In this DIY video project Maker B shows us a cool hand made project where he turns a couple of bolts into a miniature portable mini safe. This DIY build doesn’t get all its material from a single bolt, it’s more like two bolts and a few odd pieces of brass, but that doesn’t detract from the final product one bit.

Maker B relieves the two chunky stainless steel bolts of their hex heads and their threads on the lathe, forming two nesting cylinders with a satisfyingly tight fit. Whatch the video: “This is how I made a portable mini safe from stainless steel bolts.”
A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams, by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an electronic or mechanical keypad./wikipedia
Each disc is stamped around its circumference with the 26 letters of the alphabet; we thought the jig used for stamping was exceptionally clever.The combination, which is set by placing a pin next to a letter in each disc, protects the admittedly limited contents of the tiny safe, but functionality is hardly the point. This is all about craftsmanship and machining skills.
