So what do you guys honestly would grip better, 83a bigzigs or 75a 83mm flywheels?
Whichever one will handle corners better, I will go with... And Ill design the luge around them...
And if I stick with the bigzigs should I go with 8mm truck axles and my favorite bearings, rockets, or should I get 10mm (incase I use bigger wheels in the future or just to be safe) axles and the landyachtz bearings that come with them...."
I would go with Seismics, guaranteed not to explode at 112mph.

In the bay area where is the closest place for a beginer/intermediate rider to go ride a closed (safe) course?
I know of the Bonelli course down south, anything closer or better? I really wanna hit Maryhill one of these days to it looks sick!
Oh and recreational, not racing.

russ, there is a handful of 'pro' street lugers in the bay area,
where are you located, and what is your skill level?

Thanks guys...
Ok so what about if I get some 13ply 3/4" plywood, and do 4" wide booms made of two 3/4" plywood 4" wide strips laminated together?
That would be rock solid and I think somebody on here recommended it... That wont twist to much will it? What would be the best glue to bond them? Where can I get and what type of urethane glue should I get?
Also the seatpan is going to just be 1/4"... I dont want to mess with glass (I do have a lot... and am pretty experienenced)...
Ok a few more things to work out, handle type? What should I look for in handles?
Also, how do I prevent my leg/pants/leathers from hitting the wheels when they are exposed on a rail type luge?
And Russ, I live near San Jose... Their are some luge races in SoCal and I am trying to see whats needed to get a permit for "The Dinosur"... Its a 2.5 mile long hill good for 60-70 on a luge, but the rangers will kick you off without a permit...
Its in Gilroy... Looks awesome...

Jordan, go with footpegs. If you don't want them, hey, cut them off later.
"Angle iron" reinforcement, um, maybe... Aluminum channel in an 'L' will twist, a lot. You'll have to glue it on, and I'd even recommend using small(#8 or 4mm) screws + T-nuts in strategic spots to bind the angle-bits onto the wood. 'C' channel is a good deal stiffer, but again, it can twist easily. The stuff you'd get from a hardware vendor is light-weight, un-heat-treated, basic mush. You'd want better metal, so look at industrial suppliers for ladder manufacturers. By the time you add thick-enough aluminum C channel, glueing, and t-nuts, you might as well put a layer of 3/16" Birch tech-ply + fiberglass to your seatpan. Did I mention that wood + metal don't really 'bond' well? I know I did mention urethane glue before, but now you'll need ski/snowboard flexible epoxy and you'd be in want of a good press/mold too. Glass it, add a layer of marine-quality or tech-ply thin veneer wood, and you'll be alright.
Truck placement: It is a personal choice, as would be bushing or wedge set-up. Leave room fore/aft for changes in overall wheelbase. Start with the front at mid-thigh, the rear just behind your head. 44" to 58" wheelbase is what I've had the best results with, but I've run shorter and longer, depending on sled build; steering required; stability wanted; and truck characteristics. You've got Options with you truck choice, so, don't sweat it until you've run it awhile. I did say to run it awhile?! Yeah, dialin' it in takes some roadwork, and then some re-working, followed by more road time...

Pegged Option

Option D which I am really thinking about now... Its pegged... Its a boom luge... 3/4" 13ply plywood, 4" wide... Makes up the three boom sections... It will have angle iron for reinforcement... Each will bolt to the other threw the angle iron for extra strength... I think I could make a stronger, cooler and better riding pegged luge and for recreational riding it still seems to be up there with the pegless... Plus I will have many years to come to try out pegless and maybe it will be better! But I am thinking about going with my instinct of pegged...

LONGER story

Here is what I posted on the 'fish, its same info but much more detailed... I am leaning towards type A or B, but type C is a good bit simpler and may be more comfortable...
Ok so I have 3 designs now... Help me pick! They also have there own variations... All are "pegless" but some have a full platform, others have a peg for the leg to rest on behind the knee.
What would you recommend?
Design "A"...
http://lugeforce.tripod.com/build/build.html ... Except for a few mods... The booms will be 3/4" plywood instead of 2x4's. The front and back booms will have angle iron attached for strength on the top outside edges, the bottom on the bottom outside edge.... I think this will be just as strong as stacked 3/4"s, if not better. A 3/4" or 1/2" plywood spacer between each will still be used for extra drop, 4 mounting bolts will be used and instead of going threw the wood layers only they will be in the four corners and go threw the top angle iron, threw the 3 layers of wood (front or back top boom, spacer and lower boom) and then the lower angle iron... Should be a really solid attachment and wont need gussets... Then it will simply have a shorter front boom and bike pegs will be just behind my knees for support...
Design "B"...
A 3/4" 13ply seat pan with 4" wide front and back booms made of 3/4" plywood, also with angle iron on top... Will most likely also have a spacer. Very similar to the hybrid luge design that was recently posted in here... And similar to many other rail designs (instead of a boom with a seatpan on top like design A, the seatpan is alone and is connected to the front and back boom, simpler... Not sure if its stronger)...
The front boom will still have the same sort of pegs as design A, only difference is that the seatpan is thick and has no boom underneath it... Bolts to attach the front and back booms will go threw the angle iron, threw the boom, the spacer, the seatpan and then will have large washers on the bottom...
Design "C"
See this link...
http://www.skateluge.com/images/strtlg02.jpg
Its the luge in the back...
Reason I like A and B is I think they will look cooler and possibly be lighter... Design A might be the lightest as the structure for the seatpan is the angle iron reinforced 4" wide 3/4" plywood, and then the seatpan is just 1/4" plywood (verses a full 3/4" plywood seatpan)...
With C I would do the same handles, A and B would be similar (not how luge force did it)...
So any thoughts???
Any of them stronger? Easier for truck mounting? More comfortable? Easier to mount crotch and head rests etc....
Thanks...

Ok so I need to design on whether I am doing a rail type luge but with a peg for my leg to rest on (thats type A)... A flat 3/4" seat pan but with 4" wide rail style front and backs also with a peg for my leg to rest on (type B) or a wide seatpan with wide front and backs... And the front is what my leg rests on... Type C...
Which would you guys go for and why? With the first two I am looking into ways to use just a single 3/4" plywood but to reinforce it with angle iron...
Also I have looked at a bunch of pictures and I cant seem to find a luge with the front truck in the "proper" position!!!
I have heard two guidlines, in between mid thigh and butt and another more specific one, when sitting up and looking inbetween your legs you should be able to see all 4 mounting holes for the trucks but your crotch should almost hide the back two...
Is that right? From pics most front trucks seem to be closer to the knees then to this!!!
Last, does anybody think 3/4" plywood with angle iron attached every 6"s will be any less strong then a double laminate of 3/4" plywood? If I go with a rail type I need to decide for the boom (I dont want 2x4's) if I want double stacked plywood or angle iron reinforced single plywood...
Ill probably spend the money for 13 ply either way... But it will still be only 4"s thick so I may need more structure...

Yeah I think I have the wheel and trucks issues sorted its just the luge design...
I am looking at a few designs...
Either I do a 3/4" plywood seatpan with aluminum rectangular tubing front and back, or 3/4" plywood truck mounts and leg rest...
Another idea is more like the luge force rail design that uses 2x4's, but instead of using 2x4's Ill use two 3/4" plywood 4" wide sheets laminated together...
Not sure if I will have a full leg rest or just some pegs that my legs rest on (like the hybrid metal/wood luge I posted a link to)...

Jordan, better to sort this out here and now than after you've cut up some wood!
Sounds good, should be sweet!
The 4-wheels-to-an-axle setup was from Moe Racing. Last place I saw them on anything other than someone's sled was on Soul Longboard's site.

Geez I keep making this over complicated...
So I think its down to to things now...
Sticking with 4 75a 83mm fly wheels... bear grizzly trucks and 10mm axles.
Either a wood luge with all 3/4" plywood parts or a hybrid like this one...
http://www_silverfishlongboarding_com/forum/showthread.php?t=49643
This thread has a neat luge its pegless, but instead of a full leg support it has pegs which your legs can rest on...
Neat design...
Also I can experiment with a design like this on my idea peg placement, maybe Ill even cut slots so the pegs are adjustable forwards and back? Might be neat...
I just have to make sure I can attach the metal components to the wood well... And do all the other work with the metal (checking on that with my dad...)...

Oh another idea I talked about that might be a good way to go if I am sticking with 4 wheels... What about 85mm speedvents? Big wheels, a bit more like a cross between the flywheel and the bigzig (offset like a bigzig but larger and with a hub like a flywheel)... I beleive they are available in 75a or 79a...
I could do either one (79a would probably be lots of grip, 75a would also) or maybe do a split duro? With standup usually they go more grip in the back because thats what tends to drift but most 6 wheel luges have the extra grip up front so I could do like 75a speedvents in front and 79a in back...?

Sweet I think Ill go with 10mm axles and 83mm 75a flys...
You talk about release... I used to do standup so I know having a good release when entering a drift is important... and even more important is how smooth it regrips! But do people drift luges? How is it done and when is it used... For me as I start Ill probably just be braking enough before corners to take them easily without pushing myself to hard... Seems like cornering is one of the more dangerous aspects of luging anyways and with only 4 wheels I'd hate to push my limit.

Jordan I'd say go with 10mm axles. The downside is ths: Bearing availability. Ceramic or uber-high-tech 608 bearing will be faster, but the axles will bend at some point, you just won't know 'when'. 10mm axles will have a good bit of longer life, especially on rougher roads.
Which stick better? This isn't a 'clean cut' answer, but the question isn't totally fair, kinda falls under "it depends on"... Um, in slalom Zig-Zags are definately better. Flys are Faster, not that Big Zigs are 'slow'. But, Flys have a smoother 'release' when their grip is exceeded, and in 75A (or 78A), the Flys will come pretty close to 83A Zigs in overall grip. Ride quality will be pretty similar, slightly 'plusher' for the Zigs, as the smaller core puts more 'thane between you and the road. Now, go down to 80A Zigs, and the Flys will only have the speed advantage, and the Zigs will have a better grip and ride.

83A Zigs are fine for most roads. If on rougher pavement, go softer, both for grip, and ride comfort. Don't ride sub-80A on HOT (95*F+) days! They'll Goo.
For most riding, the narrow-tail would be fine, but knowing that North + East of you are some amazing hilly roads (that you'll grow into), I'd pick the wider rounded tail. It's better too in tight quarters, as your wheels can't easily get impinged upon by others. The seat pan, I've no comment, something you'll have to figure out as you build.
Urethane glue because, unlike 'white' wood glue, it's very moisture resistant, and unlike epoxy, dosen't need mixing nor is it likely to get brittle over a few years, and a little goes a long ways if you trowel/brush it on.
Yup, bushings come second, after get the ride height/alingment settled. Wedging may not even be needed, but if you do that, you've already got it figured right, just sort out the angles by what rides best.

So I'd be better off with 3/4" seat pan, 3/4" front and back and like 1/2" spacers?
Ill probably do that and just use wheel wells and the bigzigs (75mm zigs)... Will 83a zigs be grippy enough though???
And yeah Ill be sure to test it well, doubt I will test it in stages though Ill probably build the entire thing and then run it nice and easy at first...
Why urethane glue? Epoxy or wood glue not strong enough?
Bushings Ill be playing around with a lot but I am going to stick with the 57/45 degree angling (front and back) most likely... I have played around with wedging on my DH board and cant feel a ton of difference, I think the bushing choices front and back effect the ride a LOT more... I mostly just use less wedge in back so I can use harder bushings without reducing lean.
Thanks guys!

Jordan, the 'stringer' concept is pretty sound, but may make final assembly a bit ugly just in lining up the bolt-thru holes. The sled won't 'perform' well, as you'll have little cornering leverage (no pan), and the sled itself will twist (this is one reason why the slab over the wheels is wide, the other is to keep your legs off the wheels). If you go this route, focus on wheel position, truck alignment, ride height, but don't go on very fast/tech hills, yet. If the sled feels fairly solid and is steerable, tracks straight, then go back, add the pan, and upper over-the-wheel pieces, handholds, seat padding, and check for the need of wheelwells (or not).
You'll notice in the pic of Lott's designs there are two rear set-ups, wide, + narrow. The wide is better for cornering, safer if you've got a ponytail sticking outa the back of yer helmet, and nicer to other racers in close quarters. The skinny tail will let just a hint of deck twist occur, which helps keep the sled in line on bumpier road surfaces (the rear steers just a little less), oh, and you'll soak your collar in the wet with the skinny tail...
After you've got it together, no wheel-rub, no handhold issues, with a comfy pan/seating, run it again, work up to speed in increments. If ANYTHING feels odd/loose/wobbly, stop, inspect the whole sled. Repeat this over three days or so of riding. Take notes (literally) of any probs. After you've 'settled in' and the sled is running o.k., then worry about improving the steering feel with bushings/wedges/wheel options. Your choice of wheels is fine for now (though I was serious about doing shakedown runs on smaller, +- 70mm wheels), Zigs and Flys are great wheels! Be patient enough to not 'just go' and bomb uber-fast (well, not for very long,anyway).
Lastly, once you've got this thing built, use urethane glue (clamp-set to dry) between any plys pieces that won't need to dissassemble for transport. The added glue, plus bolts, will make for a very solid sled.

If you guys think the stringer truck mount idea will work I may just go with the 83mm flys to start! I could even do a 1" stringer (2 1/2" sheets) and 1/4" top... For added strength, wood quality (two different pieces of wood) and more truck lift... Nice thing is the seat pan is always mounted underneath this so it wont make the board any higher... And the leg rest is always just getting higher so the board wont get any lower! (and bottom out)...
Seems like a good idea in theory, any problems I am not seeing with it?
