What welding projects are you working on? Are you proud of something you built?
How about posting some pics so other welders can get some ideas?

Yamaha RD 500 custom pipes

Postby KVAS » Sun May 15, 2016 6:40 am

Hi guys, another two stroke project from me. I build these pipes during the summer in 2015. They were a total nigthmare to build as the upper pipes has to intersect to fit the beautiful Akrapovič silencers at the end. Everything is packed so tight They are made from 0.8mm thick cold rolled steel. Everything was done by hand, including cutting and rolling the sheet metal. It was absolutely one of the most difficult projects I have done. Here are some pictures.

The geometry itself is copied from jolly moto, as I had no experience in calculation of exhast for 125cc. Shape and curves were all done by me, I help myself with a model made from a steel wire.
