YOU NEED FUSION 360 OR CAD SOFTWARE TO EDIT AND CREATE CUSTOMISED 3D PRINT FILES FROM THE DESIGNS. YOU MAY NEED TO ADJUST THE DESIGN TO SUIT YOUR PVC PIPE SIZE AND SHAFT DIAMETERS.
Let me introduce you to my updated Boeing 737 Dual Yoke roll channel. This time the 3d printed gears are replaced with cheap readily available metal gears and the design is mechanically adjustable. This simplifies the build and reduces the need to change anything in fusion 360.
This design utilises 3d printed parts and metal gears to improve the build quality. As seen on my YouTube channel, It works really well and now includes the modification to stop the yokes turning past 90 degrees.
The tighter the gears, the less play in the system.
Each part can be 3d printed and edited to suit your needs. (less hardware which can be found/listed from the fusion Browser on the left - This includes nuts/bolts/bearing etc.) I have already issued the metal framework plans for free. These are designed around using 3mm thick, 38mm square stock steel.
Kind Regards Karl & Helen.
