Scale Cat Twenty Two Dozer Ride On For My Son

[Alien]

Holy!! It sure does move along. Sorry about the lawn mum!!!

Great video clip!!! Really impressive seeing it working. Was it comfortable to sit on and operate?

That thing boogies for a dozer. Way cool. Im interested to understand the hydro swivle for the blade? Do you have pics? Ive been wanting to build one of these for quite a while. Ive collected some parts but what really thru me was the swivle for the blade.
Thanks Paul

That is pretty quick. Looks like it's pretty smooth.

I'm going to change the engine pulley. Goes a little too fast. And it's really bumpy on concrete which I expected but real smooth on the grass.

Are you modelling a Cat 22?

Many of them probably had winch operated blades. But, it never hurts to modernize a few things.

Do you have goals for what your kid may end up pushing around? He might get into less trouble with one-way hydraulics, and only hydraulic up on the blade. Perhaps even putting wheels under the ends of the blade so it will do less damage scraping across the lawn.

The Cat 22 is the inspiration but it isn't an exact replica. As for the goals, I have no idea. It's been all over the place. I'll explain a little more below.

Thank you. It isn't too comfortable for me right now but I plan to put some foot pegs up near the engine. That will let my legs stretch out a bit. However, this is for my son mostly so he will fit into it well.

Sorry it's been so long since the last update. Still working on the plow design. Still struggling to make things fit but it's getting better. The hoses have been the hardest part actually.

I'm still not done but here is where I'm at as well as a few stats.

48" wide blade (dozer is 35" wide).
50 degrees of total swivel.
8.5" of blade lift.
Spring loaded for plowing snow in the winter but will lock for the summer.
Hydraulic lift and swivel.

There have been multiple changes but I think this is what I'm going to stick with. I've struggled to figure out what this thing is supposed to be. It started off in my head as a much smaller, lighter, possibly battery powered dozer. Just a toy. It's gone way overboard. Obviously. But it still isn't because I need it. I still don't own any property and if I really did need to do actual work, my brother has more powerful equipment. The only useful work this thing will actually do is plow snow. Other than that, it will be for fun letting my son push around loose piles of dirt at my brothers house and taking it to shows. I've had a lot of fun designing it and building it. If I made it easy, it just wouldn't be any fun.

So here it is.

I have and will continue to see things that I don't like anymore or want to change but there is going to come a point real soon where I'm going to have to live with the design and move forward. I hope to wrap up the design by end of next month.

Thanks for looking.

Well, the good news is, I'm building again. And I bought a new engine. 18.5 hp Briggs with a fuel pump and 9 amp alternator. Need to get files sent out to get parts burned out. The shopping list for fittings, cylinders, hoses, pumps and valves is almost done.

I wish my Dad was as cool as your sons. Nice

Man this project is awesome. I hope I can make time in life busy schedule to make projects like this for my kids. Great job. Can't wait to see it finished.

It's tough some times. I just don't sleep very much. Having a plan drawn up in CAD has helped more than anything else.

In an effort to save some time, I made a visit to the waterjet table.

I finished drilled all the holes though.

Then I started putting some things together.

Been turning a lot of pieces on the lathe as well. I've been making some decent progress just haven't been taking a lot of pictures. After I got it running, I feel that going back to posting pictures of pieces of steel is a little boring.

My brother in law is working on rolling my plow and cutting out a few more pieces. I also need to get moving on my hydraulic parts order.

Also, now that the end is getting somewhat near, I need to start thinking about paint. The real dozers have metal tracks and the whole thing is painted yellow. Being that I have black rubber tracks I wasn't sure how it's going to look.

I've done a couple of different colors schemes. I'm between #2 and #3.

I did a grey one like the Model Twenty I saw at the Caterpillar visitor center. (And a darker grey just for the **** of it). Just to see what it would look like.

Have you considered a military green or dessert camo look? Kids love all things military.

This is a seriously good project. I vote for 2nd combination of colors
