I am not sure they are big enough.
There are similar tracks used on farm tractors.
The only problem I have with those is that you have to carry a full track for a spare. A linked track you just need a few feet of it.

I also want a simple, reliable drivetrain that I can carry spare parts easily.
I think I would build with an automotive differential and split braking, then later switch to hydrostatic after I learn more.

I spent three years as a tank mechanic in 29 palms Ca. I don't miss it but I have a book I will give you if you want that covers theorys and designs and how stuff works in a track vehicle application.

That might be a good thing to take a look at. I am interested.

Those pictures look cool. It almost looks like your Wagoneer also. After catching up from the discussion I might have to say steering in both axles would be the easiest. If you had hydraulic steer you could run one pump and have them steer opposite each other all the time.

I will have an IFS suspension (A-arms, spindles, torsionbars) about to free up. Probably be hard to put on the rear of your Jeep but it might be something to ponder.

Nodwells are 4 tracked and steer at both ends, but they move the whole axle, not just the knuckles.

Those pics are cool Dan.

if you wanted to build your own, this style is easiest.


Until someone realizes the Mattracks patent isn't on tracks (look how old those army tracks are, and they aren't Mattracks) and starts giving Mattracks some competition, they are going to be really rare. Someone must have had a warehouse of a few of those military tracks - I searched for years before finding my homebuilt set.
I have the guide for cutting track gears if anyone wanted to copy/modify my track designs.

you know, it's funny to see the military testing tracks AGAIN when they were part of the development the FIRST time.





Edit: I just needed to see the M715 next to the Hummer.

Hmmmm.

lol

The military did not use or design the set I have. They tested them.

Power steering systems and strength have come a long way since then as well.

Mattracks aggresively persues anyone making and selling wheel replacement tracks. I don't know if they bought the rights to some of the older designs or what.

I want to build something with a full track.
Right now I think I have an idea for everything except for the track.
Assuming I don't find a set cheap somewhere, I have to build some.
I can use conveyor belting, but I am having trouble thinking of an easy to fabricate grouser and wheel guide setup.

C-channel would work for the grousers, but for the wheel guides I am at a loss.

Any suggestions?

If I use C-channel with something sticking up inthe middle, and dual rows of boggies, that would work.
I got it...
Now to make a prototype.

Hombuilt Zuk traks - similar to mine, came up with them on his own.
http://www.pirate4x4.com/forum/showt...64#post4847464

another POR thread on tracks - halfway down the Russian version pops up. They cut the sidewalls out of Tires like Boggers and Claws and use the tread as a track - theY center and drive off of plastic buttons bolted in rows down the center of the track.

Cool pics, Where is that blazer at? I thought I saw one similar to it in Ninilchik a few years ago.

The one in the pirate thread that you posted Deepmud.

I wonder where they get those buttons.
Some of those, properly sized, some C-channel, and some belting and I have a start!

I posted in 'em, didn't start those tho' I have started a few




That Blazer is in Maine - the guy who came up with that was selling them like that for about $4k a set - then the evil Mattracks lawyers came to town......


I still don't know if they just bullied the guy, bought him off, or really do have some legal hold on wheel-replacement tracks in the U.S..........


But you can build whatever you want for yourself, even if they did have a patent. You can copy Mattracks bolt for bolt if you don't sell them.

hehe, yep.

from my post on POR


Anyway - he mentioned not being able to read russian - me either, but I did enjoy the Babelfish computer translation
http://www.off-road-drive.ru/index.php?link=160279
so past that link into the "translate page" in this link:
http://babelfish.altavista.com/babelfish/tr
select "from Russian to English" and it makes for a somewhat humorous, but understandable read.
