I am designing a large floor-mounted cabinet.
Having recently assembled two large IKEA wardrobes using their cam lock system.
It was far more successful than I thought it might turn out that I plan to use the same method. Screwfix sell 15mm Hafele cam locks and the cam dowels to which they are attached.
What I cannot find is any information concerning jigs, appropriate drill bits or advice to ensure that tackling this does not become a hit-and-miss affair.
