The solenoid is inserted into the holder. The solenoid holder is attached to the standoffs on the base with M3x6mm screws. The linkage connector is pinned to the solenoids plunger with an M3x16mm screw and locknut. The linkage mounting plate is secured to the solenoid holder with M3x6mm screws. The linkage is then secured to the mounting plate with an M3x16mm screw and locknut. M3x10mm long standoffs are secured to the base for evelation.
Kick Drum Assembly
The solenoid is secured to the mounting plate. Two mounting brackets are secured to the slotted holes on the mounting plate. The brackets slide onto the profile of the 2020 extrusion and secured with M4x8mm screws and slim t-nuts. The base mount is secured to the 2020 extrusion with an M4x8mm long screw and slim t-nut.
This selection analysis shows the linear motion of the plunger pushing the linkage bar and pivoting at the joint to make the mallet strike. This was created in Fusion 360 using joints and contact sets. Revolute joint type is used in the pivoting point in the linkage bar. Slider joint type is used in the plunger of the solenoid. Contact sets are created between the linkage bar and M3 screw secured to the plunger.
No supports are required. Slice with settings for PLA material.
The parts were sliced using CURA using the slice settings below.
- PLA filament 220c extruder
- 0.2 layer height
- 10% gyroid infill
- 90mm/s print speed
- 60c heated bed
