Bought my wife a Bauer scroll saw to see if she was really interested in scrolling before investing in a better saw.These thumb screws fit perfectly and are a huge update to the stock parts. Stock parts do not rotate at the tip like these do and they bend the blades.Replaced with these and bent blades are no longer an issue.That Bauer scroll saw is a very good machine for a beginner who wants to get started in the hobby.One day we will upgrade the saw but for now, with the addition of these thumb screws itâs a great machine!
