Review on Drilling Installation Professional Measuring Woodworking Stainless by Warren Hess

It was a great tool until one of the lag screws came loose and I had to improvise with strips of tape making fine adjustment difficult. I'll admit that I may have overtightened the set screw and am willing to buy an extra part. I emailed the seller and he offered to ship the item. That was a month ago, still waiting... So while I'm giving it four stars...admittedly it's a five star tool...be careful with the set screws. Okay, I got the part for free and it's back in business. Now I will be careful when tightening the set screw. This tool is extremely accurate and easy to use. worth the money.
