Pinning Spinning Axles

Derik, One of the problems with wheels with the rollerskate hubs (.300" spacer) is that they leave so much extra axle room that your locknuts may bottom out where the threads end, instead of on the outer washer/bearing. This problem is compounded when the axle is longer than necessary. I wouldn't however, blame it on "not enough threads" because you want your bearings to rest on as much of the unthreaded axle as possible.
It sounds like you turned your locknut until it bottomed out and it started turning the axle instead of snugging up to the bearing. Adding more washers to the outside is one solution. You may try adding a tall washer next to the hanger, with a speedring next to it, and more speedrings on the other side of the wheel. Using wheels with the .400" spacers is another solution. Once you tighten up both sides all the way, you won't have to worry so much about the axle going anywhere (spinning or not). There is really no place for it to go. If you have a hard time getting the whole system tight without pinching your bearings, you may want to try bearings with precision integrated washers and spacers.
It sounds like you have the first "floating axle" Up Truck. Be Happy!

Uptrucks loose axle issue
|

Hello surfers,
I just mounted a new pair of Uptrucks. When I tried to fix the wheel with the locknuts one axle slipped loose.
I guess because the gravity wheels have spacers smaller than 8 mm. So the locknut came to the end of the thread and the wheel was still loose. I turned a little more - not with brute force, just a little torque - but that turned the axle loose. For the gravity wheels 4 washers for each wheel are required.
This is not what I would call a non slip axle. Has anyone of You guys an idea of how to fix it?
I mean I could fix one nut on one side with locktite and then use two wrenches to turn the screw on the other side. To unmount both wheels I then could pull out the axle. But that's not a cool solution, hm?
Another issue is, that the low profile speedrings have the tendency to disappear into the the axle housing. I placed large washers between the axle housing and the speed washer, that works.

Wax, Where have I ever, even once, told anyone NOT to buy a truck until until mine are done? Can't find an answer? It's because I have never said it. For the record, I don't have a release date for my trucks, and I've never given one. I'm not going to rush a product to market and make all of the mistakes that SOME vendors are making in design and execution.
You say that "Chris has been blowing smoke up peoples asses forever about his truck designs, yet they have never seemed to make it into production". The only thing up anyone's ass is big green bug - in yours. Is it possible that you make a post about something that you like, without making it an opportunity to slam someone or something that you know absolutely nothing about?
Why would anyone believe anything that comes out of your mouth regarding skateboard equipment? What exactly have you done to make you an expert on what I'm doing here in Hunting Beach? What exactly are your credentials? What have you won? What have you done?
Maybe you get a nice view from the cheap seats on the sidelines of races, but that doesn't give you any insight. You have to be a skater for that. And THAT, you are not. You lack credibility, and trying to bring me down just makes you look all the more ignorant.
My trucks will be done when they're done. People can judge for themselves, the result of my efforts. The last thing in the world that they're going to listen to, is an opinion on them from Wax.

Steve...I never said the Slayers or Splitfires were the "last Word" on truck designs...there are more in the works...Mr Chaput has been saying hold on...My trucks will be here soon for a few years now...I am sure Dan would like to skate now, and not wait until Chris's are done...thats why I suggested the readily avaliable Randal DH or the finally ready Radikal DH...Are Chris trucks going to be done soon? come on, you are so close to HB that I am sure you have a hand on the situation

Dan, I agree, get the Randal DH 160's (hangers & bases) if you've got to have something more stable right now. They work good for me.
Wax, you're out in Colorado, a long way from Huntington Beach. What makes you so sure you know what's going on out here? Your trucks are good but they're not the last word in truck design.

Dan,
Start with the DH 160's. If you want more width, then try the 180mm hangers.
BTW, there's a parking garage session near the Greenwood Village skatepark tomorrow night if you're so inclined.

I'm learning...why bigger cushions? More turn-ability? Or better return-to-center? And where can I see these spherical bearings you mention?

p.s. you can identify grade-8 bolts in the hardware store by the hash marks on the head of the bolt. If there are six lines, that's grade-8. three lines is a regular grade-5. You can also get big lock nuts like in my picture (and you don't have to get the kingpins as long as those on my trucks - they're a bit on the long side, huh? ha!)

flipped logic

In the 'standard' configuration, the highest degree of torque on the pin occurs right where the threads begin -- increasing the likelihood of shearing or snapping. 'Flipped' configuration puts the smooth/strongest part of the pin at that highest stress point, as Mark points out. Note that you typically need to remove the baseplate from the deck to put the kingpin through. Hopefully that's making sense?

Flipping the kingpin means - put the bolt through the truck so that the head is where the nut usually goes and vice versa. This is probably more important even than the grade of bolt. I haven't broken a pin yet in flipped position. I'm curious why Randals aren't just sold with that bolt configuration to start with?

"...when you're retrofitting the grade-8 kingpins, flip them around so that you adjust the truck via the kingpin nut (as this places the strongest part of the kingpin where the stress is the greatest)."
Can you elaborate? That seems illogical to me.

Randal Fuller (one L in Randal, two L's in Fuller) uses TWO DIFFERENT length kingpins for his longboard trucks (and more for streetluge) The R-II series (150mm & 180mm) uses 2 1/2" dome-topped kingpins, and the Downhill truck uses a 2 3/4" dome-topped kingpin. The Dome top is "grind friendly" but is harder to wrench. You can use Grade-8 2 3/4" kingpins in the R-II's and 3" kingpins in the Downhill trucks and put taller cushions on the top. The Grade 8 color is kind of brassy looking. The fine thread of a 3/8" hex headed cap screw for this has 24 threads per inch. Go get 'em.

top quality kingpins

I posted my knowledge of quality kingpins some time ago in this forum. Use the NCDSA search under "truck reveiws" and type "quality kinpins". The stock Randall R-II kingpins are grade 5 and 2 3/4 inch length. Grade 8 are easy to find at many hardware stores although most only stock 2 1/2 inches or 3 inch lenghts. Good luck.

randal / kingpins

Most decent hardware stores will have grade-8 bolts. They're usually zinc plated in a gold color, and the heads have six lines/marks to indicate the grade. As was previously mentioned, the threading is 3/8-24 tpi, aka "unf." A 2.5" length will work, but 2.75" gives more room for taller top bushings, thicker (flat) washers, etc. For the DH model, we recommend 2.75 or 3.00". And when you're retrofitting the grade-8 kingpins, flip them around so that you adjust the truck via the kingpin nut (as this places the strongest part of the kingpin where the stress is the greatest).
I/we have tons of grade-8's here.
