Dapping Metal or Wood

Hi Stacy, Can you give me some beginner info on a dapping block wood vs metal. How to judge which size on the block to use. Thanks I appreciate any guidance here.

Both tools are important bench tools and I use them frequently. They are both for doming metal, more specifically round discs, but you get a different look with each one. Here are some differences between the two, plus some advice on how to use them.

Basically, dapping cubes are created from high-grade hardened steel and sometimes wood. Designed with hemispherical depressions or dies in varying sizes to give a curve to flat soft metal discs as seen in bead-caps.

The wooden dapping cubes do not have as many choices in the size of dimples to choose from (6 being average). They are also usually more shallow than their metal counterparts. Because wood is soft, it will not mar or damage the design youve added to the disc as you dome it. As long as the disc is pattern-side down, you can hit it using either the round part of a chasing or ball pein hammer, a steel dap or one of the wooden ones they usually come with. If you are needing to make the disc concave with the pattern on the inside, then you would place the disc pattern-side face-up. Using the wooden dap to shape the disc will not distort your texture pattern.

The wooden cubes put a nice gentle dome on a disc. I tend to use the largest dimple because sometimes discs can get stuck in the smaller dimples. You can dig them out, but its rather a pain. 🙂 Wooden cubes are very inexpensive and come in a variety of sizes from very large to the standard 2-3 inch cube and even flat-ish rectangles sporting several different dimples.

The metal doming blocks have more dimples – 18 being standard. The metal dimples are much deeper than the wooden ones creating a more dramatic arch to the disc. They are great for forming bead caps and lentils, pods for earrings and necklaces, etc. Because hitting steel-to-steel will damage any design you may have in the disc, you must place a thin, soft protective barrier between the disc and the dimple. They are available in steel and bronze.

Steel dapping mandrels or punches to go with the steel cubes can be purchased together with a cube as a set or separately and vary greatly in price. The punches are used with a dapping block to press the metal into a spherical shape. Sizes correspond with the depressions in the dapping block. The thickness or gauge of the metal determines which punch and die set you should use. Thinner gauges or sheet use a punch and die with similar diameters for a close fit. Thicker gauge metals require a larger die and a smaller punch to compensate for the metal thickness.

Metal thickness determines the punch and die size you should use to form sheet metal. For thin-gauge metals, a punch and die with similar diameters work best together for a close fit.

Thicker-gauge metals require a larger die and a smaller punch to compensate for the metal thickness.

When doming, work the metal into shape slowly. Starting with a larger or more shallow die and working your way down to the size you wish to end up with. Dont try to complete the dome in one step unless you need a very shallow curvature.

I prefer to use a brass dead-blow style mallet to strike the metal daps. Provides a soft dead weight that reduces bounce. Used for stamping, dapping and chasing and for hammering with disc cutters. You can safely deliver a good thwack to the daps when doming discs with a steel block without fear of damaging one of your good hammers.

Thanks Stacy, The information is great, for some reason the dapping tool has been a challenge for me, I just am not getting a comfort, but I am sure I will, I really appreciate the explanations and the help ALWAYS.

Thank you for this valuabla information. I am confused on one thing. You stated you must place a thin, soft protective barrier between the disc and the dimple. They are available in steel and bronze

Please tell me where I would find these barriers and what they are called.

This may sound dumb but please tell me exactly the parts to the dapping set up. What is the die? What is the dap? What is the punch? Tell me the procedure with the named parts please….

A dapping block or cube has dimples of varying sizes cut into it. These blocks can be wood, steel or brass. You can buy dapping sets which inlcude a dimpled dapping block and coordinating ball daps used to give metal shapes a convex or concave shape like a bead cap or half sphere. The different products available produce different results depending upon your jewelry design needs.

A simple small wooden dapping set has a block with more shallow dimples and not many size choices and just 2 ball daps. Metal sets have more of an arc to them (think half a sphere) and more size choices for creating large and small domed shapes. A metal disc is placed into a dapping block dimple and then he ball dap is placed on the disc and hit using a heavy hammer or mallet which drives the dap into the disc and forces the metal to form to the dimple shape. This is called dapping. Sometimes the holes or dimples in the cubes are referred to as dies.

Basically, using a dapping cube and daps to form metal into domed shapes is a type of die-forming also used to create shapes in sheet metal which is hammered or pressure forced into a depression. Below are some examples of dapping cubes and block sets.

A protective barrier could be a small square of chamois, paper towel or small pieces of toilet or Klenex-style tissue paper between the steel and your disc. This prevents the textured parts of your disc from coming into direct contact with either the steel block or dap.

Enameling 103 Metal Preparation

2013 Saul Bell Design Awardwinner,Nena Potts, crafted this lush and vibrant necklace using her considerable enameling skill. An inspiring example of whats possible with this fantastic technique!

We discussed safety and supplies inEnameling 101, and kiln firing vs. torch firing inEnameling 102. Now, lets get down to the hands-on process. This post will cover the importance of proper metal preparation for the enameling process.

Its important to have your metal clean and free of any contaminants such as oils, dust, fingerprints, or oxides prior to applying enamel. If you dont begin the enamel process with metal thats properly prepped and cleaned, all of your other planning could be in vain. Its possible to end up with enamel that wont adhere to the surface, or, after firing, might chip, crack and possibly pop off your work piece. Its kind of like trying to put makeup on a pig. Itll last a short time, but all the color will come off and youll be back to a dirty pig again.

When it comes to enameling there are several methods of preparation and cleaning. Some are more complex than others, but that doesnt necessarily make them better. Its important to select a method that will work with the piece youre creating and above all, one that youre most comfortable with. Regardless of your preference, the point is, do it right the first time!

Top: After annealing, dip your piece in pickle to clean the oxides off; Bottom: RiosHardwood Dapping Block and Punch Set

The first part of this process will be to prepare your metal by smoothing any rough edges. This can be done with aScotch-Brite™ pad, which also works great for scrubbing and texturizing metal. Next youll want to decide if you should dome your piece or leave it flat. This will be determined by your design; however, doming the metal will help to keep its shape and avoid warpage during the enameling process. A domed piece will also reflect light much better than a flat piece.

To dome the metal, youll first want to anneal it with a torch. Yes, annealing can be done in a kiln, but it takes longer because youll need to wait for the kiln to heat up and reach the correct temperature.

If youre working with copper, after annealing, quench in water, and then place inpickleto remove firescale. Once the pickle has cleaned the oxides off of the piece, remove withcopper tongsand rinse both sides thoroughly under running water so as not to leave any of the acid on the piece. The metal is now soft enough to be placed in awooden dapping block. You can now press down upon it with your fingers or a doming tool to generate a slight dome. (Not familiar with annealing? Heres a link to a greatAnnealing Metal videothat will help you to understand the process.)

If youre working with fine silver, theres really no need for annealing. The metal is already soft enough to put in a dapping block and dome slightly with your fingers or a doming tool.

Youre now ready to clean the metal and remove the oil and grease transferred from your fingers during the preparation process. You might wonder why the metal needs to be cleaned after its been heated, pickled, and rinsed. This is necessary because pickle only removes tarnish and oxides. It does not remove oil or grease and if you touch your piece during the sanding and doming process youll need to clean it prior to applying the enamel.

Take a Scotch-Brite™ pad and water, along with a cleaning agent likePam Easts PreNamel Surface Scrubor somepumice powdermade into slurry. (Pumice powder is a de-greasing agent and is great not only for cleaning a piece to be enameled, but also prepares metal for soldering, and helps to remove firescale. Its always a good idea to have some on hand.)

Scrub the metal on both sides in a circular motion until the water flows evenly across the surface. If the water beads up or pulls away from any part of the metal, then youll need to scrub again.

Once thoroughly clean, dry the metal using a clean, lint-free cloth. Be sure not to touch the surfaces with your fingers or youll have to clean it again. Hold the piece by the edges or with some tweezers to avoid re-contamination.

Left: Scrubbing in a circular motion with a Scotch-Brite™ pad to clean your metal; Right:Stainless Steel Straight Tweezers with Fiber-Grip Handles.

You can heat the copper with a torch, or in a kiln to burn off any grease or oil. If you work with atorch, set the piece on a tripod and begin heating under the piece keeping the flame moving. Soon, the copper will begin changing to a dark reddish-orange color. Within a very short period of time, as youre moving the torch, youll see the color begin changing to a greenish tone. Once the entire piece is this color, turn off the flame.

If working with akiln, pre-heat to the standard enameling temperature of approximately 1500. Once heated, set your piece on the kiln shelf and watch for the dark reddish-orange color change. This should take about 35 40 seconds. As soon as this happens, remove the hot item from the kiln with a spatula or kiln tweezers. While the piece is being removed, it should begin changing color to a greenish tone. If it doesnt change, place back into the kiln for just a few seconds. Watch closely to be sure you dont over-fire.

Either set the piece off to the side to cool, or usingtweezers, pick up the hot piece, and quench in water. When firing to green, theres no need to pickle the piece. However, if you over-fired to black, youll need to pickle, and then rinse both sides well under running water to remove the acid.

Dry the metal using a clean, lint-free cloth. Remember not to touch the surfaces of the piece or youll have to go back and start the process again.

Left to right: The copper changes color as it heats. It goes from a dark reddish-orange color to a color with a slightly-greenish tone and in the end its color is changed and its surface is grease-free.

Pre-heat the fine silver piece with a torch until it has a slight orange glow.

Watch carefully for the piece to look like its about to melt. At that point, pull back the flame of the torch where only the tip is heating the surface of the metal. Be sure to keep the flame moving over the piece in a circular motion until you see the entire surface of the metal become very shiny. Once this happens, immediately remove the flame and turn off your torch. This is known as flashing the surface. Use some caution with this technique. Too close with the flame and you will actually melt the piece, too far away and it wont flash. Flashing the fine silver not only helps to clean the piece, but also creates a polished looking surface visible through transparent enamels, which adds to the beauty of the piece.

Once the piece flashes, put it aside to cool. Be sure not to touch the surfaces.

On the left, a dull disc of non-flashed fine silver and on the right, a disc of polished-looking, flashed fine silver.

Follow the previously-described metal prepping process (anneal, pickle, and rinse your piece).

When youre ready to enamel, get some saliva on your clean thumb or finger, then rub the saliva over the surface of metal youre enameling. Once this is done, dont touch the surface. Saliva is a good neutralizer and works well to easily clean off the oil and grease after youve been handling the piece of metal. Please note, while this works great for small pieces, you wouldnt want to use this technique on large projects. It would be hard to create that much saliva for your piece, not to mentioneww!

This post, along withEnameling 101andEnameling 102, includes an explanation of all recommended supplies, except for theenamels. Now that you have an understanding of the prep and cleaning process, its time for the fun to begin! In my nextand finalpost, Enameling 104, Ill discuss the enamels and their application. Until then, if youre still questioning your ability to enamel, remember this

You dont have to be great to get started, but you do have to get started to be great. Zig Ziglar

Hi! How can I clean the enamel surface between firings from finger grease?Except fiberglass brush is there any other method to clean grease?Is it wrong to use denatured alcohol?

Thanks for the question! To clean the enamel surface between firings you can follow the process suggested under the Metal Cleaning Process, Method 3 Saliva or you can take standard isopropyl alcohol on a cotton ball and gently clean the enameled surface. If using alcohol, be sure to close the lid immediately after use and do not keep the container near a hot kiln or torch. We hope this helps!

Designing for Sheet Metal

About: Im a compulsively curious guy. I have taken things apart all my life, intrigued by how things work. I didnt know other tinkerers growing up, so Ive learned mostly by doing or through the internet. I hope …

What works on paper, doesnt always work in the physical world as planned, for a variety of reasons. What follows here are some of the various lessons I have learned while laying out sheet metal projects. Hopefully you can benefit from this guide and save yourself the time I spent learning things the hard way!

When youre making something out of paper, the thickness of the sheet is negligible–everything will line up and work out most likely in the end. Sheet metal is a different creature in this respect. Bends have radius, sheet has thickness, and tools need space to access a bend. When laying out a simple box with tabs, the tabs will meet the perpendicular face of the next side when folded up to 90 degrees, so when you are folding your tabs, measure in from the edge of the material the length of the tab, plus the radius of the bend, plus the thickness of the material for a perfect corner.When folding over a seamed edge, the folded-over portion is going to need to clear the adjacent faces on both sides. Slightly notching these helps resolve these issues. A file is sufficient for fine-tuning these bends.Think of bending sheet metal as what it really is: stretching one face, while shrinking the opposite face in a controlled way.

Welding sheet metal isnt always the ideal way to join sheet–especially thin or non-ferrous sheet. Heat causes metal to expand and warp if youre not careful. When spot welding, for instance, each spot weld causes the sheet to expand 360 degrees around the weld. If you start in the middle of the work and work your way out to edges, youll have more uniform results than moving from corner to corner.POP rivets are a good alternative to spot welds. Punch a dimple in the sheet metal before attempting to drill the pilot holes using an awl and mallet. Then, your bit has a depression to hollow out and wont stray and scratch the work. Put the rivet in the hole youve drilled, and draw the mandrel through the rivet shank with a riveting tool. You actually can dress these rivets as well. Doming them with a ball peen hammer helps a lot. Just be sure to use a steady hand, the appropriate size hammer, and a rivet set if possible. Solid rivets are another option, but doming them in tight spaces can be an issue, hence the choice of pop rivets for this box.If rivets arent your cup of tea, try brazing. Use a MAPP gas torch, brass brazing rods, and flux to heat the joint to braze and draw brass into the seam using capillary action.There are also methods of joining metal without fasteners or brazing. Hemmed seams are a good way to join two edges. Make a v-shaped channel on each end on opposite sides of the sheet, nest the openings and flatten closed. Clean up the seam with a groover–a steel stamp with a rectangular cut-out. Or, overlap tabbed-seams with a seamed edge.

If money is an issue, look no further than your closest alley. Cut the chassis off of a dryer, refrigerator, or filing cabinet. Cut down enough sheets that its worth the trouble to negotiate a price with a sand blaster in your town. Pay a fair rate to have the sheets sand or bead blasted down to bare metal. If youre really strapped for cash, use a belt sander. If the dumpster gods arent smiling upon you, try calling your citys trash collectors, inquire about large item pick-up day. Most towns have someone who breaks down appliances into recyclable materials, disposes of toxic things, etc. Ask for this contractors contact info and negotiate a price for the un-processed sheet metal.Sometimes your local steel yard will discount corroded material. Learn methods for removing rust and other types of oxidation. Ammonium works well on Aluminum Oxide. Sandpaper and stainless steel wire wheels work well on rust.

Sheet metal is sharp. You think youll be careful enough that gloves wont be necessary all the time, but youre wrong. I was wrong once and lost a weeks worth of work time. All it takes is one slip and youre out a few hundred dollars for stitches or surgery.

Adding a perpendicular face to a curved surface sounds like a daunting proposition, but with the right tools, its not such a big deal. The tool you want is called a Bead Roller. There are several companies that make them new now, Mittler Brothers Machine & Tool is the first that comes to mind, or several serviceable vintage machines are out there too, such as those made by Pexto and Roper Whitney. With the right combination of dies, you can roll that profile in 3-4 passes.

There are several different types of shears out there, and each of them have very specific uses. Trying to make straight cuts with a non-straight cut shear may lead you to believe that youre a crumby metalworker. Not true! Straight shears make straight cuts.Types of ShearsI. Tinners Snips:These are your grandpas tin snips. They are a very sturdy and useful tool, deadly accurate, easy to sharpen and maintain, and damned near indestructible.A. Straight Cut Tin Snips- Have a long, straight jaw. Used for straight line cutsB. Duck-bill Snips- Useful for cutting short straight sections and curvesC. Circle Snips- Used to cut circles of larger radiusD. Hawk-Bill Snips- Used to cut circles with smaller radius. Allows for added clearance in tight cuts.I. Compound Action Shears / Aviation Shears:used originally for making aircraft, these are easier to use because of their compound action, yielding a higher mechanical advantage. They are color-coded, though all you really have to do is look at the jaws and use your common sense. Yellow is straight, red is left, green is right. Long-cut aviation shears have the jaw angled 90 degrees from the handles and are good for making long, straight cuts where clearance of material is an issue.A. Straight Cut- Cut reasonably straight linesB. Left Cut- Make cuts that curve to the leftC. Right Cut- Make cuts that curve to the right

When you buy sheet metal it will have crisp, straight (on some axis) lines. Before you start laying out a project, take the time to check the edges for square. I use an aluminum T-Square for this. A carpenters square, machinsts square, etc. all work as well. This will save you from tearing out your hair after 4 hours worth of work when your project is 1/8 off center!Another option if youre buying your sheet metal from a specialized sheet metal supplier, they can cut the sheet on a squaring shear, a huge hydraulic monster machine that makes perfect cuts.

Theres a reason why sheet metal workers scribe lines, rather than mark them with a sharpie. While fine-line marker might do a fine job, a scribed line has a pin-pricks diameter and can be very accurate. A scratch awl or a divider are traditional and effective. A nail even works in a pinch. Scribe along a straight edge, or use your divider to drag along your squared edge to mark off distances from the edge.

If youre laying out a part with angled faces, for instance, to determine the lengths of the sides, you would have to use trigonometry. Are we metalworkers or mathematicians though? What I do is draft it out exactly. I know the base measurement, I know the angles, and I can draw the intersections. From there, set the distances from point-to-point with your divider, scribe onto the metal, and go from there. Its much faster for non-math types like myself. If you need to have tabbed-edges on a piece with these kinds of angles, divide the internal angle measurement by 2, mark it out on your draft, and go from there. Much easier!

Sheet metal in a flat sheet is not very sturdy. It can be bent, warped, and folded easily; thats why we love it! But when youre designing a sheet metal part, add a few strength-enhancing features to make sure your part lasts for generations.Hemsare created when you fold over the metal back onto itself. It saves time (less de-burring), gives a more finished look to your edges, and, most importantly, it adds tremendous amounts of strength to a face!Beadsare embossed lines that run across the surface of the sheet. These are made using a bead roller. These indentations add strength perpendicular to the bead. This is the idea behind corrugated tin roofing.Grooved Seamsare a great way to join two pieces of sheet metal, but they also create tremendous strength perpendicular to the joint. A properly grooved hem has 2 broken edges, and 4 layers of sheet metal in one spot. Very strong!

If you need to break small edges that are difficult to access, try using a hand seamer. These are designed for HVAC work, but work very well for making finger-break type work without the proper break. Fold the part over in the hand seamers jaws, use a mallet to sharpen the edge, and release. These can be used to break long, continuous edges as well, but in 3-4 steps, working uniformly across the surface. I use them to finish hems.

Please be positive and constructive.

Ive been a sheet metal worker for close to 20 years now. Went from old school techniques to modern equipment. This is a GREAT instructable. Very well done.

Nice and useful instructable! Thanks 🙂

Hi iwant to make a small working boat model with thin sheet metal can i glue it with araldite or is there any way to make joint watertight without welding or rivets

I am not familiar with araldite, but you could do a grooved flat lock seam and silicone it from the inside. If youre trying to make the keel joint where the two hulls meet, you may be able to form this from a single sheet rather than seaming it.

Heat it to anneal the sheet. Use a blunt v-shaped die over a wooden form or sandbag to begin to stretch a ridge in the sheet. Anneal often. Use a ball peen hammer and work out from the keel and up the hulls and raise the radius into the sides. Trim flush with a pair of snips and clean up on a disc sander. Copper would work best, and youll want the sheet to be a little thicker than your finished piece.

You could roll a hem on a rotary machine. Thats how soda cans are made (kind of) and theyre water tight.

You could also form a keel seem from a 90-120 degree bend on a sheet break. Draw the arc you want for the hull, transfer it to both sides, Cut away the excess on one side, cut away all but a 1/4 tab on the other side, then epoxy the tab to the opposite side. Silicone the inside.

That said, you could also just learn to solder. Its way easier than forming sheet stock manually like this. Happy tinkering!

I wouldnt even try to weld galvanized metal, unless you want zinc poisoning haha.

pretty cool Bro , I learned more than a few things , well done man !

A thick Sharpie line before you scribe can help make the scribe line much more visible, though, and you can use different colours for bend, cut, etc. Excellent instructable, thanks!

Great instructable! Watchoutn when using HF hand seamer, I squeezed mine a too tight and broke it in half. I kept the bits to make a sand casting with in order to make a real Made in America tool in my home founfry.

Thanks! Most HF tools leave a lot to be desired in terms of durability. Id love to barter for a home-cast hand seamer if youre casting some!

Very nice instructible, brought me back to a better day. As does just thinking about the glorious sheets of 060 stainless steel (with the edges so dul, gloves were merely a fashion statement) and 12 foot skids of clad and unclad aluminum stacked 15 + feet high, with brown paper sandwiched betwixt every sheet. Oh yes, those were the good old days and now that youve mentioned it, theres no reason they cant be relived a bit for old timers sake. Thank you for this. One question; Ive a pair of straight tin snips that need to be sharpened and perhaps tightened up, what type of edge should they have and how tight should they be etc. I think you are the person to ask. (if the good old days were still here Id have a brand new pair)

My shears all have a single bevel edge that I touch up with files. Im not sure of the angle. As for the tightness of the shear, there are many styles with their own specific tightnesses. My recommendation would be to pick up a set of thickness gauges like machinists use. Slide them into the joint on a pair that feels good to you and adjust accordingly. Happy metal working!

While this is a great instructables, theres two small thing I could suggest to help you improve it.

1. The scratch awl is a good idea to precisely trace a flat pattern on sheet metal, BUT I would not recommend using this method for any structural component. The reason is simple, you are adding weak spots all over the place,and they will sooner or later result in fractures.

2. You probably did this for the convenience of it when cutting your metal, but the sharp corners on your flange near the bending lines are also weak spots waiting to transform in fractures. You can easily drill a small hole in those corners before cutting the metal with your snip to create small radiuses that will help increase toughness.

looks like the engineers toolbox (i know its not, its an older design of a toolbox)

Thank you for a very fine, useful Instructable. I am thankful to have a welder, but find there are times when my pop rivet gun is the better choice. As regards free metal, we recently replaced a water heater. The old one is full of lime and heavy. I am cutting it up in pieces before trying to haul it up the basement stairs. The outer shell is a nice gauge of sheet steel I want to use for various projects, including some small parts trays. I hope your Instructable is featured and makes the newsletter.

Thanks! To make that outer shell lay flat, you can cross break the sheet using a break press. Make an X across the sheet, then a box around the perimeter and it will lay flat.

Nice intro into becoming a diy tin knocker, thanks.

I have been thinking about making a small brake and trying my hand at it.

If you just want to get a feel for sheet metal without a huge investment, there are tool called bar folders which are basically a hinge that bolts to a surface with a machined-flat piece of bar stock that you clamp over the material you want to bend. Bend the piece up to the desired angle. Harbor Freight has one for $40:

This is a great intro to working with sheet metal! I learned a ton.
