[Grainfarmer]

Hello together!
I want to show you some pictures of my "new" dozer. A good friend made the millied parts in his workshop. Thanks a lot for this wonderful job, Frank!

Nicely done! What tracks & sprockets are you using? They seem familiar but don't recall from where.

[Grainfarmer]

The sprockets and tracks are from http://www.veroma-modellbau.eu/startseite.html
But the track width is a bit smaller as the original. That was done on a milling machine by my buddy...

Looking great Frank!

Nice Job, I am also looking at a conversion of ERTL Dozer, they are all diecast and heavey, perfect for a dozer.

[JAMMER]

Those tracks are plastic but you can get metal ones that look just like those on Ebay that are metal from a place om Canada. Ed

[Grainfarmer]

When the model is finished I´ll see how strong ist is. On the one hand I can add more weight, on the oter hand it would be helpful to fix a 5x5 millimeter L-profile on the tracks to get more grip.

Some more details:
The blade is lifted by a gear rack, the driver used to work on the Foxfire Farm...

Looking great Frank, keep it coming! This Foxfire guys really get around, don't they?

[j_hammer]

what motor did you use. i coveted on couple years ago. i used 90 degree gear boxes but keep striping gears.

[Grainfarmer]

I use RB-motors with a ratio of 75:1. If they are not strong enough I´ll take the 100:1.

Looks amazing! Great job!

[Grainfarmer]

Some steps ahead...
The rear pasrt of the body is fixed by just one screw behind the seat. The front of the hood is fixed by the two bolts. The gap of the bolts is adjusted to the thickness of the front part of the hood, so they are hidden behind the frontgrill...

It works! For the drive motors I use two Servonaust S10 speed controllers. Lifting the blade with a gear rack works very good! Here are the first videos of the test:

The track tensioners will get harder springs, the rest runs very well...

Last week a plumber got robbed here in this region, but I got an alibi...
I guess theight will be about 4,5 - 5kg.

By pushing the muffler, teh main switch is engaged:

Today I changed the springs in the track tensioners by some stronger ones. We´ll see what happens at the next test drive...

[Rvjimd]

Nice work! Is the blade lift motor a dual output shaft 90 degree gear motor turning a gear for each side rack? Thanks for the build thread and pictures!

Jim

[Grainfarmer]

Hello Jim!
A geared motor drives a bevel gear drive that delivers the torque to both sides and drives the rack. It may be seen on a photo some answers erlier.

[rc_farmer]

Frank, another fine job on a conversion. I love this kind of building!

[Grainfarmer]

Thank you. :p
I´m waiting for the decals...hope they are finished soon.

[Grainfarmer]

Two new videos, now with stronger springs in the chain tensioner. Rund much better... :cool:
