When I unwound my RIHS years ago, I wanted it to match the scatter wound Toaster. The toaster and RIHS are constructed the same way with alnico rods as pole pieces, so I thought it was a good idea to have approximately the same number of turns on both in order for the RIHS to match the toaster in output. I cannot remember how I came up with 8.2K back then.
For some reason I have thought the RIHS bobbin to be larger than the toaster bobbin. I wound up a toaster and a RIHS bobbin a few days ago (I should have measured the bobbin cores when I had the chance, but I didn’t think of it) with 6500 turns of AWG43 on both, and both ended up with 6.7K. So I guess the two cores are equal in size.
So, if one wants to match the number of turns on both pickups (toaster and RIHS), unwind the RIHS to the same resistance as the toaster.
Current Lollar HS have resistance readings slightly less than a toaster, about 7K (+/-) if I remember correctly. Due to the construction being different (pole screws instead of large alnico rods), the core of Lollar’s HS bobbin is probably a little bit smaller than the toaster. With 7K of AWG44 on Lollar’s bobbin, I guess it has close to 5500 turns on it.
Don’t know how many turns of wire that will bring the RIHS closest (soundwize) to a real HS, but 5500 turns might be a good start.
For reference if someone should have any use for it, here is my table of resistance estimates (based on unwinding and counting turns, and my own winding) that should be valid for both the toaster and RIHS bobbin (estimates are not 100% correct, but close enough).
number of turns with AWG 44:
5500 => 7.18K
6000 => 7.84K
6500 => 8.49K
7000 => 9.14K
7500 => 9.79K
8000 => 10.45K
8500 => 11.10K
9000 => 11.75K
number of turns with AWG 43:
5500 => 5.70K
6000 => 6.21K
6500 => 6.73K
7000 => 7.25K
7500 => 7.77K
8000 => 8.29K
Btw, my resistance measures are at temperature 20C.
