People have been waiting for updates on my projects for a long time, so here is the reason nothing new has appeared here.
My SolidWorks 2017 struggled heavily with modelling extremely complex surfaces in many parts, which caused long delays.
I have designed several different roof versions, including interior felt‑covered elements, a cabriolet roof, Targa high and Targa low models, and a rain hood for the Economy model.
Two years ago I began designing a motorcycle caravan, after learning that it could legally be 1.5 meters wide and that no serial‑production caravans exist.
Main specifications
Sleeping space for two people. Interior dimensions approx. 1070 × 1850 mm (with optional floor heating).
Possibility to sit and eat inside, even in rainy weather. Maximum interior height 1600 mm.
The main lower body is made of fiberglass or carbon fiber, with a smooth interior surface. The interior walls can be easily covered with any preferred material.
A large front trunk for luggage and equipment.
Aerodynamic shape, slanted front surface, modern design.
The ABS plastic exterior panels imitate the motorcycle’s design language (BMW K1600, Honda Gold Wing, etc.) and are designed for easy replacement.
Each ABS panel can be wrapped or painted to match the motorcycle’s original color.
Compact foldable chairs and tables that can be mounted in various positions for dining.
Design progress
In the design process I’ve reused as many components as possible from my sidecar, including several parts made with the same molds. I’m now at a stage where, although there is still plenty of work ahead, the lower structure (bottom body) and exterior surfaces (panels) are already very close to their final form. The biggest unfinished areas are the detailed modelling of how the parts connect to each other and the conceptual design of the rear door.
Because I’m using many of the same shapes and components from the sidecar project, I’ve had to make small adjustments to numerous sidecar parts as well — often only a few millimeters — but this has taken a huge amount of time. I expect to finish these minor modifications within the next few weeks, after which I’ll publish the final images and officially start the project (including the modified parts, roofs, accessories, etc.). The prototype build of the motorcycle caravan will probably begin toward the end of the summer.
Sidecar project status
The 3D model of the sidecar is now so close to “finished” (if such a thing can ever be said) that prototype manufacturing can begin. All the plugs for the fiberglass molds have already been CNC‑milled; a few adjustments will be made, the surfaces will be sanded and painted, and then the production molds for both fiberglass and carbon fiber parts will be created.
Since almost all exterior panels will be manufactured from ABS plastic using vacuum forming, I need to build my own vacuum‑forming machine so I don’t have to reserve time from a subcontractor every time. That will be my next design task.
There are still other modelling tasks on the list as well, such as 3D scanning and modelling the new Japan‑built Honda GL1800 and finalizing the design of the corresponding rear section. I’ll order the scale model at the turn of next month.
In the near future I’ll also set up a website and start experimenting with 3D‑printed scale models.
