I'm trying a slightly different method I read online.
Scrape the flesh side 'til it's clear of all the crap. Couple of good handfuls of salt spread evenly on the flesh side. Fold the hide (hair out) so the neck covers the rump (let's call this North to South). Next tuck in any stragglers and roll the folded hide from "East to West". Tie it up loosely but securely. Stand it up somewhere, folded end UP. The salt draws the moisture out of the skin.
It was recommended to change the salt daily until the liquid stops running out of it but I got away with every couple of days.
When it's more damp than wet, hang it up somewhere airy to dry cure. The skin goes hard after a few days.
I'm at this next stage...
Re-hydrate the hide in a tub of water with a pound of salt per gallon and a cap or two of disinfectant (not sure what brands you have there but I'll be using Dettol). The skin soaks in the salt and disinfectant, killing off any remaining bacteria which was said to be the main cause of hair loss.
IMPORTANT...
When the hide has returned to the same wet consistency as when it came off the animal, rinse it out for a half hour or so (if I remember right). Hang to drip dry. When it's damp, work your tanning mixture into the flesh side. I agree that the neck and rump areas would need more work.
When I get 'round to doing my two skins, I'll post how it went.
