I am sorry about not following up on this subject, but, have had a bout with colon cancer and am now home from hospital recovering. All went well and the surgon feels he got all the bad cancer removed and the path report looked good. I give all this good report to the love of God and the power of prayer. So, I have not been at my saw for a few weeks, but, will get back shortly and test the blades on the mdf.
