Hello, These wood handlebars are peeking my interest... I was wondering how they made them... I know they where bent by steam but how did they get the shape? What sort of jig/jigs were used and did they do the bends in one sitting or do a few steam bends and move them from one jig to another between steaming? From searching looks like they where made from hickory... any other woods used? anyone have pictures of these jigs? Thanks in advance!
