IronDragon, thank you! Been scanning IFI for a while. Good to be on an active forum with knowledgeable craftsfolk!
I have cinched the jaws completely closed and tried to crank on it, and no movement at all. Seems super solid. Just some cosmetic inconsistencies that do not seem to persist deeper in the weld. You can faintly make out the shape of the piece around the sides and back where the welds are completely synonymous with the arm below.
I greatly appreciate your feedback, and in either case, it seems that it is of non issue (:
Awesome to hear linseed will work!
Any input on wire brushing and if that would do more damage than good? A friend of mine may have a powered wire brush though...I will have to check on that!
