Great inspiration. Couldn't find you mentioning what kind of welding equipment you have used, have you used MIG MAG all the way? If so are you using .6 mm or .8 wire? Have you used welding primer or have you cleaned the welding areas for paint before welding? How did you weld in the front part to the front wings, is it possible to do the normal MIG/MAG spot welds with a 6 mm hole drilled in one of the parts?
