I ordered the following from Avery today:
Part # 3753 – 6″ Scotchbrite cutting and polishing wheel
Part # SB280 – Perma-grit Sanding Block – Flat – 280mm x 51mm course/fine
I only make a special entry for these because they come so highly recommended. An F1 Rocket builder said he wouldn’t build again without his Permagrit block, and another RV-8 builder really convinced me yesterday that I am not going to get the edge finishing final product that I want with a scotchbrite wheel. I’ll add pics when they show up.
