Watch this video to see me demonstrate how easy it is to change both pinned and plain end (pinless) blades on the WEN scroll saw model 3920. Thanks to my friend Andy who recommended I make a video on this topic. This is a great introductory video for WEN scroll saw owners, beginner scroll hobbyists, and DIYers.
