I follow the instructions. Most of the time I fold them so that the grooves face inwards (instructions call them "the cut lines"). Some are bent inwards, some outwards, and in some cases a part can be bent both ways (i.e. one edge of the part bent opposite direction to fold of the other edge) Here (Figure 21) they are bent inwards: Here (Figure 83) they are bent outwards: -
Figure 119: Alright, I have now installed the control system and repainted the bogies with my airbrush. Installation of screws and nuts did not go perfectly at every spot, e.g. sometimes I had to use superglue where I couldn't fit the nuts, but I am overall happy with the result. As per the discussion about the paint on the wheels touch surface, I don't know yet if I will remove the paint on those surfaces or not. At least this way, they are compliant with the instruction manual. I guess I will stop now for a few days. The missing L-profile, which acts as a support for the body work, has been dispatched by Amati and is on the way. It should arrive during the week. I need it in order to continue. I am also rather busy with other daily work. That's all for today! Thanks for watching!

Figure 118: Preparing for airbrush paint. This is a nice tool I bought on Amazon. I had been missing something like this for my paint jobs. Very handy indeed. It also has a storage, you can store the sticks in it when not in use. The crocodile clamps come with removable rubber covers (removed for this purpose) for grabbing sensitive parts without harming.

BUILD DAY 8: 4 hrs (TOTAL: 27 hrs) Figure 112 : A close-up to the brakes. Not all 16 of them came up this neat 🙂. This particular one in the photo has been my best installation of the inner-side brake shoes. At least with my skill set, even after so many done, it still feels pure luck to put those tiny nuts and bolts correctly. 🤣

A good news today is from Amati. They have just dispatched the missing part from the box. It is a brass L profile for the sides of the body structure. Because of the lack of it I couldn’t proceed as planned, I had switched to building the bogies in the meantime. Now the bogies are almost ready and the package should arrive sometime next week, just in time to resume the body work. Thanks Amati.

Thanks for the good tip, Yves! I will actually go through the entire painting details on the bogies once they are fully ready. There are many unpainted small parts as well as scratches caused by using tools. I’ll keep your points in mind then. I use acrylic paint hence removing it off the metal surface should not be a big deal, hopefully.

Figure 111: First brake shoe installed. When installed it swings freely on the bolt. I used superglue to fix it in position, just as close and parallel to the wheel. The brake shoes on the outer side are rather easy to install. However those on the inner parts are very very tricky to even fit at first place, let alone insert the bolt, tighten the nut and glue to the right position. My recommendation to a builder reading these pages would be to consider installing the brake shoes before installing the wheels. That's all for today! Thanks for watching!

Figure 110: Brake shoes, consisting of two parts assembled with nut and bolt. There will be 16 of them, one pair for each wheel. In the middle you see one of them assembled.

Figure 108: Testing the bogies together on the rail to ensure that they are aligned. If one is higher than the other, then there is a risk you'll fall from your bed in the night due to inclination 🤣. So far looks fine and I can glue the bearing blocks holding the rods in place.

Figure 107: Wheels dry fit. The wheels are not supposed to be glued. They should rotate freely and independently. The rod will stay still. This is needed especially for the rod above, which is connected to the dynamo via a brass belt. I see some build videos in Youtube gluing everything to the wheels including the brake shoes (to come later in this log). Such approach is only for in case you are absolutely sure you are building a fully static version, in which the wheels will not move!

Figure 106: This wheel set differs from the other three by the additional wheel on the rod. It is for the belt turning the dynamo.

BUILD DAY 7: 2,5 hrs (TOTAL: 23 hrs) Figures 99-102: This is how I bend this kind of small and thick brass parts. I used plier's handle as a hammer. A soft rubber hammer would be a more proper tool for this purpose.

Amati has replied to my request, they are sending the missing part. Fingers crossed 🙂.

Installation of the dynamo. This part is only on one of the frames. Figure 91: Dynamo is installed using 2 bolts and nuts, which need to be shortened to size (10mm and 7,5mm) and must fit in the dynamo. Well, except once again they don't. Hence, drill. 🤣 Figures 92-98: Showing the process of dynamo installation. That's all for today! Thanks for watching!

Figure 87: The so called "struts" and springs. This will be the structure where the wheels will sit on, later. Figure 88: Painted in matt black as usual The springs consist of 3 parts to be glued together. But I choose a bit different order than in the instructions, to ensure accurate alignment: - First I glued the two parts which will be on the side of the struts (like in Figure 89 below), - Then screwed them to the struts - Inserted the 3rd part of the spring structure to the frame - Finally placed the struts on top od that 3rd part. Figure 89: Figure 90: Now everything looks perfectly aligned.

Figure 85: Suspension structure painted and mounted in place. Figure 86: How to mount the suspension structure to the frame. See the brass rods connecting on left and right side. Altogether four of them. They also use copper rivets to allow the suspension to move.

More photos on the assembly process. Figure 82: Dry fit on the springs, for aligning the small parts on the left side of the picture, to be glued on either side of the brass component. Figure 83: More drilling. The holes are simply too small. They are almost there only for a reference of the correct location :).

BUILD DAY 6: 3 hrs (TOTAL: 20,5 hrs) Continuing with bogies. Now the frames are ready, it is time to fill them. Note: The manual is instructing to finish one of the bogies first and then repeat the almost identical steps to build the second one. I will not follow this approach fully, nor a parallel building progress. Instead I decided to go with a "hybrid" approach. I build some pair of components at the same time where it looks more convenient and keep them aside until I build the second bogie. Next on the line is the suspension structure. There will be two of these. Figure 77: Die cast parts. Figure 78: You will need to enlarge almost every hole by drilling, in order to fit the bolts conveniently. Do not try to push/pull the bolts with pliers or other tools to pass them through the holes, their pitches will get ruined very easily and the bolt will be impossible to use. Better open a wider hole and just insert the bolt smoothly.
