I needed the screw measurements for the sensor panel screws, and I remembered this article, so I was looking for it. I saw indyddr had changed, and there was a thread about the article, but you guys said it wasn't up.
That's part of the content that's still pending being transferred and converted from the old site. I actually submitted that particular article to DDR Freak. It can be found here: http://www.ddrfreak.com/library/contrib ... ID=7909984
It should be available here in a more usable form again as well. Either way, I'm glad you're finding the information useful.
I found that article VERY helpful back when I first read it last summer. Especially since I got a job at the arcade I play at; it's let me maintain the pads as best I can so everyone benefits from it.
