Master Wire Gauges with Draw Plates and Draw Plate Tips

by Dale Armstrong
Question 1:

When trying designs from directions using copper wire, I always seem to have the next size wire (for example, I have 20-gauge when it calls for 21-gauge). Would the wire work just as well if I were to purchase a draw plate and use it to make the correct size wire, so I would not have to have so large an inventory of wire? Would the wire be just as smooth?

Question 2:

Hi Dale, I'm curious about draw plates and how to use them. I purchased two draw plates somewhere about a year apart and both times the holes were huge compared to the stamped size they were supposed to be. I would like to know things like, can you pull gold filled wire through a draw plate or would it take off the gold? How long a piece of wire does a person start with? Do you have to heat the wire on every pull? I can't find these or any other in-depth answers about draw plates anywhere and believe me I've spent hours online trying. I need almost all the steps involved in using a draw plate.

Answer 1:

Actually, Peggy, since you're practicing a design using copper, I don't think a draw plate is always necessary.

Most designs can be made and practiced using just 22-gauge wire.

Pulling wire through the holes of a metal draw plate narrows its shape.

If you choose to use a draw plate, your wire will be smooth after pulling it through.

However, it will also be harder, because the process work-hardens the wire.

Answer 2:

Dean, the marked size of a draw plate hole refers to its outer dimension.

When pulling a single wire strand through a draw plate to reduce its diameter or change its shape, it's important to prepare one end carefully.

Cut and file the wire end to a fine, thin point so it can fit through the smaller holes.
Pulling by hand can be a challenge as the wire gets smaller. Folks who draw wire all the time will often invest in or build a Draw Bench.

With regard to drawing gold-filled wire: because the gold layer is heated/fused to the brass core, the gold will stretch with the wire, and there should be no problem until you pull the wire several times through progressively smaller holes.
