Sounds complicated Ben!
If I have to spool a reel up by myself, an easy way to do it is to put a wooden dowel in a vice, then an old CD or one of those clear blanks that you get in a spindle of blank cds, then the spool of braid. Put a second similar plastic disc on top of the spool, then place a dumbbell weight on the spool - assuming you have one laying around. Having the spool sandwiched between two large smooth discs just makes the process run a bit smoother.
I like the line to go one very tight, so there will be a decent bend in the rod when you are winding it on, and your cranking arm will get pretty sore as you are doing it. Seems to work well though.
One day I will make up a spring compression line winding device but until then, this works well.
