# CAD Spec — Precision Mounting Block **Origin**: top-left of front face. X = width, Y = top→bottom, Z = thickness. ## Stock - Width: 0.625" | Length: 1.654" | Thickness: 0.472" (+0.002/+0.001), split into two 0.236" (−0.001/−0.002) steps ## Left edge - 0.250" wide land (+0.003/+0.001), from left edge — ties to notch feature - Precision bore centerline: 0.125" from left edge ## Holes (Y from top) | Y | Feature | Dia | |---|---|---| | 0.156" | Precision reamed bore | Ø0.0938" K7 (0.0934–0.0938") | | 0.378" | Through hole | Ø0.15625" (5/32") | | 0.503" | Through hole(s), TYP — **spacing unclear** | Ø0.0625" (1/16") | | 0.768" | Through hole — **dia not legible, need confirm** | ? | | 1.437" | Through hole(s), "2x" — **1 or 2 holes unclear** | Ø0.21875" (7/32") | ## Section A-A (dowel bore detail) Stepped bore: reamed Ø0.0938" K7 section → reduces to Ø0.0625", with 1/64"×45° chamfer. Depth callouts: 0.329", 0.734", 0.984", 0.236" (−0.001/−0.002), 1.470". Position tol: ⌀0.005" to datum A. ## Notch/rail (isometric views) Step cut along one long edge, ~0.250" × 0.236" — **least certain feature, geometry not fully resolvable from the image**.
