Have we ever shown you a chase before? Ours is an original off our press - circa 1893. Inside you lock up a base with bits of timber and metal furniture, pop in some quoins and tighten it all up with a quoin key. I love this process, so old and beautiful, and reminds me all just a little bit of tetris. It must be strong and solid to withstand the turning and churning of the press.
Oh and we don't recommend every dropping a chase, especially near your toes... we did once, it wasn't pretty.
