Photo #3 : First parts complete: these four adapter assemblies will fasten top of rollcage to 1/2 in. dia. horizontal tubes that will serve as the backbones. Rollbar fasteners will be 5/16"-18; cross tube fasteners are 1/4"-20. |

Photo #5: Feb 4, '05: Adapters in place, clamped to two 1/2in. dia. horizontal tubes. Eventually I'll add two longer adapters forward, but the junkyard's out of the size aluminum I need. These will hold a third tube ahead of the other two. I'll weld plates onto both ends of all three tubes, connecting them fore and aft. Curved sections of 1/2 in. dia. tube will support fabric and EL-wire. These tubes will be bolted to the end plates. But I'm beginning to think the 1/2" dia., 1/16" wall backbones are too wimpy; I'll bore out the adapters and switch to larger dia. tubes with a thicker wall. These could be Formdrilled too... |
