Got the hydraulic cylinders today: This one has a damaged piston, but i`ll use it to control the vertical motion of both cars. This requires almost no pressure, so it`ll be fine...

Ok, so i started with the first real prototype of the drive sprocket today. This is the drawing: Then i started fabricating it: Unfortunately i`m missing a 20mm drill bit, so i couldn`t finish it. But i just had to tack some tubes on to test if it works. Well, it fit like it was...

Some climbing pics from last year. Also austria...

Finished the shop today: The red markers show the dimensions of the Hägglund: When i`m back from skiing i`ll pick up the donor car and start the project...

Well, i bought the propane kit a while ago, but didn't install it yet, because its just insane cold outside (-21C). Additional i just started the Hägglund project, so there's no time to work on the Ufo...

Put some more work in the shop today:

Worked on the shop today. First i made a welding cart out of a old wood cart. The saw will be bolted on top: There will be tools hanging on the wall: And something to get the welding fumes away:

Because of the fact that the Hägglund will be smaller than a car, i`m able to build it in my other shop. So i started to organizing both shops and getting all my metalworking stuff in my shop. Before: When i called it a day: The old shop: I also cut up all the tires and finished...

Well, i have no idea... But i just talked to a guy that sells me the donor car for about $150...

ETA? What`s that?

We don`t get much snow here at home. That`s why i build it with rubber tracks, so i can use it offroad too... :ylsmoke:

Here the updated sprocket design. I think something like this could actually work... Please note that this is just a try, not the finished design... I also picked up the missing four tires for free:

Well there`s not much progress going on, just more braking parts. The newest thing is that the odometer stopped working... :mad: But i had some free time at work, so i brought it in and changed all fluids and stuff. I also put in a new radiator... And yes, parts are expensive as hell...

This sprocket won't be used because of the reasons you're mentioning. It was just a try. I already had a new idea, that needs some testing... I think the hinge will be fine, but it'll be reinforced with some conveyor belt. The hinges are only a bit smaller than the ones used on the old Kristi...

Started with the first track and sprocket design today. First mock up of the sprocket: Jig for the holes in the track: Tightening the bolts: First part finished: Rear wheel: Sprocket, with updated design: Joint between both parts of the track:

Hi guys, i`m going to add some pictures here from time to time... This was Austria on New Year: And some skiing action:

Ok, my mistake. What`s the right word for the steering setup of a Hägglund? Do you know what ground pressure works well for what type of snow? Anyone has some numbers?

Sorry, my english is just not good enought, ist wasn't my intend to be hostile... There are not many snowmobiles in germany, so it's expensive to get parts for them. If I'd get them for a hundred bucks a piece, I'd buy four and build a set of Mattracks for my L300... Each track has a contact...

Hi, the $800/track is for used ones, don't forget that I'm in Germany. So snowmobile tracks won't happen... The trail this thing is driving on is always groomed, because the hunters use it with ATV's with mattracks on. As for power and traction, don't forget that there's a big surface covered...

Well, snowmobile tracks cost about $800/piece. So it's a bit too much money to spend. I still think i can do the whole thing for less than a grand... Steering will use a normal steering wheel...
