22mm axle

[jato]

presently on the lookout for a 22mm axle around 285/290 long... i see some motocross bikes have them but surely not 290 long. its for a track bike- the swing arm is made for a 20mm axle but apart from being puny the slots are quite loose (maybe 20.4 or so) . 25 is real tempting but that'll reduce valuable clamping land area. 22mm will be a good solution... i could make one but if they are available oem that would be easier/cheaper/better? any thoughts?

In the old days you'd go to a wrecker and go through their crate of axles...

Are stepped spacers an option ?

[jato]

The wheel previously had a 25mm axle so i'll be making some hard anodised stepped spacers (one under the cush drive and left bearing, another under the right bearing and shouldered against the caliper hanger) . the easy way out would be to ignore the clearance in the swingarm slots but i'm keen to keep it all strong and good fitting. i suspect a good axle would be heat treated to a "half hard " state hence the anticipated cost of making one being 2 or 3 hundred.

the only axle I've made from scratch was 20mm. Turned from a broken HQ Holden half-shaft.
Never even considered hardening it.

When asked we said it was made from HQ quality steel. Blank looks all round.

this is a early ish YZ f one as you say not long enough

I would look at something like a CBR400r or NSR250r they were 22 and should be wide enough.
if you ask nicely simon at Good parts will look for you and confirm sizes.

Cheers Husa , i'll send an email just in case... if no luck i reckon a 25 will work good if i make up some new sliders so we can get a good clamp on each end

It occured to me the other day did you look into swingarm pivot bolts?

[jato]

Sorted now ta - found a nice ducati 25mm axle and modified the swingarm then made new axle sliders to regain clamping area. i'll start a thread for the bike when its nearly done

That's taking most of the fun out of it. We need to see it at the early stages of construction in order to point out perceived faults and steer you down blind alleys.

Which is the reason I never encouraged visitors at my last place - where I frequently had a build underway.

In my experience there's nothing like a frame in a jig to bring out the acquired prejudice and uninformed opinion of an unwanted visitor.

Same thoughts here - i sometimes see people partway into a build and 101 new "suggestions" are offered by every facebook expert ...

I was hoping to make it up next November as our biannual trek,. But not this time sadly.
Maybe time after.

Then I can criticise to heck.
But unlikely.

Especially if Joy makes another one of those bacon sarnies.
