Turning a threaded rod with a motor?

Hi everyone, I'm wondering how I could make a motor (with a 4mm shaft diameter) turn a 1/4 in. metal rod. I'm planning on supporting one end of the rod in a piece of wood, and the other of the end will be attached to the motor so that when the motor spins, the rod also spins in the wood.

Gasoline-powered, but no wheels...

I heard about them, but I thought they were a joke.Then I ran across a link.They actually made gasoline-powered pogo-sticks that even grandpa can ride!It's a single-cylinder engine, with the bouncing foot being connected directly to the piston, called the Hop Rod. There are a bunch of adverts and slightly more modern test-drives in a short video on the site.They're... odd.Still, I wondered. Maybe the Hop Rod provided the inspiration for other wheel-less powered transports?Do you remember those Russian boots? 4 metre strides and speeds of 40kph were promised, but that was 8 years ago. According to The New York Times they fell foul of Soviet secrecy and then Russian financial mis-management.They're still around, waiting for some entrepreneur to hop on the band-wagon...

Use a motor to rotate a nut on a fixed threaded rod? Answered

One thought was to use a threaded rod+nut to propel the cart, and I want to look in to this method because it seems fairly versatile. So I would have a taught, fixed threaded rod running through the middle of my 8"x6'x1" track. The cart sits on top of that. I have the motor and the cart pictured below. How can I get this motor to spin a group of nuts (attached to the cart) so that it propels the cart along the threaded rod?

Reduce steel tube diameter by 0.3mm Answered

I am trying to make a DIY CNC machine, using linear rails and the expert advice in the many awesome instructables out there on this topic.  I hit my first roadblock, and I need some help/advice please... The 16mm steel tubes I ordered for the sliding rails wouldn't fit in the 16mm linear slide bearings SCS16LUU that I ordered, they are ever so slightly too big. With a lot of force I could get the rail in the bearing, but it wouldn't slide without extreme force - certainly not the smooth sliding motion it's supposed to be! I've probably ruined the bearings by forcing it in, but I'm not worried about that so much right now (I have spare bearings). I broke out the digital callipers, and the rail diameter measured 16.3mm - that's .3mm more than expected, and more than can fit in the 16.0mm bearings. So now I need to reduce the steel rails by 0.3mm. I have only hand tools at my disposal, and no experience accurately reducing steel rod diameter. I guess another alternative is increasing the slide bearing diameter, but these are sealed bearing units and difficult to get at. Does anyone have any ideas ?  Would it be easier to order new steel? Please let me know any thoughts on this, I'm desperate here.  Thanks in advance,

the use of threaded rods for cnc miller and cnc 3d printers

I got some threaded rods today. They look straight. 16 threads per inch.  The tag on one of the shorter ones says 3/8" - 16x36", course threads, zinc plated 1700lb. I was planning to use these for the x,y,z control for a 3d miller/printer. I realize it may be slow. Someone mentioned that the McWire repstrap uses a 4 1/20 (the only part I understand is 20 threads per inch) was really slow, but someone made it work with 2 1/16. I did not really have plans to attempt position verification because I think the resistance vs torque should be minimal for a threaded rod setup. I figure I could get away with just sending it specific pulses for a specific amount of time. Could I have some feedback on this?

How to tighten a nut on a threaded rod from the side, through a hole in a hollow tube?

Picture a threaded rod, with a hex nut on it. The rod is inside a hollow tube. You move the nut down the rod by inserting an outside hex wrench into the hollow tube from the top. But what if you only have access to the rod from the side, through a hole in the tube (which is fixed and can't rotate around the rod)? Is there a way to tighten a nut down a threaded rod from the side through a hole in a tube? Context: the application would be a grip for a fencing weapon. The base of the blade of a fencing weapon turns into a threaded rod (the tang). The bell guard (metal disc to protect your hand) has a hole in the middle, and is inserted onto the tang. The standard grip is a straight tube-ish thing (usually solid except for a hole the diameter of the tang). You stick the tang through the central hole in the grip. Then you stick a nut on the end of the tang (which just extends beyond the end of the grip) and tighten the whole assembly down. Some special grips are curved, which means that you have to bend the tang in a curve to match the grip first in order to fit it onto the tang. Another kind of grip is straight and hollow, with a plate with a central hole over the end butting against the bell guard, to give the nut a surface to press against, and the tang is cut much shorter than the grip, and you tighten the grip with an outside hex wrench from the back end of it, as I described initially. The advantage is that a shorter tang weighs a lot less, and the weight savings can be really good in fencing. I want to combine the advantages of these two types of grips- a curved grip, which is hollow and lightweight, with a tang that is shorter than the grip itself. Obviously, it would be impossible to tighten the hex nut through a curved grip, hence my question.

How to order the correct ball bearings and threaded rod so that they will seat well and not be loose or have play?

I am trying to design, what will essentially be a very specific miter box / saw guide for a hand saw. Here is a product on the market that is almost exactly what I am trying to build. The only difference between what I need to build and this miter box, is that the miter box from that link cuts at a 90-degree angle to the workpiece being sawn, whereas I need to saw boards at angles much more acute than 90-degrees. There are commercially available adjustable miter-boxes, such as this one, that allow you to set whatever angle you need, and it will still guide the saw straight. However, they are made for cutting baseboards and molding, so the angle-range is only 90-degrees to ~40-degrees or so. I am cutting wooden boards for making, "scarf joints". So, I need to saw through 4" thick boards at an 11-17 degree angle. Where the above miter box saws perpendicular to the board it is sawing, the one that I am building, at 11-17 degrees, will be closer to cutting parallel. The housing, I think I can cobble together from angle aluminum and hardwood. However, I haven't bought ball bearings since I was a kid riding skateboards. I was hoping to take a threaded rod and push it through the hole in some bearings, then use some spacers and/or washers to space them apart, and secure the whole bearings/spacer/bearings sandwich with some washers and nuts. I do not live near a place that actually sells bearings much less carries bearing and threaded rod in the same store. Therefore, I cannot try it all out right there in the store. So I am going to have to order the bearings and the threaded rod off the internet. I need bearing where... Heavy load is not an issueHow fast they spin is also a non-issue.But that are...Shielded from the sawdust (do not have to watertight)Fit snuggly on a threaded rod and not rattle around. A loose guide-bearing isn't much of a guide, eh?Would one of you fine gentlemen help me by pointing to where I can buy 16-20 bearings, a threaded rod that will definitely fit them, and some .50 - .75" spacers (metal or nylon) that will also fit the bearings?

I need some soldering advice from you guys

Hello Everyone - I am trying to solder a different type of a joint, and I'm having a problem doing it. I am hoping someone here can tell me what I'm doing wrong (or not doing). Here is my problem:I am trying to solder an alligator clip to a 3/16" dia steel rod (I have a picture of this joint, but for some reason, I can't upload it).When I heat up the joint with my propane torch, the alligator clip goes red hot first, and the rod takes a while longer. The rod turns a really dull red, but never as hot as the alligator clip, because the clip is only ~ 0.020" thick. I have a roll of silver bearing resin core solder that I am using. When I apply the solder, it just sorta balls up and won't flow over the metal at all. I end up with a bunch of melted balls of solder on my table, and that's it. I didn't try using any flux, because this solder is resin core. Is there an inexpensive way of doing this ? Does anyone here know a method that works ? thanks in advance, Terry

Why don't they use gigantic leyden jars to collect electricity from lightning and use it to power homes?

Seriously, I had this idea the other night when it was really stormy and lighting out like crazy. Why can't they make large collection centers for lightning, kinda like a leyden jar in principle, with a humongous lightning rod to attract lightning? Lightning is absolutely free, if it was harnessed to power our cities, at least some of them, it would be so awesome! No pollution, no cost to produce, other than construction and maintainance of the facility. You could just plug it into the existing power lines, with some massive step-down transformers of course. So why don't they do this, at least experimentally? Lightning is unpredictable, you say. No problemo, you put this collection thingie in an area where there are a lot of storms, and add a lightning rod-a BIG lightning rod. It's very dangerous, you say. So make it completely automated, no humans required, and put it away from residential and business areas. You say lightning is much too powerful. Nonsense, you can make a big enough facility to contain it. You say I've gone off my rocker...you may have a point there... I know it must be dumb, and have a flaw I am not seeing-do any of you science experts know what it is? Why won't this idea work?

Magnetic stirrer and springs....

Wanted to try how far the magnetic field of my new stirrer is reaching and observes something weird...If you have a normal stirring rod in a beaker then these things do excatly what they are supposed to.Even if you try to add the rodd to an empty beaker while the stirrer is already running.The first option gives you a nice rotation, the later often just some jumping and bouncing rod.Fun fact though: Inside a stirrer rotates a magnet and the rod is just a steel bar enclosed in polyethylen or teflon.Trying to make a stirring rod roll around the center instead of rotating is next to impossible - it always tries to use the max binding force and centers itself.So I tried different things for the end goal of designing a stand up stirring twoer instead.You know, like these fancy ones found in huge water towers to agitate the water.I found a small steel ball with two magnets attached quite interesting but an accident made me wonder...For some reason I did not turn the stirrer fully off when searching my little box of goodies for new stuff to try.A small spring for some motor bushes landed on the stirrer...And although it moved dead center it did not spin at all.A slight vibration was all I could see.First weird behaviur happen when I tried to move the spring around to check why it is not spinning.Pushing it a bit lengthwise suddenly made it spin!A bit of fiddling a trying showed it works best slightly off center to the magnet with one end while sitting on the radius.The spring rotated like a horizontal drill but in no relation to the stirring speed.Second and even weirder things happened when the spring slipped through my fingers.It started to roll around the center of the plate but in the opposite direction to the magnets rotattion!An increase in speed made it roll faster until the g forces made it fly off the plate.If you have a magnetic stirrer then try it out one day.I have a few theories why the spring starts to rotate or roll but none make fully sense.Can try to take a video for those with no stirrer but for the fun of it it might be good to just mount a magnet on a motor and try LOL

Need help selecting a small motor for moving a small rig back and forth left-to-right only about 1 inch.

I have never worked with motors before, and I am starting to realize that there are dozens if not hundreds of different types of motors. Imagine two 6" long, 1/2" dia. aluminum rods suspended between two pieces or trapezoidal shaped plywood that are secured to a base and braced to make this whole structure rigid. on these two aluminum rods "rides" a small carriage that is literally just a small 2" x 2" platform made from... whatever... 1/4" plywood. This carriage can slide left and right on these two aluminum rods. I need a motor that can somehow move this little platform left and right, back and forth, only between 1/8" to 1". I need to be able to control the speed (rate) at which is travels this small distance.I also need to be able to control the starting point and the end (return) point. Basically, I and transferring string from one spool to another. So the platform will have a spool of thread on it, and it will be going left-to-right while another spool is turning. The left-to-right movement will be coordinated with the speed that the second spool is wrapping (turning) so that the thread windes as close to "perfectly" in layers. And each spool will be between 1/8 - 1/4 - up to 1" wide. This is why I need to be able to set the starting point, and the end point where it will stop and reverse direction. I will be controlling this with a project board like an Arduino. I just need to know what kind of motor to look for, and any other suggestionsThanks guys!
