stop pumping each other with your wood or fiberglass, if you like G&S (post neil blender, if you even know who he is), and start skating. its the only way to learn. go hurt yourselves and learn, its the only way, as i said.
to those on this message board under 10 i apologize, but you should be doing your homework and studying. more than likely you won't be a pro so you should edumacate yourselves!!!!! and enjoy your skateboard in your spare time.
SKATE AND DESTROY!!!!!!!!!!!!!

Thanks for your info, PSR. I am trying it, but the moral of the story is I gotta practice. I find the best way to practice this is by going back and forth on a vert ramp, just by pumping. I am able to do it, but I just am in awe of the people who look like they are going super slow and are able to hop right on the coping - like I'd know what to do if I ever got up there!
Thanks for the help and I'll let you know how it goes. At this point, I am a 3 out of 10 on the pumping scale I think..

Jer,loose the 'jump' bit in your quest for good pumping.Keep it fluid,not too quick(well,tight spots require quick moves,so..)or jerky.Be low and soft before the tranny curve,and pump thru(get taller)IN the tranny curve,being ready to retract as you get into the Vert.If your line tends toward working the horizontal curve(vs. halfpipe,which is all done on the vertical curve),keep some extension left to thrust against that curve.Speed is key to getting the more horizontal lines and working them well,as at that point,you're in the more vertical realm,but travelling across the lip,not just up to it and back..If you look at a well shaped bowl,you'll have two main curved lines to draw from,the 1/2 pipe line(up+back),and the bowl's curvature(around the top),but it's usually some line Between those Two that you actually ride.The trick is to extend in the tighter portion of the curvatures,and retract if you start going at a lesser curve.One other thing is wheel choice.Ride a fast wheel,one that Can Slide,but has some Grip for steering corrections.I personally like using 95A-98A (bigger than 63mm) as those durometers have the best blend of speed without being too slidey or chalky or stiff. That may differ for you depending on surface smoothness or tempature at your bowl.Hotter/smoother you can usually go hard[er],colder/rougher/slicker usually means a bit softer wheel(even down to 92A)to keep it smooth and turny. To find a 'good' line,bring a grease pencil,and 'tag' spots that flow well,and work a line out from those reference points.After awhile,you'll have a chart of 'sweet' lines to use.Erase those marks if other's ride there,but know where they were.That'll keep your line yours,and not mislead someone who rides differently than you. Keep at it,stay loose,ride fast..

dino, i think you are off base on this one.
yes, a rocker deck or drop thru deck will get you closer to the roll center, looses leverage, and be more sensitive, etc.
but it's a leap to say that offers pumping advantage.
Luca, the guy who won tight slalom at MB, was on a higher than average setup.

Well, practice and practice... Here's what I have learned, and if anyone can give me some ideas of what I am doing wrong, let me know.
As I drop in(Still not good enough to get a good pump on the drop in), I bend down and push down on downward parts, then as I come to the transition, I kind of jump and squat. All at the same time, I carve and at the top of my carve as I come back down, I stand up(Hence, pushing on the board again). When I come to another transition, I bend down and jump a bit, but that's when I lose my speed and don't know why.
I am going out as much as possible to practice... Is this just something that comes? Thanx

Negative camber helps
|
|
On 12/4/2003 Dino
wrote in from
(64.75.nnn.nnn)
I have a deck I made with negative camber and it's a great pumping board! Why? Because your center of effort (CE) is nearly even with the pivot point of the truck hanger.
The higer the CE is from that pivot point, the longer the moment arm of force. In other words, you have to work harder to pump because the further out you get on a lever, the further the lever has to travel to do the same work.
Try pumping a deck with really high riser pads and you'll see right away what I mean.
Yes, I know that a longer lever offers a greater machanical advantage, but looking at it over time, a shorter lever moves relativly faster which equates to a quicker pump with better output to the wheels.
What propels you forward is the essentialy the same principal as a sail tacking upwind. The wheels act like a keel and offer resistance to the side induced force of the pump action from the foot. That energy has to go somewhere and through a complex mix of slip angles, wheel rotation and hanger angle it moves the vehicle forward.
I've spent hours thinking about the dynamics of pumping. These are just my observations/hypotheses, and I offer them up for all to play with in your own designs.

Hey Dave & G7enn,
thanks for the replies. I am around 160lbs. But I'm kind of looking for a big, all around cruiser/liquor store runner/bankrider (revere) deck to ride around on. My current quiver consists of a couple cruiser decks that i can pump around town:
A fairly flexy Surf One 38" (Woody) deck
A really flexy 47" Original Skateboards deck (with the Original trucks)
And a big fat 12" Skaterbuilt that I've been using on the banks & skateparks.
So I'm thinkin', all I need now is a BIG deck to fill out my quiver..
Or should I skip the Ed & go with something else? The Loaded is a tempting....

Drex,
Unless you are one heavy dude, why not get a more springy deck? Loaded, Fiberflex and (of course) Pumpkin are worth looking into for a pumping machine. If you are in the 150-175 pound range, a Loaded Superflex will pump all day for you.

Last year I did a lot of experimenting with which trucks worked best for pumping on a 38" Fibreflex pintail. Of course, while this board is a lot smaller than you are talking about it does have a fairly long wheelbase, probably equivilent to a 46" double kicked deck.
Initially this was set up with Randal II 150s, this seemed like a fantastic pumping board until I tried a friend's similar sized board with Seismic 157s. There was just no comparison, the seismics just made keeping the board going on the flat almost effortless.
After this I tried a set of antique Indy 151s, they were a slight improvment but I ended up buying a set of Seismics. I later improved this setup even further by replacing the back truck with a Tracker sixtrack. I did this because it sometimes felt like the back of the board was swinging to far into turns. The tracker cured this without effecting the pumpability.
I'm talking about the later plastic seismics here. They also have to have the soft yellow springs, red springed seismics are useless for me and i'm pretty heavy.
It sounds like a mismatched (one 30 degree, one 45) pair of metal seismics might be the ultimate setup for my pintail though I suspect you'll need all the turning you can get on an Ed Economy.

Thanks for the help - I guess the moral of the story is practice makes perfect. I've got it down, just not as good as some guys I watch. It seems as though they are going at a snails pace, then they are able to hop right on to the coping. I feel like my speed is amazingly fast, even with my downhill background, and I barely reach midway up the vert..
Anyway, thanks again for the help.

Hey, I'm (slowly) putting a big board together that I'm hoping to use as a bankrider/city cruiser. I'm hoping I'll be able to "pump it" around town. Here's what I'm thinking about getting:
Ed Economy Streetrider
Gumball 78a's
Seismic 180's
Biltins
Will it be "pumpable"?
thanks

I agree with wax that Dan should do a How To Pump video clip....I just love the way I can get my Bozi Mad Bomber rolling quickly through the streets when I utilize the new metal Seismic trucks! Plus, u r right about Dan Gesmer being a talented skater...and he makes some downright fun street carving trucks!!

I was in our shop today, and some kids (flippers), were checking out the seismics, they asked a few questions so I brought them back to the computer and showed them Dans newer video clip (4 wheels down I think)...after a few brief seconds of giggles one of the brighter kids noticed how fast he was going, just gliding and not pushing...they were perplexed by this pumping thing, and not just going straight, doing 1 trick then starting over again....they were blown away by Dans skill, and were instantly wanting to learn how to pump, so I grabbed my comet with seismics and took them out front for a lesson...Great fun, they all smiled and laughed, but each boy learned a little, and they want me to teach them more...Dan should do a how to pump video clip...

In 1989, when almost nobody cared about this subject, I wrote an in-depth how-to on pumping. It almost ran in TransWorld Skateboarding magazine, as a followup to a piece I wrote for them on basic carving technique.
I've been meaning to update the article but haven't yet made the time. The original text is viewable on the web at the following URL:

Over the year I have been given alot of slalom imformation on how to improve my pump. # 1. Pump up a slight uphill. # 2 Find an empty parking lot and pump front and backside performing laps in a circle. # 3 line up 50 cones 6 ft apart in a straight line,run through them and then repeat the process over and over until you can pump no longer.

Jer:
Keep practicing and you will get faster with time.
If you are on small wheels change to 60mm or larger.
Powell bowl bombers 64mm park formula is a fast wheel.

Slow pump

We usually use a pretty short distance from the line to the first cone at the DC outlaw races. 4 pushes is all you get, so like with Cyberslalom, having a slow speed pump is key. I've found that there are at least 3 distict types of pump I use in different places in a course.
1. the "compress and extend" pump. For GS courses, an at the beginning of most courses. As you set up for the turn, compress, and explosively extend as you apex the turn. Works pretty much the same heelside and toeside. Big arm swings.
2. The regular aggro slalom pump. This is one that feels like it works once you've got some speed happening. Remember to keep your center of mass over the fall line, more or less, and never underestimate how much of your power is coming from your arms. Curt Kimbel watched me and told me to work on amy arms, and it was like the missing link.
3. The frantic thrashing wiggle aka "the Gilmour" Combine all the above, and do it really really fast through tight cones.
I recommend setting a cyberslalom course someplace which is very gently downhill in, and uphill out, equal both ways and remember to use you knees way more than you are now. Be in stance so you can attack the first cone, hard. Keep trying.

(65.221.nnn.nnn)
This last weekend I ran a cyber slalom course with a few other guys. My problem is with the limited kicks before entering the cones I am unable to build up any speed. It feels like I'm stuck in low gear the whole time. When I took a 25 foot run at the same course I was able to generate significant speed even while going up hill.
Does anyone have any suggestions, besides practice, for how to get the slow speed pump going so that I can accelerate through the whole course?

Jer if your question is simply, How to pump? A Bowl or Transition.
Think of compressing on the way up and decompressing on the way down. Bend at the knee's not the back/waist.
The timming of this is critical just like pumping a Slalom board. Out of timming then it slows you down. Don't try do do it all at once either(if you reach the maximum bent position to quick you still create force against the wall your trying to climb).
For example: if your riding a Bowl with an 8 foot wall then slowly bend your knee's on your way up. Make your (kick)turn or carve then extend (decompress) on your way back down.
Your are trying to create as little resistance as possible on the way up and as much as you can on the way down. You can also swing your arms slightly on the way up and down to help you get a feel for the direction and transition. Try to limit un-nescessary body movemment, (this detracts from the forward momentum).
Good Luck.
I hope this helps you out.
