One of the most intractable problem faced by owners of both small and large machine tools is re-grinding lathe beds and restoring worn slideways. Of particular difficulty is anything connected with the compound slide rest where tolerances are tight and alignment, on the relatively sort travels, difficult to get right. Although it's possible to learn how to hand scrape these (and beds and saddles) back to perfection, it is a far-from-easy task and really best left to an experienced professional with the right equipment. Today the leading exponent in this field (and very experienced in the restoration of Schaublin components) is Brian Caddy in Nuneaton. Visit his web site: slidewayservices.co.uk
