I recently purchased an older Robert August 6’6" swallowtail. Had to do a few repairs to make it watertight, but otherwise good condition.
The plastic fin attaches to the fin box with a special screw which has an eyelet for attaching the leash.
The screw is a special number: #8-32 threads with a special eyelet, all done up in brass.
Unfortunately, the threads are stripped.
Does anyone know where I could acquire one of these little gems?
Don’t know a source for one, but here’s how you could make something similar :
Buy an appropriate brass screw from McMasters Carr. Get one over length
Heat up one end of the screw pretty hot (no hotter than really dull red for brass) and then pound it flat with a hammer on a heavy block of metal (anvil)
Let cool and drill your small hole
clean up with a grinder after making sure its well gripped in a vice
Can you provide a clear photo of the fin box? Those old fin bolts for attaching leashes were typically the same thread as a standard FU fin screw. I’ve never seen one that had a different thread. Never.
In any case, those are a bad way to attach a leash. Notorious for ruining the box and fin.
