Also static electricity tends to flow on the surface of wire, stranded/braided is much better (more surface area). Its pretty serious overkill on a home system. Hobby level wood shop fire is more likely because you hit a nail or something and get fire due to hot metal sparks getting in your dust. Or dirty blades can cause enough friction I imagine, that and BLO rags.

Out of my rearend statistics: I’m betting your more likely to be hit by a meteor than a fire due to static in your system.

Also a slight buzz that you felt at your friends house is voltage(AC) leak from some power source. Static doesnt buzz like that. It is a build up of DC voltage that discharges instantly upon connection with ground. He could have a ground loop somewhere in his system and really really needs to get that checked out, they can kill you.
