Re: Making new cable ends
I leave a good bit of extra cable and where I want the end to be I use an awl and make a "hole" in the cable so that I can fit some copper wire through (From an extension cord stripped and separated into strands)... then I close the hole and wrap the cable a few times with the few strands of copper wire. Dab on a bit of flux and then add a bit of solder with a soldering iron... letting it make a "blob". Now I cut off the end at the soldered point (dremel tool cutoff wheel) and if need be shape the blob to size with the dremel and grinding bit or sanding drum. Takes longer to explain than to do it. The solder bonds nicely with the copper wire and makes for a solid end.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
