April Bower | ONLINE: Spectacular Spiculums | June 8th, 10th and 12th, 2021


What the heck is a Spiculum?

It’s a closed anticlastic formed shape you will love to make!

SPICULUM:  Noun= Small hollow pointed form 

(Very useful in jewelry making.)

This is an online adventure in forming.

Make as many of the practice spiculums as you’d like! We will start with a pair of  simple straight spiculums that make great earrings or linked elements, then create a statement piece necklace, working in copper, brass or silver…your choice

 Featured techniques:

forming spiculums & tubes

create a wrapped tube bale

bending commercial tubing for curved bales

knowing the tools necessary and how to make or improvise your own


soldering, assembly and connections

How to Balance bail to pendant

Tube setting a facetted stone

DESIGN: what makes an overall strong design

finishing techniques/ patinas


Work with your own tools in the comfort of your own studio.

Laptop or Tablet recommended for viewing, and cell phone camera for sharing photos of your project if you have questions for April.

Please familiarize yourself with Zoom and make sure to download the Zoom Apps on your devices.


We know this is going to be a very popular class!

bench pin and clamp

Small smooth anvil or bench block

leather  or non-mar mallet,

planishing hammer or very smooth smaller metal hammer to close spiculums (closing hammer)

any nylon cross peen forming hammers you may have ( smaller metal cross peens will do in a pinch) for example: NC Black closing hammer

Fav texturing tools / texturing hammers

Grooved wood block or “Whammer”

Chain nose plier

Flat nose pliers

round nose pliers

good metal shears

6″ flat file or inside ring file (flat one side, half round other side)

sanding sticks

Sharpie pen,

Millimeter gauge

drill press &/or flex shaft,

#55 drill bits and 5mm setting burs, or individual setting bur 5mm (Setting bur the size of your facetted stone )

wax stone dop, Sharpie marker

tube setting punches ( size 20 or 19 : they run small)   and chasing hammer for punch,

(your usual hand tools: saw & blades, metal shears, ruler, scribe, flex shaft clean up burs/ grinders pliers,  optivisor.,

Studio Tools


use what you have. Bushier flame is better than small pinpoint flame for annealing.

Heat proof surface for soldering/ annealing; Solderite board or charcoal block

flux: white paste kind for Red Heat Patina like Handy Flux

patina: Your favorite blackener: Liver of Sulfur, Gosiba, Jax, Black Max for silver stamped texture

Polishing lathe or flex shaft and burs for cleanup and polishing.   * 0000 steel wool and pro polish pad will do.

black silicone wheels. Are great for all around abrasive clean up with your flex shaft. Get the mandrel too as it doesn’t come with it. Flat edge shape is very useful too.

Optional and fun things

Rolling mill to texture or step thin spiculum metal

I use the 3M radial bristle disc  in Blue (400 grit) peach (60 micron)  and light green (1 micron).If I had to only buy one I would choose blue (400) as all around most useful. They come in small for flex shaft too. Buy lots of screw mandrels for them.

Moores  Sanding disc  and  snap on mandrel discs come different grits. Choose med & coarse over fine.

black silicone wheels. Are great for all around abrasive clean up with your flex shaft. Get the screw mandrel too as it doesn’t come with it. Knife edge shape is very useful too.

Bezel mandrels set from Otto Frei, seems like a great deal.

Tube setting punch Otto Frei has “replacement” punches individually up to 6.5mm. They run small. I suggest  buying one  2 mm larger than your stone. May not work with cabochons unless they are very low dome but great for facetted stones. A set is always best, but the price range goes with the quality range. bezel setting set: a low end, but usable set.

Wubbers Parallel jaw pliers for Croissant style bale
