If the makita was still under warrantee, I would return it and keep my mouth shut. Collect a new one for free and fabricate an upright on the jig that would be small enough to get your hand around to hold the grinder in place with your hands. You can use ball bungy cords to help hold it in place, these bungys will not put undo stress on the rotating internals.
Some of us have a thing called integrity, and thus wouldn't feel right stealing from a company. Don't for a second think that lying on a warranty claim isn't stealing. It is.
