Awesome Greg! I must have missed this thread, because this is the first I've seen of it! Really looking forward to seeing the progress on this dozer. I was thinking about trying my hand at building something with tracks. Anything with tracks, but I don't have a clue where to start. Been looking at roller chain and K-1 adapters for pad mounts. I think you have answered most of my questions there. I'm curious though, what you might suggest for idler wheels and bearings, if not bushings? Do you make all your own parts? What sort of tools and equipment do you have? I'm guessing you've got a lathe and mill somewhere in your shop. I really need my own mill! It would really help me on any project I tackle.

The roller chain K1 that I use is not flat on the inside, it is like bike chain. So I cheat and use teflon instead of rollers. It works well, very smooth and no drag, chain never plugs up. I do make alot easy to do parts, I use a small lathe and a small mill..http://www.busybeetools.com/products...ADOUT-MT3.html
I seem to build equipment strong enough as I don't ever have break downs. but if something does break it is nice that I don't have to wait for parts like some folks are having..;)

HAPPY NEW YEAR !
Looks like everyone is getting some modeling in over the holidays. So I thought I would add my progress as well.

Was at Greg's this afternoon for a preview. Seeing this model up close is amazing. This model is going to be a power house and a great runner. He's really mastered the art of fabricating models.

Re: RCLogger

Greg that is a very nice job you are doing on the dozer it looks real good. I like the high track that is what I want to do to the Stahl dozer I got if I ever get all the pieces from Germany to finish it. keep up the good work. Ed;):)

Re: RCLogger

Thanks Fred and Ed
I must say that the high track works very well. Mine has never plugged up with dirt as the sprocket is high and dry.. Usually by the time the chain makes its way to the sprocket most of the dirt has fallen off..

Sure looks like you could drag that through a lot of rock. How;d the bees wax work. Maybe you still need less teeth on the blade.

You used a scroll saw to cut that tooth out Greg?

And it looks like your tip is replaceable too? :D

Re: RCLogger

Great progress, Greg! I might have missed this, but what do you scale your models off of? A die-cast replica, or actual drawings? Maybe manuals with dimensions, or a combination of things? Do you have a spring tensioner for the track? One thing that I was really wondering about, and something I have never had the chance to check out on a 1:1 dozer is the tracks can walk or articulate up and down, right? There is usually a bar that oscillates in the undercarriage. With the high drive tracks, and the drive sprocket being fixed in location, if a track articulates up, the track would get looser? So some sort of automatic track tensioning system must be necessary?

Joe I used the band saw to cut it out, just takes a little more time and patience than I have.:) The tip is replaceable, I milled out the back and used the split pins to hold it in place.

Re: RCLogger

Thanks for the kind words guys !

I guess you could say its a little brother, but Dan it is from another family compared to your machine. Mine is stand a few hundred feet away scale compared to yours.LOL

Nathan I use photo's from the internet and I scale up brochers. As far as the track tension, I do use a spring in the track frames to keep the tension, also if a rock or any type of debree goes into the idelers the spring compensates. If you look at the 1-1 the pivot point is just ahead of the sprocket on the track frame. They have a system to keep the proper track tension as well...

Great progress Greg! Love that you made the tooth on the ripper removable, then when it wears down from ripping rock you can change it out;)

A little more work done on the ripper. Still have some more work to get it finished up.

You're not kidding. Make it an even dozen. :D

I think you mentioned using air cylinders from McMaster for this and other projects...they hold up pretty good? I think I like the looks of those better than Clippards. Keep thinking I need to do something to turn down the square ends on the Clippards.
