DIY Watch dial feet soldering machine

It all started with a PDF file with chapter XX "Dial Positioning For Retrofits" of the book "Quarz Watch Retrofitting Manual" from Wesley R. Poor. After checking other sites and resources I wanted to make one myself as the price for a ready made one is 300$ plus depending on the brand.Project: Dial Feet Soldering Machine on a budget.Items bought add up to 35€ and the rest are out of the odds and ends box.I use a transformer, open design, 2 x 6V as this was available in the local electrnic shop. I use 6V as written in the PDF file.The carbon rod is from an zinc-carbon battery glued into a little plastic tube and then drilled so that a standard 4mm banana plug cabel assembly can be used.For soldering I use copper wire, "Löthonig" as flux and lead free 99.3Sn0.7CU solder.
Now it is training time, the little machine is working fine, only the process of working has to be trained to get some feeling. I will post a video soon showing how easy it is to solder a new feet on a watch dial.

Cleaning the spot for soldering is essential and the the solder paste needs to be properly around the copper wire to give a good joint.
