What was used for the Wormhole emitter?
I know a pioneer speaker grill was on the front of it.
But what exactly was the main part of it?
The main body of the wormhole emitter is one of very few parts that has not be positively identified. No one has ever found one "in the wild" at a surplus yard or parts supply house. Most people build these from scratch using reference photos to get the scale correct, or use castings of the real parts from the A/B car.





A few basic dims of the casting from the USH Ohrberg replica.





The pioneer speaker grille was first discovered by members of the time machine restoration team. More information about that can be found on the TMR facebook page. Parts show up on ebay all the time but prices have gone up since the info was released.

The base of the WHE is fabricated from scratch and welded together from 1/8" aluminum sheet and aluminum box channel.
