According to Woodcraft Magazine, Whiteside now make solid carbide spiral-upcut bits in metric sizes suitable for use with dominoes. Router owners who want to use dominoes for floating-tenon joinery can now do so. They can achieve similar accuracy in routing mortices to that of a Domino machine, if they build one or other of the morticing jigs for which free plans can be downloaded from my blog, see below. Probably after a time many will want to go the extra mile and eventually buy a Domino.
