Welcome to the message board
Perhaps the Lowes web site can provide better information than their local employees.
You can also find demonstration videos on dremel.com here is the link:Dremel Project Videos
Also have a look at the non-video items in the Projects & Community section of this site. The link to this section is at the top of the page.
As you may have noticed, you are the first to start a thread in the Pinewood Derby section of the board. This and a few other sections were recently added. It was only by accident that I discovered them. The point is that the other regulars may not have discovered these new sections yet so please be patient. In the mean time I will send a PM to a member I know to be involved with Pinewood Derby projects.
