Guys,
Finally finished the drop targets. In between keeping the wife and kids happy, it’s only taken me a month and a half.
I got a little carried away and ended up replacing the drop target springs as well so that they all dropped even (some weren't dropping right down).
Anyway I used Avery Inkjet label paper and put a clear laser label over the top (the laser labels I bought above that didn't fuse properly).
The results are below.
On another note (I'll probably post this as a problem) - when a new game starts up, different targets in the Meteor bank will intermittently drop down straight after being reset - has anybody had a similar problem before? Any advice?
