Does anyone know if machining down 14mm axles would make them weak ?
THANKS

It's been done in the past. Two flats ground into the axle. The biggest problem is wheel nuts stripping their threads.... The way to get around this is to just grind a very narrow area to allow for the dropouts, and leave the outer ends of the axle untouched :)
I don't think you'd get away with it if it's a hollow axle though, I'm not sure there's enough material in them to stay strong enough.

Thanks mate, thats exactly what I needed to know,
Cheers

i was always on the asumption that axles are hardened ? so cutting notches would leave a stepped area of non hardened steel more prone to snapping in that area
itl probably be ok , i wouldnt put pegs on it though

The first Oversized (and Left hand drive) hubs I made had 12mm axles. I didnt wanna cut the frame at first so I ground flats in the axles that were a tiny bit wider than they dropouts (just like Rob said). It was only really the axle threads I took off, and the peg still had the support of the larger cones and bearing behind it.
Id say cutting the dropout is always best, but if there is a reason you dont wanna do this, flats on the axle aint too bad, esp if youve got spare axles.

my mate had a shimano hub on his cruiser that had factor notched axles for the 10m dropouts but keeping it a 14mm axle
arnt they surface hardened like unsealed pedal axles though ?

I can't be arsed with that now I can't believe how hard it is to find some 10mm 48's with chrome rims, has anyone got some?

can get you a set of nos hubs if that,ll help peregrines :)
