7 Layer Cake

My baking skills are not good enough for me to do this on my own, but I'd love to see an Instructable on making a traditional 7 Layer Cake. I was surprised to find it in the supermarket freezer the other day and wished I knew how to make it (at least in theory). It is usually only found somewhere where there is a large Jewish or Eastern European influence and there seems to be fewer and fewer bakeries making it so I'd love to have a recipe for posterity should I ever be inclined to give it a try. It was the first time I've seen it in California (and it was shipped from a bakery in Brooklyn no less!).

My First 5-Layer Gun, need help

I'm gonna post my first 5-layer gun soon, but I'm having an issue. I can shoot a rod fine, but since the barrel is the perfect height for a connector, and since my gun is kinda long, the ramrod "isn't long enough" to shoot out connector ammo. Please help. :)

Software for slicing 3d model into layers for printing, cutting and assembly from card, layer by layer

I've been looking for software to slice up some 3d models I've made in 3ds max, and i know there are Pepakura model unfolders but the shapes are quite curved and a pepakura model wouldn't shape up right. So I'm looking for software that can cut a 3d model into variable layer height for printing on card and assembling like a 3d sculpture ( see Darth Vader - http://www.flickr.com/photos/ciberdoc/3895118480/ ). Any ideas?

Why a hole in the Ozone?

So I have been looking up a little bit about the ozone layer and have found that about 12% of the ozone layer is reproduced by UV rays every day.  So the whole thing is replaced in about 8.3 days.  Now I think thats a little bit shorter time-span than since we stopped our mass release of refrigerants into the air.  It has even had a bit of time to catch up.  Now if you think about it, less ozone = more UV = more ozone right?  So how On earth did we blow a hole in our ozone layer, it makes absolutely no sense.  Even the fact that some of the halocarbons may still be there makes no sense because it absolutely could not affect the ozone without reacting with it.

Layers V.S. Length; Electromagnets ? Answered

Ok, so I am going to be working on a project that involves electromagnets and the on thing I have never gotten straight is this: To make the most effective magnetic field possible do I make the (hypothetically) 100' of wire a long coil with only a couple of layers or 100' of wire a short coil with many layers? I have always come across conflicting views on if length improve the fields or weaken them. Any insight would be helpful and if you could also provide a good reference site for these types of questions that would also be appreciated.

Failed Three-Layered Gun

People don't often post 3-layered guns, so I thought I would try one, and (as you can see by the title) it did not turn out so well. It got maybe 40 ft. of range, but that was an accented, as the gun never shot again. It was a good attempt, and is not too ugly, but, it is still a failed project. I just thought I would share it with you guys. Keep an eye out for more projects from me! -E Pluribus Unum

Joining Aluminum Sheets in Layers?

I need to join aluminum sheets together. When I say sheet, all I mean is the body of a coke can. So, I would cut the top and bottom of the can off, then make a vertical cut to make the body into one long strip. I would do this again, and then I want to join these two strips together, end to end. Would 1/8" rivets work? I thought of solder, but I heard solder doesn't stick well to aluminum. I would prefer the aluminum to stay down. Does anyone have any ideas? Thanks!

Smoothing the rough surface

Hello everyone. My name is Thomas and I am very new to this 3D scene but still very glad to be here. I would like an input from everyone about something. Recently I purchased MakerBot printer and printed something simple. At first glance I was amazed by the finished product. I'm sure you've felt the same way. But on a closer observation and physically picking up the object, I realized that the outer surface was rough (or more like layered). Now my question is what is your solution to this rough surface? I tried sanding to smooth it out. But I'm pretty sure there's a much starter way to tackle this problem. Thank you have let's make something!

Update on the layered metal weapons/props

Hello to everyone who took the time to read this update/list. So I have not forgotten about my promise to upload the Solidworks files and cutting plans. However that will be taking a backseat to finals until summer break. I will however go ahead and list off the items finished, in progress, on hold, or currently only in Solidworks form. Finished -6in Axe: 3lb head on an oak clad 1/4in steel flat bar about 20in long total -3in Tomahawk/Axe: 1.25lb head on a para cord wrapped 1/4in steel flat bar about 20in long total -27in BoneSplitter: 3.2lb aluminium reinforced steel construction. -18in BoneCracker: 2lb aluminium reinforced steel construction. -18in All steel BoneCracker: 3.5lb steel reinforced steel construction. More square handle and better center of balance than previous version In progress -10in Bearded Axe: 3.25lb head. To be mounted on oak clad 1/4in steel flat bar handles 18in, and 30in long. -10in blade Pugio: Model made of mild steel for practice and training. Needs to have bevels, and fullers ground plus handle and guard mounted. -8in blade Pugio: Model made of mild steel for practice and training. Needs to have concave edges, bevels, and fullers ground plus and guard mounted. On hold -14in Blade tester: Simple test bed modeled after BoneSplitter to test viability of various band saw blades(Metal and Wood cutting) for use as cutting edge for mild steel blade carriers. On hold due to the band saw blades being too hard to drill through. Only existing as Solidworks files --27in Revised BoneSplitter: 4.5lb Aluminium reinforced steel construction. Better center of mass and more square handle than MY           previous version. --37in blade Bastard sword: Aluminium reinforced steel construction. Should be very close in terms of center of balance and stiffness when compared to its hardened steel companions.  --20in blade Stacked steel Gladius: Twin riveted steel support plates with detoothed metal cutting bands saw blade used for striking edges.  --blade Hispaniensis Gladius: Single piece of metal for the blade. --blade Cinquedea: Single piece of metal for blade. Multi fuller blade. --8in blade Pugio curved: Same as other 8in Pugio except for the convex curved dagger tip --14in blade Spear from Fullmetal Alchemist: May upload the variant of this in which the "wings" are separate pieces of metal. --3.25in square Warhammer: 8.5lb head Assembled from 13 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --5.25 square Warhammer: 16.25lb head Assembled from 21 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --Straight edged War Axe: 7lb head Inspired by Ironclad Industries' Riftclaw. Made from 7 1/4in steel plates pinned together. I am aware that the riveted and pinned construction of these items makes them inherently less durable and less corrosion resistant than single piece construction. However I am a college student who is working with mostly scraps and whatever has to be purchased. Since mild steel thick enough to carve the Warhammers or War Axe is not common scrap material around the college's machine shop the only way to economically create them is to use stacked plate construction. As for the BoneSplitter, BoneCracker, and Bastard sword the stacked plate construction is used to both reduce the weight of the item and stiffen it at the same time.

How to remove the copper layer/film from a PCB ???

Hi ... do you know, how to remove the copper layer from a PCB - by not using any ETCHING METHOD. Just to separate the cooper from plastic/f.glass ??? Do you think, that HEAT would do the trick ??? Like when you hold soldering tip to long on a pcb, it can happen that the cooper film become loose from the PCB. Thank you in advance. Zholy P.S. : The reason, why I asked = I was thinking of creating/extending a "ribbon cable" : 1. remove the copper film 2. stick it to the foil, that you can laminate 3. put the "ribbon cable pattern" on the film and ETCH it. 4. laminate it ... and cut the just the top of the laminate foil at the ends, so you have clear cooper for the contacts, but the bottom laminate film as a support.

Will layering chrome vinyl wrap leave "seems" on the finished product?

I'm making helmets that will require a mirror-like chrome finish. I've done a bit of looking, and have found spray paint (wont work, as the mirror finish is not there), actual chroming (WAY too pricey for me), or vinyl wrap.  From everything I have seen, this [chrome vinyl wrap] will work wonderfully. However, the issues is that I do not know if I will have "seems" when/if I layer the vinyl. I'm sure I can avoid having to put seems on the helmets, but I would like to have my bases covered before I spend the money on the wrap itself. Also, on a related side note: will it [vinyl wrap] chip if applied to a car? I have another project that would require a decent chunk of vinyl wrapping on my car, and again, I would like to know everything before spending the money. thanks in advance!

preventing buildup of glutinous substance on duct walls?

During a manufacturing process, hot air flows through a duct carrying fine particles of a glutinous substance. With time, those particles stick to the walls of the duct and create a thick layer on them. This layer reduces the cross-section area of the duct, changing the velocity of the flow. To remove this layer, the flow has to be stopped. Any ideas of how to remove the layer without having to stop the flow? Or to prevent the buildup of the layer?

Would layers of microfiber cloth work as an effective N95 air filter substitute?

Hello, as many of you know, there are some devastating fires in California right now. My family and friends live nearby to these fires, and are being exposed to toxic levels of smoke and air pollution. Due to the disaster situation, many stores that sell n95 masks have sold out or are price gouging people who need them. I have been trying to figure out an effective solution where they could use household materials to approximate the particulate filtering properties of the n95 filter. I was thinking they could make some kind of respirator style mask with the main face mask made of cardboard and duct tape, ad make a "cartridge" for the mask out of a cardboard cylinder stuffed with layers of microfiber cleaning cloth, or potentially other air filtering material, or even activated charcoal if it is available.I understand that such filters are not an ideal substitute but when the air is completely off the scale for toxicity, anything is better than nothing. Does anyone have any input on this? Is this worthwhile at all? Is there another commonly available material that you would reccomend other than microfiber cleaning cloths? -ilpug

Home to get layers of old plastic contact paper off of sheet metal?

Hi! I bought this old sink at a salvage yard.  It has a sheet metal bottom with some drawers and cabinets. They are lined on the inside with this plastic contact paper that's been stuck on for 50 years. I have tried getting it off by applying extreme elbow grease and a metal paint scraper, after soaking the surfaces for a while in this stuff: http://www.wmbarr.com/product.aspx?catid=36&prodid;=155 ("Cirtistrip Low V.O.C. Adhesive Remover") but its still pretty much not coming off. Anyone have a better idea about how to get this stuff off? A greener, not-so-toxic method would be great... but I'm not sure if there is such a thing? (FWIW: The sheet metal is not bare, it has a white paint/enamel-type coating.  Which is pretty scratched up in places.  I intend to sand & repaint it, once I get the contact pager off.)

DIY Furniture: I have two rectangles of fiberglass with holes drilled in the corners. I want to make a coffee table.

I want to create a two layer coffee table. I've got the idea in my head, but haven't found the right materials. The fiberglass layers both have 4 holes (approximately 3/8" diameter - I can be more exact if necessary) drilled in each corners. The two layers would be separated by 4 metal tubes/pipes (~ 18"?) made of stainless steel or brushed nickel or the like. The top layer is held onto the 4 tubes by some sort of screw with a flat head that's bigger than the hole diameter. The bottom layer is held on by some sort of furniture "feet" that screw into the tube from the opposite side. Any ideas on what I can use for the top screw, the tube, and the foot? One such assembly for each corner, of course. The more exact the answer the better. Thank you, Chris

Can this work for DIY 3d metal printing at home?

Using metallurgical powders with a precision depositing feeder, layout a layer at a time (obviously) of the part you want to develop within a certain size parameter.  Lower the layer into an induction heater coil to raise the temperature of the powder to just below the melting point then hit it with a low power laser to melt the powder together to make the part, again layer by layer.  Theoretically removing the need for high power lasers and either a vacuum chamber running constantly or a constant stream of shielding gas.  Edit: You apply a vacuum or shielding gas only during the fusion cycle, hence the induction furnace. Removes the need for expensive vacuum chambers or heavy use of shielding.
