how does the loaded vanguard pump, i am 135 lbs and there is a black label vangaurd designed for 130 -160 lbs, and a silver label designed for 100-125, i was wondering if the vangaurd has a better overall ride if its kinda stiff or super flexy?

Hey Dino,
I got a Pumpkin 38" Crusier, It has mass camber, Up off the ground maby a good inch with no trucks and its super stiff for the lenth. Once you get the momentum going you can move out on the flats for .5 mile or more with a decent omont of speed. I think stiffness helps to tranfer the side to side motion into a forward momentum.
Yo gator i think most people that post here skate religously and just love to talk about it when there not doin it. right guys?. got one of your decks..great vintage skate ;^)

Pumping since the mid 70's

Pumping is a joy. It is great to get in a groove and not put your feet on the ground. I remember being surprised in the 70's that others were doing it. I thought that I had "invented" it, because I learned it in Ohio seclusion - as a natural progression from "tic-tac"ing. Try pumping while doing a tail wheelie and see how far you can go. It's fun. My son can pump on a Razor scooter.

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.

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...
