Okay, somewhere on the forum ( I do not no anymore who, where and the subject involved), a topic about covering the prop blade tip with metal, it was a four blade prop, that I do recall.
Anyhow, it inspired me to try something my self.
I used alu sheet - 0,11 mm - ( used by book printers way back in the past).
I annealed it with a torch for a very short time ( other wise the alu will melt).
Cut to shape, glued on with epoxy and let it dry for a while.
Fine sanding completed the process, rivet with a fine needle ( this was done in a hurry, no fine sequence)
After annealing, the alu is very malleable.
