Simple query, but interested to hear opinions. I only have a modest sized bench lathe with vertical table available for light milling. It works fine within its capabilities.
I'm just nearing the end of building Harold Halls' basic tool grinding table (as described in his book), and have a couple of 6mm dia slots to do in 5mm thick steel.
Just wondered if it was a) worthwhile b) quicker c) less wearing on cutters to: Chain drill and saw out the bulk first (eg to around 5mm) then mill with me 6mm cutter, or just to go straight to milling starting with a
5.5 and finishing with a 6 (which is the way I did it for a similar slot in the main table)These 2 slots are in fact only for sliding adjustment of the mounts so are not critical - accuracy wise.
Any useful thoughts greatly appreciated regards Mike
