Osnova (Base) Part Blueprint - Steel 40Kh GOST 4543-71 Drawing, Niva-FAQ

This is a Russian-language engineering blueprint (A4 format, scale 1:1) for a machined part named "Основа" (Base/Foundation), sourced from the website WWW.NIVA-FAQ.MSK.RU. The part is to be made from Steel 40Х (40Kh) per GOST 4543-71. Two orthographic views plus an end view are shown with full dimensioning. Overall length is 153 mm, with segment dimensions 17.5, 58, and 77.5 mm; widths of 18 and 24 mm; heights of 23.5, 15.5, and 4 mm. The part features a large hole of ø17 with a ø19 counterbore noted as "с одной стороны глубиной 1,3" (on one side, depth 1.3 mm), located 44 mm from one end, and a ø12 hole with tolerance +0.05/-0.10 located near the other end (109/99 mm dimensions, 10 mm offsets, 20 mm from edge features). The title block lists Иванов Ю. as the designer (Разраб.) and Дедюхин А. as copyist (Копировал), 1 sheet of 1. This drawing appears to be a fabrication template for a homemade tool or bracket documented in the Niva FAQ community; a searcher can obtain all dimensions and material specification needed to manufacture the part.
