Really?
Ti ain't good enough for Bolts, Axles...Springs...etc.?
WOW!
Really?
Well, it's just outta sheer luck that I PERSONALLY tested such items FOR A LIVING at Lockheed...shear tested...as in...
Tested them to Ultimate Failure...then performed FA/FEA and CA...which was always a "Quality" of materials and/or manufacturing issue.
You know what's Funny?
You fly on aircraft...alll day...held together with Ti...and LANDING ON Ti Landing Gear items...and that bird is assembled with TI fasteners that are the HIGHEST LOADED parts on the whole damn vehicle.
Thank you Boeing!
Then there's the F-18...slammin' decks all day...on Ti castings, Forgings...etc. Not to mention all the Ti components in the LANDING GEAR. (Should be called "Crashing" or "Slamming" Gear!)
Anyways, I've got Ti stuff on my KX that's been used for 2 seasons of Pro SX/MX...two "X-Games"...and then some.
Hell, I've got Aluminum fasteners that're better than some of the "Ti" crap that some of you must have...this statement based on some the the things that have been said, in here...by some of you, about what your Ti stuff Can/Can't do.
So, in review: Let's not go talking shit about things that are "Crap" due to the extremely POOR characteristics of their "make-up" & then go making silly statements with misused "words" (See Shear vs Sheer).
Next-Up: Someone can tell me all about Composites and how Carbon-Fiber isn't "capable".
I'm jus' sayin'...

And that carbon fibre stuff - brilliant as long as you use good epoxies. If your glue is shit, your ride will split.
When I worked for Viking metallurgical I'd cut a test ring off the turbine rings I made and they sold these turbine rings to Boeing. Another machinist would take that ring and cut a couple 5-6" sections from it, then machine it to pencil size with threads on each end. Then it would go to testing and be put in different machines and pulled it apart. I never saw a test where they tried to bend it.
It was 30 years ago, so I don't remember a lot about it, but I do remember they used laughing gas in one of the test.
I also made a couple Ti crowbars that were pretty brittle and would snap when I applied to much pressure.
You need to select the right alloy for the application. Most likely failures seen are because someone didn't do their homework.
John Ward, a brilliant American racing car engineer (think AAR Gurney Toyota GTP car) once told me 'parts don't fail. People fail'
Think about that, then just look at wikipedia and you'll see what I mean.
There are 38 grades of titanium for pete's sake!

Now if the materials have gotten better today, that may not be the case, but years ago, they changed those heavily stressed bolts often.
It's the Quality that counts: our Ti Honda M12 foot-peg mount bolts are made from 180kpsi rated material.
I run'em in Baja 'cause they're stronger than stock & less crusties from salt-water.
I ain't no Pro...my riders are.

I always get those words crossed up.

I mention the Foot Peg bolts due to the amazing fact that they "Make Sense" on all levels...
1. They save a shit-load of weight because they're SO huge.
2. They don't cost even 10% of what an Axle costs (Yet they save damn near the same amount of weight: The complete 4 bolt kit, that is)
3. More than a few people have had problems with said fasteners "sticking" (never been removed and lubed/reinstalled/serviced) and or coming loose (Been greased and never torqued correctly) depending on who(m) you're dealing with...and where/when...
Btw, combined w/ Ti pegs they save more weight than a rear-axle and still COSTS LESS: $239 v. $745 (Complete Rr Axle kit).
Please feel free to tell me how expensive that rear axle is and I'll say, "Yup!, That's why we make them in VERY limited numbers and for very few Teams!"
Most people can take plenty of weight off in all the right places and get fasteners that they'll use for YEARS for about $2K.
And, again, "Yes!" that's a lot of money and "No!" you don't have to buy them and "Hell, YES!" I run'em...because I can.
On the other hand: I am looking into "Sub-Kits" for folks that can get the best Bang for their Buck.
I'm jus' thinkin'...
The material for our M12/12.9 rated bolts is 175kpsi rated and that material is a virtual "Steel Replacement".
Thank you.
