  • Creating a Costume/Cosplay From E.V.A Foam

    As far as scissors are concerned, use the heavier-weight Chinese shears, rather than dress-making scissors. They're easy to sharpen by hand, as long as you work from the top of the blade towards the edge: don't use cheap sharpening steels because if you bevel the cutting faces, they'll stop working so well. Effectively a scissors works by leverage, the faces of the blades meet on a flat surface, allowing nowhere for the material in between to go other than to separate in a cut. You need to protect that surface, so you sharpen towards it, not away from it or into it - any sharpening removes a very small amount of the tool material.

    Cheaper still when it comes to chipping, use flour paste: it absorbs the paint better, and really is dirt cheap - just add a drop of water to flour and roll it into a thick paste. Mustard's actually just a more expensive kind of crushed grain.

    Upgrading 3D Printer From 12 to 24 Volt

    Actually, remember the old adage, it's the volts that jolt, but the amps which cramp. One of the secondary benefits of AC (the primary being far lower attenuation in distribution) is that AC throws staying hands off, and the higher the voltage,, the stonger the kick - you may have a pulled or torn muscle, but you'll suurvive. It's the amps involved which do the cooking, the cellular damage to your core.

    Leather Embossing With a 3D Printer!

    Damping the leather down opens the grain so it'll hold the stamp pattern when it dries. That ONLY works with veg tanned leather, it does NOT work with chrome tans - and if it doesn't say, test it with a drop of water - you will see a serious darkening where the water's taken it in. Don't worry, it'll evapourate and the leather then returns to a normal colour.And soon you'll discover the world of shaders and veiners, and all of the weird and wonderful takes on Victorian aspidistras...and stains to darker the hollows, and highlighters, and your workbench ends up looking like the missus' makeup bag, just a tad gentler. I swear she keeps a mallet around there somewhere...

    Playboy Bunny - Full Costume

    For large pompoms, the weight can get rather excessive for the wool used ib the anchoring loop, which is why it keeps coming loose. It may be a better plan to use light nylon cord in the same colour (white) for that, instead of wool, and to braid it up before cutting the circles free. That then gives you something far more substantial to sew onto the main work, in this case the suit.To do that, use two separate strands around the body of the wool in the centre of the cardboard circles. That then gives you four cord strands to the outside, which you can braid into a flat ribbon - just make certain the ends are quite long, so use cords up to ten times the radius of the ball, as braiding eats up thread. If you've used a nylon polyester cord, heat-seal the ends using an old knife blade heat...

That then gives you four cord strands to the outside, which you can braid into a flat ribbon - just make certain the ends are quite long, so use cords up to ten times the radius of the ball, as braiding eats up thread. If you've used a nylon polyester cord, heat-seal the ends using an old knife blade heated in a flame (I keep one just for this, it's a work of art all of itself, there are so many colours annealed into the blade), and sew to the costume.To braid with four threads, simply lay them flat, and take the left one and weave it over-under-over to the tight hand side. Repeat until you have enough length. If you want to be really pernickety (it's not necessary here) you start with a half-weave, lifting the third over the fourth first, and finish similarly, with the first just passing over the second. When you cut the ends short, the knife melts the nylon, so encourage the melted plastic into a solid line across the braid, to really hold everything in place. The knife doesn't actually have to be that hot, in fact, you get a better finish from one which is just knife-through-butter rather than something glowing cherry-red.

  • Custom Full-ear Silicone Earpieces Via the Magic of Sugru!

    Another approach is the more classic 3-stager, using Shapelock to mould the outer ear, which is then machined to fit the plug. It's hard, though, so form a negative mould from the old-style mix of talc avd silicove, avd finally go for the final mould in Sugru from that. It also gives you several goes from one moulding

    Don't forget a lot of the firearm sound is percussive blast rather than true sound, so it also travels along bone, circumventing the plugs, which may even make it worse. This is why we use softer foam.

    Horse Tail Tutorial

    As a member of the International Guild of Knot Tyers, I'd recommend unlaying that rope being careful not to release the twist in each chord - just lift it away. That way you can lay it back together again so the metal's buried in the centre of the rope.

    Articulated Wing Framework

    JFDI as told. What you wear under the pack frame is up to you, the torsion on the frame from that weight and distance may be considerable, and break spine spurs if carried directly on the bones as a corset does, causing permanent disaility.

    Stitching or contact cement - or both

    Seven Archangels, Michael, Raphael, Gabriel, Uriel, Saraqael, Raguel, and RemielAdd a tensor stop within the wing an inch or so below one hinge to limit it's spread. All you need is to screw a short piece of elastic to limit the throw, or wire and a catch.
