Hi, I've been having a go at this malarky for about 3 or 4 weeks now, ever since my wife did a short course.
I've made about 5 rings - all of which came out a size or so bigger than I was intending. (I use the [int dia + thickness] x pi to get the length.
I'd thought I'd share my latest and best fail with you all. I was going to make a ring for my daughters 18th, a small 2mm (£30!) diamond set in a blob of gold and a blue saphire either side in the silver ring (sept = saphire)
Well - I dropped the diamond 3 times and spent a good 90 mins searching for it, when I did finally mount it this is the result - spot the deliberate mistake!!!
I won't bother to finish it, it's in the tumbler to see if it shakes the diamond out, I suppose I could re drill it and mount a bigger cz or something.
All part of the fun.
Cheers
Martyn
