I'm having to make a set of curved '54 only Harley-Davidson tank emblems from a set of straight "one size fits none" re-pop emblems. The base plates come with a self-adhesive backing. I might expose some of the adhesive for placement, but I will want to braze the base plates on a set of new re-pop '49 (tank shift) tanks. I have an Eastwood trim hammer and a small horned anvil. Where do I start?
