The other thing you will need is a micrometer, or a fixed gauge. DO

the diameter of the needle determines the size of the stitch

NOT try to use calipers, they simply will not remain true- regardless
of how tightly you lock them down.

have an 100 plus year old set of calipers that will not move but like
the idea for a micrometer if the needles are to match and for selling

For a 14" needle, you will need a starting piece of stock around 20"
long, and 24" would not hurt.

is the length a personal preference or is it for performance reasons
