Default snowmobile trailer build

No not that kind of trailer, the other kind.. this is a project that I have wanted to do for literally 25 years. In fact, I have been storing these old skis and snowboards for at least that long, for this purpose... ask anyone who has helped me move. The dream has always been to one day own a snowmobile, build a trailer, then head up with a few other folks and take turns shuttling each other up and down some sweet powder bowl, build a kicker, make lunch, etc. We'll see if I can pull that off.

Anyway the first major milestones are complete. I started by essentially building a bed frame. Had some 2" angle here, so went to town on gobbling that up. Few other steel pieces, mostly surplus from roof rack creations, in fact I did this whole project without having to buy a new piece of steel. Not really sure what I'm doing, but figured I'd have the skis sorta follow the tracks from the snowmobile skis, and the snowboards 1.5" higher which will ride where the track was. In my head, this keeps the trailer more or less in line, but the skinny skis won't sink if there's powder, as all the weight gets supported by the snowboards. Here's how that all looked when zapped up and bolted together... I know, kinda Red Green inspired.

I then made a "tongue" I guess.. something to connect the trailer to the sled, and allow for some length adjustability and also up and down action. Pretty simple technology of 3/4" squares sliding into 1" squares, something I'm pretty used to... and I already had the hitch pins. here's what that ended up looking like, also now with the skis mounted..

I had a little more fun on the snowmobile side. Made a frame that bolts to the sled, again allows for more up and down action. It also can lock out in an "up" position using another set of hitch pins, and I made limiters out of some leftover chain from a shop light. Bolted a 1" receiver hitch to the center...

Then came the really fun part, figuring out how to connect it all. Inspired by my "lock-n-roll" hitch on the camper, I used some gussets and a scrap of angle to fabricate a couple angle pieces, which when bolted together will allow for about every twisty movement I could think of. So all combined I've got two separate up/down points, one at the sled the other at the trailer, and this twisty coupler that would allow the trailer to do a full flip... a la Old 40 Dog in the Swell style. Never done this before, but in my head this makes sense, and it's better than just using a rope at least the trailer won't run into the track when I go down a hill, right?

I realized that if I stand on top of the snowboards, they are unsupported and I could likely rip my bolts out. So I ran down the hill and bought a 2x4 sheet of pressure treated plywood. that wood almost doubled the weight of this thing (went from about 50 to closer to 85, guessing) but it's more practical. Now I can put whatever I want up there.

Still to do is to find or build some snowboard holders, then either weld or bolt those to the side of the tray. The idea is I'll just fill a plastic tote full of lunch gear, strap it down to the tray, then someone can sit on that... with 2 others on the snowmobile. I just need to wait a few more months now to see if this actually works, and how much of a hill I can actually climb when loaded down, etc. Even if it's not perfect, was still fun to make!
