bike companies,less shrouded in secrecy and voodoo tech(seemingly) routinely advertize the exact alloys used in a part, 6/4 is strong enough for crank spindles and pedal shafts? ,alpha beta huh?, well i guess my axles will be a smooth sliding fit into the hanger and easy to replace with cromoly ,and i'll step lightly for a while. Oh yeah grind king has ti kingpins and sort of cheap(for ti)

Ti 6-4 is not very strong, generally on about the same terms as 300 series steels. Not good enough for axles, unless you weigh 53 lbs. and don't hit bumps.
Radikal uses a proprietary alpha-beta alloy. That's polite-ese for I don't know what it is, and they ain't gonna tell me or you either.

if the radikal or pvd axles are 3-2.5,as i suspect, breakage is more expected. Same with machined aluminum 6061 is real common much weaker than 7075, cost is very similar(of the raw material) machining cost is much higher for the superior materials,harder to cut=tougher to break,not impossible but better.

I am looking for flying pigs as we speak...I actually agree with something that Mr Chaput posted!!
working in the environment that I do the last possible thing I want to do when I am skating is wrenching my setups. Of the 4 sticks I ride in slalom 2 are now at the set it and forget it point. My main G/S and hybrid stick is as I set it up in March at the windsor superg...and I ride it most of the time. My wing is the same way...its great...put wheels on it and go...and if it aint right I just grab someones skate tool and make a quick adjustment..
I might feel differently If i worked at a desk, and if that was the case Id ride PVD or Radikal. Mabye Radikal should build a pocket-able skate tool for Radikals, that was the big thing I didnt like about mine was needing to do so much to change it around, with so many tools..(ps...I never broke a radikal when I had one)
But all are awesome choices and it is great that we have so many choices in quality slalom trucks...
I just wish it was nice enough out to hit the hills

herbn,
You might know this already, but the PVD has Ti axles. I didn't see mention of a specific type.
http://www.peterverdonedesigns.com/pvdtrucks.htm
You're absolutely right in the sense that Ti can be used in all kinds of applications but, like any material selection, it's critical to have the material and the heat treat that suits your specific purposes.
The parts that I've seen in aircraft have been Ti 6Al-4V. All this means is that it's Ti alloyed with Aluminum and Vanadium. See this page for some general information. Notice that they list a possible application as "spring", implying that it's resilent and tough, not brittle.

(the link above is just for information. I have never dealt with the metal vendor)

the truck i'm working on uses the same 13mm/halfinch wrench for both wheel and bushing adjustment.Well maybe ,i'm thinking of allen key bolts for the wheels,my goal is to make the lightest possible dh/carving truck(wide) I'm gonna make ti axles. Question for the "mass produced" truck maker(s) was it radikal that has the ti axle's? and if so what type of ti? did i ask this before maybe it was unanswered,the type of ti alloy has a lot to do with it's succeptability to bending/breaking.

Well my kingpins havent broken on my Radikals. I wish I could complain as unless they break I wont get any new ones will I?.. i like shiny stuff.
I know some skaters break Lazer kingpins easily, I never did. I cant explain it as I guess I ride agressively, though not over clackity sidewalks. My trucks vary from loose to tight...
Have to say The Radikals have lasted well. And The ones I got are 2 years old now and used almost exclusively.

I hate dicking around with equipment. I want to set it and forget it. If I can't tune it with a 9/16" wrench, I don't want to play. I don't want to perform surgery on my skateboard - I want to ride it. My idea of a pit stop is when someone tosses me a skate-key from the sidelines when I'm walking up the hill, and I toss it back three steps later. Done. I'm a complex person, but I crave simplicity. I'm not a watchmaker. I'm a skateboarder.

Great post Mark... I felt a bit like that when I first started riding your trucks. Skate tool plus extra open 5/16 and small whatever size plus another allen for the rear....... buggar to get the king pin in without cross threading after a bush change , check every thing is tight after every run........ but then I love all that. Working on, and fine tuning a nice piece of machinery is fun to me. They look great hanging on my wall and feel great under foot. I'm sure the PVD's would also. Just wish Peter would make them again.

Glen, No- you need a philips head screw driver and another wrench-- &%^$!!#$ I dropped the allen wrench and one of those wash..... Heh quit knocking my chair man, there must be $185.00 worth of screws and washers here and I can't get them mixed up. OK now where was I - Oh yeh, If the base plate screws are different there is ANOTHER tool involved.
Now If I can jus........t #$&!!!#%$ The DAM%$#@#$ base plate screws are in the way of the track thingy screws---- -BUT I WANTED IT THERE not on tne next row of screws. OK_OK_OK_OK_ All I have to do is take the base plate BACK off and then move it up one set of holes..where's the ..HEY_HEY who took the allen wrench--NO NO not the one for the seismic-- I KNOW that one works TOO- I mean the allen wrench that goes on the other screws----NO I HAVE PHILIPS HEAD MOUNTING SCREWS. I need this one for the plate to angle thingy-- NO! I DON'T KNOW WHAT IT IS CALLED.
Chuck, just don't knock anything over- I think I know where all this sh#$%*&^@ goes.
WHAT DO YOU MEAN THE RACE IS OVER- I HAVN'T FINISHED MOUNTING AND ADJUSTING MY PVD'S.
AND THEN!!!!!
On 12/23/2002 MARK MCCREE wrote in from (209.26.xxx.xxx)
I have to say that after all the dust settled from dropping all the misc. parts and wrenches(Chuck did finally bump into my chair) I had WRENCHED together an amazing set-up.
Behold- my board mounted with PVD's. John rushed over with a glassy look like I was dating a teenager and showed me the ADJUSTING ropes. I told him I could snap a bra with one hand- so he felt comfortable I would understand the directions.
I DON"T BELIEVE IT you only need one allen wrench for this excersize. You were right Glenn
After undoing the limiter (I set it up for no wheel rub --no matter how hard I turned) It felt better.
I wanted It to turn easier so I undid the allen screws that dampen the bushing. Hey -the screws will fall out if I go anymore and I want MORE. WHAT you mean to tell me I now have to perform open PVD surgery to change the bushing.
OK_OK_OK_OK I will WAIT untill those new bushings are sent to me- I thought SOMETHING in that bag of bushings I have would work--BUT NOOOO.
OK I will run the "we can all make it course" and see what happens.
"MARKY LIKES IT" THEY RIDE GREAT. Noticeably better than any conventional hanger truck. All that work and sweat to assemble them was worth it. Now I think I'll go back to the shop and replace all the steel with Titanium. No wait maybe I'll do some more adjusting-- WHERES THAT ALLEN WRENCH- NO NOT THAT ONE- THE OTHER ONE.
I have to go now.

Hey Bob, both breaks were with the front pin...and both involved trucks with older designs, which i sent back for modifications.
As for PVD's, i dont get what the fuss is....it has to be the easiest truck to work with in the world. Once you know where you want to set it on the baseplate (and there's only a couple realistic spots)and you know what angle you want it, there's nothing to tinker with at all. Just drop in the duro bushing you want and ride...tighten or loose a bit just like any other truck. Put on the width axles you want....it's easy...versatile...and very easy to clean...
and as a bonus, it looks bad-ass

Hey Chuck,
Thanks for finding that shot. Actually that is downtown West Palm Beach in december of 2002. John Gilmour was also wandering around somewhere along with "ollie"Allan Gelfand. We certainly had alot of fun. The trucks (Radikals) on my board were the original prototypes.
I will try to find the funny post of me describing how many tools I needed to adjust the set I BOUGHT from Peter that day and how many nuts and bolts kept dropping on the ground from them.

Rookies Theory for breaking Kingpins

Derik

(193.7.nnn.nnn)
I don't ride Radikals, but I know a little about steel.
If the Kingpin is made from heat treated spring steel, that could be the reason for breaking.
Usually spring steel is flexible, but not hard. If you treat the steel with heat, it becomes harder. The harder, the brittle it gets. Like a spring. If you bent a spring in the direction it's designed for, it's flexible. If You bent it crossways, it breaks immediately.
So my therory is, that the racers are stressing the kingpin in a way that the kingpin lasts. Harminonical, even turns - the kingpin takes the stress swinging.
Cracks in the pavement or sidewalk seem to stress the kingpin crossways.

So let me see if I understand all of this.
* Now my wheels are too big
* Now my trucks are too loose
* Now I need to regularly check and replace all my parts
* Now I need turn limiters on my trucks
Nobody told me. I didn't get the memo. I guess that I'm going to have to get smaller wheels, tighten my trucks, stop turning, and learn to ollie. Damn. Just when I was starting to think that turning at speed was fun.

Actually, i checked out Mitchels board at Trade street....he had his front as loose as it can be...with a clear rad shaved down about the diameter of a penny...so loose isnt an issue...Cbark made the point of the riding surface...Mark seconded that point....
I've broken two kingpins...both of them while riding around the neighborhood..not riding or turning
hard though. However, the streets in Detroit are concrete, not asphalt, and there are expansion joints and many cracks....if you dont like the BAM BAM BAM of the joints/cracks, you learn to make them part of your turn and it weakens the impact...but it puts the impact on the truck while there is pressure from the bushings....
no doubt in my mind this was the contributing factor in both my cases....No more rads for "recreational riding" for me...i'll use conventional trucks for that.
And the Rad Pins havent broken since......
it's true, it's the terrain

Mr. McCree,
My apologies. I was under the impression that the kingpins were Ti. I thought I saw that in a Concrete Wave mag advertisement. Sorry for the misinformation. Many varieties of steel are a much better choice for a part of this nature. Good.
If you don't mind me asking, what alloy and temper of steel are you using? I understand if you decline this information due to proprietary reasons.
As for your Ferrari analogy, I *would* expect the Ferrari to be able to drive down the street and hit a manhole cover or an abrupt change in the pavement without a wheel falling off. Ferraris do this just fine.
I have been involved in both on and off road racing cars and motorcycles for about 20 years. The racing vehicles that I've been in contact with are more durable than their street counterparts, not less.

Chief red beef, And "Bob";
First. The RADIKAL kigpins are NOT Titanium. They are spring steel heat treated chromoly.
You do not buy a ferrari and expect to off road and hit pot holes without consequences just because you paid alot for the car. The Talon is the truck for that.
I have seen everything from tipping the board back and forth on two wheels to full on inner wheel bite on the BASEPLATE!!to jumping off curbs -- These trucks were designed for RACING --not abusing.
And Chief, In my imaginary world, all the money I and Sparky have SPENT the last 3 years and not made back yet, shows up magically in my mail box. LOL
