I took a really beautiful truck
and I just hacked the back end of it off here.
Because we have to put our snow track system back here.
Don't email me, don't message me about this,
I feel just as bad as you all are mad at me
for doing this.
But I think it's going to be cool.
Once it has all the stuff in there.
Tracks and awesomeness.
- Max boost (mouths hydraulic sound effects).
- Here is the trailer axle that will be the dummy
axle on the back of the truck.
I chamfered the edges, I lined it up as best I could.
I put some straight edges on it, I tacked it
in three places around the middle.
And then I just butt welded the thing together.
Is that the best way to do it?
No, it should have a sleeve either inside or outside
but I didn't have the material on hand
and I wanted to get this thing together.
And it's really not going to have a lot of weight.
It's mostly just to be the idler-wheel
for our track system on the rear.
But the general idea right now is get this lined up where
we want it and figure out a system to attach it to the end.

- Day five, it's raining here in Spokane, we came for snow.
- Is it really day five?
- I don't know, it's day 'long enough'.
We need to get on the road.
- Alright, hopefully this rain will get really cold
and turn into snow and we can take our snowmobile machine
and go rescue all of Spokane.
We'll be the heroes of the week.
- We're going to Idaho though, so you stay in Spokane,
I'm going snowmobiling in Idaho.
- Let's get this thing on track.
(low-pitched power tool whirring)
(high-pitched power tool whirring)
(chain clanking) The track part of the
snowmobile is the most difficult engineering feat
of this whole project.
Now, you could just go buy tracks,
bolt them on from one of these like
snow track for truck companies.
But that's probably ten or 20 thousand dollars
so we don't have to spend on this.
Our idea is to cut two sets of tire chains down
into one tire chain that wraps around both of them.
Like this, and then have some sort of low buck track system.
Now we just have to figure out if
we can make it all work.
- We're going to make it work.
For the tag axle, for the track system on this truck,
I just welded a set of collars onto the axle tubes
of the 14-bolt little pivot and then this is basically
just a radius arm system that's going to go to that.
This one's not going to articulate different.
It's going to kind of be forced into articulation,
the same as the front axle.
So it'll be using the leaf springs off the front axle
for suspension, sort of.
So I'm going to finish welding this up,
we'll get it tacked to that axle
and see if we can make the tracks fit.

- It's like it's working.
This looks pretty even all the way around.
How'd we do, David?
- We did really well, we did 99% of it really super rad.
We got tires and wheels.
- Done.
- We got our arms on it.
- Yep.
- Shocks are on.
- Done.
- We upgraded steering.
- Yep.
- Super charger, dialed that in.
Run. - Run, skis, are ready to go
on the front, soon as we can find snow.
- Off roady lights?
- Done, and they work, they're wired!
Which is rare for us,
they usually don't-- - Did we get,
did we get red paint on there? - [Fred] Red stripe.
- [David] Red stripe.
- [Fred] Test drive?
- [David] Sure.
- [Fred] Alright Dave. - Let's see what it does.
- [Fred] Let's see what it does.
(chain clanking)
Working over here.
(chain clanking) (slow beat rock guitar music)
I'll stand back and make sure it doesn't take my head off.
- [David] Woohoo!
- [Fred] Alright, so this chain system is working good.
When you go backwards it starts to like walk
underneath the tire and push it off.
But when you forward, it seems to be
right where you want it to be.
- Okay.
Alright I think we got this chain situation figured out.
Fred's over there putting together another set of chains
and then I did a limit strap on here.
Which is just a section of old tire chain as well
to keep this thing from swinging too far.
So, they go nicely with our fancy Fox Shocks.
So we're almost out of here.
- [Fred] Let's go for another test drive
and put it in the trailer, drive out to the snow
and next time you see this truck
it'll be doing rad stuff in the snow
(mouths truck sound effect).
