first up is a toggle clamp i bolted to some 10mm plate after drilling and tapping center of plate to accept m10 stud.
its used on drill press when doing batches of same thing.
second up is tapping aid for use on drill press.
its basically a collar that fits on chuck under toothed section one handl is fixed other is removable with pin that fits in hole thatchuck key fits into.
allows for easier tapping when doing batch work.
just make sure drill is unplugged so if you leave it someone cant switch it on
