Re: Tool Tips -- rectangular holes

 

I clamp a short length of angle iron along the line of the opening, and file to that. Gives nice straight line. Rectangular chassis punches are available but are verra costly, and the larger ones require lots of force, and may need an hydraulic press. FWIW. 73 Kevin VK3DAP / ZL2DAP
