Pit Tips

Cheap wrench tip replacement

If you have hex wrenches with replaceable tips and you happen to break one of the tips, you can modify a cheap L-wrench and install it in the handle. Just cut the wrench at the bend so that it’s straight, and install it in the handle. The new tip will work until you get a proper replacement.

Easy-to-make diff ball container

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.

Easy De-Chrome

If you want your tires to stick securely to chrome rims, you must thoroughly remove the rims’ shiny surfaces (unless you have the latest Pro-Line chrome rims). Use an eye dropper or a rolled scrap of Lexan to funnel a little lacquer thinner around the rim. This will soften the chrome plating enough for you to wipe it away. Be sure to work in a well-ventilated area.

Magnetized parts bowl

There’s nothing worse than losing a screw, E-clip, or other small metal part when you’re wrenching on your car, so Matthew uses a magnetized parts bowl from Sears to hold small parts when he works on his gear. Make your own magnetized bowl in any size by adding a stick-on magnet (available from the craft store) to the bottom of any metal container. You can also use the magnetic container to find lost parts when working over a carpeted floor. Just slide the magnetic base over the carpet until it grabs the missing item.

Rim reminders

After tires, inserts and rims are all glued together, there often isn’t a way to tell your various combos apart. When you finish putting a set together, write the insert?s firmness, the tire?s compound and the offset of the rim on each rim. This is a 53-compound tire with a medium insert on a 2mm offset rim.

LiPo-Powered Starter Box

Larry Demarco >> Chicago, IL
If you’re looking for a little extra engine-cranking power, replace the NiMH batteries in your starter box with high-capacity LiPo batteries. You’ll need to invest in a Li-poly charger to charge the batteries, but it is well worth the cost because the batteries provide more voltage, and they do not discharge when not in use. Just remember to disconnect the batteries before storing the starter box.
