Installing new Edison diamond stylus

Just out of curiosity, what is involved in replacing the diamond on an Edison stylus? I just got a complete A 100 with a bad reproducer. The cord is broken and I can't really see a diamond on the stylus. I know you can buy a complete stylus, but just want to know how they do it.

This poor A 100 was literally in pieces. It's amazing, but the legs were intact; the case had fallen apart. It's back together now, but has to be stripped and redone. How are these machines compared to other diamond players?

Someone correct me if I'm wrong, but I think the process of attaching the diamond to the stylus bar involved electroplating the upper surface of the diamond, which was then soldered (or electroplated) to the stylus bar ??
I'm unaware of anybody making replacement silk cords, but there are several places that can supply a new diaphragm with a cord attached. These are not reproductions of the original style diaphragm, and don't sound quite as good, but they come pretty close.
The A100 was an early, and somewhat unsuccessful upright that was made between 1915 & 1918. The spindley legs & lack of record storage space seems to have been that models downfall.
It also used the no.100 horn, which was the smallest size, and was later used in models like the B-19 Chalet & L-35 London table models, and the H-19 upright. The sound quality difference of this & the largest no.250 horn isn't enormous, but the 250 does sound a bit better & louder.
