I was wondering if anyone has any advice for making a square band to the proper size.
I recently made a ring (the lapis ring in show and tell). My friend had requested a 7.5.
I cut the wire to length as calculated from a table. Once formed on the round mandrel (before solderig) it was a little smaller than a 7.5. Once soldered and hammered on the round mandrel, it sat just above the marking for a 7.5.
Once shaped on the square mandrel, it still fit the finger I was testing it on, though less snugly than when it was round. When i checked the size of the squared ring on the round mandrel, it was about 6.25.
When I gave it to my friend, it was too big for her ring finger. (it did fit her middle finger, so we are good).
Does anyone know the rough size conversions for square to round bands? Ie square band should be 1 size smaller than round band? Should I have done something differey? (I somewhat suspect that my friend sized her finger incorrectly.....but not positive.)
I see a purchaser of those blue ring sizers in my future.
Does she have a ring that fits well on that finger that you can measure with your mandrel?
The size is the same no matter the shape. The squared shape mimics the actual shape of the finger, so may put up less resistance when putting it on vs a round ring. Top-heavy rings, especially, flop around if the fit is the least bit too loose.
One thing you need to do when you get your ring sizer is try it on your ring mandrel. If there's any discrepancy, you need to know about it so you can compensate.

Thanks Andrea! That is a great idea! I think she measured her finger wrong. The ring fit on me as a 7.5, an round was a tad smaller than a 7.5 on my mandrel. I usually do determine size by checking the size of an existing ring, but in this case she lived far away so I had to go by her measurements.....
