Weight,length,center of gravity, and gearing seem to be very important in the the construction of these Track sleds. They are very new and nobody has determined the exact dimensions needed for an acceptable operating unit. There are so many variables in building these. Some of the problems people encounter are tippy conditions when turning ( to high of center of gravity), turning in general, and lack of pulling power ( these need to be geared very low and they are not a high speed vehicle 10-15 mph). That being said you can build a decent machine just keep these issues in mind when designing.very interested in seeing how this build goes
I have been looking at the snowdog type build for a while now but haven't got to it yet.
A buddy dropped off a running 243 rotax from an 80's(?) snowmobile some months ago and i thought about trying to set that up. I question the reliability of an old engine while out on the ice a mile from the truck
Most of the track sled styles I see online are in the 200 pound range and for me that is too bulky and heavy but perhaps the weight is needed to keep good traction?
I'll start a thread when i get myself organized but I am also looking to build something like a snowdog that can pull me and my otter cottage sled out on the ice. I am disabled and it is getting far too painful to be pulling my gear by hand.
Those clutches can hold up if you understand how they work. You have to have your gearing right so the clutch slips just enough to get you going. So when your cruising or in the range where you use it the most the clutch is locked up.You might want to consider stepping up to a tav 2. I don’t think that clutch is going to work or hold up very well.
