Chaput Truck Alert

You can't flip it. Check out in the pictures how the axle is offset...that will hit the baseplate if you turn it over. To get stability out of them, I think you'd just use a really slack kingpin angle.

How much riser do you use underneath these trucks? I know you use different baseplate angles to avoid wedged risers, but surely you must lift 'em up atleast 1/2" to avoid wheelbite. Just curious how much riser you use to avoid wheelbite with the BigZigs.

What about flipping them, not over, but around, placing the axle on the other side of the bushings, more near the front pivot?
Would that work? And if it does would it do anything?

**EBasil** · 11-02-2006 04:19 PM

Oh! Yes, you could do that: it's symmetrical. You'd get wheelbite, possibly even before getting a wheel on. If you did it on a speedboard with cutouts, then it would work to lower the board and shorten the wheelbase, but should otherwise work the same. aht might lead to hitting the "top" pivot on things sticking up off the ground... I just say "No", like Nancy Reagan woudl want me to. You don't want to lower a slalom board, anyway.

If that design were adapted to the Liquid II design that's rolling around a few places now, I think one would just do the drop-through to lower and I still wouldn't want to get that top pivot any closer to the ground.

Well, it's still nice to know the option is their, for whatever reason.
Maybe an emergency hill bombing situation?

**Directive0** · 11-02-2006 04:51 PM

no... just no...

Slalom boards bomb hills just fine as is.

**Slim** · 11-02-2006 06:17 PM

Well, as long as you keep turning they do fine up to the 30-40mph range. I don't particularly like narrow trucks at speed if I'm just bombing it. Some guys can do it, sure, but clearly most people are more comfortable with wider, lower trucks at speed.

Some spy photos from the proto-line at ChaputLabs. Looks like some slack and steep baseplates in the mill bay, and some dude using a bandsaw for a workbench.

mmmm...... fresh milled aluminum goodness.

**king edward** · 11-02-2006 11:18 PM

one can't help but wonder how much pie was consumed in the manufacturing of theese trucks..

To be sure! And for those people there are more suitable options currently available and even fourthcoming Chaput created offerings.

i kind of wished i had paid attention to chris when he was showing us all the cad drawings at kenny mollicas house.... but i went to bed instead...

still got the sperm suit chris? that thing was freaking funny as all hell

**oldnbroken** · 11-03-2006 02:24 PM

Pie? I think that's the fat guy on the other coast.
From the looks of Chaput he doesn't eat tons of pie.

I'm beaming right now. The first of three races here in North Carolina is now in the books. Chris Barker was the only racer who I had given trucks to. He only had two trucks, a front and a rear. He only had a couple of days of testing on them prior to tonight's race.

He won the race on them!

The Fyre Trucks are now batting a thousand. Okay, maybe Barker helped out a bit but still...

**k-lee** · 11-03-2006 10:59 PM

I just have to say that I found this thread for the first time today and I already know exactly what my next skate purchase is going to be. These look like the high tech slalom trucks that I've been holding out for. It's a good thing I'm a patient person, otherwise I'd be going completely insane right now. Any ballpark idea on the ETA/MSRP for the machined and/or the cast versions? I just need to satiate my curiosity for the time being....

Thanks for keeping the innovations rolling Chris, skateboarding would not be the same without your imagination.

where is this Chaputlab at? do i have to find a golden ticket inside a pair of pink gumballs from milehighskates to go there?

No, the golden tickets come in the Biltin tubes.

I imagine that metal on metal will make the trucks ride rough. Is it noticeable? If so, how will you solve this?

If you don't mind me asking, what design software are you using?

I had wondered the same thing before I had ridden them. The answer is "no", the ride is not rough at all. Radikals, GOG, and PVDs all have metal to metal pivot bearing systems ("bearings on bolts in two places") too. It appears that it each case, the rider's knees, shoes, board, wheels, bushings, and risers (if any), absorb any shock that would feel harsh.

These may feel different than that of a truck whose hangers sit on urethane bushings and have a urethane pivot bushing, but the feeling is one of precision and not slop. Slop is the enemy of traction and control. Slop may have a nice, familiar feeling (like power steering in cars), but ultimately it works poorly when performance is needed.

I use Solidworks 2007 Professional and COSMOSXpress to design and test in, but it's the "real world" that tells me whether or not they work. I literally stare at boards, wheels, and trucks for hours, looking for simple, almost obvious design changes that can solve problems inherent in previous designs. The fixed pivot concept has been around for years, but the timing and need to distill it down into a viable and low cost solution is more recent. Some of the ideas come as a result of "fixing" other truck's design flaws. You may not have noticed, but there are no threads anywhere in the hangers or baseplates. Everything is done with simple holes. The pivot pins, axles, and kinpins are threaded steel, and use the standard 5/16"-24 and 3/8"-24 locknuts so that the 1/2" and 9/16" sockets on your skate-key work. There are already evolutionary extensions of my basic design in the hopper. Wait until you see the ones with 5 blades, a pivoting head, a sensor strip, ergonomic handle, and compressed shaving cream dispensor...
