Hi guys just a quick update:
Today i rebuilt the drop targets. Since i couldn't find some yellow plastic anywhere i decided to use the same 3mm clear polycarbonate to remake the target faces, and print out the art (along with the yellow colour) onto clear adhesive and stick it to the back of the target.. same deal as making playfield plastics. 1st pic shows me tracing out the old target shape ready to be cut out, and the 2nd pic shows my printed artwork. the artwork was a pic i found on ipdb, resized and cut/pasted in photostudio into the scans i took of the original target face.. worked out pretty well i think, a nice and easy fix to the target problem.
Last two pics show one of the target banks after being pulled apart, cleaned and rebuilt. I had to make new links for the plungers as the metal originals were fairly worn. I used fibreglass pcb material, two pieces superhlued together to double the thickness, and thus help extend their life expectancy. I've used this trick on flipper plungers as well, and they seem to last pretty well.
