## Identifying screwdrivers

Problem: When working on a ladder or other overhead platform, it is often inconvenient or unsafe to continually scrounge through the tool pouch to find the right screwdriver. Can the right one be found without a look-see?

Solution: Engrave the end of the screwdriver's handle and use your fingertips A straight line depicts a blade screwdriver, while an "X" indicates a Phillips tip. Use various size engravings for different blade sizes. Going over the engravings with a yellow metal marker makes for easier locating in low light conditions.

## Drilling drywall screws

Problem: When using drywall screws for applications other than drywall, the hole should be predrilled through the first layer. If fastening two layers of wood together and you don't do this, the screw jacks the layers apart. This occurs because the screw makes its own threads in the first layer and then pushes away the next layer as the screw point tries to enter. For example, when fastening the plywood cover on a shipping crate, a tight fit requires both a screw gun and electric drill. Is there a way to make this connection?

Solution: Use the screw itself to drill the clearance hole. Drive the screw in to a depth about equal to the first layer thickness. Then reverse the screw gun rotation and drive the screw out again. Continue reverse rotation and apply downward pressure to force the screw back through the first layer, which reams out this layer to the exact screw diameter. Once the screw has worn through to this depth, switch the gun back to a forward rotation and drive the screw home. The job is done with just one tool.

## Determining fork position

Problem: Knowing whether the forks on a lift truck are horizontal can often be a problem, particularly when operating at higher elevations or when the forks are inserted into a pallet. Is there a way to determine if the load is level?

Solution: Clamp or tape a piece of conduit or channel to the overhead guard. A quick glance comparing the position of the conduit/channel and the top of the mast indicates whether the forks are horizontal, or tipped up or down. The indicator bar must be placed high enough to clear the crosshead of the mast when it is tilted back.

### Annual Salary Survey

After two years of economic concerns, manufacturing leaders once again have homed in on the single biggest issue facing their operations:

It's the workers—or more specifically, the lack of workers.

The 2017 Plant Engineering Salary Survey looks at not just what plant managers make, but what they think. As they look across their plants today, plant managers say they don’t have the operational depth to take on the new technologies and new challenges of global manufacturing.
