Safety Wire – Dave’s Garage

Recently, an acquaintance with an MG TD changed his oil. He happened to notice that there were some metal wires in his used engine oil. I suggested he drop his oil pan and have a look to see where the metal came from. It is a good thing he did. The person who rebuilt the engine did a lousy job safety wiring the main and rod bearing caps.

Fortunately, nothing came loose, and his engine did not grenade. Here is a chart showing the proper way to use safety wire. Following this chart and using a little patience and common sense you can properly safety wire your own projects.

How to properly tie Safety Wire

Safety wire pliers are available at many tool stores and on Amazon. I buy my safety wire on Amazon, they seem to have the best price.

Speaking of safety, always securely clamp sheet metal when drilling holes. I was making a patch piece today, a piece about the size of an index card. The piece was going to be butt welded on three sides, and spot welded on the fourth side to duplicate the factory sheet metal. I was drilling several 1/4 inch holes every inch or so on one edge for the plug welds. I had the piece of sheet metal on a piece of scrap wood when I was drilling it. I had the drill in my right hand and was holding the metal with my left. The drill bit grabbed the metal and spun it, cutting my hand. I spent the next five hours in the Emergency room getting stitches in my left hand.
