There are 3 small holes marked out in front of each axle. The lower 2 need to be drilled through to carry the shoes. Find that my newly-purchased 0.3mm drill bit is too small for my minidrill, so I use the tip of a larger broach till it breaks through, then open the holes out with a small broach till they’ll take the brass wire.
Don’t fancy folding the shoes accurately by hand. Conveniently my 1mm thick steel rule helps keep the angles square.
Just a blob of solder inside the shoe. I need to keep one wire long to help fix to the rigging. Now to try the shoes in place around the wheels
I find that there's slight contact, so I need to file the back of the shoe just a fraction.
Now the wheels turn freely, I can worry about the rigging.
