It Took a While To Figure This Out

[@MossSteiger]

I really like the shift to problem-solving-type videos. Watching your thought process through the project highlights the “what” and “why”, and is more than just the “how”. Thanks, Bob!

[@Robc509]

Yep I came here to say the same thing! Very interesting the see the thought process and the evolution!

[@MichaelHarrison37]

Yep, totally agree. It's helpful when learning how to solve problems to watch other people solve problems.

[@se-ri2ij]

SAME I LOVE IT.

[@pipdesignshop]

I love watching the problem-solving process. Instead of watching you come up with a solution that may not apply to me, my brain is engaged, thinking of possibilities and ways I can solve similar problems.

[@stoneobscurity]

metal strips along the joists and then a strong magnet on the camera pole.

[@DS321o]

that wouldn't work at my house once my mother-in-law visits because the joist would violently shake and potentially drop the camera

[@ryandury]

Not a bad alternative

[@BrianWood74]

​​@@DS321oI have a magnet that are about the size of a nickel that I have on my 20v Milwaukee drill that I use to stick it to my bench, it won't come off without force. It will absolutely hold a pole and a camera like that with zero issues.

[@simonolphin]

That's a good suggestion but it's very wasteful when it comes to material. Bobs solution, as usual, not very time efficient 🤣 but, saved loads of waste.

[@CL-gq3no]

@@simonolphin, A couple dozen 1" x 1" steel plates screwed into the ceiling and a 3D printed adapter/base with an embedded magnet sounds pretty efficient and effective to me.

[@SimpleTitle]

Been watching you for years now and as much as i really love your project videos, I REALLY like these "got a problem, chill with me while i figure a solution" style you've been doing more. I hope you keep sprinkling these in as you encounter them, its really great to see someone else's problem solving mind at work. Thank you Bob

[@cooperised]

Lol @ 1:10, "I'm not gonna do that." Good for you! I love solving little problems by creative thinking, not by spending money, even if the problem's already been solved. The joy is in the journey. I guess your channel name sums it up!

[@TomAllenBird]

Exactly! This is “I like to make stuff” Not “I like to buy stuff”

[@wirelesmike73]

I'm 2:30 in, and I already like this. I love problem-solving videos like this. Even if the problem is not necessarily that big of a problem. I just like seeing the creativity and ingenuity involved in reaching a solution.

[@CParsley]

Picture the broom handle holders that feature a captive rolling piece on a ramp. The broom handle is inserted from the bottom, pushing the rolling stop up. when the space is big enough, the broom handle slides past the roller. Then as you let go of the broom handle, the combination of the rolling piece and the ramp, wedges the handle in place. If your "clamp" was two of these facing each other and the largest space between the rollers was just wider than the thickness of the joist closest to the clamp and narrowed as you moved towards the end, you could twist the entire contraption just enough to get the rollers to catch on either side and wedge it in place. Releasing would just be lifting it up and letting gravity pull the rollers down, releasing the clamp. No need for any hardware other than the 1/4x20 needed to mount your camera adapter.

[@ToddRafferty]

This was my first immediate thought too. Glad I'm not alone

[@swissfreek]

@@ToddRafferty me too! There was a compliant mechanism video from… someone (I forget who)… where they talked about how to design that part and 3D print it out of TPU.

[@MathewPuthiakunnel]

Exactly the same thing I was thinking, came to the comments just to see if anyone else thought of it

[@TwiggyC]

Agree with a lot of what others have said about the recent videos regarding problem-solving skills and just making super specific use-case items. As a recent 3D printer owner, I'm constantly looking at my shop and home differently with an eye of how to solve specific problems. Way to differentiate the channel and really stand out, Bob and team!

[@angusg.2049]

Thank you so much for using your videos to show off prototyping and failure. Too many people don't make the stuff they want because theyre too afraid that it won't be perfect on the first try. Your content shows that it doesnt have to be. And it shows that theres value in making mistakes and drafting things.

[@buffaloxp]

You seem to be in a season of efficiency. Finding things that annoy you just a little bit, or could be just a little better and finding solutions for it. It's so cool to see these little projects that can help so many people in so many ways. It's a big change from major projects that garage woodworkers will spend weeks on, and I love it.

[@bjsmithart]

I’ve really been enjoying these types of videos you’ve been making lately. It gets my brain working to try to find creative solutions to issues. My art studio is basically a 60 square foot clean room off of my workshop. Filming in there is a chore.

[@meikgeik]

You forgot about another force... Squeeze. You could have a handle with a cable connected to it like a brake lever to transfer the force to the clamp. ❤

[@Nevir202]

Only issue there, is that he wants to use the telescoping nature of the camera pole. If you size the cable to be long enough for full extension, when shortened the cable may then hang down into shot. Obviously that can then be managed as well with an elastic that always pulls cable slack up, but it does mean making the think jamnkier, more complicated an ugglier.

[@kevinetheridgemakes]

Bob, you've really been singing my song these last two videos. I love this idea. I think there are so many folks that are inspired to make little videos - maybe they upload them, maybe they don't - but the bare joists / studs in many of our garages really really lend themselves to something like this. Kudos.

[@jonwills1957]

I enjoyed seeing your practical attempts before moving into fusion to figure out the problems!

[@WildernessWarriors1]

Love this style of video as well. Different design with less moving parts: 2 prongs to straddle the joist rigid in place. rotating cam on each prong with light spring to pull to the inside. pull string attached to the other end of cam to one string to end of handle. pushes onto the joist easily, the more weight pulls down the tighter it gets. push up slightly and pull string it releases both cams and slides easily off joist. less printing, less moving parts. the larger the cams and wider the forked prongs the larger the object or joist it will hold onto. make it out of metal and it will hold hundreds of pounds.

[@chifii]

Of note when you're using that 3d camera for future shots; because the image is stitched together from multiple cameras, plus the housing and whatever, the software in the camera does some trickery to blend the shots together - particularly when you pan the shot up so you don't see the pole, or directly opposite from that looking "down" (in the orientation you're using it, anyway). You can see the distortion particularly well with the cut mat you have under there. So it might be useful to have the camera rotated if you want to capture a horizontal surface below the camera. Or reuse that solution with a slightly different camera mount to get top-down shots of small parts if that's what you want. Really cool build!

[@lucusloc]

You can do the same thing with zero moving parts by exploiting some leverage. I have some "self gripping hangers" I got from Amazon that demonstrate this principle wonderfully. They can be moved around with ease, but as soon as you put weight on them they lock in place and will not let go. The more weight you put on them the tighter they grip. You can search for the product above, but I will try and put a link in a reply comment to this one (it will probably get flagged as spam). I think if you built a hook with the camera pole offset from the hook by a few inches that would give you more than enough leverage to firmly grip the device to a rafter, and there would be zero moving parts to wear or get sloppy. Take a look and see if it works.

[@Zengineer]

Take a look at how log skidding tongs work, the weight of the "pull" locks them in. A similar mechanism would work very well here.

[@scottcates]

He is reinventing the wheel. Your log skidding tong example is also represented in ironwork to lift steel. They're called Plate Lifting Clamps -- essentially a gripper that translates pulling effort into clamping force. Tongs are great, too.

[@samueldeter9735]

​@scottcates would minimum weight be a concern for such a light camera? Or accidentally bumping it or something?

[@TheNewJankyWorkshop]

Even if the "thing" you is making isn't a problem we all have, seeing the ideation, prototyping, and troubleshooting is extremely interesting to me. Thanks for bringing us along Bob! Although, when I eventually break down and get one of these cameras, I may have the exact same issue.

[@TheSmugglersRoom]

I am absolutely loving these episodes with the awesome thought process and problem solving man. So fantastic

[@raphprobably]

I've been loving all these "let me take you along my thought process" videos you've been doing lately. It makes me feel better about all my failed attempts before getting something working knowing professionals still go through the same struggle. Side question, what do you do with all your scrapped 3d printed parts?

[@neilf4128]

Hi Bob. Love watching how you've grown all these years since you started making content full time. Thank you for your passionate dedication.

[@beaushaw]

Two feather boards that go around the joist. Shove it up, pull it down. No moving parts and it could be printed in one go.

[@jack002tuber]

When I need a strong spring and don't want to buy anything I go for bike inner tubes. Real strong and cheap

[@rashkavar]

Very nice - one other potential application for this kind of thing: put a light on it, and you can have a light you can position to fix any shadows you're finding get in the way of your work. Obviously, you've got a pretty decent lighting setup already, but for some shops this would be great, and even for yours you might at some point find yourself with a super niche setup where you have to be working in such a way that you throw a shadow over your workspace. For less established workshops this would also be a really good way to figure out where you need extra lights - use it as you get started, and then invest in permanent light fixtures over time.

[@chasingsomething3735]

Dude your last fire videos have been top tier. You inspire me to make more thangs and finally buckle down on starting my own videos

[@ChromeDisciplesCC]

I had somewhat of the same situation but I needed to move a spotlight around. I just stapled strips of velcro to the ceiling and more velcro on a bracket for the light. It’s been working for about 4 years without an issue. I do like how your clamp looks way better than strips of velcro on my ceiling.

[@shannim5]

Great video, Bob! As a career (non-mechanical) engineer, I love watching your videos and thought process each weekend to solve practical problems. It's one of the highlights of my week, every week. I appreciate your engineering mindset of breaking down the objectives, prototyping, trial and error, etc. I do this as well all the time. I also totally love the over-engineering you often do, because often times you think of things and methods that I never would. In this case, I'd probably just mount some small metal plates all over the ceiling and a strong magnet to the quick release plate or selfie stick. But what's the fun in that? LOL.

[@Miniac]

2:35 in order to get this stop motion, did you draw the same images twice? Once for the wide clip sped up, and once for the stop motion?

[@BvrlyHillbilly14]

Idea for the system: make a system on your joists similar to how an etch a sketch works (x and y axis). Then attach that with a couple motors and a computer. Then program areas where you routinely mount your camera. Then have buttons that you can press to have the mount move to those predestinated locations. You could also have a manual mode that allows you to move it to locations as required.

[@RoxaneJ14]

Love seeing the process! Go ahead and search lifting clamps, they use gravity instead of tension and I think it could also be a great fit if you wanna do something similar in the future

[@MrLightPanda]

Really cool how you have a problem and then a solution all in one video! I'd say you're getting the hang of the 3d printing!

[@fcschoenthal]

You sure that you don't create problems just so you can solve them? 😁 Love to watch your thought processes anyway. - Chris

[@Iliketomakestuff]

I mean, probably, yeah. But I love to solve problems 🤷🏻 That's like a musician only listening to music, instead of also playing it themselves.

[@DoraThaExploder]

I highly recommend looking into 3d printed springs. It will be easy to test with your printer and can be scaled for many of the applications you've been using. Keep up the great work! I always look forward to seeing your projects!

[@KevinHorecka]

The two solutions that immediately came to mind for me were a large magnet and a push latch mechanism like what you might use for a self locking cabinet. I think your prototype 1 is basically that latter solution. Cool to see it made from scratch! Great if you need a custom size.

[@Rufio1975]

I have my own measley channel and your channel inspires man. Becoming one of my top favorites.

[@Kellerwerkstatt]

Hey Bob, long time watcher here. I hope a little critism is in order. I really enjoy your videos. There is almost something to learn or at least enjoy in your videos. This one i s no exception..... BUT thumbnail and title gave me no indication on what this video is actually about. So much so that I only clicked on the video as it was suggested for the fifth time and onyl because I had nothing better to do at that very moment. I know that your trying out different title and thumbnails over time. To see which one performs the best. I get that. That is why I am writing a comment. For the first time if I am not mistaken. Had I seen that the video was about clamping stuff, clamp geometry or something along those lines I would have reacted sooner to the video. But as I said I had no idea what the video was about. Anyways... thanks for your content and best Regards from Germany, Daniel

[@mikebond6328]

What are you criticizing?

[@Kellerwerkstatt]

@@mikebond6328 that neither thumbnail nor title gave me any idea what the video is about. ;-)

[@Iliketomakestuff]

thanks 👍

[@BillCarlson]

Watching the video I just couldn't help but see the similarity between what you made and a bicycle brake. In fact, my first thought for solving your problem would be to use the full brake system with a ratchet and release mechanism on the handle. Squeeze it together and it ratches and holds on to the joist, then squeeze a bit and release a latch or something and it comes off.

[@danthemakerman]

Nice solution to your problem. Really cool to see you using the 3D printer for rapid prototyping.

[@Podwojniak]

I love these kind of videos. Your thought process should be teached at schools so everyone can solve their poblems themselves.

[@DS321o]

Sick! I love the solution you came up with. Moving it from joist to joist almost looked effortless!

[@CL-gq3no]

Consider printing a TPU band for the "spring". Then you don't have to source the perfect spring. The bands tension could be set by varying the infill percentage and/or by selecting narrower/wider groves along the clamp to anchor the band in. It could pretty much be a rectangular rubber band that stretches over the clamp arms and seats into groves on the outside of each clamp arm.

[@p07gbar]

My impression is you might have less issues with the foot geometry of the bulk of the foot was on the inside side of the pivot rather than the outside side, this way it would self correct into place more readily

[@davidcenteau-depina6192]

I would have loved this about 10 years ago: videoing a band in a run-down house with multiple cameras mounted from the joists. It involved a lot of being on a ladder and moving cameras around.

[@gaviningram2850]

I like the idea of using a grabby hand toy as a possible solution, having it stay closed with a strong spring and a pull on the handle to release it. No idea if it would work but a fun possibility for those who don’t have a 3D printer available!

[@gianmp7109]

I LOVE THESE PROBLEM SOLVING VIDEOS, but for this one I’m a bit scared it’ll fall, u should add some rubber pads to the grippers so u don’t break ur rly expensive camera, or even sandpaper tbh

[@masterofnone]

Another great problem solving video. I love this. Thanks for sharing Bob

[@ToolTimeToday]

Loved the video for sure. Inventing something like this to solve an issue for yourself is what it's all about. I to love problem solving, Gives the brain a little workout.

[@gehtdinichtsan309]

nice solution; first thing that came to my mind at the beginning was (very unrealistically): build some kind of monorail network on your ceiling, so you can "hang" the camera-mount on it easily (like a ropeway) and also move it around the shop.

[@toperishtwice]

I don't like 360 cameras because there's a distortion at the edges of the frame and it gives me serious vertigo

[@PGNogueira]

There's a 'dewarp' option that flattens the horizon.

[@nathanhiggins860]

Always love the problem solving, but me I'd just 3d print 6-8 mounts and spread them through out the shop. make it similar to power outlets, then you can move the camera easily from one spot to another.

[@qasimrx9869]

What if you stuck multiple steel plates on the ceiling every few feet, and just got a magswitch type of connection on the pole. Repositioning might make it smoother

[@mskadwa]

Because that would be too simple

[@michaelaguirre6252]

It reminds me of clamps you place on the wall that grab onto your broom/mop. Same tension operation. Nice work

[@blairleipst4508]

Perhaps a larger version of a jewellers vice would work

[@MarshallLoveday]

Thinking of another 'you-specific' solution: A two-piece bracket. The 'male' piece attaches to the camera mount. It would be 'L' shaped, with the vertical leg having a 'V' shaped slot that would engage with the corresponding 'V' slot on the 'female' piece. You could print a bunch of the female pieces and just screw them into various places around the shop. To disengage, you simply lift up the camera mount a couple of inches to separate the two pieces. (We're talking about a modified 'French Cleat' here, where gravity keeps the pieces together......)

[@howevisual7099]

I personally prefer (especially for DIY solutions) quick release plates for camera gear that has “location pins/holes” so that that if there ever were gear that could accidentally be rotated loose, the pins prevent that so you have to use a screw driver. Ulanzi Falcam F22 & F38 plates are my jam!

[@TheCapt]

I also like the problem solving videos lately. Sometimes I do think you go a bit overboard just to make the video though. For this one, I think a simple V in a board that the grove starts a little bigger than the 2by and gets narrowly below the width over several inches. Then you can just ram it up. No moving parts. Probably make it out of a chunk of 2x4.

[@Ceira]

One problem with the 360 cam: fish-eye.

[@Bill-YellowDogWelding]

and sea sickness

[@edwinburggraaf8224]

Nice! I would suggest to give it a bit of a twist when you pull the clamp off the beam so only the side will wear and not the surface that needs to grab.

[@RoachRider]

Shows how then you have a hammer, every problem looks like a nail. You have a woodworking shop and a 3D printer, so this path seemed obvious to you. I have neither, but I do have some parts I took off my bike so I would probably stay with the off the shelf clamp you considered at the beginning and add a cable and a brake lever to acuate the clamp remotely.

[@Gobhoblin126]

SURFACE AREA DOES NOT AFFECT THE FRICTION FORCE. The only variables are the coefficient of friction and the force.

[@famitory]

if you want a version that's hardier for a future application needing WAY more grip power, the kind of bistable mechanism used for pens and sd card slots might work. a trigger in the mouth of the claw gets pushed by the joist and makes the claws squeeze way harder, then pushing it further than that makes the bistable mechanism release the pressure again

[@garynagle3093]

Loved hearing you talk through the problems and possible solutions

[@Qoonutz]

I love your "problem-solving" videos. Keep it up! Well done!

[@decomputerleraarable]

I see also some possebilities with a few pieces of iron and some strong magnets

[@robsadler5605]

I was thinking more of a flexible TPU featherboard clamp which releases when you push it up onto the joist further. Much more complicated, especially when factoring in the release mechanism and printing of the featherboard.

[@ole1d]

Now that you've got that 360 camera, can you make a virtual tour around the entire workshop?

[@leggo0]

Really enjoying theese videos where you are making things you will be activly using!

[@nzlemming]

Interesting. My path would have been to model the camera clip that you put on the bottom of your clamp, and then print lots of them and install them on the ceiling all over your shop in places that are obvious and some in-between. Then you just have to detach the camera pole from one and put it in the next. Also, it would hold all your cameras through the same standardised base. Still fun to see your development process.

[@chadevjen7091]

I really like this idea! I was thinking some gears on the pivot side of the clamp arms to keep both arms in sync. Wicked cool!

[@JimWatters]

For the monopole to disappear from a 360 camera the camera does not need to be pointed straight down. The camera can be at any angle. The monopole just needs to come straight out of the camera. Using a ball head and changing the length of the monopole can place the camera in many places without having to move it to another joist.

[@Pommie]

An alternative approach might be to use magnets. It would mean that you would have to denote fixed attachment places; losing the ability to put the attachment absolutely anywhere, but I’m willing to bet that you tend to mount the camera in one or two key locations all the time. Might be interesting to see that solution as an alternate implementation to this project?

[@naasking]

The simplest solution is actually just mounting cheap steel sheet/plates everywhere and using a strong magnet on the end of your camera rod. Cool idea though!

[@mikebond6328]

You think it would be simpler and cheaper to cover the entire shop ceiling in steel plate?

[@naasking]

@@mikebond6328 Why would you do the entire shop? That's silly. Yes his solution is more flexible because it can go anywhere, but realistically you wouldn't need more than maybe 10 places.

[@shicaaaaa]

I also bought insta360 for my shop, but the low light video quality was just terrible, had to sell it. Does it produce any usable footage for you? I love these specific problem solving videos!

[@jacobeader8818]

Bob, i listen to your podcast with Jimmy and David, i know its a theopy session for you and from my perspective you're wrestling with finding purpose on KZbin and the stuff you make. With that being said i know your branding is "problom solver" and theres a reason for that, you are amazing at it. Let me tell you the second video of your camera stand was awesome to watch, even though i don't even own a film camera, becasue you are in the pursuit of perfection of funtion. All that to give you a recommendation to tear into old projects and make them that 10% better. That would be so inperational to makers that just cant figure out why thier projects are not quite right. No they dont have to be making the same exact thing as you but a funtion can have purpose on multiple things. You have a great problem solving brain and the last bit that turns something good to great , i think, is your niche

[@SarahKchannel]

You could also put a compression spring between the the finger below the fulcrum. This way you have no exposed springs on the side that get in the way. Maybe try to add some sand paper to the finger tips for more grip and less slide - TPU is not very good in providing friction.

[@mkegadgets4380]

I really liked this video. I would say this is one of your better ones you made,. What is the make and model of your camera? I’m looking for one for myself. You could remove all the nuts from the part and save weight by having the parts threaded. And use flathead cap screws might save a little weight too.Kind of give it a cleaner look too. Look forward to your next video.

[@Iliketomakestuff]

Thanks! It's the X4 from Insta360.. happens to be on sale right now (affiliate link) amzn.to/4hVYT0B

[@deltaangelfire]

Late to the party but what about using rotational force instead of springs to increase friction? If you have the weight of just a straight "clamp" some distance from the center, it should grip the joist and then to get it down, you just raise the weighted end to release the friction. bonus, no moving parts

[@HotelPapa100]

I haven't seen your solution yet, but my solution would be a knuckle clamp. Push to engage, pull to release. Depending on the variability of your joists it would need to be wdth adjustable. ETA: I don't trust the durabiliy of your lever around the holes in PLA, which I assume you are using. I predict you'll be beefing up that area after the first incident. ;-)

[@leannapancoast3393]

Love your solution! Much more exciting and modular and educational than my thought of stainless steel and magnets.

[@mikebond6328]

Stainless steel is not very magnetic.

[@mattsully5332]

Really enjoying the video, but I think you missed a great opportunity for a joke at about 9:00. Right after the printer made some spaghetti, then you plopped down the ready parts, you could have plopped down the spaghetti, and pantomimed trying to use it. I don't know that it would have improved the video, but I would have enjoyed the laugh, in a portion of the video where it wouldn't have been downplaying the message of the rest of the video. Also, I don't think I've said it, but I LOVE the life messages you've been working into some of your videos, and I plan to use them with my son's Scout Troop.

[@tomtruesdale6901]

Very well done Bob, I was wondering if a piece of spring steel like a tool holder could be used to clamp onto the ceiling ? I do enjoy your "problem solving" videos.

[@Duraltia]

I was kinda expecting for the solution to be more akin to how tree pruning scissors work with the Blades situated on one end of the Pole and the Grip on the other... In this case though you'd use the Grip to open the normally closed Clamps instead of the other way around.

[@aka_king1001]

Everyone is talking about magnets yes they work but they are the most common solution don’t forget the core idea of the channel is making stuff and being creative with different solutions to problems.

[@angryspacerasta1398]

If you mount the feet upside down, downward pressure will act to tighten their grip on the joists. No spring required.

[@alankeith7866]

As long as moving the camera isn't in the picture, mount magnets to the joists and a steel plate to the camera mount.

[@luvnotvideos]

If you have specific locations where you always set the camera, screw cup magnets to each location. Then all you need to do it lift the camera in place, or pull to let it loose.

did you consider having a grab handle at the bottom. think trash pick up tool. Reverse it to open when you squeeze, and close when you let go.

I think all the final bit needed is some sort of stop so you don't smash the spring each time. Perhaps just a 3d printed piece that you glue in a magnet that sits on top of the bolt.
