Nice Powerplus MF
50/50 acetone atf is one of the best penetrating fluids around - there was a restoration show on abc the other month and he was using it as he said it was the only thing that would get 100 year old seized things moving.
I have done Norm's method many times and it works really well. I ziptie and elastic band a rolled up gladbag or ziplock bag at the top in a fashion so it forms a funnel. That way you can leave it overnight and not have to keep oiling it every hour. Also, the 'head' of oil tends to get it through quicker as well
Make sure to put a bucket under the other end as a fair bit of black dirty oil will come out the bottom
Have also seen the same thing done with bluetack formed around the cable (just make sure absolutely no grease on the outer cable first)
