Install Solenoid
Install the solenoid into a holder by sliding it in with the piston fitting through the center hole. The mounting holes should be lined up with the holes on the side of the holder.
Secure Plate to Holder
Insert and fasten 4x M3 x 6mm long screws to secure the plate to the solenoid holder.
Hardware for Base
M3 standoffs are used to elevate the solenoid. Taller standoffs allow for more height clearance. Choose the length of standoff you'll want to use for your setup. In this project, 10mm long M3 standoffs are used.
Install Solenoid Holder to Base
Place the solenoid holder over the standoffs on the base. Line up the slot with the M3 standoffs.
Mallet Hardware
Super glue the two dome halves to make the head of the mallet. Glue the head to the mallet stick. The mallet is secured to the linkage using an M3 x 16mm long screw and lock nut (with nylon insert).
Secure Mallet Parts
Place the mallet stick over the linkage with the mounting holes line up. Reference the photo for best placement. Insert the M3 x 16mm long screws through both mallet stick and linkage. Insert and tightly fasten the M3 locknut.
Installing Mallet to Solenoid Plate
The assembled mallet and linkage will be secured to the linkage plate on the solenoid holder using an M3 x 16mm long screw and locknut.
Install Linkage to Solenoid
Fit the linkage through the slit on the end of the solenoid with the large spring. Line up the mounting holes.
Secure Linkage
Insert the M3 x 16mm long screw through the mounting holes. The screw will go through both the solenoid and linkage. Install and tightly fasten the M3 locknut onto the thread of the screw.
Install Linkage to Plate
Line up the center hole on the linkage with the mounting holes on the linkage plate.
Secure Linkage to Plate
Insert the M3 x 16mm long screw through the holes in both the linkage plate and the linkage. Insert and tightly fasten the M3 locknut onto the thread of the screw.
Test Motion
Press the piston on the solenoid down to test out the mallet. It should actuate the mallet down and spring back when released. Loosen the locknut if the motion is too tight from the friction.
Degree of Rotation
The 12V solenoid features a push / pull of 10mm throw. The mallet has about 18º degrees of rotation.
