Good day everyone,

I was wondering if the ER11 spindle upgrade on a Proxxon MF70 is a direct drop-in upgrade? or does all of the kits required re-boring holes, retro-fitting and etc.. ?

I have seen some really cool upgrades done to it, including brushless motors, belt drives etc..
but ATM I was thinking only about replacing the stock spindle to a slightly more solid ER11 type and keep using the stock motor, not sure however if this is an easy mod?

Any input would be much appreciated.
