ya i would be down for this. my dad can probably help some to. i can even sell my DH deck for some funds. i like LDP and Slalom better any way and in the wet season i have no use for it. yeah longboarding is my life so if i can start doing this as a job or even just a side like subsonic or roe i would be so down. i am trying to work on boards to but every one needs trucks to. so JP if your down i am down.

well to be honest I'd be happy to facilitate communication and get you and Spencer working together, and I'd be up for designing, testing the hell out of, and refining the trucks, though I hate riding stuff until it breaks-- done enough of that-- which means we would have to make it as bullet-proof as possible on the first proto!

i'm really hoping Fluitt can share some insight, he's the guy that produced the Splitfire trucks. i know that eventually it took too much of his time and he was contemplating a move to Chinese manufacturing and decided to leave it at that point. if you've watched the truck market over the last decade you'll see it takes a good year or so to go from conception to production -- on anything that lasts in the market anyway.

as i said before if your down i am down. so first before funds and everythign i thing we should atlease have a vague idea about what the plan will be so thats were i will need your help

The first thing of course is research, and tons of that. There's been quite a number of guys taking a crack at precision trucks and DH hangars (and quite a few precision trucks cracking) Wink

Equally important is agreeing on what requirements are essential -- what problems are we solving, what questions are we answering with a new truck design? I noticed someone on a truck thread, mentioning the "hangars must be easily removed", presumably so that the truck is easily adjustable. I'd say although adjustability is convenient, it's not an absolute requirement. After all, PVD hangars were not so easy to remove, yet the trucks were some of the highest regarded in precision/slalom because of their sheer performance. I would much prefer a truck that's a little harder to adjust but never has catastrophic failures, to one that is easy to adjust yet blows out at some point.

Personally, I'd like to see someone strive for simplicity keeping this in mind:

1. distributes load evenly over all stress points
2. uses as few moving parts as possible -- only two parts in total is optimal
3. uses no screw-in parts. optimally, axles should be contiguous and unbroken.
4. baseplates alone solve wedging / dewedging, only flat risers needed, if any.

It would be great if the whole 'double pivot' idea can be solved strictly by shaping and machining a single hangar unit, rather than adding kingpins. The thing I really like about traditional Indys, Bennetts, Trackers and Randals, are that they are simply a baseplate and a hangar.

This first shot's a truck idea apparently conceived by Geezer-X, and Confuscious (from the Fish) was working toward it...

NCDSA herbn's double pivot-pin...

there very first picture really caught my eye. It looks almost like a classic truck with some new age improvements. i have been studying people pumping for a little bit now. and i was thinking of leaning towards more of a airflow or splitfire design. thats why the first truck caught my eye more because it looks like a mixture of them both.

I've wondered a long time whether it would be worth the time and effort (and just how easy/hard) to pre-bend a single, continuous axle, instead of having two separate split axle parts threaded into the hangar. Something like this:

that is a neat idea and if it is not to hard (which i think it would not be that hard) what would the advantage of that? would it be a little stronger? i think i am gunna go with that design because it looks the most promising

Yeah, the most common split-axle design mistake has been not ending the threaded portion soon enough, exposing the threads to stress. Malcolm's GOG broke this way, and I've had it happen on Splitfires as well.

I know straight Randal axles have broken, so the plan is not fool-proof, but I do believe a continuous axle would add strength. Either this, or else embedding the threads even deeper into the hangar, and making the insertion permanent with JB-weld or loc-tite, I know this loc-tite is something people already recommend on these trucks to keep the axles in place, but it still doesn't address the design issue.

i posted this on nwlb to see what they think and they havent said anything yet but lets hope theyd o soon

Do the Virage LDP trucks eliminate the need for this project or is there still room for improvement in high end LDP specific trucks?
