I spend 4-6 hours a day during the week building suppressors, 22 pistols and/or AK's . I build other stuff too and do customer custom work. By day Im a mechanical engineer but Ive been doing this stuff a long time and I'm getting ready for my retirement which just means I'm bulking up on tools. tooling and equipment for the next 10 years so when so I do retire I can do this all the time. It brings me great joy. About to drop the hammer on a small CNC lathe which will really help me on some of the more intricate internal parts that are big time sinks.
