Good reference book! Lots of good information, was a little more complicated than I hoped it would be but after trying the examples the author gives it becomes much easer,

This jig is amazing. I used to build a picnic bench style table. The ease of use and accuracy is outstanding. All in all, I probably drilled at least 50 holes with this chick just for that one table. It made the job so much easier.

I bought this at the recommendation of someone to help my psoriasis. Although I haven't seen the benefits to my scalp psoriasis yet, it has already cleared my elbows. I am very happy with this product!
