.. getting into pic#1 about the Brush needed .I you look closely you`ll see that some of my parts have Black Crud on them..That`s due to me Thinking I had a Wooden Handle brush, of the correct type bristle at home, and realizing WRONG-O.It was a plastic handle.I didn`t contaminate the Welding area, so the Welds are fine.A wooden handle is best,a Tooth-Brush profile ,is probably the most appropriate for Hobby work..So step 1, of the instructions in the pic is where we are at. I don`t have pics of me actually doing it because I would need a 3`rd hand..
