Amana 61293 Sanding Drum is designed specifically for template-based sanding on a router/shaper using a rub collar with ball bearing. Here's everything you need to know: 🛠️ Key Specifications Diameter: 60 mm (2 3/8″) Cutting/Sanding Height: 100 mm (4″) (some sources say 76 mm, but most list 100 mm) Bore Size: 1¼″, fitting standard shaper or router spindles Recommended Speed: Up to ~4,500 RPM 🎯 Primary Use Ideal for smoothing and shaping rough workpieces using a bottom template and ball-bearing rub collar, which guides the drum along the template edge for uniform sanding . 🔧 Accessories & Replacements Optional Rub Collar: Amana part 61596, fits the 61293 drum and ensures smooth guidance. Replacement Abrasive Sleeve: Part AB61293, a medium-grit P80 sleeve designed to fit the 100 mm drum. 💡 Usage Tips Loading the Sleeve: These sleeves typically slide over the drum and are secured with adhesive or a backing. Some users find it slightly fiddly but manageable. Using with Rub Collar: Attach the collar to the top/bottom of the drum setup. When mounted on the shaper/router, the bearing runs against the template edge while the abrasive surface mills the workpiece to the desired geometry. Safe Operating Speed: Maintain around 4,500 RPM to match tool specs and ensure even sanding—going too fast risks excessive heat or uneven wear.
