Quoted from dzorbas:

In case anyone needs to replace their rails, you can get Taylor to make them for you (https://pinside.com/pinball/forum/topic/oak-replacement-playfield-rails-wh2o-and-taf-ready-to-ship-or-york).
If you are handy and have access to a table saw, you can do it yourself cheap and easy. The rails are 1-1/8" high and 1/2" wide in various lengths. You can use the following for the material:

When you rip the piece with the table saw you will have enough left over to run it through again to make a second piece. Cut them to length, sand all the edges a bit just to remove the sharpness. Paint or stain them whatever colour you like. I ended up making mine black but thought about red or blue or some combination. The paint/stain will probably cost you more than the material!
This is definitely not rocket science and I think they look a lot better than that fake oak wrap that was used in the factory!
