Re: [CAD_CAM_EDM_DRO] Re: Scraping

Hi Chris,

Why not make it as two separate bits. That is, mill the dovetail sides on a
metal plate and then, after finishing it, bolt it onto a flat metal
backplate. That way its much easier to adjust the dovetails to size as you
can see what you are doing on the bench and you can then easily align the
head before finally fitting steady pins and screwing it in place (with
threadlock)
