Abrasives and Sanding, with the fine and gritty Noel Green
‘use the sandpaper like someone else is paying for it’ SANDING -A WOODWORKING ESSENTIAL.
Aluminum oxide or garnet or silicon dioxide glued onto a backing. Acutting tool like a chisel or saw. 3M ceramic is a newer product. Quality matters.
GRIT – a number referring to the # of particles that are fit into a square inch: two systems, USA and European.
Types: sheets, discs, belts, mesh, random orbital, other.dimple discs

Turner’s mesh (abranet), mandrel and disc inserts.
Best type depends on the use and the user. Some types can be friable – grit wears off leaving a new layer. Organization matters.
Inertial sanding tool for less aggressive sanding, polishing to a shine.
Mark the grit # on back of all so that when you drop a piece or forget…
European grits are prefixed with a ‘P’. 180 = P180, but all others are different! Be nice to you – use either USA OR European grits, don’t mix em.
5 rules:
1. keep it sharp and clean. Clean with crepe, start each project with new paper
2. refine the shape and remove all tool damage before moving to next grit. Next grit is only to remove previous grit’s scratch pattern. If turning, consider tool repair, sanding in reverse or with lathe stopped
3. Sand through progressively finer grits without skipping any of them. Rule of 1.5 says to go from one grit to 1.5 times that and continue likewise. Use air to blow off dust and particles.
4. remove all dust and grit between
5.Slow is GOOD, Slower is better – heat is the enemy. Sand cool – slower lathe speed, slower movement, less pressure…slow drill speed. If lathe turning in reverse, ensure chuck is secure and power sand in reverse also
Sanding pads, like scotchbrite pads (3M, SIA) can be good for polishing. Various pastes and polishes for finer finishing. 0000 Steel wool can be used. Toothpaste can be used to polish finished pieces.
Flatwork tips. Turning tips. Sanding Safety_ use a mask!, dust collector, can use wet sanding with water (on acrylics) or oil (on woods) to minimize airborne dust. Walnut dust is toxic!
More sanding tips! Prepare packets, make a static sanding pad on a disc for the lathe. Make specialized sanding pads for curves and special surfaces.
Sanding and finishing is crucial to finished product – take the time!
