Please call to discuss depth depending on etching method. We can supply the DXF file for this. ] Edge and top finish are most crucial here, these are the most visible parts on the clock, every measure should be taken to be sure they are not scratched or bent. Parts should be flat to within .010". The locater pins underneath should be same material as plate. They can be located by spot facing blind holes from the bottom, pressed in and then loctited in place. Most important is that there is no discoloration or show through to front. They take almost no lateral load and are primarily for location. 74 75 76 77 78 79 16 80 15 81 14 82 13 83 12 84 11 85 10 86 09 87 Matl: Stainless Steel Qty: 2 required 08 88 07 89 06 90 05 91 04 92 03 94 93 nm: Year.VLM 02 01 00 99 98 97 96 95 sc: 1:3.5 dt: 10/22/98 p#: 5507.2 The Long Now Foundation tol. +/- .020 (etch) +/-.005 (locator pins)
