My Weekend project: Trike ski * NEW VIDEO ADDED*

[Scootertrash]

I have so many potential projects in my head I don't have room for anything else. I've pondered a track system like the yeti set up, just haven't gotten around to it. I have a couple of extra sled tunnels here and I haven't really looked at it hard, but I was thinkin maybe I could mod a sled tunnel to add a track system. Still lots of finangleing to do to get a plan started.

The steering is very responsive, at times almost too responsive. I think once the carbide on the wear rod wears in it will mellow out a bit. The sled trails are definitely better with a fresh coating of snow.

4-Snows came today, got em in the basement warming up before I mount them (on the rims )

Got a little better video the other day with the 4_snows and the new ski:

Looks really good! Congrats on a kick ass setup

I built a ski last year and had the same issue with darting and the steering being too responsive. The remedy was to chop up the scag and move the carbide back. I moved it back so that about 60% of the carbide was behind the axle. much better handling after that. If you search "tecate ski" the one I made will come right up.

I don't think the responsiveness of the steering is anything that wouldn't be expected with 6 inches of brand new carbide, and darting is going to be a factor on old snowmobile trail whenever you hit an old ski path. If there is darting in fresh snow with no old ski path to snag, there are other issues somewhere that need to be addressed.

I couldn't cut and relocate the skag on this ski. As it is designed, the carbide is centered under the mount bolt for the ski, which is the "axle" for the ski, so 50% of the main carbide is behind the axle already. There is a small piece of carbide towards the front of the ski, but this only comes into play on a limited basis for icy snowbanks and the like.
The ski I used also has a 7/8 inch keel on it and the skag is nested in the keel. The keel works extremely well in soft snow/powder type conditions.

Here is a pic of the camoplast ski next to the old Polaris ski I used for the initial design. Big difference in the keel design between the 2 skis.:



I got one of the first ski kit frames painted up and got the plugs for the open ends.





This week I going to try to get designs figured out for the 200X, 250R, 350X, and 250ES. I've got forks for the first 3, need to get my neighbors 250ES over here to get measurements for that one.

Well winter is back again.... is there a new thread started? What's the deal on the ski kit?

[Scootertrash]

Picked up some steel last week, first project is for a 250 Big Red for a member here. Just got the BR to my house last night for fitting and test mounting.

After that I'm going to try to get started on the 200X, 250R, and 350X versions. Just have to juggle "responsible time" with "play time" *sigh* :I (busy at work.....)

Maybe I'll start a thread in the New Product Forum when I get rolling.

I have to say that your design is perfect. If you want to sell some kit i know an atc 200 that would be happy!
