The Downhill Thread

jeepers: that's quite a price DHK. ?Honestly though, please get a quote from an engineering works.

Who are the engineering works

[Capricorn]

the guys who do machining using lathes and CNC machines etc.

 

btw: doesn't your school have a machine shop? I bet you can have it made there!

[Capricorn]

btw murray: what you think of that Micayla chick stacking on that lip? jeez!!!! ubergnarly.

[DownhillingKing]

Nope it doesn't

[DownhillingKing]

Ahhhh that must hurt!yho didnt look good at all

Cap who can machine a drop out for me

[Capricorn]

 

let me ask devon at action cycling tomorrow. he once mentioned having hangars/dropouts machined for his Xtension, which means he might know someone who can do it for you too.

 

 

 

Wonder though if there any hubbers out there who can do this sort of thing?

...hmm...

 

well, DHK do you still have a specimen drop-out? One would need to "backward-engineer" it. Then if it's a flat profile, one could get it laser-CNC'd. We got guys that our firm uses for that kinda stuff... and it's reasonable. Put it this way... I can get 2 custom rotors cut for the price that an LBS sells you 1 .

 

So yeah... if you still have an example of one, I could do the CAD work for the CNC guys.

Okay I will buy one. Then send you the old one. But what sort of metal will you use?

[patches]

I'll have to do some research as to what is currently used. I may go with that... or cos it's for a DH rig, and not for a weight-weenie, we can go with something more robust like 410 Stainless Steel, or S32001 Duplex Steel.

No. for a drop out you use a fairly soft metal. Their is logic to it. Rather have a broken drop out than a bent frame.

good call! I forgot that they play a similar role to shaft keys.

 

Well, best bet is probably to see what the manufacturers use

This guy makes replacement hangers

they are made out of 6061 ali.

Not on a DH bike as the wheel is hold in place by the drop outs.
