Has anyone got a link to a reference website that discusses 'all things workshop'/ a workshop guide. i.e. one that gives information on what files you use for what jobs, what grinding discs are used for what purposes, drill speeds for various metal types, safe use of bench grinders, etc, etc......you know the stuff??

do not know a website but here is a starter

if it moves do not touch.
if it smokes do not touch.
if it smells do not drink
files usefull for paper work for registration.
metal grinding discs for metal
concrete grinding discs for concrete.
bigger the drill bit lower speed.
do not look away when grinding.

see know my stuff.
