He is at it again! 1:50 Dozer Conversion

[Rvjimd]

I just got it going and expect I'll have some adjustments to make before long. I also don't have the blade hooked up yet and I should be able to get that working as well.

The tracks are going to be trouble. Ther roll really nice and free, but anything in the links causes trouble. I have a few ideas, but I'm going to finish the blade control first. It may become more of a clean surface machine if I have too much trouble with the tracks. The biggest problem is the scale. Seems like small grains of sand not only get into the links and clog up when the sprocket comes around, but the treads also bind up. I may try to clean out some of the paint where it is real tight, but that is on the back burner for now.

I'll get some photos of the details of the drive system in a day or so...

Jim, your 1/16 conversion runs nice. Nice job.

On my cable excavator i had to "sharpen" the cups between each tooth so that basically just about a knife blades width actually touches the tracks so that dirt doesn't bind it up.

Scott,

Ya, I remember you telling me that about the cog wheels, I'm probably going to try that at some point.

Rcp, the machine is made by SpecCast. Is is labeled as 1/16 scale, Oliver OC-12 crawler with blade. They make a version without the blade for about $5 less. That one comes with an umbrella.

Here is a picture of the SECOND one I just bought today along with a few build pictures I took.

Scott,

Do you have a pic of the knife edge on the cog wheels? When I read the last post, I made me pause. I would have shaved off the points? Now I'm confused...

Got the blade control working. I'm happy with the overall function of blade and tracks. I need to see if I can find some metal crown gears to use in place of the plastic slot.it crowns, they are not going to take the abuse.

And I need an operator! Are there 1:16 scale figures that would work for me as an operator? Would I find something like that at walmart or a toy store?

It runs great Jim, good job.

Bruder people are 1/16 and look ok.

i tried to take pictures of the drive sprocket teeth last night and it just doesn't show how i modified them.

Give me a call today and i'll try to explain it better on the phone.
