Solder loaded into cordless gun: Soldering electrical connections is now a one-hand job with the new rechargeable Iso-Tip Cordless Soldering Gun from Wahl Clipper Corp., Sterling, Ill. From a supply chamber at the rear of the gun, 0.062-in. solder is channeled through a tube to the tip when the trigger is fully depressed. Up to 125 electronic joints can be soldered on a single charge; the gun recharges in 4 hr. Cycolac-brand ABS engineering thermoplastic, Grade T from Borg-Warner Chemicals was used for the injection-molded gun case to provide it with high impact resistance.

Flexibility of these components decreases rapidly as the load increases to keep the entire suspension system “in tune” with the load.
