Re: Fabricating Aluminum Sprockets

For aluminum, it's important to have a really good cutter on your table. I assume it's PlasmaCam, or a knockoff. Our lab got one last year, and I was very excited to be able to cut out parts in house. However, this was not the case because the cutter was not of excellent quality, and while cutting Al, it just melted out of the cut path. A shop in town actually uses a special gas or gas mixture to facilitate plasma cut on aluminum.
