Metal Ring Mandrel Gague


#1

I just got a new shipment of ring mandrels into the shop and they
were packaged with a short adhisive strip that was numbered from 0 to
16. The mandrel itself is, of course, already permanently marked, and
this sheet is very short - perhaps 2.5 inches or so in total length.
Although I haven’t checked it against my standard ring sizing
templates, could this be a sizer? It just seemed odd to be getting
this in a mandrel and I was wondering if anyone had any insight for
me.

The strip shows Shank size. Length of metal required to make the
size.

Sandi,

If this strip is approximately 3 inches long and there is a space
between the 0 and the 1 of approximately 1 1/2 inches than this is
for measuring sizing stock and ring blank stock.

For sizing a ring simply use a pair of dividers to measure the space
between 1 and any number to figure the amount of material to add or
remove from a ring for sizing. ( example: you need to size a ring up
2 sizes so you use your dividers and measure from 1 to 3 on the
gauge. this is two sizes and the amount to mark on the sizing stock).

For creating a ring from stock you measure from 0 to the size you
need (example: you want to make a flat wedding band in a size 6 you
would measure from 0 to 6 on the gauge). When doing this make sure
you allow for the thickness of the stock.

Good Luck

Hi Sandi,

I just got a new shipment of ring mandrels into the shop and they
were packaged with a short adhisive strip that was numbered from 0
to 16. 

If it’s the strip I’m thinking of, it can be used when sizing a ring
up. It’s used to measure the length of material need to make the
increase in size.

I usually set a pair of dividers from the strip & then scribe the
sizing stock for cutting.

I believe it is a sizing chart for when you are measuring/altering a
ring shank or blank. One size is equal to 2.2mm. So if you are sizing
up or down, if it is the gauge I think it is, you can refer to the
numbers on it as a quick reference to how much metal to take away or
add when sizing.
