Two 6 in vs. four 4 in hinges? Answered

I’m working on a project, part of which connects two door-type panels to each other using hinges. The weight of the panels—even together—likely don’t add up to 176 lb, but I’m using double-acting hinges, the models of which are available only as follows: a) 2 pk of 6 in. hinges (total weight up to 176 lb) b) 4 pk of 4 in. hinges (total weight up to 176 lb) What are the benefits and downsides to using more [smaller] vs. fewer [larger] hinges? What would you recommend, AND WHY? Please only reply if you have a reason/backing for your opinion; I’m looking for facts and legitimate reasoning, not merely personal preferences. Thanks!!

How can I add a hinge to a candy tin that doesn't have already one?

I've got a candy tin that comes as two separate pieces (top and bottom) and I'd like to add hinges to it kind of like how altoids tins have them. What would be the best way to go about it? I used altoids as an example but any hinge that's small enough to fit on the tin and joins the two pieces will get the job done. My tin's dimensions are: 4.6875" x 2". The bottom piece has a narrow part on the top that allows the top piece to fit onto it, those measurements are:4.5625" x 1.875". This narrow part reaches1/4th of an inch into the height of the bottom piece and has 4 bumps sticking out of it (2 on both of the long sides)  to keep the top in place similar to what's on altoids tins.

welding steel near aluminum, insert wisdom here!? Answered

I have 2 pieces of aluminum that make up a kind of finger hinge.  The two sections are each 3/4" wide pipe each ending in finger joints with a hole drilled through the fingers.  A cotter pin has been used as the hinge pin during the mock up, but now a permanent hinge pin is required and due to space regulations it must be very flush and end on either side with a flat round, similar to a nails head (striking surface).  I was going to merely insert a nail, then put a tightly fitting washer over the other end, and briefly mig weld the end of the nail protruding through the washer too the washer.  The opposite end will have a small thin piece of cardboard as a temporary spacer to ensure a snug but not too tight of fit.  Of course the rest of the aluminum will be shielded from weld spatter.  The weld would then be ground flush.  There will not be a lot of tension put on this weld, but some minor vibration. There will 5 of these pipe section with 3 joints per section each, they will be very close together and require the ability to move independently from each other, so no shared pins. Will a very brief weld cause the pin/nail to heat up to a point that it causes the surrounding aluminum to melt and "horribly" cause the 2 joints to fuse? The 3/4 span is much to wide for a pop rivet and would have to much of a bump on the sides. Bolt and nut would also have to much of a bump, and introduces the destructive effects of a steel thread running through an aluminum body. Philadelphia screws are just too wide for this application Actually peening a real rivet will put to much stress on the aluminum pieces. No I do not have the means to weld aluminum, as this is a solder core wire feed welder, not a true mig. Any suggestions?  I have done similar welds before, but all pieces were steel, not mixed.

What hinges do you recommend for a barrel cabinet door? Answered

I restored an old wine barrel and will use it as a kitchen island. I cut a door out of it, but am now stuck on what hinges to buy for it. does anyone have any suggestions on what hinges, and how to mount? The best I can think of right now is to mount inside hinges that flex out allowing clearance for the doors edge. But that seems bulky. Keep in mind that the barrel is rounded and so just straight mounting two simple cabinet hinges won't allow for the curvature and clearance.  Any tips is really appreciated!  Thanks!

How would I fix a cracked laptop lid?

Hello. I have a laptop that's several years old. During its service, the lid has cracked near the hinges. The hinges themselves are intact, but the bottom of the lid is almost completely cracked along the length. The question is: how would I fix it, without causing permanent damage, cheaply and make it last at least 2 years? I can work with wood, but not metal (no equipment for that). I'm on tight budget so I cannot afford to spend more than 10 GBP. I'm located in London. Does anyone have any suggestions?

What are some good primary weapons, side arms, and grenades that use few special pieces?

What are some good primary weapons, side arms, and grenades that use few special pieces? I know there are many guns that I want to build, but I have to stop in the middle and I realize I waste over an hour (or more) building a gun I can't finish or use. Almost always it is for the same reason...I don't have many special pieces. By special pieces I mean: Y-connectors, Hinges, Bendy Rods, Ball Sockets, etc. I only have 6 Y-connectors, and thats the most amount of special pieces I own. I really would like it if some people could post links to guns that I could build over spring break. When you post it, could you please tell me these things (if you can that is!): The name of the gun, whether it is a pistol, rifle, sniper, grenade, etc, If it has any special pieces (It can have 6 Y-connectors at the most I don't have any other specials), what you would rate it on a scale of 1-10, or anything else you want to include to help me decide which one to build. Again any help or guns would be greatly appreciated, and would help a beginner k'nex gunner get more building experience!

Now, the left hinge broke as well and the screen has the capability to completely twist around (see pic). The system turns on and the top screen still has power but it remains blank (see pic).

Book cover Hinge

Hey all. First time poster here (second attempt, since Instructables stopped responding the first time) so hopefully I am posting in the appropriate place. I have in mind a leather-book-style cover for my tablet that I'm very excited to work on. However, I would like to use friction or torque hinges to position the cover at any angle  from the spine in a 180 degree radius and have it stay there, similar to the screen of a laptop rotating around the hinge. I've included a picture that shows the basic design that I'm aiming for, though the hinge itself doesn't need to be ornate. Unfortunately, I don't really know where to find such a thing. I've looked on various furniture hardware sites and taken a trip to the local hardware/home improvement stores, but I haven't found anything that matches what I'm looking for. Common small brass butt hinges would be ideal if they had friction/torque properties to them, but I can't seem to find anything like that. I've never looked for specific hinges before though, so for all I know they've been right in front of my and I didn't realize what they were. Does anyone know where I can find such hinges, or can someone offer up an alternative solution? Perhaps there is a way to add friction to simple hinges bought from a hardware store. Thanks in advance for pointers/advice.

Two-way hinges

My wife and I bought an 80s designed house that's not that well designed. We keep one of the litter boxes for our cats in the garage, which is accessed from the inside through the laundry room; and we want to install cat doors so our aging felines can pass through the doors easily to get to it, while keeping the draft from the garage out of the family room. The interior door (between family and laundry rooms) is a standard hollow core and the exterior door (between laundry and garage) is fire code rated solid wood door.  We tried a standard top-hinged door with the cats already, at our old apartment, and the cats didn't take to it, so we we're hoping to do french doors, since they know how to get through normal doors pretty well. But we're kinda stuck on our lack of knowledge about hinge designs; we need hinges that swing both ways. Has anyone out there successfully completed such a design/installation and would be willing to share pics and secrets?

Speed Limiting hinge? Answered

Ok, I'm building a motorized projector screen, almost exactly like this: http://www.youtube.com/watch?v=GgIqx-iKNcw , except on a much larger scale. The actual screen will be made out of blackout cloth (what the back of curtains are made out of), and the screens construction will be similar to this: https://www.instructables.com/id/Cheap-DIY-100quot-Projector-Screen/ . The screen's size will be somewhere around 20x20 (feet), because it will be used in a fairly large auditorium. The screen will hinge up and reside (when not in use) above the stage. The top of the screen will have some hinges attached, so the screen can "fold up" into the ceiling. Toward the bottom, on the back of the screen, there will be a steel cable attached to the frame. This steel cable will be fed into an electric winch, which will be mounted on the ceiling. So, when the electric winch is activated, the screen will either hinge out, or it will hinge up into the ceiling. I know its hard to understand, I've done all the explaining I can. Ask questions if you have to. Anyway, the problem is this: What if this steel cable broke/got frayed and snapped/got chewed up by a darn rat, etc? The projector screen would come hurtling forward, knocking out anyone in its way. So, I need something that limits the speed that the screen can be lowered. I need some kind of hinge that limits how fast the screen can be lowered, so if the cable does snap among other things, the projector screen will make a graceful descent and people will have enough time to get the hell off the stage. Now, Do I think the steel cable is going to snap? Hell no. In fact, the steel cable I'm planning on using will handle over 1000 lbs. The total weight of the projector screen? Maybe 70 Pounds, at the most. These speed limiting hinges are just for that "extra" step of safety. So, does anyone have any suggestions?

Acrylic on acrylic hinge - friction?

I'm building an articulated 'puppet' using 3mm acrylic sheet for the 'skeleton' My hinges will be simple sandwiches of two outer and one inner piece, held together with a snap-together nylon rivet. The flat contact area is about half a square inch (see attached image). The 'puppet' will be controlled by tendons attached to gloves, so will only have the force of single fingers to move them. I need to know how smooth a joint this will be, before I start ordering nylon washers. Anyone got experience of this sort of join? Will it be ok dry, or will a small amount of  lubrication help? (petroleum jelly? liquid silcone?). Or do I need to commit to washers. Needs to be as frictionless as possible!
