3 4 STEP 3: COMPLETE THE PATTERN Although we could have patterned all four sides of our piece, we saved a little time by patterning just three–we could derive the last side from the other pieces. We numbered the patterns to keep them in order and used witness marks to ensure proper alignment. STEP 4: MARK UP THE TUBING We then transferred our patterns to our 2x2-inch tubing, making sure to line up the witness marks. Note the gray marking pencil, which we kept very sharp. These pencils are great for fabrication projects and are available at welding supply stores. STEP 5: BREAK OUT THE SAW A cutoff wheel ftted on a die grinder easily cut the tube to size. A bandsaw, hacksaw, chopsaw or reciprocating saw could have done the work as well. STEP 6: DRILL ATTACHMENT HOLES Our cradle needed a way to attach to the rubber engine mount. We drilled an 8mm hole on the other side of this arm that could accept the rubber engine mount's attach- ment stud. This side then needed a larger hole so a socket could tighten a 14mm nut onto the stud. We used a 1-inch hole saw to drill that hole. 5 6 Grassroots Motorsports 138
