Review on Alvin TD1312 Electrical Controls Symbols Ruling Template - 3.75x8x0.03 inch by Nicole Mcleod

Part of my job as an Industrial Electrician is drawing diagrams for new or modified machines and this Alvin TD1312 is really well suited to its intended use which is to make it legible and easy to read . prints "for the next man to work at this machine". The stencil itself is a fairly durable translucent green plastic that lays down nicely and evenly. I don't normally abuse my stencils, but they seem to last for years with good care. The only thing I don't like about it is that the three-phase motors and indicator lights don't go all the way around. Whether Alvin did it for longevity I don't know, but the unfinished lines they leave drive me nuts. >.< But everything else is correct, and the symbols for the double voltage converter and the time delay relay are welcome.
