A primer on picking

So, judging by what I've seen so far, a lot of people have a terrible concept as far as lockpicking goes. They don't know if it's legal, if it's really possible, etc. As such, let me begin by saying the very first thing you should do if you're interested in picking is go somewhere else. I don't intend to give you a full tutorial about how to pick. You can find that online in a lot of places. A good idea is to subscribe to a forum of experienced locksmiths and search there for a while. One I highly recommend is lockpicking101.com. Picking is a fun, albeit expensive hobby. It's also a living, or part of a living for a lot of people. I am not the devil for advocating lockpicking. Believe me, if someone wanted in your house to take your stuff or to cause you harm, they'd be more likely to go through a window than to take the time to pick a lock. I am not making the world any more, or less, secure with the information I post here. Owning picking tools is not illegal pretty much anywhere in the continental US, except maybe in Washington, D.C. Picking a lock you don't have a right to is illegal, and immoral, everywhere. It really can't be said enough: NEVER PICK A LOCK THAT DOESN'T BELONG TO YOU OR THAT YOU DON'T HAVE PERMISSION TO.

Sculptural Crochet Primer

Here SuperNaturale features a curiosity cabinet of crochet figures, thus illustrating the basic elements which combine to form sculptural crochet.Much like a traditional Wunderkammer, the pieces are divided into subgroups, each of which explores a certain variable.I'm struck by the beauty obtained by using simple stitches and one color to make a striking, strangely biologically-evocative piece of artcraft. It's obviously left me with a loss for words.

painting an old table top?

Hello people :) ,  im in the process of painting a table top., ive sanded the top (Lightly) and put an all purpose primer on top, but ive run into a spot of bother, let me explain further. the table top i have detaches from the legs, which bis handy, now looking underneath it, it is painted black, but i can see that it is real wood underneath (i can see and feel grain and knots) BUT on top it seems to be a different wood or covered in something different on top of this, there and rectangles of veneer - which the primer seems to adhere to ok, but the darker part of it dose not seem to pass the fingernail test, so it may  not be the right primer, but im stumped as to what primer i would need, sanding didn't seems to make much of a difference to the dark wood barely dull it really, and im not sure its laminate or some sort of plastic... ive added a picture of the table

Can I use rustoleum epoxy "appliance" spray paint with rustoleum primer?

I'm refinishing my steel medicine cabinet. Its old and a little rusty in spots, so I sanded it smooth and removed as much rust/old paint as I could. I washed it down, let it dry and gave it two coats of Rustoleum "rusted metal" primer in the can. I also purchased a few cans of Rustoleum Appliance Epoxy Spray paint. However, I didn't note that in the instructions, it says "priming is not recommended".  I already have the cabinet primed and ready for paint at this point and would like some imput on putting this epoxy over the primer.

How do primers in ammo work? What are they made of?

Anyone here know a thing or two about gun ammo? Anyway, I have just been wondering on exactly how primers worked. This is how I made mine. "Sorry if I seem like a lot of questions) The Cartriage is a section of a copper pipe, the bullet is made from a fishing weight, the propellant is match powder. Since match powder does not go off with impact,I made the primer from a thumbtack, a strip of tin(can), and a roll cap(those red paper things that explode when you hit them with a hammer). The cap and the match powder hold the thumb tack in place. The strip of tin holds the roll cap. When the thumbtack is struck, the thumtack hits the roll cap cuasing it to create a small explosion. When the roll cap explodes, it ignites the match powder around it. This larger secondary explosion is the one that propells the bullet forward. It works on homemade automatics, the only thing is that the catriage gets stuck sometimes, it produces A LOT of smoke, it takes around a half a second for the match powder to ignite and to propel the bullet forward, and after a while, a layer smelly brown tar begins to accumulate in the barrel. Is this a bit simmilar to how primers work?

Deadmau5 head with plastic / wood / fiberglass ears? Do I need to mold them using body filler and glass fiber?

I'm going to use deadmau5's cheese head as it is visibly the best for an example. The ears are made of a hardened material with a gloss finish. The holes through them seem to clearly show that they are not foam underneath. I was curious as to how I could achieve the same effect and strength. I've seem some exquisite models of helmets here and in particular individuals who have created the daft punk helmets. They created molds. I've never used fiberglass / body filler / etc but I'm a rapid learner and I'm willing to suffer trial and error like anyone else. I was curious though, if it is possible to take the styrofoam ear and then coat the ear with bondo (or another body filler/putty) to create that hardened mold and then primer, paint and gloss it. Can someone with experience with these materials shed some light. I really want to achieve this look! Here is a video of the cheese head when it was unveiled: Thanks in advance guys. I can be contacted via email at "sip_deco_c@hotmail.com" if required. Help would be greatly appreciated! Peace, Deco

What's the best way to sand and spray paint particle board?

Hi All, Trying to make replacement bases for my floor-standing speakers.  The originals were made out of particle board and appear to have a black spray-paint finish.  They were destroyed in the post when the person sending me the speakers failed to package them properly.  I now have the particle board cut to the right shape and I have begun the process of sanding.  It is my intention to spray a primer on, sand, spray a top coat, and then spray some sort of finish.  so here are my questions: (1) I have sanded the board down with successively finer sandpaper and finished with 1500 grit wet and dry.  This is a very smooth finish until you wipe away the dust at which point it becomes rough-ish again.  Having done a bit of research I am now concerned that I have sanded the board down a bit to much, some forums suggest taking the board down only as far as 250 grit before spraying on the primer.  What should be my finishing grit before spraying on the primer?  My assumption was the finer the better but I'm not too sure now.  If the finish should be fine then how do I remove those stubborn fibers? (2) what type of spray primer works best with particle board?  There seems to be a multitude but most of the information related to car/auto body work.   (3) what grit of paper should I use on the primer? (4) what should I use as a top coat? Much thanks in advance Ross

PVC pipes and winding Tesla coils....

There are still people out there playing with high voltage.And one big problem when it comes to Tesla coils is winding the secondary coil.Now, I won't go into the details and options of the actual winding part, instead I would like to share some tricks that might make things easier for your project.Whether you wind fully by hand or make use of some mechanical winder, magnet wire is a very slippery thing on PVC.For that reason and some others we usually wind as tight and close as possible.Any leftover spaces that you find after the winding is finnished will severly compromise the overall tension of the wire in this region if fixed.Next problem is what many call aging.No matter how good you coat your coil with varnish or paint it will start to degrade over time.I found a simple fix for these problems :)Well, not really that simple but I am too lazy today to make a full Instructable for just an addition that everyone can make in a few minutes....Let me start with idea behind it all:I noticed that no matter how thick the pipe or wire is that there is little to no chance at all to get any of the coating material through the wire and all the way down to the PVC.One coil failed after I abused it so I did some cuts and had a close look with a magnifying glass.The coil itself was really good covered but it was like a sleeve that sits on the PVC with nothing on the underside of the wire except for a few single spots.Some people will now say to just a much thinner mix for the coating to allow the stuff to sweep through but that does not always work.One big issue I noticed is that not all paints or varnishes actually stick to PVC.Especially those non smelling eco friendly ones most places now sell.This means when the coil expands due to the vibrations and heat the wire can simply rattle off the varnish or the coating itself can crack under the stress.So I thought there must be a way to fix this right at the winding stage....PVC is a good insulator too!So why not use PVC instead of messing with other things?My first attempt here works quite well with thin wire and goes like this:Go outside with your winding rig and have a bottle of PVC primer and a little brush or sponge ready as well as some gloves.If you have use a friend, if you have none make a small rig to hold the sponge right in front of your winding area.The key is to keep the sponge wet with the primer so it will wet the pipe properly.Best is to have the speed and distance set so the surface just starts to dry off under the wire.The primer will cause the PVC to soften, so the wire slightly sinks into the surface.An automatic winding rig is best here as it allows for consistency.There is no too much or too little here is nothing drips terribly and your wire sticks without fully sinking in.Once done you can cover the winding with your prefered coating.For thicker wire, lets say 0.3mm or thicker, I now use a similar way but with more preperations:Using some very rough sandpaper on a belt or vibrating sander I create a small pile of PVC dust.If you prefer some fancy color you can use ABS plasic here too and it dissolves in a similar way.The resulting mix should be free of lumps and of even color, if in doubt use more primer.Consistency should be a bit thinner than honey, if yours is too thin you can add more ABS/PVC or let the primer evaporate off while stirring it every now and then.To get a good start I do a few turns dry first with quite a big spacing.When approaching the actual start of the winding area I use some stick tape to make the last alignment and start to apply the mix onto the first bit of the winding area.Some lint free cloth with a bit of primer is used to wipe off any excess towards the still uncovered part of the pipe.Every time the mix on the pipe dries out too fast a brush with some primer is use to wet it.Every time the excess runs out a bit more mix is applied onto the wound area.The key is to only have a small area in front of the winding covered with mix with the most is on the winding and "cleaned" off towards the empty area.This way the entire wire is covered by PVC all around.To finnish off you simply use a brush and paint the mix onto the rotating coil until you have an even finnish.What are the downsides?The primer stinks and is certainly not healthy to breathe in. So good ventilation is a must have and it works better in colder temeratures as it gives you more time.It might require some test runs with braided fishing line or similar to get a feeling for how much mix or primer you need to apply and how much max tesion you can use to preven the wire from sinking in.Any benefits?IMHO using this method makes it possible to get a proper bond between the PVC pipe and the wire.And by using PVC or ABS as the coating there is little to no change material properties.This in return gives far less chances for vibrations or wire expansions that result in failing insulations.The whole thing just is one piece of PVC with the wire embedded in it instead of having a wire on top of the PVC with some coating above. ;)Are there alternatives to the PVC primer?If Acetone is much cheaper than you can use it but the same safety measures apply and the mix might dry a bit quicker.What if I need a break or stop the winding for one reason or another?Simply wipe off all access and stop with just enough tension on the wire so you can star again with no problems.Then start by wetting and applying the mix and continue winding as before.

Painting Wood

I've got some wood that I'd like to paint over, but it's currently got a fair bit of paint on it. The current paint is in fairly good shape and is just a little dirty. The problem is that the paint doesn't run all the way to the edges of the wood and cuts short about 3 cm from the edge of the wood. The paint is also peeling towards the edges. The reverse side of the wood has a few crevices running along it(kind of looks like a turtle shell) as well as a few peg holes. My plan is to sand the front all over and try and smooth the edges of the paint where the paint is peeling. For the other side, I'm going to fill in the crevices and holes with wood putty and then sand over as well. Afterwords, I'll probably apply some dual paint/primer spray paint on top to give it a smooth finish. Now, I have a few questions: 1. Will the peeling edges be a problem when I paint over the wood? 2. Since the crevices are fairly shallow and smooth out pretty easily, will wood putty be a good choice for filling them? 3. Any problems with using a dual paint/primer? Or would it be better to use a separate primer and then paint? I've never really painted anything, and this is pretty much the first real craft project I'm working on, so any advice would be great. If you think it might be a better idea to remove the paint, any ideas you have on how to do it would be great too. I've attached some pictures from various angles. You can probably guess what I'm going to be making :). Thanks.

Semi Autos (Face the Truth)

Semi auto guns are very cool. I agree but we have to face the facts. The way a real gun works is the pin hit the primer on the bullet igniting the powder and the extra gas is used to release the shell and load another bullet. How can we replicate this powerfully. Even today real bolt action guns are more powerful than semi autos. I am afraid to say that is just isn't practical to make that out of knex.

Lets pretend i wouldn't waste your time if i didn't triple quadruple check the wiring first. using 24v dc power supply schematic and page i based my driver on.   i am not getting the high pitched noise from the flyback. i have 5w 220 resistor and a 5w 27 resistor . my resistance ratio is important. correct? since there is a voltage divider there. i know its vague but can someone give me some direction to work out my problems
