I have a couple questions on model bulldozers for you guys…

I’m going to build a couple different bulldozer plans.

The first one is about Norm Marshall’s “Great American Wooden Toy Book” bulldozer…
Any way you can think of to modify this and put working tracks on it? Surely there is. I was thinking of grooving the side pieces and putting a working track on a strap or even put some rollers in it, and do it T&J style. Ideas and suggestions welcome.

The second question is about the T&J bulldozer. Since I didn’t buy the kit with the wheels, I’m planning to turn all of them. Is there any reason those 24 track wheels have to be rounded? I’m thinking they could be beveled instead, which would make turning them easier… not as easy as buying them would be, but still….

this should take care of your first question
now for the second one
them wheels are just guide wheels they could very well be squared off and just eased over
HOPE THIS HELPS :<))

Check out my how to for the excavator which uses the same treads.
I just used some hole sawed blanks for the guides with out any rounding and every thing works fine.
I’ve built and blogged the smaller T&Y dozer.
I used bought wheels for it from Hobby Lobby but you may find some other helpful hints there.
One is how to make the larger guide wheels.
I also built the Wood mags dozer here but gave it a T&J look.

Was going to comment, and put a link to the dozer I built, but GR*HUNTER has beat me to it. The first one I built I turned all the rollers but in the second one I just made a slide, saved allot of time, with the side plate you don’t notice. http://lumberjocks.com/projects/297322 The first one I built http://lumberjocks.com/projects/214930
These dozer where built from pictures. So much easier and fun than plans, plans are often too complicated. Have fun and go for it

Thanks guys. I’ve been perusing those worthwhile threads…

Where do you guys get that black strap?
And can I just epoxy the strap in a butt joint to one of the tracks? OR should I sew it together first?

The first strap I bought from sewing store when I was designing the procedure, the last one I did was just tightening straps from the shelter logic canopy. I can measure what I used It may have been 3/4. just checked. It that webbing’ like ratchet straps.

Another bulldozer question…

I noticed a couple of places in the T&J plan where the end grain “tabs” looked a bit weak.

I also noticed that in HTL’s instructional blog for this bulldozer that he modified the tabs on the cross block to be side grain…
Have any of you built it like the plans show it? Or do you think those end grain tabs are too weak?

I also noticed that HTL cut his body in half and glued it back together. Was there a reason for that?

Underdog for me the plans are just a suggestion of what needs done.
Many time you have to change things up for what tools you have to make it easier and to get it done safely.

Modified tabs
Many times I’ll skip the tabs and add them later because of all the sanding needed to get them to look nice in the corners.
For me this is a model and will not be handled so looks is more important than strength but in many cases how I get it done will in fact make it stronger also.

Cutting the body in half.
I think after two years[??] I was going to have walnut kerf lines and found it would be a pain after I cut it, so went in another direction with it. [just used saw blade kurfs]

I can’t draw a straight line so the plans help me with the shape and dimensions so it looks right when done.
I’ve noticed with some of my scratch builds that the shape can get looking odd if not very careful so the plans help me with that.

Underdog why don’t you start a blog so we can more easily keep up with your *progress and pictures!
