Its all good, I spent some time building a work holder for this type of work for sanding and welding



these are the 3 sizes, the one on the far right is the first pattern, it was built at 3% larger scale and roughed in the shape, the middle one is the first real casting and then adjustments were made to the weight and shape for casting drafts and expected shrinkage, then the final pattern is built on the left, it is the result of all the other work


This is the final pattern, its built with no primer or body filler , its all aluminum so adjustments can be done after testing the first castings in the brigeport
