I’ve purchased some real G10 material to practice on. What I wanted to practice was:-<\/p>\n

    \n
  1. Learning how to cut it well (even though this isn’t required for this build)<\/li>\n
  2. How to sand the Leading and Trailing edges to the profiles I’ve decided.<\/li>\n
  3. Sand the root and tang to Grit 80. Also sand other edges lightly with Grit 80 to remove any burs. (But I don’t want to change the shape)<\/li>\n
  4. Sanding back with Grit 240 to give it a good finish for painting. I sand it ALL over, except on the tang, and the root where it is glued on the motor mount<\/li>\n
  5. \u00a0Score the root of the fin (yes, on the thin edge) using a punch and a bit of elbow grease. Did this every cm, in both directions at 45 degrees<\/li>\n
  6. Score Tang of Fin that is going to be below the air-frame. I did this every 2cm at 45 degrees in both directions<\/li>\n
  7. Cleaning the surfaces thoroughly with Methylated\u00a0Spirits<\/li>\n
  8. Inspect the fins to make sure there is no other dust, grime or dirt.<\/li>\n
  9. Perform the following preparation steps<\/li>\n
  10. Attaching to “motor-mount”<\/li>\n
  11. Test paints – to see how finish is.<\/li>\n<\/ol>\n

    Preparations Steps<\/h3>\n

    Before I can begin attaching fin, I need to prepare my work area. The “main” steps are:-<\/p>\n
