Home made dog bones.
knobdoodle
I've never had anything to do with them but I'd been under the
impression they'd be cast unobtanium with nitride-infused micro-peened
diamond-coated surfaces and I was just looking through some forums and
I saw a bloke just saying you could knock up some custom-sized ones
with some bits of steel, a drill and an angle-grinder.
Anyone made their own (or know any tales of doom from people who
have?)
Cheers ..... Clem

A guy in the UK makes them for the SV from high grade stainless steel.

The ones on the FZ1 look like 3mm steel - they must be a tension member
cos they look mighty flimsy to take much compression without buckling
You would get a good idea of the material by scratching it - probably
mild steel, unlikely to be hardened as that would increase the risk of
fatigue failure???

The only dealings I have ever had with dogbone links are Kouba lowering
links. They are pretty light and don't look particularly exotic.
According to some blurb I found they're made from 6061-T6 Aluminium
alloy. Wikipedia says this stuff has a tensile strength of at least
42,000PSI.

I think you've discovered that steel is probably adequate for a
Clem-bilt job.

Christ no; I know as much about metallurgy as I know about making women
happy!
I'm VERY impressed by the story though; it sounds like an excellent example
of a jury-rig and, coming from a long line of people who'd do almost
ANYTHING to keep going rather than admit defeat, my hat is most-definitely
doffed in his direction!

I agree
T6 refers to the temper or heat treatment applied to the base material -
The most common high strength aloominum would be the 6061 'aircraft alloy'
From yer Materials Handbook; And not too specific - there are sooo many
varieties of steel
Youngs modulus; Yeild Strength;
6061 T6 68900 MPa 276 MPa
Mild Carbon Steel 210000 MPa 386 MPa
In general the steel is stiffer than the alloy and you can pull it
harder before it stretches, it's about 3 times heavier and 1/10th the price.

Loads of them on american ebay for just about everything. Stick in lowering
links in the search box.

I think you'll find it's aluminium for lightness rather than strength
- I can't say as I've ever read anything to indicate they need to be
super strong, obviously as a suspension member it needs to be
reasonably robust, but none I've ever seen have been super big or made
of unobtainium AFAIK

...and come up with motorcycling's equivalent of low-profile 4WD
tyres. That so many outfits offer such abominations is testament to
how simple they are to make.
The ones Kawasaki and Suzuki tend to use are literally just a pair of
lengths of 3mm steel with M8 clearance holes at each end. Could knock
them up on a mill in a matter of minutes.
The single chunky dogbone Yamaha, Honda and Triumph tend to use is
more elaborate; alloy (on both my R1's they have been, at least) with
pressed-in bearings. Bit of machining involved there, but still
doable.
All operate in tension, so there aren't too many demands on the
metal...

Pssst. We have a $100,000 washing machine at work that no one uses.
One of the guys threatened to buy a dryer, and the operations manager
nearly had a breakdown over that and then resigned.
All the workshop guys did their 3 days training on it, and now no one
wants to use it.

I looked at such things for the NOrge but was told they would make the
centrestand unusable.

Fulliautomatix
At some point it would be unusable
It is guaranteed to be harder to get the bike up on it as you would be
starting with the stand more horizontal and moving further vertically
A bit of triggernometry and a tape measure would tell you if it will work
Cut down the stand as well?!?!?!!
