That's what I used to do Dennis before I got my super duper little torch.

A couple of days ago I soldered a pierced out .7mm strip onto a 18cm x 2cm by 1.65mm piece of silver to make a man's cuff. Took me a whole afternoon to get it to work with much swearing and cursing. I was using the rosebud (?) tip so was getting loads of heat but I just couldn't get the contact right. I tried all sorts of clamps, including the titanium ones and in the end I used abut 20 bits of binding wire and eventually it worked! I won't be making another! All good experience though.
