A Panzer IV tank made ??of aluminum and is formed with brush

The second tray gets its stern struts.

Now after the adhesive had cured, I could make the holes for the recording of the roller carriage.

Unlike HL I do not use a screw axis, but the terminal 4mm axles with a small setscrew in the tub.

Then I have done with the cam roller runner blocks further and closed the spring mount in the first step.

Hi Edwin,
I'm very surprised how good your workshop is equipped. But it is still a great challenge, to build your own Panzer IV. I take my hat off to them and wish you much success!

[Edwin]

Now I can start the drive.

For this purpose, I first drilled on the sides of the predrilled holes for the supporting role holder and glued them.

Next, I'm the 16 axes for mounting the roller trolleys from 4mm silver steel. This plan, I turn to one side and solder a washer as a stop biting.

After brazing, I turn the slices on an appropriate measure and verrunde them something. So then they fit perfectly with the cam roller runner.

I have revised the suspension at each side of the drive and joined together to conclude for today. In conjunction with the stable control of the axes of the tub and the softer suspension this works later as they should and not just wobbles a bit with the cam roller runner.

As it stands now, I might next week then with the two wells are completed as far as being able to drive around them.

[Edwin]

After yesterday I was short on tanks Ddernbach today but it was already on.

First I made the drive had finished and also equal the joy of a torn screw. So I have the short hand drilled and cut a M3 thread.

The supporting roles were then mounted quickly.

So then I was first put on the chains and thus define the chain track and measure the width of the chain tensioner.

For the eccentric I found an old piece of brass I can make the holes in the axles and then cut up with a band saw.

In the holes of the axes I file small grooves, so that the solder is sucked clean and a gue connection between shaft and eccentric results.



The axles themselves do I feature 5mm silver steel and cut into one end of an M3 thread. This works best with the aid of a winch on my lathe.

Another little tip for cutting small threads. It works best if you first drill a blind hole and then using a syringe with cutting oil, or as I fill up with coolant-lubricant. When cutting of the threads, the liquid is then displaced upwardly, and the washed fine chips produced during cutting from the hole. These can not jam the tap as fast.



The eccentric, I then brazed to the axles.







And so they are then mounted on the tanks.

[Edwin]

After the eccentric I have finished now I just needed the axles for the idler wheels.
This I have done in the same way as the roller carriage.



And so I had to mount the idlers only.



Next, was the reconstruction and improvement of the gearbox on the other series. A gear do I upgrade to brushless motor on, the second remains conventional.
When two gears I stick the drive axles with gear. So also keeps the permanent and will not solve all the time.



Since the Bruhsless engines have a stronger motor shaft I have to unscrew the pinion. Simply boring work because the cross hole in the pinion gears not only because verläuf the hole and wiggle the pinion.



For the motors I'm still Addapter aluminum and then I had to just screw it. Motors and controllers as I have also the same nioch provided with plugs.





Before I can think of installing the gear but I still need the axle support. I turn first to me once again of an aluminum rod 4 sleeves.



This I have worked so that they fit into the hole at the outer end of the tub and watched a small flanged bearings. So I could then stick to the pan.

[Edwin]

Today I was able to make and glue only the supports of the transmission. That must be hard at first before I can put this.

[Edwin]

So, now was the gearbox fitted to the series.

First there was the tub with the large standard motors turn. Need so that they fit into the bath but all the gear back to the exterior walls and the axes need to be shortened.



the attachment of the gear I can reduce my assembly by way of one, easily accessible screw each gear. So I had to choose only the points for drilling, boring and cut the thread.

But now I had to shorten the shaft clearly as you can see here.





For this, the support bearing is now sitting quite outside.





After fitting the chains as far as the tub is then finished and can be her new owner.







In the second pan with the brushless motor I have the same time also set the gear all the way to the outside and cut the axes.
The flattening of the axes had to be prolonged in all gears, of course. The easiest way is by being careful abfeilt.



Here again the fastening of a transmission with only one screw and then the whole pan with chains





Wed of brushless pan I also made another test drive because the controller settings.

The suspension works in the context of the possible suspension travel now quite well. Your owner will first have to stick together all the roles well. I did the same at the beginning of the test drive lost half of the rollers.

But this tub is not yet clear. In it, I will test new engines with flywheels and if they are good to their owners must also equal delighted ...

[lliw180]

what are thoes speed controlers ? also you should get a job with nasa building robots thay send to other planets

[trackmech81]

Beautiful work of art.

[Edwin]

As I wrote yesterday, I still got the new brushless motors are also suitable for mounting rotating masses on this gear and then today I have tested and installed.

First I cut off but two steel washers for flywheels with the band saw and the engines to be installed in the transmission rebuilt.





The steel discs, I then put on the lathe to shape and drilled the mounts.





And so then I was able to install everything in the gearbox. Further adjustments were not necessary to pan and transmission.



After I had finished the drive an extensive test drive was of course necessary and I am satisfied.

Now both tanks can be sent to your owners and maybe then dip it in a building report so again.
