He also smoothed the surface for welding. |  The ASC framerails come pre-drilled...  The ASC framerails come pre-drilled with all the holes for installing the fenders, body, and running boards to the frame. By holding the appropriate-size nuts in place with their corresponding bolts, Herb welded the nuts within the framerail. |  Since the front boxing strip...  Since the front boxing strip will be bearing the weight of the engine, SAC welds a reinforcing boxing doubler on the underside of the front boxing strips. The doubler is 12 inches long. To approximate where the engine mount will be welded to the frame, the center of the doubler is located 28 inches back from the front of the framerail. |
 Using the MIG welder, Herb...  Using the MIG welder, Herb tack-welded the center boxing strip into place. A production welder, the MIG welder is used for this application. It produces a great deal of welding material, allowing the welder to quickly tack-weld the strips into place. |  He tack-welded the doubler-enhanced...  He tack-welded the doubler-enhanced front boxing strip next. |  For the seam welds between...  For the seam welds between the boxing strips, the MIG welder was used once again. |
 Before laying down the heliarc...  Before laying down the heliarc TIG bead welds, SAC's fabricator ground smooth the tack-welds. |  As it produces the weld material...  As it produces the weld material more slowly and enables a better-controlled bead weld, the heliarc Tungsten Inert Gas (TIG) welder is used for more artful precision welding. Herb used the TIG welder to finish welding the boxing strips to the framerails. In fact, he employed the heliarc TIG welder throughout the rest of the frame build. |  Once the bead welds were finished,...  Once the bead welds were finished, a 24 grit-sanding wheel was employed to begin smoothing the bead welds. Then a 60-grit wheel was utilized on the electric grinder. |
