after a very busy period, I found some time again to continue the project. I have made some modifications to the baseplate of the body and the connection plate for the boom to receive the CTI slip ring.

today I put together the sprocket wheel.
I used the following items in addition to the alu cut wheels:
- piece of M2 threaded rod
- M2,5 bolt 8mm long
- M6 to 4mm part to connect the sprocket wheel to the motor
- M2 nut
![](http://i1243.photobucket.com/albums/gg543/kovadest/ALU%20parts/day14/B204A223-8BDA-46AD-876B-08FED845F1B9-8659-00000884D28A97BF.jpg)
detail of the connection piece

with a 6mm drill bit I started to make the holes bigger

then i used a 5,5mm drill bit to make the other holes bigger. I used a M6 steel bolt to thread the 5,5mm holes of the round plates so they would fit on the connection piece
![](http://i1243.photobucket.com/albums/gg543/kovadest/ALU%20parts/day14/565A7B28-60BC-4562-BC15-5E433D25B620-8659-00000884FFBF5E9F.jpg)

then i drilled a 2mm hole in the middle of the connection piece so I could fit the M2,5 bolt in it to hold the last 3 round plates
![](http://i1243.photobucket.com/albums/gg543/kovadest/ALU%20parts/day14/DDC3742A-30CC-47D9-B8B7-F4471B6FDAE1-8659-00000885030AF40D.jpg)

thats how the front looks

the back side, after cutting of the excess of the M2 rod and adding the nut.

i decided to add 16 bolts M2 of 6mm to finish off the front

putting together the bottom rollers for the chain (5 rollers on each side). Therefore I am using a 3mm copper tube with inner diameter 2mm. When I fit a 2mm threaded rod with two nuts, its holding the sides of the undercarriage very well. Tomorrow, when time permits, I'll do the top rollers.
So, except for the buckets, there is no brazing or welding required on the model

Currently using the bruder plastic tracks just as a test while waiting for the delivery of the final tracks.

All brazing done with Easyweld de Durafix. It worked really well and the result is nice.
I am using a normal torch to heat up the aluminum.
1. Very important is to clean the place which you want to de brazing on with the copper brush
2. heat up the aluminum till its hot (i mean really HOT)
3. only then come carefully in with the aluminum flux rods from easyweld. if you come in too early, they will melt and bulb up with an ugly result.
4. slightly rub with the flux rods on the hot aluminum and you will see it melts nice and evenly while you pull the rods over the hot surface.
