Cut Along Dotted Line
I have decided, for the time being, to offer to cut out portafilters for my friends and family. It is quite expensive to buy the pre cut ones, and there is usually a good charge for having someone do it in a metal shop on a lathe. So I’m doing it, for the time being, for the shear joy of shaping metal. I found a hole saw and a file quite sufficient for the job. With a hand held drill, some steady hand holding, (here is the hard part) and a little finesse with a Bastard file, a fine looking finished edge can be achieved.
