

I like that it makes it easier to run any axle you want. Will be really good for test cars.

 

[DerbyDad4Hire]

They should fit perfect.

Yes. Every axle I carry eventually will.

Ok, that's good to hear.

Everyone's different. What works for you may not work for others. This gives you additional options that you may benefit from.

Yeahhhhhhh !!!!!!!!!!!!!!!!!

I always thought it was crazy that a machined part didn't just "fit" when we drilled with a pre-determined drill size. Especially when working with poplar, it just seems a waste of time to do all that reaming and working of the hole.

I purchased a 2.3mm(.090551 inch) drill bit to see if i could just use it without reaming... When i get home tonight i will try it and follow up.

This is great news! Although, I recently bought some .0906" bits and also .0910" and .0915" reamers. I can still re-use the .092" axles for a while though.

Used the 2.3mm bit. Very snug, it definitely needs the relief hole a la 5Kids.
