Just made a bowstring from 65lb Powerpro (spectra) fishing line, as I was told it is the same as fast flight. I definitely like the lack of stretch compared to B-50, but I am still working out thicknesses. I used 12 strands and padded the loops with b-50. However--after serving the middle it was still too thin for my arrow nocks. Double serving the nock resulted in too much thickness--my arrows are now too snug.
Am I okay with 10 strands for a 55 lb bow?
How many strands and how long should I make my loop padding?
The string Mike Roberts in England made for me for my trade bow is a work of art in itself. Mine are serviceable at best. What is the secret to clean, pretty bowstrings?
