A short piece of fuel tubing with a screw on each end makes a perfect container to store 5/64 to 3/32-inch diff balls. Squeeze some diff fluid inside the tubing before you insert the diff balls, and then you’ll be able to squeeze out one lubed diff ball at a time for easier diff building.
Sanding graphite parts can make a real mess, and it isn’t healthy to breathe in the particles. You should always wear a mask, but you can cut down on the mess by sanding the parts while holding them under running water. The water will carry away the graphite powder and prevent it from getting on your hands and traveling through the air. Mike Herpen Tabernacle,
Small plastic tool caddies like the one shown here are perfect for hauling your nitro support gear from the pits to the track. Most tool caddies have two or three compartments to store your glow-plug igniter, temp gun, shaft starter or EZ-Start, fuel bottle, tools, extra glow plugs and more. I picked up my caddy at the local hardware store for less than $4.
To prevent the slipper pads from falling off of the spur gear when you mount them, use a glue stick to run a small line of adhesive around the pads. The glue is strong enough to hold everything in place, but it isn’t permanent. Apply the glue only to the side of the slipper pad that goes against the pad mount. Kyle Jarratt Arroyo, CA
If your radio has multiple-model memory, but only has a number to represent each model, it’s easy to forget which model belongs to each number. A strip of masking tape stuck to the back or bottom of the radio is perfect for making model-memory notes. Or, you can put number decals on your cars to match the memory settings.
Tired of dropping those tiny differential balls? Use the tube of diff grease to pick up the balls. Just squeeze a dab out onto the tip, and use the sticky stuff to pick up each diff ball and put it into its hole in the diff gear.David Andrews – Ripon, UK
