Based off the design of lecturer Milo’s casing and mechanism designed to convert the movement of a solenoid to a striking action. Originally made for a small beater stick, I have adapted the design to fit the measurements of the larger diameter beater traditionally used with gangsa, as a result being larger and weightier in turn affecting the adjustments I made to the design. For example, the lever that attaches the solenoid arm to the beater has been increased in length for the increased strength to carry the larger weight as well as more stability to hold the larger circumference beater. I have decided on using PLA plastic for the material to synthesise the casing out of for three reasons. It isn’t as damaging to the environment as conventional petroleum based plastics, it is the plastic used in 3d printing, a process which I already have experience with and it is strong and lightweight, a good material to use for a repetitive mechanical role.

The first prototype had some design flaws because I took slightly inaccurate measurements. For the second prototype I will fix this issue and make minor adjustments that will improve the mechanics hopefully to achieve a smoother transfer of movement between the solenoid and the beater. This will in turn improve the power at which the beater strikes the gong which I worry will be weak and not strike the gong with enough force to produce a sustained and loud enough strike. The gongs are often struck hard when played traditionally so it would be important to mirror this.
