Re: Scale model Carter
Doing that math then it equates out to 14.767 and 12.232, which really isn't sticking with that 5:6 ratio

Scale model Carter
I'm looking to make a scale model of a Carter Type 1H air raid siren out of a bench grinder. Can anyone help as far as telling me how can I make it sound the same? Especially since it turns about 3600rpm instead if 2840rpm
