I'd like to report that the RO 90 can be useful for powered hand-sanding of small parts.
I am working on four ash brackets for a desk I am building. The parts are 11 cm x 3 cm x 2.5 cm - the perfect size for a clamp that has four fingers and a thumb. They have some flat surfaces, some concave surfaces, and some convex surfaces. Existing imperfections include saw marks and some router burn. Included, I should say.
To sand the parts, I turned the RO 90 speed to the lowest setting, and turned my CT MIDI speed up to maximum. I also found and put on a leather work glove. I held the part in one hand and the RO 90 in the other. In the random orbit mode, a light touch didn't trigger the head rotation, so there was just the swirling motion. With more pressure, head rotation kicked in, but at the low RO 90 speed it didn't grab the parts at all. (Safety first!) The face of the head was able to do a good job sanding the flat and convex sections of the parts, and the edge of the head was able to reach into the concave sections.
Best of all, the dust that was produced vanished into the CT MIDI right away.
So far I have only done Granat 120 using the standard pad, but the technique is looking promising for the rest of the finish sanding for these parts.
