DIY Mandolin Rail for Tack Piano effect?

I've seen several videos in YouTube for pianos that have Mandolin Rails. These devices are felt strips attached to a metal "rail" that can be swung in and out of place to give a normal sounding upright piano a ragtime sound. They look pretty simple to make, but I have not found any webpages with instructions on how to build one. Anybody have any input? Most of the materials look like they would be readily available, except for the 88 metal tabs that go at the end of each felt tab. I found a website that sells the tabs pretty cheap  Here are a couple of YouTube videos that show Mandolin Rails in action:;=player_detailpage

Knex Ball Machine - Splat

This is a small ball machine that I made while I was sitting in my bedroom thinking about my childhood. I was origionally going to post it, but it didn't quite turn out the way I intended. Its small, and is fun to show to guests and whatnot.For those wondering about the name, me and my buddy had just finished editing the video. I realised that I needed a name for it, and just that moment my buddy's bird puked on my head, making a splat sort of sound. Presto, the name splat.Since the video wasn't going to be anything special, I put it to ragtime music and aged it accordingly. Hope you like it!IaC EditI've counted the pieces. Just for the heck of it, I'll run a little contest to see who can guess closest to the real number. The prize is a virtual high five and cookie. Closes on Friday.Updated - Winners!The correct answer is... (drum roll)... 1749! This means that cj81499 is the clear winner, being off by only 14 pieces! Good job, and congratulations! Thanks for guessing everyone.
