4 Hour Bruder Dozer

After playing with my 955 I thought I would see how a plastic toy would do. It did OK at first but once the tracks and drive wheels got dirty they started to slip. I may have to build some tracks for this down the road...and then probably a blade and a....lol

.....I've been telling myself not to do this for over a year and a half but I figure WTF! So here we go....

I've never tried making sprockets before....

Hahaha, your the only person that I didn't want to see this Jason. I guess I should have cut another set of sprockets hey? I hope this works but we'll have to wait and see.

Well, this thread should not be called "4 Hour Bruder Dozer" anymore. I spent at least 5 hours working on it just today alone!lol

I finished up the sprockets and made new idlers for the front and rear. I'm cheap so the plan is to TIG weld nuts to the chain again like I did on my 955K and EC300. I wish I could just use K1 links but it's not in the budget. Right now it is still running the 360 servos that I put in it to begin with. They are only 50-60oz/in so they need to be upgraded. In the video it is only running off of 4, AA batteries. After filming the video, I wired in a BEC switched to 6v and ran everything off of a 7.2v battery. It was a definite improvement but still not enough for metal tracks. I made the hubs so that they can be drilled out to fit on gear motors should I ditch the servo idea. I may just go that route instead of using high torque servos but I will have to see what fits best in the model and my budget.

Here's how things are turning out so far. Kinda like putting lipstick on a pig I suppose....

After finishing up my work day in the shop I spent a couple of hours tonight working on my dozer again. I have to pick up some things before I can make any more progress on the tracks so I decided to get started on the blade. I made it slightly wider than the plastic blade and angled out the corner bits. I am looking at this project as practice for my next scratch build so hopefully I can learn a thing or two along the way.
