Scale Cat Twenty Two Dozer Ride On For My Son

[ericher69]

Is that seat going to be suspended? Springs or only the inherent cushioning in the foam?

Looks great!

Nope, just 2" of foam.

I originally bought pulleys for flat belts (since I needed them to ride on the backside of the v-belt). They were a little wide and they are crowned in the center. So they didn't quite work how I wanted. So I had to make my own. Out of some scrap of course.








Started on the fuel tank. It's shorter than I want. Oh well. I'll sleep on it before I work on it any further.



And got the handles tack welded.


There really is a lot of crap in a small space.

I've been playing around with sheet metal lately. Way back, I first showed a trial of the fuel/oil tank. It was too straight. I wanted the top to have a little crown to it. Then the second tank I made, it was too short. I can't help it. I'm picky and I want things a certain way.

So this time, I used a digital angle finder and a little gauge. So I'd bend the center to 7 degrees then the outer edges (using the gauge to get the distance from the center even) to 68 degrees. If you notice that doesn't add up, it's because when I put the piece on the table between two clamped pieces of steel spaced 16 inches apart, I get a real nice, and consistent crown. It worked really well.













Here is the fuel/oil tank with one end welded on as well as the front grill surround.



When I laid them on top of each other, they matched up perfectly. I was very happy with they way they turned out this time. And when I mean this time, it wasn't without some failures before I used the angle finder and gauge. Good thing I have a bunch of scrap panels.



However, the next problem I ran into was the hood. I'm using 14 gauge sheet. It was free and nice and heavy duty. The tank was 7 inches wide and the grill is 4 inches wide. It bent fine. The hood....it's 19 inches long. And my bender just wasn't having any of that. I tried a few different things and it just wasn't working. And even if I got the bends, I still probably wouldn't be able to bow it to get that nice crown. I think I'm going to have to try something thinner. I'll go to Menards tomorrow to see if I can find a decent sheet of 18 gauge that I can try out.

As for the sprockets and idler wheels, I'm still waiting on the guy that's going to burn them out. He ordered a hi-def plasma cutter for his shop back in January. It's been delayed a few times but it's supposed to be in by June. I want it to be a nice cut and supposedly hi-def plasma cutters are close to laser. So I'm on hold until then.

Great looking sheet metal work, and your redneck bender did a dam good job.

Where did you get the digital angle gauge?

Show us your shop too. Here is an idea for your tracks made of radial tire with cut off sides.

That is some beautiful work, well done.

Nice. I use EMD Locomotives every day. After seeing your work on this project, I hope they put you in charge of designing the cabs on the new engines.

From my recollection of some 65 years ago 2" of foam only would be pretty scale. I don't recall any springs. Of course my 'forgetter' is rather unreliable these days.

This is a very well designed and built project. I have a struck mini dozer lying in pieces in my garage and the quality does not come close to approaching this

... I have a struck mini dozer lying in pieces in my garage ...

It this a new build or a tear-down?
