Sheesh, what I thought would be the 'easy' part of finishing the riveted silver/glass rings I had in mind, turned into a frustratring mess.
As always seems the case with my learning process I have to muck things up a couple of times then undo and redo them before I 'get' it lol.
So third time lucky? Nope.
Simply hammering the silver tubing down into a rivet using a dapping block and punches which I figured would take a matter of minutes took over the majority of my silver class work time.
The fist ring I completed without breaking the glass I broke the silver instead! Grrr. the tubing started to split on one side and once that happened it was impossible to hammer more without worsening the split, resulting in a 'pacman' shaped rivet, shown on the right (yeah I totally meant for it to look like that:/ )
What I learnt from that though was that my tubing was tooo long and it only takes an extra 4mm above the bead to make a rivet without a pacman split, maybe even less would be better.
