Another Mini-Dozer

[grsthegreat]

Now this is too cool for school! I'm looking forward to seeing more pix as this progresses.

Is 16HP going to be enough ponies?

If anyone needed access to a CNC laser or water cutting system, it's you. Did you look into having the parts cut that way?

My plasma cutter cnc unit couldnt have maqe sprockets as nice as those. Plasma has trouble with cutting circles.....thay tell me its due to the swirling action of the air. The edges of mine are a bit sloped.

First your work looks very good, and your tracks look very good,

but I have a question, has any one ever cut the side wall down on a tractor tire and stretched it over two air filled tires to use as a tracks? and if so how did it work?

These guys sell a little unit with just that for tracks. In fact, it seems like their main business is tire recycling. I don't know how well that system would hold up in a dozer situation.

ATV, Mini Track Vehicle, tracked mini. ATV. tread truck. atv new. atv off road.

Edit: Apparently they aren't selling many. I just saw that the video and the blog are both out of date. The video had a kid riding pretty aggressivly and the tracks seemed to be holding just fine.

You are an artist! That being said and believe me I'm no expert but do you think the tracks will hold up to the torsional forces? I guess what I mean is the fact that they are only riding on the center 3/4" sprocket. In my thinking if you run over a small rock and tilt the inside or outside a lot will the track still remain true?
Great job so far.

Man that is very impressive! I'm tagging along for this one! Do you anticipate any wear issues with the sprockets not being hardened steel?
Very nice work so far! Btw, what kind of welding machine are you using?

I really havn't given it that much thought. Its going to have three bogey wheels per side but they are riding on the center of the track too.I guess I could have a problem with that. I noticed that the old Struck units didn't have any bogey wheels at all and the track shoes were made from 10 gauge material. I wonder how well they performed. The new models have double sprockets on them as well as bogies so I'm guessing it must have been somewhat of a problem.:confused3:

I think the bogey wheels should stradle the drive link part of the chain. This could be done with 6 wheels per side or 3 wheels with a groove cut in them. It may throw a track if you go over a rock or something...

Answer: I'm not too worried about it. I figure the track will be the big problem for wear though I have case hardened the areas on the track feet that surround the pin holes.

Very nice work so far! Btw, what kind of welding machine are you using?

Answer: It's my old Lincoln 225 amp AC stick welder that I received as a graduation present in the year 1974 !

The "MD" line which Struck sold back in the 60's/70's (and whos transmission I am copying) was offered with ones choice of 3 engines: 7, 12, or 16 HP.

I didn't consider those cutting systems because I figured it would be out of my price range.

I love it!
