In hopes of receiving information with regards to minimising the chance of general injury i was wondering wether somebody has any advice on the safe construction of legal homemade slam-fire shotguns. My main worries relate to barrel blowout and schrapnel injury - potentially leading to loss of hands, fingers or other body parts.
The project in mind consists out of the usual 3/4 barrel pipe, 1'' inch receiver and 1'' inch breech cap with a firing pin glued into it. The barrel might be sanded down with 60 grit sandpaper to make it slide in and out of the receiver smoothly. A metal stock will be welded on to the breech cap (or a wooden stock will be made that holds the breech cap) to make it comply with the length requirements for the weapon to be legal. Handles might be welded on to the receiver and barrel for grip. My questions are as follows;

Handles might be welded on to the receiver and barrel for grip. My questions are as follows;
- How many times can a sanded-down 3/4 barrel be shot before it becomes unsafe?
- Will loose fitting shotgun shells become a potential hazard?
- What type of protection will effectively shield the fingers, hands and arms from barrel blowout?
- Are there any other important factors to be considered to maximise personal safety?
