  • That's a really good idea! I think I'll make mine a bit simpler, however. Purchase a fireplace video for $5.00 and a DVD player for $35.00 and I will have a 44" fireplace where my TV is. And in the summer I can have a waterfall on the TV.

  • There is only 1 type of plywood that is made well enough to not have voids, and be stiff enough to be successfully used in a CNC machine. That being Baltic Birch and those parts are not Baltic Birch. The metric equivalent to 1/2" Baltic Birch has 9 plies all birch. The metric equivalent to 3/4" has 11 plies all birch. It is sold in 1500mm x 1500mm sheets (5' x 5") That machine is likely good enough for wood projects, but not metal.

  • With that sort of neatness, I shudder to think what the rest of your living quarters look like.50 books, huh? I'm thinking you are quite young. That's good that you read.

    You could also save space by just throwing your clothes, towels, wash clothes, etc in a pile on the floor.

  • yrralguthrie commented on AdrienR's instructable Screw Sorting Machine

    Great work. Just reading and looking at the pictures, I'd say that cost $200-$300 USD. Plus 40 hours of build time. In the US maybe $20.00 an hour. So $1000 to build it. I hope not on company time! Might be more cost effective to just build the boxes and not make the mess in the first place though.

  • Actually a good instructable, some folks would be able to downsize it by about half and make use of your techniques. In the US at least likely 80% or more of the workshops are in garages. No way for a clamp rack or lumber storage such as yours could be a priority. Clamps are usually kept on the wall, and that much wood storage would just be a dream. Lots of professionals write great Instructables, that are just not useful for most of the readers of this reflector.

Most of the time when an author introduces themselves with "professional or with their considerable accomplishments", I simply pass them over, in the belief that their instructable is for their edification. Use professional techniques and experience, but on a level non-professionals and amateurs can benefit from without having to rethink and redo the instructable.

    Why not just order the holder(s) when you order the test tubes. They look very similar to what you 3D printed. Pretty cheap also.

    Don't take offense, but since you have a laser printer why not just try to print on one test tube. Lots easier than wading through what could be garbage on the internet. Especially since the test tubes are likely from China and there's no way to tell what kind of glass they are made of.

  • Without including your enthusiasm, for a project you have invested in, how effective are these? I ask because I didn't know memory foam was particularly effective in sound dampening and you don't cover a lot of wall. And I believe the foam would be more effective without a cover.

  • I don't know this, but I expect some of the computer parts that people think are aluminum are actually zinc especially if casting lines can be seen.

    What is jewelery?When collecting aluminum, be aware that quite a bit of the metal that looks like aluminum isn't. It's is either magnesium or zinc. For one instance and to point to objects that might not be aluminum, many electrical hand tools are made from zinc or magnesium, mostly zinc. If something is made with a die casting it is likely a zinc alloy. Zinc is easier and cheaper to cast. Dies last longer. Old car carburetors look like a source for aluminum, but they are generally zinc alloys.

  • The battery voltage must never go below 3.0 volts. Better is 3.5 vdc. This is critical. If 18650 lithium ion batteries are discharged to 0 volts they won't last and may die after 1 cycle. These batteries are generally charged to 4.1 vdc and discharged very rapidly to 3.9 and stay above 3.7 for a long time and then discharge very rapidly. For optimal performance, they MUST be not be discharged below 3.6 vdc. If they are discharged to the point where manufacturers say is the absolute minimum (3.0) the life is about 30-60 cycles. If charged at 3.6 volts the life is perhaps 600 cycles. There is little point is discharging past 3.6 anyway as there is very little power left by then. Trying to be nice, but truthful.

Great idea, bad implementation, that motor is not nearly powerful enough. Even if it were, the rpm's are way to slow for an effective dremel type grinder. You can say it'll cut through metal, but it'll take a long time to do it. Even a Dremel tool turned down to a few hundred rpm's will not grind or drill effectively. It'll polish delicate objects and that's all this build is good for. A motor that draws around 2 amps at 12 volts is only 24 watts. Most of those fan motors are going to be closer to 10 watts. I read the instructable because it IS a great idea. But it would be a waste of my time to use a muffin fan motor to build one. I believe this author is misleading readers. Again, great idea, but not with a small muffin fan motor. There are lots of small high rpm motors available for less than $5.00.

  • Not sure I see any purpose in this. Why not just lower the bit to the mark on the part to be drilled? No worry about alignment. The dot is going to be larger than a small drill to spot drill anyway. Remember if you want a precise hole you need to mark the spot, then use a punch to physically mark, then predrill and then drill. No purpose for the laser. The hole should already be marked with a punch before doing any drilling. Looks like a solution to a problem that wasn't a problem.

  • I see the posts about this not purifying water, and want to add an additional few words.I mean to yell.THIS WILL NOT MAKE UNSAFE WATER SAFE TO DRINK. All it does is remove some of the visible contaminates. Just makes the water look better. The unsafe bacteria and chemicals in water will still be there. DO NOT use this expecting to have safe water to drink.This person does not know what they are talking about. They have posted a very unsafe instructable.

This one also had a remote control feature so a very small child could be put in it and the parent could control the car. And no sharp metal corners to hurt the kid.

  • Why did I assume he was sorting used screws...I looked at the pictures.

    View Instructable »
  • An excellent write up. Very thorough. A lot of time spent on the written word. (A declining skill) Based on the results shown in the pictures I agree it's a slightly usable toy. And very few used screws are actually usable anyway. If they are marked I'll just pay the few cents it takes to buy a new screw. I value my time building too much to intentionally use ugly parts. I make enough mistakes as it is, without intentionally adding flaws. Screws are cheap. Many times I can buy them for $3-4 per pound. The biggest drawback to the project in my life would be the time spent building the machine vs. sorting by hand.

  • Nothing against this man's build. The instructable is well designed.Traditionally a sled of this sort is called a panel sled and used to cut large panels. Cuts that would be unhandy using the fence. It's not a miter fence. Table saws have a miter gauge, which is adjustable for angles. It's for making angles, hence miter.I think most will find the sled unhandy for cutoffs. Mostly since the fence can't be used with the sled on the saw. The sled also has no advantage over a zero clearance insert for clean cuts, and the insert is easier to make. It's also going to reduce the maximum depth of cut by the amount of the thickness of the sled. If the sled is more accurate than the fence or miter gauge then something is wrong with the fence or miter gauge. Fix them or buy better rather …

If the sled is more accurate than the fence or miter gauge then something is wrong with the fence or miter gauge. Fix them or buy better rather than adapting something not actually meant for cutoffs. For a small table saw there is really no need for a sled as there is a limit to the size of panels that can be cut. That said the sled he made will make good 90-degree cutoffs, but no better than the basic saw with a zero clearance insert. I believe this person made the video before he became completely familiar with using a table saw.

  • Good instructable, but a warning.In the US, few RV or mobile home parks are going to let a homemade RV park in their park. Most use the excuse that it may not be built according to standards. Yours is going to have additional problems. It's not going to fit in with the rest of the RV's. Odd shape along with pork and corrugated siding will get you excluded from a resort park for sure. Some parks in out of the way areas or very rural red neck areas will, however, take your money and let you in.

  • yrralguthrie commented on a mateen's instructable Razor Saw

    Good instructable and good construction for traditional US saw. But for small saws such as this the Japanese know best. A pull saw, a saw that cuts on the pull doesn't require the back blade. If you had reversed the blade when making the cut for the new blade it would cut on the pull. And it would then cut very thick material. And also cut flush. If you haven't used a pull saw you should try it. They just work better. How did you sharpen the saw. It had to be less than sharpe.

You made the statement that your setup purified the water just fine without carbon. How do you know? Clear water doesn't mean pure water. Activated carbon has a very important role in actually purifying water. Your setup even using the bleach does nothing to remove heavy metals, which is a major step in getting water ready to drink.You state emphatically that this method is the way drinking water is purified. That's false information, it is only part of the method. I'm sorry, but this article could be dangerous to anyone depending on using the techniques to actually purify water. Dirty water is not necessarily harmful.Sand filtration does nothing except remove large particles, to purify water some method must be used to eliminate biological pathogens and heavy metals. Regardless of the energy used dirty water that has been boiled is much safer to drink than water that has been cleaned by filtering.When using bleach the concentration of sodium hypochlorite is important. Do not use scented or color safe bleach. And a lot of bleach has additional cleaning agents added to it. Don't use that sort of bleach either.This statement is just made up nonsence.* Tip* If you can still smell bleach after forty minutes, wait a little bit longer, it is probably still killing bacteria. Once you can no longer smell the bleach, the water should be totally safe to drink.It would be quite easy to not smell the bleach and the reason being just not enough bleach was used.The whole article is full of made up thoughts and assumptions.In a water emergency all public agencies recommend boiling the water. Better to use some energy than get sick or dead.

  • When I see builds like these I wonder how things get priced in various parts of the world. This type of clamps is quite cheap in the US. Bought from Harbor Freight they are $2 to $5 each, which is less than what it would cost for the metal and welding supplies in the US. Then I think, wait, they are made in China! Why do they cost less here than in other countries in that same part of the world! Or do the metal and welding supplies cost much less in other countries. Never the less a good instructable.

  • Well that is the wisdom that is repeated often. I think it's urban myth. Ball bearings won't last as long as sleeve bearings, but ordinary sleeve bearings have significant drag. (excepting the sleeve bearings in engines) Ball bearings are used daily where side loads are the prevalent loads. Those ball bearings in the drill presses are not going to fail because they are ball bearings. They might fail due to being very cheaply made. Let's see, wheel bearings, including cars, table saws, circular saws, Dremel tools, lawnmowers, trailers, routers, all have ball bearings and significant side loads. And that includes some quite cheaply made tools.

  • PLA might be able to withstand 11,000 psi, but it would have to be solid to do so. The ridges on the embossing blocks you are making won't withstand anything like that. If I step on a lego in the dark it's likely I don't have shoes on and the reason the lego doesn't break is my foot gives first! Even with shoes I can't put but maybe 100 psi on it. Not unless I pick my foot up and stomp on it with rengence! Not nearly the same thing. I can certainly step on plastic project boxes that have been 3d printed and break them. Professional leather workers use a small metal tool or a single letter at a time. I don't think your embossing with the plastic plates and vice are going to last.

While it might not require much pressure to emboss wet leather it will take a lot of pressure to make it last. I have items that didn't last a long long time and I used a hammer and individual metal letters.VERY good idea, I actually like it, except for use of plastic. After you have had one of your projects actually last a long, long time you can call me wrong.

    What do you use for the printable media? Plastic is hard and durable enough????? I know everyone is enamored with 3-D printing, but this looks like a job a CNC router would perform better. One could use hard wood or metal for the blank.

  • Soldering and brazing are not the same thing. So you started off incorrectly. Too bad you capitalized correctly, because you got it wrong.Soldering requires less heat in that the solder is melted and flows into the joint. Brazing requires much more heat in that the material being joined is heated to its melting point and allowed to coalesce to help form the joint. And a rod is also melted to add to the joint.

  • Excellent instructions. For builders of wind chimes. At times I've lived for several months in an RV especially in the wintertime in the south. Wind Chimes used to be popular to hang on the RV awning. The problems was they almost universally annoy the neighbors, and not just a little bit. Apparently the particular frequencies are hard to shut out. So unless you live where others can't hear the chimes, you might not want to hang one up. I'm talking about knocking on doors, confronting the offenders and complaining to the park managers kind of annoyed. I agree with the neighbors, it's just additional noise they didn't ask for. Sort of like trespassing.

  • Good instructable.But I've always wondered what is the reason for eating gluten free. Gluten causes no health problems, unless a person is one of the very very few that are gluten intolerant. Ditto dairy products. Neither by themselves cause weight gain. Sometimes people on a gluten or dairy free diet do lose weight simply because they become more aware of what they are eating. Sounds to me like an excuse for people to shift the blame for being overweight to something they have no control over, rather than the fact they eat too much. Like saying "I'm fat, but it's not my fault". People have been eating bread for hundreds or thousands of years, but being fat is a 20th and 21st century problem.

  • I may have missed your source for the acrylic sheet. Even though you are in Scotland I'm curious since here in the US, 4 mm (.22 in.) acrylic sheet is going to cost about $6-$8 a square foot. Or $70-$80 a square meter. Which would make the cost of the acrylic about $500. And unless one is lucky it would have to be shipped which would likely add $100 to the cost. I checked and many home supply big box stores don't sell panels that size.
