Well, mini-mill.
I don't have an SG and don't have space for it either :) I do have a mini-mill and a magnetic chuck.
Is it possible to acquire:
- one of those sharpening holders + whatever adapters required to hold various end mills
- flaring cup grinding wheel + adapter
The chuck goes onto mill's table, endmill into sleeve and into the holder, grinding wheel gets mounted onto the spindle, rpms get cranked up and ... will it work ?
