This is a replacement/improved upper blade guide for the model 113.244513 Sears Craftsman Bandsaw. The original guides used metal plugs to hold the blade in place along the path, but my improved design uses skateboard bearings for the blade guides and thrust bearing. You will need to keep two of the screws from the original blade guide to hold 10 mm hex rod to the blade guide. Also, you will need about 8 inches of 10 mm hex rod, a long m6 bolt, two shorter m6 bolts, the washers and nuts to go with them, and 3-5 skateboard bearings. How everything needs to attach should be obvious from the picture, but if not leave a comment and I can try to make some instructions.
