Well folks, the man himself has answered in an email... So here are his own words!

Well son, where do I begin??
I didn't expect to see my little project for you on the web, but there it is..... I'm overwhelmed by the comments. I would have done better if I knew you were going to do that.
I think by the comments, you may have sparked some interest in people trying to make their own, which is great. I would love to see some of the results .
Now, before you ask, no, I'm not in the business of making items for sale. My response to those that asked is " If you want one, make it!!"
Not sure if I should thank you, or cuss you out for doing that, but pass along my gratefulness, for all the nice comments.

Dad
