Well that cant be much more of a challenge then drilling all those holes !

Singles have that off road heavy duty tear'em up go anywhere look. That will really make this one jump out.

Excellent work , thanks for the detailed progression pics. B)

Thank you Sean. Gator brought up the single grouser shoe and it will definitely look better than the Bruder track shoes

I completed modifying one set of tracks from triple to single grouser.

The first order of business was to remove the existing grouser bars.

This was accomplished with the help of a belt sander:

After removing as much stock as possible with the sander, I finished with 80 grit by hand. This picture shows the bars removed:

In this picture on the left is a piece of .015” styrene cut to 5/16” X 1-9/16”. this was glued to the top of each shoe to cover any imperfections that sanding did not remove.

On the right is what was used for the single grouser bar. It’s .060” X .100” styrene (Evergreen # 155):

Here’s the completed track:

There’s a lot left to accomplish on this build. I’m waiting on parts to modify the drive sprockets. Once they arrive and are installed, the front and rear idlers will be scratch built along with the track rollers.

So for now, panel lines have to be scribed for the hood side panels and modifications to the blade are needed.

Dennis,

Your work on the tracks was wlorht it. They look very good!

What other electric tools do you have? Besides the sander and drill press?

I have the budget minded 2" tablesaw from Micro Mark, And it has more than paid for itself over the years. i would like a belt sander and drill press and the bigger better 2' table saw.

Be Well

Gator

Those are awesome, they look way better then those highway pads.

So my big question is - How many are there ? :lol:

I cant wait to see what you do for the rollers and drive sprockets .

Too many! :lol: I counted 53 Sean. The other track still needs to be completed. Purchasing the belt sander for this was money well spent.

The only other power tool is a band saw I've had for quite a few years. The drill press is a handy and versatile tool.

Beautiful Work!

Great progress... B)

Thank you Ira!

Love the work you doing to this TOY :P It should be fantastic once completed ;) Are you going to R/C it? or is it going to be a load

Thanks Dave...it will be a load for a 125 ton trailer that I plan to start on soon.

I have seen builds that have been converted to R/C....I applaud them for their work!

The existing drive sprockets were modified for a more realistic look. These pictures show the saw cuts that were made:

The following pictures show the modifications made. In the first picture, 1” CPVC was inserted and 1/4” was left exposed. The exposed part was wrapped with .040’ styrene

 

for height correction:

I forgot to take a picture of the gear before installing…DUH!
