Looking Good Kerst.
The box is a work of art for sure.

Re: Demag TC 500 truck crane in scale 1/24
 

I finished the outrigger boxes. The vertical movement is hand operated with a screw thread inside, very simple.

I put the FAUN carrier together again. Apart from a few details (never ending!) the carrier is done.
I have started with the drawings of the upper works.

That is one great piece of work! I'm sure the upper works will be awesome, as well. I've really enjoyed seeing this come together.

I made some good progress with the upper of the crane. It is based on a ¼” piece of AL with the two main frames of brass. I found some nice small gear motors to drive the 2 main winches, boom hoist and the winch for the luffing jib.The motors fit nicely underneath the winches. It looks like I even have room to spare.

Thanks for posting more ideas for projects

The past week I worked on the swing gear. There is plenty of space for the whole assembly, so that was no problem. I added a spring-loaded clutch. I tried it and it seems a bit fast, so I might add a reduction later.

I like the slip clutch!

Re: Demag TC 500 truck crane in scale 1/24
 

This is better. I added a reduction , so now the swing speed is perfect.

That looks like a nice set-up. I enjoy seeing gears on anything. Good looking gears also. What is the purpose of the clutch? Great work so far!!!

The winches are taking shape:

It is summer and I haven’t had too much time for the hobby. I worked a bit on the enclosure of the upper. It proved to be more complicated than I expected, mainly because I couldn’t agree with myself which method to use. It turned out to be a combination of brass and AL. There are quite a few angles that make it complicated. But it is getting somewhere.
So far:

Kerst. It's looking good ! I keep follow you're build for sure. Next event i might need lifting help......:D

Re: Demag TC 500 truck crane in scale 1/24
 

The summer has been slow. Too many other distractions. And often it was simply too hot in the workshop.
I continued working on the enclosure of the upper and built the cab. I am quite happy with the cab. It came together nicely. I am still not really happy with the enclosure. The idea is to be able to remove the side panels easily. The interior still needs to be done. The door is ready, but the front window not yet. There are still lots of details to be done. The next step is connection the electric wiring.

Can you put some of those tiny neodymium magnets on to hold the panels?
I want to try to use them on my 9W someday to hold the house panels on that need removed easily.

Re: Demag TC 500 truck crane in scale 1/24
 

I used them for some smaller panels like the one on the truck just in front of the first rear axle.

During the past month I worked on the sheaves. They are the same size for the boom hoist and for the boom tip, 22 sheaves total. The difficulty was reproducing the spokes. After a couple of trials I figured out a way to make them. Basically there are 3 parts, the outer part, the spokes and the center core. I made the outer part from brass tube.This was pretty straightforward. The spokes were very labor intensive. I made them from 1/16” brass sheet, turned them to size and then milled the spokes out, 4 at the time. Then I soldered the parts together in a simple jig and finally finished them on the lathe in specially made chuck.

Love the detail!! That's one thing I usually get too eager to finish and skimp on detail stuff. But that is what separates good work from awesome work. And love to see your ideas in set up jigs and customs tooling. I keep forgetting to complement you on your models when I see you!! I guess me starring at them speechless probably says more :). And also at a very small scale!!! I remember you saying about why the scale you build, realizing most rooms don't have high enough ceilings for larger scales!! Great work kerst!! Always enjoy any posts you share!!

Re: Demag TC 500 truck crane in scale 1/24
 

I know the pain in making several sheaves alike. I made 18 for my boom support cables. I showed step by step how I did them.

Re: Demag TC 500 truck crane in scale 1/24
 

Those sheaves are incredible!
