angle magnetic clamps

i needed a angle clamp to hold plastic together at any angle while glue drys. this was the result. it uses 4 20x10x2mm rare earth magnets epoxy glued into the arms and 2 m8 nuts and bolts to connect the arms togeather. there is enough of a gap that a glue brush can get into the join while clamped. i also put in locating notches in the pivot point to easily find 90 and 45 deg angles.
