Update!
Karen from Moto Lita has offered to have her machine shop drill to 14.94mm and cut the internal 29 spline, all for £50, being already tooled up to to the job they just need an undrilled steering column half from Optimill, so I've asked Optimill if they'd be prepared to sell me a half hub that has yet to be drilled and splined?
In an ideal world this would be the prefferable approach, so I've got my fingers crossed Optimill will sell me the partially machined part?
