A one man hobby shop is immune to OSHA. We had MiOSHA go after our club when a member had a high level on a blood test. Guy has a basement range, is a CCW instructor, range safety officer, serious shooter, ect. We don't have *ANY* employees. MiOsha overstepped and backed off.
I'd get a bit worried about posting G code for a full auto varient, just because the feds have more time and money than you and if you need to pay for a lawyer, they just won even if you prevail. Semi auto stuff, go for it.
