Hi - decided to invest in a ring stretcher back in February and having waited a couple of months for Cookies to get them back in stock it finally arrived mid May.
Works great for stretching BUT noticed with the first ring I re-sized that I had marks on the inside, which I thought I had filed/sanded before putting on the ring stretcher, but decided that I couldn't have, so refiled and sanded. No big problem but was annoyed with myself.
Second ring resized - same issue - and I definitely made sure the inside of the ring was smooth first.
On checking the ring stretcher spines, they seemed a little bit sharp on the edges especially when opened up, so thinking this was the cause of the marks I sanded them with smoother with emery paper.
Next ring I did was a little better but still marking.
I have reported the issue to Cookson with photos, and they have referred the issue to Durston but two weeks later they haven't had a response (although to be fair there's been a bank holiday in-between).
So just wondering whether significant clean-up is to be expected after stretching. The attached photo is of a test ring I did, 1.85mm sterling, rounded with rawhide mallet after soldering, inside sanded smooth. Then put on the ring stretcher and increased by one size. I used platinol on the inside of the ring just to highlight the marks I am getting - they are quite deep and will need filing to remove.
Thoughts? Is my ring stretcher faulty or are the marks to be expected?
Thanks, Susie
