TZ Piano mod how-to

  • My friend wanted me to build a few mods for his Twilight Zone. He found these hanging piano ornaments, I'm not sure where though. They are a sort of like low density fibreboard. As you can see I already started the modding before I decided to document it. Seems to be a pattern with me :)

  • Disassembly isn't too difficult as its held together with wood glue. Yank the plastic pieces out and use a razor to score along joints so the fibreboard doesn't flake and tear.

  • Since the piano needs to squeeze under the clock we need to know how much room we have. Looks like we have an inch and a quarter at the biggest height.

  • ...and we can go inwards up to about 3 inches.

  • More disassembly. I'm leaving the rightmost piece attached though as it should not need to be trimmed.

  • Here I'm trying out a good balance of height overall and a good looking fit for the keyboard tray. Basically I want as much of the mantle at full height as possible yet make the keyboard feel believable.

  • Clock mount plate removed showing the lamps that will need to be relocated as well.

  • Lamps removed. See the little stamped loacating bumps? Those will be filed down flush to allow the piano to slide in.

  • The piano we are using is a model of a spinet. What we want is a player type to match the playfield art. As it so happens I make a line of way cool color bumper post sleeves. Of the 9 colors one of them is white. How convenient! :) Using my trusty single edged razor I slice a profile out that I feel will model the player pin drum effectively.

  • I just want the smaller of the two sections and I'll sand the cut side down smooth and even.

  • Test fit for appearance. Looks darn good to me! I'll sand those pressed-in whoop-de-doos later to allow the drum to sit a little higher.

  • I decided on a 2-3/4" depth so marking it out here for cutting.

  • The lamps too determine our keyboard tray height. Mark this.

  • Drilling out for one lamp with a 3/8" brad point drill. This bit keeps shredding to a minimum. A tapered reamer helps get the fit just right.

  • Lower hole drilled and we see that the webbing between the holes is practically non-existent. May as well sand or file it out into a nicer looking oval.

  • Better! Even with the sockets sticking all the way into the piano body that lower lamp is still fairly hidden. However, a test layup in the game shows that it's inclined enough towards the player to be completely visible. Yay!

  • Now we just need to bend those lamp socket tabs down to the piano body for mounting.
