[ARC5] BC-221-D, tool needed to undo knobs

[Roy Morgan]

Yes Bristol spline wrench is the right tool. Flat sided hex tools are Allen wrenches not Bristol spline wrenches. Very different. Put liquid wrench onto each screw until you can get the RIGHT tool 
Tonight I can report the correct size of tool in detail. 

Roy sends.
