On my Funhouse and TMNT, I had broken ramp entrances which were causing
problems during game play. Fed up, I decided to fix it by doing this: Went
to a home improvement store and picked up some 'flash' sheets (~$0.23 for
a 5"x7" square) and some 3M mounting tape. 'Flash' sheets is a really thin
metal used along gutters and eaves. Using metal snips, I cut these 'flash'
pieces into strips which mirror these sides and intake of the ramps. I used
the mounting tape and stuck the 'flash' pieces to the sides of the ramps. I
folded the edges of the 'flash' sheets to protect the pinballs. It's easy,
it works, and it looks good.
