hy jreynolds, please, can you develop a bit about inner working of the adaptive bushing, the double contact that you did no like? i have never had the ocasion to inspect the inner mechanismWe found that the double contact of the adaptive guide bushing was causing any differences in od to multiply and make the part deflect
indeed, as being more complicated than the regular guide bush, may be less consistent when you really need that 'extra' precision
those holes where intersecting, thus locating at same z ? do you have a part drawing, please, i wish to understand better your caseThis part has 2 cross holes thru it with a tight true position
ps : i just found this, don't know how relevant it is
