This is particularly effective when used in combination with a 'chain' of drill holes to quickly remove an opening marked on the STEN receiver. Fitted with a 'reinforced cutting disc' it becomes a mini angle grinder, ideal for cutting out and grinding openings in pieces of tube quickly and neatly without having to manually use a hand file. Inexpensive arc welders are available for purchase over the Internet:Ī rotary tool or Dremel is highly useful for delicate grinding and cutting operations. This is a relatively quick process and with care can produce a bolt just as good as a factory made original. It's most useful application for this project is to cut and grind the bolt to it's required profile. Fitted with a 2mm disc it can be used to easily 'sculpt' thick steel into any shape in a fraction of the time it takes to manually use a hand file. Rather than tediously using a hacksaw to cut steel sheet, an angle grinder fitted with a 1mm slitting disc will accurately cut a straight line through steel of any thickness in mere seconds. Using a cheap angle grinder the average hobbyist has the ability to perform speedy removal of steel using a variety of cutting and grinding discs. (Non-functioning dummy barrel present on display model)Ī few very basic and inexpensive power tools can be used to simulate machining actions usually reserved for a milling machine. (Disassembled: Back plug, recoil spring, bolt, magazine, sear and trigger displayed) This document is for academic study purposes only. It's bolt is also inert with no firing pin. It's dummy barrel consists of a hardened steel spike welded and pinned in place at the chamber end and a separate solid front portion protruding from the barrel shroud for display.

Using the simple techniques described, the need for a milling machine or lathe is eliminated making it ideal for production in the home environment with very limited tools.įor obvious legal reasons, the demonstration example pictured was built as a non-firing display replica. The main differences however include the number of components having been greatly reduced and it's overall construction made even cruder. The DIY STEN Gun is a simplified 1:1 copy of the British STEN MKIII submachine gun.
