i........... can't.............stop!!!!!!!!!!!!!!!!!!
I love this $hit! to top it off I looked into going back to btc for more welding, fabrication, cad and machining classes today.

Do you think that there would be a balance issue with the diamond drive containing everthing on one side? Maybe throw a brick or something else high tech on the other side to balance 'er out? hahaha

Another approach for the front end
Gary, I really like your idea of using the parralel link suspension for the front end of the concept machine. I even drew a few sketches and I think we could probably pull it off pretty good.
But by whipping things around and doing some sketches, I had another Idea that comes with a major strike but I think the concept would be damn great. Here is it : I'd use a Cannondale Lefty style of fork. (http://www.cannondale.com/suspension/09/index.html). That idea means we would have to design & fabricate a fork that has the same features as the lefty : besides holding a bicycle wheel from only one side, the major particularity of a lefty fork is that the lower fork tube doesn't spin in the upper fork tube unlike all the other forks legs.
If we could come up with a fork like that (it would probably end up looking like a 5" log !!!), and turn bearing shoulders into the top & bottom of the outer upper tube so that it's held by these bearings who'd be held by the frame. The center of the fork would be the pivot of course and we would have a clamp-on bracket somewhere on it to screw on the steering rod like the one we got on our steering post.
Thye bottom would reproduce the Hawk ski adaptor with a similar trail measurment.
One component, the Fork, would handle the steering & front suspension, one hole in the belly pan, simpler frame, less moving parts, more area to wrap the pipe around... Probably not a bad solution considering the weight... And how plush would a 5" fork be !!! ... but how freaking difficult (& expensive) the single fork would be to design/fabricate... There's not that many people making that type of parts... We may be able to have most of these parts made by a subcontractant... We could have Procircuit or factory connection to Titanium coat the lower fork leg !
I'll post a drawing of my idea in the next few days...
I think if I had to make a prototype that "i" could sell to the big 4, that's what I'd go for...

awesome!
great idea but the cost to research and develope a "log" other than natures own logs would probly cost more then adb spent on the whole entire hawk! i like th idea of the single hole belly, and the ease of pipe fitment...you have a lefty fork apart?

Not that bad to build a "lefty style" log fork actually !
What prevents the lefty lower tube from spinning inside the upper tube is just 4 flats on the lower section (like wrench flats on a rod). These 4 flats runs on needle bearings at the base of the upper fork tube and then pevents the 2 parts from spinning into each other. You also get rid of all friction from "bushings" rubbing against each other throughout the stroke. The thing though is we would probably need something like 16 inches of flats if we wanted 12 inches of stroke out of her. That would make a pretty damn long fork I think...
The upper section of the lower tube is circular & conventionnal fork mechanic is in there. So it wouldn't be thaaaaaaat bad to build. Getting it to work right might be a pain though... What scares me the most with fork parts are tolerances that these things are built off of...
I wish I had one to take apart... I've been looking for one for my XC bike frame that I build 2 years ago... Still no parts on it... Snow-Hawking is too expensive...

Super tec.!!!!!!!!
i THINK i MIGHT HAVE SOME SPACE SHUTTLE PARTS LYING AROUND YOU COULD TRY AND FIT IN THERE TOO!!!!!!!! super cool concept, wonder if anything exists that could be tweaked to fit your idea?

Great "Lefty" idea! I love thinking outside the Box. I'll do some thinking about your ideas and get back with you; but you're onto something. What's important is travel and weight, which can be attacked.
-On a separate note; I've decided after talking with Scram600 to purchase a 480 Fan Phazer (you can find them all day long for $500) and Use as many parts as possible, and morph it into a Hawk as cheaply and easily as possible. I will use the Engine, Pipe, Clutch's, Brakes, Handlebar, Gauges, etc. Not sure about rear suspension? I want to use 136" track 2 1/4" paddles, converted to 12" wide, but the Phazers lack a good track. The perfect donor machine would have the rear suspension and track to begin with.
Any Ideas?
Remember cheap is the Key.
-I have a "Main Goal" of 300 lbs Dry for the machine. I hope your Lefty or my Duo link idea will work on it!
-We can do it, and I like your Lefty idea alot........
-"a twist of the wrist - all my demons fall behind - buried in the wind "

Front Fork
What about using one fork with a large tube diameter and letting it rotate inside. It would be like using one of yamaha's tss struts but on a larger scale, I guess you'd have to use a knuckle like they have to link the steering to the telescopic tube. For the rear suspension, could the coil springs and uppr idlers be eliminated and torsion springs used instead, maybe a shock setup like a scotts steering damper too? This is what you've got me thinking about at night now

Might / Should work
Why not, that might / should work.....more things to consider...

Cheap can aso be a lifestye, untill the bailing twine used for rappeling gives way, fall in style would ya?
Better.

nice drawing...btu where does the motor go? i dont want my scarf getting sucked into the carb like the old 1 lungers!
as far as motors go....find complete running sleds! i bought a 1995 formula sl500 with the rotax 503 for my hawk and a whole front end to fix my sled that got hit by a car. sold most of the other parts(seat rear suspension etc) i got it for 690 then with selling the other stuff...very cheap way to accumulate parts!
any idea on the phazer 480 Horsepower? maybe thats whats in the 503 sitting on top of the mt in the abandoned snohawk posts....they say its got a yami motor in it!!

Wow a Rotax Air Cooled 775....that would be great but parts would be a problem.
Not sure yet what the HP is on the 480, but they run strong and have been making them from 84-97 so parts availability should be good. anyone know where you can find snowmobile facts? I've also been told the Yami 540 Fan is good as well.
The picture on the Left is just a concept from BMW which is there for ideas only, you're right where would the engine go? The first picture is the Lefty.
-The Ski-Doo Formula SL 500 was my first pick, i'm glad you brought it up. It has everything including the rear suspension one can build on. I didn't bring it up before as not to slant what others might bring up. You're right, it's a good choice.......
Tony says the Newer Arctic Cat's with Diamond Drive, Injected and the Expansion camber over the heads is the Ideal way too go........He's right also if you can aford the Donar to begin with.........

Hawk Rear Suspension Travel?
Does anyone know off hand that the Hawk's (say 600/800) Rear suspension Travel is? the Front is 12"................................

1990 phazer - 63 hp @ 6800 rpm, SX piston mod = +4hp, if you can get an aaen pipe and make it fit without modifying the dimensions you can get up to 84 hp @ 7500 rpm. An old rotary valved 583 rotax w/minimal work can run 105 hp - worth the extra weight of the coolant I'd say. Now add a turbo to that 583 with 8 1/2 lbs boost and get around 155 hp!! The old 775 rotax is fan cooled, puts out around 60 hp, is terrible to pull over and definitly hard to get parts for.
