Sometimes a need arises for a pinball part that is not easily obtainable. It could be a part that is obsolete, rare, or needed to work with available aftermarket parts. I've tried making several parts to replace what is not available or sometimes to improve gameplay or overall aesthetics.
Starting with something simple, new aftermarket drop target assemblies for Classic Stern games sit a bit lower on the playfield than the originals. The overall height of the new targets were slightly shorter.
When installed the targets are less than an inch above the playfield in the raised position.
To raise them up I added a new "lip" that the targets rest on to the drop mech assembly.
With the new bracket in place the targets are a respectable 1 1/16 inch above the playfield.
Post some pictures of parts you have made to make your machine play better.
