I have been asked about the track gauges I make for myself often enough that I decided to make a video of them for you guys.
I used my camera to do this so the video is only so-so. The link to the video is on my website. Scroll down to todays date of “Wednesday October 15th 2008” to find it.
Enjoy and have fun making lots of track gauges 
If anyone has a camcorder they can spare I would be happy to make better videos for my free tutorials
