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.

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...

Wow, you work quick. It looks great. What will you do with your other dozer?

Re: RCLogger
 

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;)

Re: RCLogger
 

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.

Re: RCLogger
 

Joe you can get Clippard without the square ends as well. I have used Clippard for the blade lift cylinders on the D8 build.

Looks good greg ...I may have to come have a look at that bad boy in person this weekend.

Re: RCLogger
 

Greg, The Cat is looking like a piece of "Aluminum Art", How many hours a week are you able to work on this project? Looks like you are ripping rite along. Fred

Re: RCLogger
 

Greg! That Unit is looking Serious!! Ripper makes that Unit!! And looks like it has lot's of depth for ripping.

Re: RCLogger
 

Greg you are doing a very nice job on that dozer looks great keep it up. I like your single tooth ripper better than the multi tooth. Ed

Re: RCLogger
 

I had a chance to mount some pads on the chain todayhttp://i124.photobucket.com/albums/p...02/pads002.jpg

Re: RCLogger
 

Greg Looking better every day. Did you spin that side up. If you put some lead in her, she'll have some serious push for the blade and pull for the ripper
