For this assignment, I would like to create a balance bike for children aged 2 to 6 years. His name will be Alberto Marzaioli, the greatest cyclist that my city has ever had.
I started by doing some research on the different models of balance bikes on the market; my main desire is to create a design that evokes that of motorcycles.I want to create a hybrid design between road bikes and naked bikes
After doing all my research I started doing some sketch on paper, looking for the desired shape for the bike frame. Here following some sketch
After doing this I moved on to creating the actual Design. The software I used:
Here are some pictures of the final design.
To make this balance bike, use 10mm poplar plywood. Overall, the bike enters in two sheets of 500x700mm.
After creating my Design, I exported the sheets that I will go to mill later.
Currently at the KromLabòro FabLab, we do not have a large milling cutter. To get my project done and to complete this assignment, I asked Arch. Amleto Picerno Ceraso (Director of DREAM FABLAB, Mediterranean FabLab and Centro per l'Artigianato Digitale) he offering me technical support and the milling machine supplied to the C.A.D. (Centro per l'Artigianato Digitale)
I have prepared my gcode with RhinoCam, using the following settings, tools and machines:
In the following image it is possible to observe the two working processes adopted and the layers associated with them. Cyan color layer: Holes, internal tool path
While for cutting the edge, I obviously chose an external toolpath
As you can see in some photos, we have further fixed the pieces to be cut using screws and brackets to prevent them from slipping away during the cutting process. It is possible to solve this problem by using also "Open Tab" inside the drawing, these must then be removed and polished, and then a further post processing
To give the balance bike a more pleasant look and a greater solidity, I designed and printed some parts that I subsequently assembled to the previous work
Here an image of the assembled piece:
Below, the handlebar connector printed in two threaded pieces:
My Balance Bike was selected to participate in the Maker Faire Rome 2019 and it was really a great success. The bike has pleased many Makers like me, who intend to replicate it in their workshops.
