I, apparently, have a Chart fixation.  I need to stop making them!

Finishing Charts

Ring Charts

Soldering/Torch Related Charts

B&S Gauge Charts

Drill Bit Charts

  • Drill Bit Chart:  Use the Drill Bit Chart to determine which drill bit will be a perfect fit for your wire. How many millimeters is that drill bit?  I have a 16 gauge piece of wire – what size drill bit do I use to match it?  This chart shows you drill size to wire gauge, drill size to bit size in millimeters,  wire gauge measurements in millimeters,  wire gauge in millimeters to the closest fraction, and wire gauge to the closest decimal equivalent.
  •  Drill Bit Sizes in MM’s and Decimals – (Smaller Sizes) with closest Matching B&S and A.W.G. Gauges. This Chart shows the different Standard (USA) drill bit sizes in Metric and Decimal.  There is also information on which size and type of drill bit match the gauge best. There are several similar charts to be found on my website – guess I have a thing for gauges and drill bit charts.  The B&S Gauge is a much simpler chart.  I use it on my bench.  The other gauge charts show my Obsessive Compulsive side very well! How many charts like this does a body need? Well, no more!
  • Gauges and their Closest Matching Drill Bits with Lengths per Ounce for Silver. This chart presents the B&S & AWG Gauges and their closest matching metric and standard drill bits.  The sizes are shown in metric and decimal. Also, general lengths per ounce for silver are listed.
  • Setting Burs.  A list of gemstone sizes and the corresponding setting and/or hart burs for cutting seats.  Lots more information too!

Decimal and Percent Charts

  • Decimal and Percent Chart: The Decimal and Percent Chart comes in handy if a supplier lists tubing (or some other part) in fractions and your stone is sized in millimeters. Using this chart simplifies conversions and does away with all of those nasty little mathematical formulas (although, it is nice to know them).

Jump Ring Related

  • Pepe Tools Jump Ring Maker Sawblade Chart.  This chart took HOURS to do!  I had to test all the gauges with all the different mandrels.  Anyhoo, it’s done!  This chart will show you which size saw blade to use with which metal gauge and with which size mandrel!  It will help you to save your blades and get better cuts on your jump rings.  Watch for my new video:  “How to get the most from your jump ring cutter” on YouTube, coming very soon.

Sawing Related Charts

  • Saw Blade Chart: Knowing which saw blade to use can have a big influence on your work. That’s where the Saw Blade Chart comes in.  Using the wrong blade can result in wasted metal, difficulty in sawing, and creating lines that are too thick or thin.  If sawing is difficult, try changing your blade size – it can make a huge difference.  This chart shows you what saw blade to use with what gauge of metal. It also shows you how many teeth each blade has per inch or centimeter.  This chart covers the thickness of the saw blade and what drill bit to use for that blade. Watch my two videos on sawing: How to Saw.

  1. Hi Maral, Thank you so much for the wonderful comment – I really appreciated your kind words. Don’t worry about the “proper” jewelry methods – if something works, the way that you are doing it, then it works. Obviously, you don’t want to have to reinvent the wheel but, sometimes the best stuff comes from people who adventure into the woods! Did you subscribe on my website? If you do, it will be easier to announce when and if, I am teaching a class. I’m working on one locale now. I am waiting to hear back from the venue. I haven’t taught live for awhile and would so love to see those “bright, shiny faces” and get live feedback. Teaching is almost as good as creating. Thanks again and go for it! Take care, Nancy

  2. Nancy – another grateful fan here. As a relative newbie to ‘real’ jewelry (sterling, soldering, studio, etc.), I thank you *so much* for your generous, clear tutorials/tips – and now this handy, one-stop place for these amazing charts. I’m currently trying to elevate my work to include ‘proper’ jewelry methods/materials but feel pressured to learn only what I need to know… need a crash course. And I *so* appreciate your knowledgeable, personable, generous help – you seem great. If you do start classes I may have to travel up for them.

    Thank you, Thank you, Thank you!

  3. Hello Nancy
    Thank you for sharing your information and really helpful videos. Your work is wonderful and you are inspirational!

  4. Nancy!
    Thanks so much for sharing all of this great information.
    You’re my new favorite person, seriously!

  5. Hi JoAnne – Glad to be of help. It took me a while to find all the information, so I know what you mean – but, I was a woman on a mission. Thanks for traveling around my site. Nancy

  6. I just wanted to say thank you! I have been searching all over for a chart that tells me what drill bit size to use for different gauge wire so I could make rivets. I couldn’t even find this in books I own.
    Thanks for sharing ~ JoAnne

  7. Kay, You are so right and I am so sorry. If you hover (on my website, charts) you see the chart listing and that works. BUT, if you go to the chart page, the link to the drill bit chart didn’t work. I’ve fixed it, so try again, thanks for watching and I’m very sorry! In case you don’t know (but, you probably do) and you want to copy the chart, right click on it and copy image. You should be able to paste it to some type of program like Word or Photoshop. I also uploaded the flush or invisible rivet video to my website and you can find that under recent posts, on the right hand side of any page or here, at this link: . Let me know if these things don’t work. I appreciate you taking the time to comment AND to watch. Thanks. Nancy

  8. Hi Kayci, The reason you haven’t seen the flush set riveting is because my producer has moved and hasn’t uploaded the next three videos. Soon, I hope. As far as the link thing, did you go on my website to “Charts”, “Drill Bits”? I just checked it and it appears to be working. If you still have a problem, please let me know. I really appreciate you watching. I’m really glad these videos are useful! Thanks. Nancy

  9. Thanks for all of your YouTube videos, they are very helpful! I have watched them all – and on one regarding riveting, you mentioned a second video on “flush set riveting” – I was hoping to watch that one, but I don’t see it.

    However, the main reason for this note is – I was hoping to get the drill bit chart, but the link is not taking me to the page – I did search for it – but I can’t access it.

    I will check back at another time –

    Again, thank you for your helpful videos.

    Kayci Vandegrift
