The last time I was there it took ages before someone came up with the name
of the machining process for the step and repeat chiselling for forming
those large aluminium heatsinks, found on domestic amps of the 80s, with
those distinctive curved fins, - its called skyving.


So? Its not something done in a home metalworking shop, but knurling
is. Of course you would have to actually do something right, for a
change. Some of the guys on there make things that would blow your
mind, when it comes to custom tools.
