I've been able to splice the 3 strand silver since I was knee high... Braided rope is very much a different story.

I understand the process (I think) but need help on the last bit. For those that know how to, or have followed any tutorials on youtube, the bit I am having trouble with is what is normally marked as 'B' where you first pull the core out of the cover. When it comes time to putting the core back into the cover and you go an inch or so beyond point 'B' where you are essentially trying to double up the core in the cover (and where the eye is basically formed), all the tutorials show the rigger effortlessly sliding the fid and core as far up as they deem necessary. I on the other hand push, pull, bang, swear, have gone 2 fid sizes down, swear some more, tapered the core and the best I can do is come out at 'B'.

I want to learn this more out of determination now than an actual need to do it. Anybody got a handy tip

(Does any of that actually make sense?)

If it makes you feel better, I have the same thing. Maybe riggers develop huge muscles! Still, the splices come out really well.

I've never tried the Bunnings rope, but it wouldn't surprise me if that cheap imported stuff wasn't designed for splicing. I always buy Donaghys from ropegalore. Although my first one or two attempts were a bit like you describe, after that I've found it relatively easy to splice. Sometimes you need to work the cover around a bit to expand it and make room inside.
