note:.Pie shaped opening are for aesthetic improvement and weight reduction. Tolerances here are not as critical. They have 1.5" wide spokes with 1" distance from both internal and outter diameters. Their internal corners are radiused to .25". tol. +/-.005 Matl: 70-75 Al Qty: 2 required nm: ReteSubSpacer.VLM sc: 1:3.5 dt: 11/11/98 The Long Now Foundation p#: 5514.2
note: I assume that a multi axis wire EDM is the tool for cutting this. We can supply the DXF or IGES file for this. The inital cup shape could be spun or turned but should be sanded smooth to remove all machining marks. (to 800 grit) It could even be welded from two pieces if necessary and the welding ground and sanded out. This part can be made from aluminum if necessary but we would prefer stainless. Grade is only important in considering finish. We want to electropolish it to a high luster. sc: 1:3 nm: Rete.VLM dt: 10/22/98 p#: 5501.2 The Long Now Foundation tol. +/- .020 (shape) +/-.005 (pin holes) Matl: Stainless Steel Qty: 2 required
