Tucker Sno Cat
 

Ok, what I have is a scale drawing in 1/10th (also in 1/16th scale) scale of a Tucker Sno Cat that is a 4 tracked motivated off road vehicle.
This will be a slow build due to everything on it will have to be scratch built because of its oddity.
I does require a pair of axle housings and a transfer case of some style but that is about all as far as a regular crawler.
The steering and the track mounting points will be a project in them selves.
Anyhow,,,,, some pics to start with.

AWESOME! Is it done yet? :mrgreen:

How about now?

OK I'm really anxious to see the completed project!

re: Tucker Sno Cat
 

Hmm,,,, me too :mrgreen:.

re: Tucker Sno Cat
 

So,,,, it begins :shock:
2 complete sets (4 track sets) of Heng Long German Tiger 1 track sets.

re: Tucker Sno Cat
 

Love the plan, however its been done and done well if you ask me. Not discouraging you, but I though you might get some inspiration. Looks like you planning on a super scale replica...

I saw this thread last year and thought it was cool.

Yea I've seen that one a couple places.
I plan a different setup as far as for steering as I won't be using Cs and knuckles.
My plan, as the original is is to rotate each pair of tracks on a large (2 1/2" O.D.) Torrington thrust bearings on turntables under the chassis.
And the fabricated tracks will resemble the originals also.

So I'm gonna need a pair of SSD D60's for housings.
Not sure of width yet so don't know which version I'll need yet.
And the original is leaf sprung :ror:, that sounds like it will be fun because I think I'm looking at some serious weight here.

Have you seen the ssd pro44 axles?

Yes I have "thumbsup", I've got a bunch of measuring and mocking up to do before I can decide on which housings to use.
I'm thinking about the SSD scale trans/transfer case unit also.

re: Tucker Sno Cat
 

I think he should use that as inspiration and as a reason to proceed with this build rather than saying "It's been done" and giving up. This is a great build, but there is room for improvement. "thumbsup"

re: Tucker Sno Cat
 

Yea, I'm not saying I can do it better. I'm just going to do it my way, albeit the harder way.
Body, leaf spring suspension and turntable steering will all be projects in themselves individually.

re: Tucker Sno Cat
 

Ok, it begins. :twisted:
I've got all 4 corner track motion systems coming along with 2 /1"2" O.D. thrust bearings and 20 sheets of styrene.
And I have a ton of delrin to mill chassis parts from.

re: Tucker Sno Cat
 

And for motivation and steering duties, the traditional crawler stuff 8).

re: Tucker Sno Cat
 

Leaf springs,,,,,,,,, hmm.
If ya notice in the drawings above of the turntable (it wont be plywood but delrin) and the track profile you'll notice the 4 ears on the turntable, these are the mounting locations of the spring hangers.
And if you look right at the very top of the track you'll see the leaf spring in its location.
Since this rig will be a fatty, what ya guys think would work for the leaves?
Has anyone ever used the spring from a pull start lawnmower?

Hmmm, , with higher proportion to the rear,, from what I can read about the steering it favors the rear just like a snowmobile would. Real one uses a single hydrsulic ram to steer both pairs of tracks .Interesting, very interesting.:ror:
And the suspension platforms are only attached a single pivot in the center with clamps that keep it rotating on center with very little side to side movnent. :shock:
Hmmm,,

re: Tucker Sno Cat
 

I've had good results with heavy duty radiator clamps. Lawn mower recoil springs seem kind of flimsy.https://uploads.tapatalk-cdn.com/201...6252783e1d.jpg

What are you using to narrow them?
Shears?

re: Tucker Sno Cat
 

I used a fiber cut off wheel on a Dremel. I've also cut them on a band saw. Never tried shears or tin snips. Should work though.
