This is an old make I dug out with news of the passing of Jimmy Buffett this morning. My wife and I are long time parrot heads. RIP Jimmy
This is a shark fin I made circa 1998 that bolted to roof rack of our mini van for concert road trips. The fin is cut from 1/2” plywood. The base of the fin is made from 2 pieces of 2x4 that sandwich the fin. All bolts are made from 1/4” all thread with associated nuts and washers.
The base was notched on both ends to fit on the cross members of the roof rack system. Clamps were made from 1/8”x1” steel strips and 1/4” all thread bolts.
Got so many people pointing and snapping pictures as we went down the road.
