as hobbyist i need mill for steel
by reading forum posts rf45 or zx7045 or mb4 or bf45 .....
look like great tool to have for most of my needs
but problem is when i need to work on tinny parts for my scale models
all advise high rpm for these up to 6mm mills & lowest 0.1mm ones
this machine got max 3000rpm so i need advice & help

i read that some ppl put side mount for high rpm spindle but on small machines
like bf16/20 size with small head
is it possible to do same with rf45 size and big head to add 1.5kw water cooled spindle (like ppl use on wood routers) on side for time when i need to work on tinnnny parts and remove when i dont ?
and how if it's possible ?
or just to lower size of machine to smaller head like sx2/3 or like ,and thinker from there ?
thanks
sorry for grammar errors
