Eds Medieval Madness Pinball Machine


Posted on Feb 5, 2014

This machine`s playfield features a catapult that fires the pinball, trolls that pop up from the playfield, and an exploding castle with a drawbridge and iron drop-gate. All the plastics were replaced with a New Old Stock (NOS) set from Marcos Specialties. I also bought various parts such as target switches, the steel castle gate, and dragon wings.

Extensive use of laser printed graphics were used to make overlays and decals such as for the castle drawbridge, troll flaps and other locations. The plastic ramps were stripped, cleaned and then flame polished. The metal ramps responded well to a rubbing of `Brasso` (unlike the IJ ramps, which did not), and came out bright and shiny. The edge of the castle gate was broken on the left hand side, so I decided to purchase a new one. However, when it arrived, I saw how little was broken, and decided to repair the existing one. Using fiberglass tape and epoxy, I rebuilt the left entrance. I also touched up the footers of all the towers and clearcoated the entire castle with non-yellowing polyurethane. This is the method first developed on the Space Shuttle ramps. I started by shooting a photo of the area with a ruler in the field of view. A resolution of about 300 dpi is a good target to achieve. I then edited the image to add the missing parts back in with PhotoShop. The image was then printed onto both photo paper and vinyl media from mediastreet. com. The former product is 6. 8 mils thick, while the latter is 6. 5 mils (normal office paper is 4 mils). I found that the former worked better in terms of the image quality in the solid areas. Whenever the vinyl was stretched, the colors would crack, so I used photo paper. I then glued the paper down with dry glue from a glue stick (prevents wrinkling of the paper), and covered...
