Best wayto avoid sanding: • Sharp tools • Good tool technique
Sandpaper is a cutting tool Not a shapingtool –Don’t oversand
Sanding is meant to get rid of tool marksTry to sand ridgesNot tear out
Do Not Use Cheap Sandpaper - mixed grit 80 in 240 (CAMI,FEPA, JIS, Micron) • Friability (fresh edges) • Velcro bad • Won’t stick to pad • Separates from grit backing
Use the largest sanding pad that is practical • Faster • Removes ripples Clean bowl between grits
High Speed Sanding Advantages 1.Cuts sanding time dramaticallyf 2. Does NOT obliterate detail (perfectly centered) 3. No starved horse 4. Smoother finish (feels like next grit up)
Concerns Heat, cracking of wood - Pressure - Speed Ease up on the pressure (Grand Canyons)
Speeds Lathe: 500-1200 rpm Power Sander: 6000 rpm Speed or resistance allows grit to fracture – not heat Alox is friable Speed also helps cool wood and disk (if pressure is kept down)
