I really like the concept of the Rockler Cookie Plus kit, but it seems it is only available for 3/4" holes. There are some knock-off copies available (which I wouldn't want to support) but they are 3/4" too.
Does anyone know of 20mm cookies? Would help if they are available in the UK, but I'll pay shipping for the right product.
I've tried using some heat shrink on 3/4" pegs, but they end up being 20.5mm or so.
