[QUOTE="Bug, post: 150474, member: 3940"] Since I went with a copper theme in customizing my bike, I have wanted to make copper downtubes for the stock carbs. I just hadn't been able to figure a good way to connect copper plumbing to the heads. Frustrations with the stock carbs had me considering a single carb and then I found inspiration here: [url]https://classicgoldwings.com/forum/viewtopic.php?p=137161#p137161[/url] Special thanks to Canukxxxx! So here starts my single carb journey... I hit up the local metal recycling yard and found these materials just begging to be brought back to life. I bet they didn't quite have this in mind... [GALLERY=media, 26522][/GALLERY] 1' x 2' piece of brass sheet, (for other projects) 4" piping with a cap for the plenum, various pieces of 1" pipe with 90* elbows for the runners and downtubes roughly 5' piece of 1" pipe, and the best piece, a 4" x ~16" piece of 1/4" copper plate with holes that fit the pipes. To be used as flanges and, if I have enough, to mount the carb. Canukxxxx said the doughnuts would be easy to make from the plate, if I had some hole saws and a drill press. Well, I had neither. I convinced the wife to let me get the hole saws but the press was a bit too much. I screwed a piece of aluminum plate to my trailer bed, bolted and clamped the copper to it, and started drill/sawing. I cut a grove for the o-rings, then cut out the doughnut. I smoothed the o-ring grooves with a dremmel, and sanded away until pretty and shiny.
