A customer wanted his rear cylinder notched to follow the shape of his pipes, so Aad & Johan Heemskerk came up with an "interesting" way to do this without removing the engine from the frame, let alone taking the engine apart.


They created an improvised jig on the frame to guide the sanding role exactly concentric with the pipe. Aad even filmed the whole thing!
