Yay! you got your camera Eric! How great to finally have some 'live' pix from your skate lab.
Ok, so let's see if we can view your fine Roe pumping setup here:

My Roe/Carver/Original pumping set up can be seen here;
http://www_silverfishlongboarding_com/forum/viewtopic.php?t=22061
I'm not sure how to post pics on this site yet, but with Erin's help I'll eventually figure it out.
My other pumping set up is a Comet with DP trucks, but it is classified and photos cannot be posted on the internet at this time.
What do you think of the pumping set up in the pics linked above?

By the way Al... your S9-Sidewinders ROCK!!! I dig 'em for pumpin and carving, they especially shine on slight downgrades. When it dries up here I will finally get some more ride time! Sean you can see a pic of them in action in a Sector9 ad of the latest Concrete Wave, and here's a pic of a close-up: Hydra

Hey Al, with an emphasis on improving pumping leverage, I think using sky hooks would be great overall. Especially if you tend to pump more over the nose of the deck, your heelside turns are complimented by your toeside "lifting" off the deck slightly, and skyhooks might help you crank power off that. I test stuff for a living and my thinking tends toward 'failure' scenarios, so I just pointed that 'endo' situation as one minor trade-off. ;-) Though in fact, you wouldn't be entirely strapped down with hooks -- I'm sure the guys who use hooks regularly mountainboarding have their escape technique dialed, with just a little learning. Would be great to hear how it goes, if I can find a pair I'm hookin' up too!

I'm one of the primary developers of the Sidewinder truck, though I have nothing to do with the marketing of that truck. The new truck I'm developing is somewhat of a cousin to the Sidewinder, and will utilize the same DP system for turning. Anyway, its still being developed and has a little ways to go yet, but the prototype designs show some promise! Anyway, I'll try to remember you in the future and if I need an extra test rider some day, you might get a demo set?? Just an idea, but it might take a little patience on your part, because, as I said...they're not exactly ready and I'd like to get these axles and bushings done right! :) Maybe remind me in a few months?

To partially answer my own question...I just came across some info. on the web and it says that the Indy trucks use the 4140Crmo steel that I was talking about. So, I guess this is pretty much the best quality for the $ type of axle steel to use! Also, Herbn was some help...and I'm researching some of his ideas.

Yes, James, I don't like to think of such scenarios. I already smacked my head on the ground, once before, and it almost knocked me out! However, I'm pretty much an optimist, and I guess thats why I like to invent things... I always think there is a way to solve almost any problem,especially if its a mechanical one. So, if the shyhooks really work, it's great, but if they are still too dangerous, then maybe its best to consider other possibilites. One thing seems pretty sure, though..and that is, that the sport would definately benefit by such a product that really helps longboards get off the ground!...and land safely! :) Anyway, I guess I'll make a couple sets of sky hooks to try out, it's probably faster and cheaper than having some shipped to the Carribbean.

great idea Sean about herbn, he was recently posting pics over there on his latest truck creation.
Al, I've used toe stops and wedges but only thought about sky hooks, just to create a really positive, locked-in pump -- but now that you mention it I see practical applications jumping trail obstacles that seriously scrub speed. The bike trail I ride all the time has these really nasty 'ribbed' concrete structures just before some intersections, that are best cruised over diagonally, but when the trail's really busy you just have to roll over them head-on, lose speed, and feel your fillings rattle loose. Sky hooks might be perfect for a bunny hop there... The only trade-off I see is being locked in, cuz on my ride home tonight I hit this gnarly little rubber washer thing that stopped by board COLD, but I was able to hop off pretty gracefully. With the hooks it might have looked more like a snowboard flip, without the snow... :-O

Hey Al, you might want to make a post on that in the board building forum. HerbN makes his own trucks and he'll definitely know what to use.

Another question, but differnt topic...axle steel. Does anyone know if SAE 4140 chrome molly steel is good for longboard truck axles? Or is there better steel available?

Anyone know how well the sky hooks work? I think the ability to throw in a few jumps while pumping would be pretty fun! If we can compare longboarding, both downhill and pumping, somewhat to skiing, this 'airborne' side of the sport of longboarding should be developed. Every skiier knows that getting a little air every now and then makes that sport all the more fun...and this should also translate into longboarding. The problem is how to make such jumping safe on asphalt. And of course I'm not talking about trick riding, ollies etc... which are generally low velocity jumps. I'm thinking of some pretty fast speed jumps, say in the 5-10mph range. Any ideas?

Just checked out the new sport centre car park, really smooth, shame about the massive humps half way down!
Anyway somewhere new is always nice and we now the manager so thats cool.
The 180's are quite hard work, but i can make speed quite quickly, at one point i was doing s-carves and pumped the rear more than i would normally and found speed in a way i didnt know about!
Now i sort of understand the rear accellerator thing now, but although it felt great and i wasnt getting the cramp in my front foot as usual, i couldnt get my footing the same again????
I'll get it, more practice, more fun.

Heavier Original Springs

One thing you might want to try SS, is asking Scott to send you some heavier springs for the rear Original. I would imagine the Carver front with the Original rear might be a little to squirrly to actually gain a considerably fast top speed. It may accelerate very well, but top out quickly. Scott has heavier springs for heavier riders, and making the rear Original a bit less responsive yet still very turny could do the trick...
As far as a cut down CX goes, I may buy one and then ask a machinest by me to cut it down and put 8mm axels in it... This could get very interesting...

Jamie, that's a great idea! Revenge trucks use a stock kingpin like that, all smooth, just a little threading. "...a longer bolt(3 3/4") cutting it down, leaving about 1/2" of thread for the nut..." Hope to hear some cool commuting stories down the road -- make sure your workplace has showers ;-)

originals front or back...

Once you get Originals dialed and get accustomed to their amazing turning radius, you'll be carving up any steep or mellow slope. The 'fish' shaped Original deck allows huge wheels without bite. I've got a few sets of the 6's, and even use Originals as a RollsRolls front truck, to give that super stiff deck at least a chance to be a pumper ;-)
I've had reservations using Originals as front truck for LDP, and this comes from busting two baseplates rather quickly a couple years ago. For a long time I was discouraged, even though I loved these trucks they didn't seem to hold up to the long flat pump sessions. HOWEVER, it turns out there were a couple gaffes on my part. One is, with Originals you must check the bushings to make sure the main pin hasn't loosened too much, just as you would check the c-clip on Seismics or tighten the kingpin on a Radikal. The other is just to keep the bushings lubed. I was riding mine on 10-mile flat pumps continuously, several times in a row without double checking and adjusting. With just a little care they last forever. And if you're mostly downhill carving, they take much, much longer to require maintenance. Scott at Original replaced 'em right away and I'm still stoked on their unique, surfy feel. Sounds like an interesting test what SS is doing with an Original on the back - I'd be curious to hear how well they propel you forward, I haven't tinkered with their different springs but the silver ones I found made me work a little harder. Still they have a very cool surfy feel. I can see why they're a preferred mellow cruising truck when it comes to flats.
For LDP I still depend a lot on the CX, it holds up without any checking, for at least a 26-miler, so I can make it through a marathon non-stop. Usually at least one component, the top or bottom bushing or pivot cup are thrashed by the end, but it makes it to the finish line!

cut down CX

hey Sean, I asked both chicken and geezer about a month ago, and both of them could cut down a Carver CX, but I just haven't followed up on it. I'd say go for it! I've tapped out my slalom budget for the immediate future unless I can sell a kidney on eBay. It would be an interesting experiment at the very least.
I don't think modifying the Carver C7 or the RTR would be worth it though --IMHO they don't snap back to center fast enough for slalom. Unless you could get a fatter, snappier spring in the inside of the RTR. Those guys have modded a couple parts around the main spring for me which should make them last longer on LDP rides, I'll be testing next week hopefully!

If the Carver CX and C7 are both excellent trucks for pumping. And down require to be cranked over very deeply (such as an Original S6 or Exkate 101), would a cut down version work well as a front slalom truck? I would think definitely yes. The CX would probably work better because it turns harder from swiveling (or turning) to the side (the baseplate). The C7 relies more on a sharp deep turn... The same could apply for the RTR carving truck as it does for the CX... So why not? Reasons?
