I saw an Austrian turner at the Toolpost Open House today (can't for the life of me remember her name) but she had made a sanding block out of polystyrene, hollowed the middle out and put holes in the base, attached self adhesive Velcro to the base (where there weren't holes) to which she fixed Abranet. She then used a camvac hose through a hole in one end and hey presto, no dust.
She sands at low speed and simply shakes the dust off the Abranet when she takes it off the block as she goes through the grades - quite an ingenious homer, and almost free!
I use Abranet a fair bit and find it lasts well, as long as you sand at low speed (I tend to sand at about 850rpm) and keep moving over the surface with even pressure.
