Need feedback on my first How-To video

I can't think of a better group of experts to beat me up.

I posted a video showing how I make a drilling guide, to drill into a rounded object - in this case it's a funny car frame.  I'd like to know if it's presented in a manner that you could actually make it.  Also, is it something that would be beneficial to you?

I plan on more videos and I'll use your comments to make them as useful and quality as possible.
