Today on a small road trip I listened to a spooky pinball podcast which Charlie talked to a guy named Wally that decided just for the challenge was going to build a Medieval Madness from scratch from parts he could buy salvage and make. The total cost was around the $7k and invested over 1000hrs into the project. So it can be done but a massive effort - more of a labour of love.
Here is Wally's story
"I’m retired and have been working on building a MM from parts for the last 15 months as a hobby. It has been a very challenging and enjoyable project. I didn’t work on it every day and usually only for a few hours at a time. Some weeks not at all. Any frustration meant quitting for the day. In retrospect, it has probably helped keep me from making any big mistakes. The first four months were spent searching for parts and building assemblies. Much time (most of the summer) was spent preparing the cab/head for decals, something that I have never done before.
Early on I came to the conclusion that it would impossible to build a MM without having one on hand to get some critical measurements in order to fabricate parts that were not available. The wiring harnesses would also be more difficult without a sample. Since none were near, I bought one with the thought to restore and sell it. My plan was to replace the playfield, plastic ramps, all three castle assemblies, all playfield plastics and posts, clear plastics, dragon/wings, side art, apron/backboard decals, trim, targets, updated Mantis castle gate assembly, troll assemblies, translite, DMD, coin door, lock bar, legs, glass, side rails and so on. As a matter of fact, the ball guides, metal posts, and wire ramps are probably the only parts on the upper playfield that aren’t new. The old parts would then be used with my own harnesses and other hand built parts to build a “player pin” to keep. This was my first attempt at a complete restoration. I don’t feel like I am in the same league with some of the restorers that are on the forums and would not call my restored pin collector quality or mint or anything like that. I consider myself just an average pinball enthusiast with some time and patience. I usually did a lot of research before attempting any portion and didn’t mind redoing something if it wasn’t right. This worked for me since I had no schedule to meet, and could play my other MM in the meantime to keep my enthusiasm for the project up. I really not a collector, so keeping a player type pin works just fine for me.
I bought a donor routed WPC- 95 pin (NBAF) to keep costs down and obtain some rare parts like the backbox lamp insert panel or tub (which had to be modified), transformer, speaker panel plus just a big supply of parts (flippers, slings, jet bumpers, ball trough, auto fire) , not to mention all of the WPC-95 boards. Only minor modifications were needed on the cab such as drilling a hole for the launch button and removing some cabinet wood so that the castle would clear like on the original.
I built the wiring harnesses myself from the schematics and using a wiring template/ fixture that I made. There were six major harnesses to build; solenoid/flash, switch, feature lamp, GI, backbox GI/flash, and opto. The original design has the feature and GI together but it was easier for me to split it into two. There are also some small harnesses for the drawbridge opto, back board lamps and plastic ramps. Sections of all NBAF harnesses were modified to work in the MM, especially the solenoid/flash. Overall, quite a bit of the NBAF wire was reused. My son came up with a simple tool to stripe (color code) wires. Exposed wiring for the ramps was purchased from BAA.
I also made the wooden side rail and back panel, hex posts, gearbox shafts, and other metal parts that were not available. There are 14 hex posts that had to be cut, drilled and tapped for 8-32 hardware. The two gearbox shafts were made with an improvised lathe (drill and dremel). There are 22 additional individual metal pieces that had to be fab’d. Fifteen were ball guides. All metal pieces had to be removed, measured, and put into CAD files. I wanted them originally high pressure water or laser cut but had to settle for plasma due to resource availability, not technical issues. A lot of time was spent polishing, grinding edges, and re-drilling holes in the 18 ga stainless. Every metal part had to be bent. Some were a lot more complicated than others. A small metal brake (18 in Harbor Freight) was used to bend the parts. Four wire ball guides were bent from 1/8 inch rod. (one was available)
A template was made in order to cut additional holes in the NBAF backbox insert panel so that the lamps would be in the same position as the MM.
I gave up looking for two of the wire ramps (I actually found a Peasant Ramp) and was practicing bending 1/8 in rod and then by luck found a metal sculptor who said he could duplicate the originals. He has made the Catapult and Right Wire Ramps with stainless rod. Up close, they wouldn’t pass as originals but they look fine in the player pin and the TIG welds seem to be a lot stronger than the original spot welds. Maybe later I’ll get these plated but they look pretty good in stainless.
At the present time the player pin is complete and running with the NBAF board set, new ROMs, used plastic and castles parts, used playfield and plastic ramps, all handmade harnesses, hand built metal parts, and the custom catapult and right wire ramps. I have not done a lot to this pin, basically a good cleaning , flame polishing the ramps, and replacing decals on the drawbridge and troll flaps.
The restored pin is also completed. It is being play tested to make any final adjustments. It is amazing how different a pin is with a new playfield. It is really fast and smooth. I can make shots much more easily than on the player pin.
Having been through this, I believe that a person with some moderate metal, woodworking/painting, soldering, and electrical skills could build a replica MM for under $7000 (minus labor- lol). It, of course, would not be as valuable as an original but would have many, many new parts as I have outlined in my restored MM link below. This estimate is based upon procuring each part from the lowest cost vendor, taking advantage of the good deals found at pinball shows, building assemblies rather than buying completed ones, finding a donor WPC-95 relatively inexpensive (under $1500), and having an actual MM close by. If you have welding skills and can fab the wire ramps, the cost would be a lot less. The time commitment is huge. I bet I have over 100 hours invested in wiring harnesses and over 100 hours in making/bending metal parts alone.
Recent part searches have led me to the conclusion that this project if started now would be a little harder (not impossible) because some parts are getting more difficult to find. For example, I can no longer find some lampboards. That results in the need to use individual IDC sockets for the feature lamps like Stern uses.
Big thanks go out to the vendors who have made parts available, especially those who remanufacture new parts. Also to all who post restoration tips/pics/ideas on the forums. (Clay’s DVDs and Bryan Kelly’s gallery of restoration tips were especially helpful.) Thanks to Gary Martin and Eric Schmitt who originally posted on RGP in Aug 2010 that a project like this was definitely doable and got me thinking.
I have over 1000 pics of the process and have included a portion in the link.
If any of you are ever around Frankfort Il and would like to see the player MM, contact me and stop by. There is a buyer for the restored MM and it is going to be picked up in a week or so.
