Sandcylinder Lathe M33x3.5

A sanding cylinder (drum sander) for European lathes with an M33×3.5 spindle thread — a size that's surprisingly hard to find off the shelf, so I designed my own.

Design details

The cylinder is designed to use 12 cm sandpaper strips, which is a standard size that's easy to source. You can choose whatever grit works best for your project.

A few thoughtful features built into the design:

• Circumference ruler included — makes it easy to cut your sandpaper to exactly the right length without guessing
• Double-sided tape gap — there's a recess around the cylinder sized to fit standard double-sided tape, so the sandpaper adheres cleanly and stays put
• No raised edges or seams — because of the tape recess, the surface stays flush with no bumps or peaks that could cause vibrations during use
