Rick is not only knowledgeable, but a great, friendly and funny person. He has worked tirelessly to promote scroll sawing and woodworking and I have know him personally for almost 15 years. His site is great and if you can't find the answer there, you can email him and be assured he will get back to you with the information you need - and then some. Thanks for pointing out his great site. I am sure lots will benefit from visiting it.
