is for hobby use at home

If you don't need a whole lot of strength (based on the wire size, you probably don't!) then soldering would be the most expedient means to connect the wire. It could be done with a low heat torch and is much easier to do properly than brazing.
Consider using a high tin solid solder with appropriate flux for the application.
