[CAD_CAM_EDM_DRO] Re: Creating long straight edges

If you are developing a flat surface for mounting linear rails you should
consider the pad and grout method as it is less work than scraping a
continuous surface. Scraping guru Michael Morgan explained this one to me
last year.

In this process, shim stock is epoxied to the surface at intervals, some
multiple of the length of your precision level. Alternatively, they may
need to be placed so as to coincide with bolt locations on the rail. These
are scraped in using the integrating method Les described.

When you are satisfied with the flatness, epoxy grout is trowelled over the
entire surface, the rail is coated with release agent and bolted in place.
In addition to being less work this provides constrained layer damping for
the rails.

There are several variations on this method, one of which I believe Les used
on his gantry (Les?).
