Winter project

Post by Adrian Harris » Tue Oct 08, 2013 11:12 pm

Once again the Armortek Open Day resulted in more metal following me home...
DSC_0574-reduced.jpg
This is Panzer III number 018, from the first production run.

It's currently a runner, though a quick check on the bench tonight found that one of the motors is loose, several of the wheels are extremely stiff and most of the axles move on the torsion bars, so plenty to be getting on with :lol: :lol:

I hope to be able to modify and add to this model without a complete strip down, so I can keep it as a runner for as long as possible.

I've always liked the Panzer III shape and at least with a model this size I can lift the lower hull on and off the bench without assistance, once I've removed the batteries...

You probably could have :lol: :lol:

I've stripped off the wheels and removed the bearings, to try and see why the wheels were so stiff. There's some blue gunk in the wheel, which looks like it ought to be thread lock, but they all came out with just finger pressure, so I don't know what it is. It has a dry jelly like consistency

I can tell from what's left in the wheels that the bearings hadn't been seated fully against the bottom of the wheel recess, which is why they were stiff when the end caps were tightened.

I notice from the Stug III instructions that Mark now recommends slackening off the end cap by a quarter turn before the thread lock has solidified, which would prevent this stiff wheel syndrome.

Quite a while ago now but if I remember correctly I had to insert some thin washers between end caps and shafts on some of the top idlers. I think this is the PZ111 that I modified the 6 channel radio on to get the sound working, am I right Adrian ?

The Futaba transmitter certainly has a six way switch in it, acting as an encoder.
I did wonder if it was one of yours when I opened it :D

I've not looked at the return rollers yet, but they're now quite stiff as well.

Home made axles

Post by Adrian Harris » Fri Sep 04, 2015 11:23 pm

I've been plugging away at this Panzer III, in between work and other projects. I'm finally getting the hang of stringing a program together on the CNC lathe, so thought the suspension would be a good place to start.

Blanks all lined up in readiness:

These have been cut from stock on the chop saw and then faced to the correct length on the manual lathe.

The parts after machining:

The only task left now is to thread the ends to M4 for the wheel retaining end cap bolts.

Hopefully, I'll be turning the suspension shafts and end caps over the weekend, so that will be the suspension sorted.

Adrian,
The axles look fantastic. Congratulations on getting your lathe running. One question - the axles look like brass. While wonderful to machine, I'd be afraid brass would be too soft for functional axles? Perhaps these are practice pieces? Not meaning to "rain on your parade" so to speak - just hate to see the work you have done go to waste if they bend or break. Axles take a lot of punishment on these heavy models. Free machining <leaded> steel, 12L14 or similar would be a good choice for axles.
Best regards,
Great work!
Bob

I agree it's a risk, hence I'm trying out on this Panzer III and Sherman to see how I get on.

Hopefully, the ground-pressure spreading effect of running on tracks means that the weight distribution will be spread between the axles. Unless I run it into rocks or kerbs, I'm optimistic they'll be up to the task.

The Sherman is less of a worry, as all the axles etc are supported at both ends, so there isn't the same cantilever effect as with the Panzer III.

Time will tell, and if they are found wanting, I will have the necessary program to make new ones from steel 8)

Today's task was making the axle end caps. Once the program was tuned for one, I expanded it to make batches of six.

One of the real benefits of doing this on the CNC lathe is that I can put in the odd ends of bar which I have left over from trial runs, and the program will work its way up them cutting air, then make as many as it can from what material is there 8)

Adrian,
Looks like you have the lathe dial in - great parts. Wish I had room and $$ for a CNC version. Agreed - I think the Sherman would be fine with brass axles, its those long slender cantilevered ones on P3, Panther etc that would be at risk. But what the heck, you have em made - give them a thorough run through!
Best regards,
Bob

A quick five minutes in a text editor to change the diameter:
DSC_2632.JPG
and I've got the end caps for the return rollers.

It's a larger bearing, so I've made the end cap larger, even though the kit uses the same size for both. More for the hell of it than any technical reason :lol:
