Model Engine Review - Enjomor Whippet

The texture of casting might be imparted by etching or shot blasting. Blast might edge out for appearance, it'll blend every tool mark evenly. There might be a way to texture paint or add a 'contaminant' instead. But they are beautiful raw.
When I needed a super finish on narrow surfaces, the trick was stoning one flute off a two flute end mill, making it a fly cutter, but makes clean corners tedious.

thanks, I did tumble them in ceramic beads for a few hours, but this probably needed to run for hours and I got fed up of the noise in the workshop...

The modified two flute mill is a good tip, will have a go, Thanks, Nigel
