Re: Precise holes for bearing -> what endmill for aluminium?
i needed some 13mm holes for bearings....
my method was really dodgy, but not exactly quick...
roughed out to 12.7 with what i had.
waited 3 months (who knows what happened? the ship sunk?) for a 13mm endmill from fleabay. i waited 2 months, ordered another one, got a refund on the first one...and then they both arrived on the same day!!!!
plunged that straight in.
never measured them but heating to about 70 degrees C made for a perfect slide in fit...
it was quick once i had the tool
bigger sizes, id use a micro boring head myself, but hey...
with so much stuff on hand, one spends more time locating it rather than using it.
