The Straight Story: Part Two
After determining a baseline on the flowbench and coming up with a viable porting plan, Alaniz begins the porting regimen by choosing the correct burr. Cutters tend to clog up with aluminum, but the wide grooves on the coarse burr can minimize clogging. For a finer finish before polishing, a double-cut burr is utilized. It also requires a lot of lube. The other burrs on the left are used for getting into hard to reach places.
One other point on porting: since air must always be moving - and where it's not, you have to force it - sometimes the implementation of a venturi is required. This essentially means that some material must either be added (by welding) or removed to help facilitate movement. View Related Article
