I've never been involved with 1830 rope starting but I've heard a few bar tales about it being done by our pilots (this is going back a few years; I've forgotten the technique). Nothing that couldn't be solved after a bit of experimentation. Probably a short fore and aft lay on the dome followed by rotational wraps. I'm not so sure that it would be a good idea to wrap the rope around a blade root!
I haven't seen inertia starters and their associated hand-starting gear on Daks for many years - they all seem to have direct drive units now. Shame - it used to be quite satisfying to start one single-handed
