More thoughts: I don't mind the spin-axle ban, but only because I don't have any. I've always wanted them, but couldn't fork over the money. Do they have an advantage? Not having them, I always thought so.
I do like the idea of keeping buttboaring cheap, but when you add up the cost of leathers, entry fees, and especially travel, even buttboarding becomes expensive (though still a fraction of any other type of racing).
No matter how they change the rules, it will still be fun. Even if they made me ride my 36" Alva and Indy trucks, it's the close racing and parity of equipment that will keep it challenging. What they messed up on was restricting the LUGE class to eliminate pegless luges. I think the luge class should represent what is fastest, and should remain on the cutting edge. Limiting the design of a buttboard makes sense - it's a spec class, but in an "unlimited" class like luge, let the ideas fly!
In other news, I tried to make a 3/8" flexible buttboard (3 sheets of 3-ply 1/8" birch this time instead of the usual 4) this weekend. It seems to have come out OK, but it doesn't flex as much as I wanted. My friend "Catfish" says perhaps a balsa core would work better. Anyone ever try that? I'm now considering drilling some holes in the deck to make it more flexible, but since this is an irreversible opperation, I'm hesitant.
Got my Flashbacks yesterday. I've got sorely bruised/cracked ribs (over-rotated a backside air) so it will be at least a week before I can try them out. Nice looking, though, with a really wide contact patch.

All the sudden I'm wondering if my R2s with 8mm axles are legal. I had the axles replaced because I bent one (the R2 axles are the softest axles I've ever tried). If I replaced the axle with 8mm chrome-moly, does that make my trucks illegal? I hope not, I'm just trying to get over a weak limitation in the truck. Kinda like replacing the kingpin with a stronger one, or replacing the bushings with ones that don't crack, etc.

Duane, that would most likely be considered a custom truck and would not be allowed. The rules are dumb. Even after you learn about the reasons for the rules, you'll still be wanting more sensible specs for building a safe and effective board for laying down on. The basic premise assumes that guys are going to go to a skateboard shop and be able to find all the equipment needed to make a great board. How many skateboard shops do you know of where you can get Randal Luge Trucks, Moes, R-IIs, a good choice of 70mm wheels and a buttboard?
It is fear-based rule making. They fear that the boards will be too much like a luge and not enough like a skateboard if they ease up on some of these limitations. They don't want some poor kid from a third world country to feel bad if his pool board doesn't appear good enough to race on.
The truth is, a lugeboard is an excellent opportunity for riders to gain access to streetluge and other downhill sports and a 48" x 12" board with only 4 70mm wheels is never going outgun a well designed and more unlimited streetluge on a decent course. It's a lot of fun and can be a great class of luge, especially if we accept it for what it is becoming and make more sensible rules.

No spinning axles: a stupid rule. With the lack of 12" wide trucks out there that are stable, the top competitors will just get their Randal luge trucks modified, net effect zero. The luge trucks are worth running for the width and good 8mm axle. A low-cost option which should be allowed, but is it ? would be to modify low-cost trucks (RII 180), maybe 35 degree base in the rear, with luge axles and spaced wider. Lighter too. Are franken-trucks like this allowed ???

Dave, I've used the Indy 215 and Invader Trucks for a few years, never had any problems... I thought it is not really neccessary to switch to the R II's. Finally I tried it and after a while I recognised a few advantages concerning stability at higher speeds and especially better handling in hairpins because it's posslible to loosen the setup a lot more without having disadvantages at higher speeds. I've tried to flip the hanger because I've read it a few times in various message boards, but for me it did not have the expected effect... I've changed it back. May it works for others. Ok, hello to all others out there. cheers Tommy

hey chris, i like your 'lugeboard' proposal you made on the other forum. One thing though, i think the 12" width is just way too narrow, should be upped to 14".
I am skinny guy, and on my hakka concave, i sit on my thumbs all the time..

The 2002 IGSA Rules from http://www.gravity-sports.com
The notable changes are that trucks with floating axles have to have the axles prevented from turning and that there is an underside "clearance" rule rather than having rules that state which methods of truck mounting would be acceptable or not (drop-throughs were formerly banned).
CLASSIC BOARD SPECIFICATIONS (Buttboard)
The BASIC PREMISE is that any rider should be able to put together a competitive board from skateboard shop supplies for about $200 complete. A rider may spend more on a board if they wish, however, advancements, which require a higher investment to be competitive, will be banned.
A. DECK: Must be made of wood. The deck may have molded features such as a kick tail, but must be one piece. It may be any shape within the size limits. Nothing may be added to the deck except for the following:
1. Foam padding to the top.
2. Non-aerodynamic stiffeners to the bottom.
3. Skateboard-type grip rails underneath.
B. WEIGHT: The complete board must not exceed five kilograms (5Kg / 11lbs). This rule will be strictly enforced. A 1kg allowance will be given for variances in the accuracy of scales.
C. LENGTH: One hundred twenty-five centimeters (125cm / 48”) maximum.
D. WIDTH: Three hundred five millimeters (305mm / 12”) maximum.
E. TRUCKS: The trucks must be lean steer activated. They must be commercially available* skateboard trucks. Rolling axles are prohibited. Trucks with rolling axles that are modified to eliminate the axle from rolling will be allowed. They must not exceed three hundred five millimeters (305mm / 12”) wide, as measured from the outside edge of the axles. The board must use exactly two (2) trucks.
F. BEARINGS: Standard steel 608 skateboard bearings only. No ceramic, Mini-mizers, 9 balls or other high performance or exotic bearing types.
G. WHEELS: 70mm maximum skateboard wheels only. They must be commercially available*. The board must use exactly four (4) wheels.
H. RIDE HEIGHT: A minimum ride height of 8 cm (3 1/8”) is required. This is the lowest part of the board from the ground and includes rails, stiffeners, bolts, nuts, etc. It does not include the trucks or the truck mounting hardware.
*Commercially available means the product must have been distributed to at least 24
people outside the company.

I ride a Indy 215 in the front and a Randal spin axle, flipped, with 28 degree base in the rear on my mini-speedboard. Very low (about 3 3/4"" to grip tape with 83mm wheels). Turns very, very well with stimulator and hardcore bushings. The same set-up would work well for a buttboard, I think. I, too, have eyed the 219mm Tracker, especially cut down a little with a 205mm wide replacement axle. The tempting match here would be a Randal luge truck in the back, 12" total front and back track.

ryan, see this
http://www.hugh308.homestead.com/tutor_longboard.html
also, mario takes two .25" ply, glue them together using a jig to get the concave.
regular maple decks, are glued together plys pressed in a mold.
Dave, I only tried RII flipped, (from what i have heard its a popular setup), would like to see how the indys ride, they would give a lower ride height.

Hey i have a buttboard wit indy 215's and a longboard with R-II's. I was wondering if it makes a huge difference between the two trucks. I have been up to about 50mph with the indy's on my buttboard and it doesnt seem to be a huge problem but most people think i should flip the hanger on my R-II and ride with that. Any input would be apreciated. thanks.

In all honesty, the Fork Dog was meant to be different looking above all else. If it functions well, that's a bonus!

As I look over the "Fork Dog", it appears that it is a very functional shape. The "ears" at the front provide maximum length to support your legs, while the little "shoulders" provide a good place to put your hands. I don't know what's up with the tail, though. Is that little flair there to give you more leverage at the back end? Does it still allow your shoulder blades to sit low enough on a tuck?

I took apart my jig because the next board will be different: deep concave in the middle, flattening out towards the ends. This will effectively rocker the board. I'll take a picture of that jig when I make it (after my neighbor repairs his bandsaw).

So, how often have you loaded up the car for a session at the parking garage (HC, Mark Johnson, Mario, Mathew, Miko)…
Gotten busted after 3 or 4 runs…
Hung out skating another hour on just one level until getting busted again…
Try to leave and find your battery dead…
Then have to ask the garage security guy that busted you for a friendly JUMP?
I can confidently say it’s happened to HC at least once…

Oh yeah, on the subject of interesting shapes, Darren had his "Spoon Cat", so I came out with this "Fork Dog".

On the subject of "signature" buttboards, I took my old Chapstik board from the seventies, put it on my scanner, edited the image to make it 48" x 12" and made a template from it.
The result is a Chap-butt board.
