Tamper De-wiggler

This part allows you to make your cheapo Aliexpress "self-leveling" tamper actually self-leveling.
 

First, disassemble your tamper into all of its parts and grab your new dewiggler.

Now you insert the dewiggler into the plastic coupling. Be sure that the flare on the dewiggler is on the threaded side.

With the dewiggler in the plastic dealio, now screw the plastic dealio into the leveling plate.

Now reassemble the leveling plate back onto the shaft, place the spring over the shaft and tighten the handle.

Congrats! Your $7 tamper is now actually self leveling! Go reward yourself with a nice drink.
