In order for the "tines" on your comb to ring brightly, you must begin with spring steel. You may use a flat piece of steel and cut the teeth into it or use a long length of quality steel bar such as a metal yard rake. I used a length of sewer cleaning flat bar--cheap and very good steel. I simply cut it into 15 pieces about 3 1/2" long. You ...

You won't notice a lot of differences between using vine and willow charcoal. Vine (of the grape) tends to be slightly darker in tone, is physically a little harder than willow, and I believe it has a somewhat finer structure. Vine is thinner and usually a little straighter than willow. The latter can come in a larger variety of thicknesses, which can be ...

Balsa wood is likely to provide the best strength versus weight ratio of any building material you'll find. Peter Sripol recently posted a YouTube video of his construction, a rigid airship. Pipe cleaners contain a metal spine adding too much weight, in my opinion. You may want to consider to use thin lines for suspending the gondola. Spectra fishing line is ...

Kite string is a product. It is designed to be strong and light to enable kites to fly under optimum conditions. For ordinary kites, ordinary kite string is sufficient. High performance kites (large lift capability, stunt/performing kites) require higher breaking strength while retaining light weight. Spectra line is constructed of high density polyethylene ...

The mats are common, as you suggest and are composed of EVA foam. Almost every source I've found involves textured surfaces and interlocking edges. This is not universal. Cosplay costume makers use this material for creating various components of costumes, including masks and armor. My brief search returned un-textured foam in 0.25" thickness (6.35 mm) ...

Do you want the shirt to actually be wearable? If so, then "synthetic resin varnish" is entirely the wrong option. For wearable clothing, you need a color that bonds with the fibers to endure wear and washing, but also remains soft to allow for comfortable wear. The best option for something like this would be a standard acrylic paint with a high ...

You will find a number of kite forums on the internet. Common to many is the consideration that one does not fly in areas known to have substantial air traffic. This includes airports and hang gliding (and paragliding) sites. Adding tails/ribbons to the line will not increase appreciably the visibility of the kite line to pilots, but it will increase the ...

To really mimic that sound experience, I'd recommend using multiple small pieces of something in the cavity. A single piece would have to bump against its enclosure to make a sound, but many objects inside will produce noise against each other as well as the enclosure. (While a single Kodama may actually produce only a small rattle on its own, I rather like ...

The obvious solution seems like the best here. Sew it on by hand. This requires basically no sewing experience; if you can sew on a button you can do this. Don't put the needle through the wire. Rather, put the needle through the fabric from behind, wrap it over the wire, and put it back through the fabric on the other side. This makes a loop of thread over ...

There does not seem to be a specific name for this exact type of hardware. It is referred to generically as a "push button catch" or "push button latch". I found a number of examples on small boxes like jewelry boxes and ring boxes; some were all brass and some had buttons of other materials. All of the examples I found were identified ...

For your objective, spill-resistant and ding resistant, you're dealing with two parameters that could be combined. As noted in Bill Horvath's answer, the weight will be a factor. Cardboard for concrete forms is pretty durable and somewhat moisture resistant "out of the box", and could take mild abuse without modification. Virtually any paint will ...

There are still a couple of ambiguities in the description, so I'll try to cover a few variations on what you've described, including a possible alternate approach. Resin casting as the "finished" item The question describes the objective of making a small box, similar to a ring box, that will be lined internally. The scenario I'll describe in ...

The terminology varies from "industry" to "industry" but the concepts are the same. I watched years ago a video teaching creation of molds from fiberglass cloth. The original was called a plug, the mold was created from the plug and the part was created from the mold. In jewelry casting, the concept is the same, but the words are ...

There are several ways to repair, one of the easiest would be to use book repair tape. There are several different ones available through Dick Blick. Two that I have used in the past and have worked well are Lineco Spine Repair Tape and 3M Scotch #845 Book Tape. The first is basically a cloth tape available in both black and white. The 3M tape is a thick, ...

You can use a layered option. Frosted acrylic or polycarbonate tends to be expensive, so you can get a thin sheet of that, maybe 1/4" or 1/8", then get a clear support piece the same size but thicker as your base. You don't need to glue them together, or anything, just lay the frosted piece over the clear. In fact, I've done a fair bit of gluing/...

THE BRUSHES Animal hair While it will be hard (or unethical) to come by kolinsky, wolf, red sable, or even badger or squirrel hair, some types of hair that are appropriate for watercolouring can be acquired more easily: Boar bristles (taken from the ears of hogs) are commonly associated with acrylic and oil paint use, as they are very coarse and not ...

If the ribbon is polyester or nylon, it will be hard to make a strong bond to it. Most adhesives will stick a ribbon to something if it's only decorative and won't really get pulled. You need something more secure if the ribbon is going to serve as a hinge or closure. If you can use a ribbon made from cotton, lots of glues will make a strong bond. Even ...

Your problem is the opacity of most fabric paints; most liquid ones are only designed to work effectively on a white or light-colored shirt, and the thick plasticky "puffy paint" writers aren't going to be effective over large areas or in stencils. If you're working with just white, opaque white screen printing ink for fabric works very well. It ...

Limitations If you're talking about any kind of piloted aircraft, the human eye is pretty limited in seeing small/thin objects from a distance, especially while moving and focusing on more distant objects, like the ground, or huge structures like mountains, roads, or buildings. Moving at high speed, the aircraft also can't turn on a dime to avoid a line ...

Paper has the habit of becoming wavy when wet with water (other liquids too). So the first thing you might want to try is ti use a non-watery glue, but still suitable for paper. For the next projects, you might want to investigate about the types of paper available, to choose one more suitable for what you intend to do. During curing, make sure to apply ...

I'm not sure we're all actually referring to the same properties. Let me start with some definitions. Transparency refers to light passing through the material without being diffused or scattered. If the material is transparent, you can change its color but still see undistorted detail. Think "looking at the world through rose-colored glasses". ...

You can make your own sketchbook ring binder: That way, new blank A3 pages, as well as coloured index tabs, can easily be added anywhere. You can perforate new pages yourself using a hole puncher. If your project files consist of a lot of loose or thick objects, you can also opt for a binder box.

Add a mesh/grid of thin tensioned horizontal wires below the sheet - your frame will need to be strong enough to resist the tension. Something like guitar wire, or perhaps clear fishing line will have minimal impact on the image projected - though do a test before committing.

Damage to the leather is just like any other detail. It is created by relief (changes in height) in the surface, so it is rendered the same. Just like the embossed areas of the leather, one side of the impression will capture light and the other will cast shadow. So to draw scratches etc., you would use light edges and dark edges along the contour of the ...

You can use something thick and rigid enough to not noticeably sag (like glass or thick plastic). But you can also accomplish it with relatively thin material. The material will bend but needs to be stiff so as to not sag in random places. Giving it an intentional slight curve in one direction will prevent it from bending in the other direction. Make the ...

For your current painting assemblage there is very little you can do. The paints will have warped the paper, and the glue might have done the same. You can glue the piece unto hardboard or another rigid surface (using, like virolino mentioned, a non-aqueous glue, such as glue-sticks, like Pritt's - be careful not to get too close to the paints, though, or ...
