Quoted from mbeardsley:Sure, there are new items made for each title, but, the cabinets and playfields are not "hand built".
You do realize that CGC is the same company as Churchill Cabinet, right? They've been making cabinets and playfields for many decades, so they already have the experience and tooling necessary to make widebody cabinets/playfields.
I don't know if you've seen this, but it's a fascinating look into the factory:

There are certainly CNC machines and presses, but for the most part everything is hand assembled. The playfield inserts/sanding/screening/clearing are all manual processes.
Edit - I found the pic I was thinking about. Here is an original TZ playfield stamped "CCC" (Churchill Cabinet Company). So there you have it - CGC actually made some of the original TZ playfields long ago! So yes, they have all the tooling needed and perhaps even the original silkscreens.
