Beside using my creativity for professional uses, I also enjoy applying my skills to small projects in my free time. Some examples of these are:

Handheld potato gun

This was a project to make a scaled down potato gun with paper darts, powered by combustible gases in spray cans (hairspray for example). The first image below shows a proof of principle in rifle form. The other two images are of the final product, shaped to resemble a colt revolver.

 

Airgun

Similarly to the project mentioned above, this riffle was intended to fire a small dart. This time compressed air would power the projectile. The riffle can be loaded with an air compressor or bicycle pump. The images below show the proof of concept, improvement proposals were sketched in CAD, but never manufactured.

 

Bow and arrow

A test to see how easy is would be to build a wooden bow. It consists of a wooden, ergonomically shaped handle, nylon fishing line bow string and stressed members made out of laminated bed slats (the flexible planks which support the mattress). The arrows were made from bamboo shafts.

 

Motorcycle adapter plate

With the purchase of a new motorcycle a the mounting plate for the luggage case was no longer compatible. Rather than buying a completely new set of cases, I designed an adapter plate with would make mounting possible and would provide flexibility to tweak the position of the case on the bike. The design was based on an aluminium (to reduce the weight) plate of 5mm thick for rigidity and to create room for the countersunk holes on the edge. The shape made by waterjet cutting and the countersunk holes made by hand afterwards. Below, you can see the CAD model as send to the waterjet cutting machine and the finished and mounted product.

 

Motorbike and moped restoration assistance

On many occasions I assisted my brother with his restoration projects of vintage motorcycles and mopeds. These projects include multiple Kreidlers, Zündapp, Solex, Honda CB125, DKW, Vespa, Peugeot, Motorchaise, etc. My involvement consisted of assisting in (dis)assembling, spray painting components and troubleshooting mechanical issues.
