- Apr 7 9:57 PMHello Dave.Agree that the gibs need to be flat,but not lapped unless you intend to finish the joband scrape both surfaces both gib and running edge of the machined vee.If not they will tend to "RING" (stick) together as similar to a slip gauges,and also you have no areas or pockets for the oilto be trapped between the surfaces for lubrication.Ideal material is not brass but phosphor bronze and or cast iron because of the materials inherent lubricitycontent and durability.I worked for many years building thread grinders and jig borers,this was how it was done as follows.The machine beds (cast iron ) were first milled after 2 years outside weathering,then all surfacesincluding the vees were surface ground and finally scraped to there mating running parts.JohnSpain.On Monday, April 7, 2014 10:10 PM, "davegreenham@..." <davegreenham@...> wrote:
