Even though I reduced the dimple die of the female part of the 3/32" dimple die the part left smiley faces on the curve of the side skins. I only did one and then stopped to order a new one. Big cost to replace the skin but I would have hated seeing those smiley faces on the skins. I ordered a new reduced die from Aircraft Tool Supply and the new skin arrived yesterday. I will practice on the replaced skin until I am ready to do the new one (with no smiley face).
