Handlebars are brass rod, used a small vice and pliers to bend. matalic paint on some parts. Same with exhaust pipes.  Mufflers are maple with foil wrap.  Mark bend locations with a marker. it's a trial and error process and hard to visualize sometimes.  Used a foil bonded to maple for "chrome" parts.  Used hobby wire for wheels and other trim.  Seat is ebony. Handle grips are dowel drilled to insert handlebar - precise process!!
