For shooting smooth panning shots, we use a device called a gimbal. It uses force feedback to keep our camera level and stable while it's being moved around. But one drawback of our model is that you can't comfortably carry the camera/gimbal setup in a low-slung, horizontal configuration. We decided that the solution to this is to add a rigid handle that could firmly attach to the gimbal neck, separate from the spinning head.
I began by measuring the space right beneath the spinning section. The idea was to make a bracket of thick aluminum that would clamp around the gimbal neck and support a 90-degree handle far enough away so it doesn't interfere with the camera movement. Now that I had all the necessary dimensions, I whipped up a 3d model in Fusion 360. Instead of 3d printing this piece or cutting the aluminum with my traditional woodworking tools, I'm going to use a new tool, a waterjet cutter.
A watejet cutter works by shooting a super high pressure stream of water out of a nozzle that is attached to a moving gantry. Like a CNC, but it doesn't cut with a spinning bit, it cuts with water infused with abrasive grains of garnet. Normally these machines are found in large manufacturing setting and take up a huge footprint. But the guys at WAZER designed one that fits on a table top, and they sent me a machine to try out. Not only can it cut aluminum, but it can cut steel, glass, and a lot of other materials that desktop machines can't. Full disclosure, they are sponsoring this project.
I imported my design into the WAZER software and loaded the 1/4" aluminum into the machine. It was crazy to see that raw metal being cut out with a moving stream of water. If you don't have access to such a machine, aluminum can be cut with most woodworking tools. The handle design is simple enough that a bandsaw and a hole saw would work just as well. But if the design were more intricate, the waterjet would be the perfect tool.
My design fits together using two slots, one in the bracket and another in the 90-degree handle. The fit is loose enough that I could TIG weld the two pieces together. I have been wanting to get into TIG welding, it is a different set of skills from traditional MIG welding. Unfortunately, I couldn't get the settings right on my welder and decided to go with another method of joining aluminum, brazing.
To attach the handle to the gimbal, I cut the bracket that would fit around the neck. This gave me a clamp-looking collar that could be tightened around the gimbal with some screws. I used a metal tap to create threads in the bracket and some EVA foam to act as a gasket around the gimbal neck. I also decided to powder coat the aluminum. I used a special powdercoating setup to bond the powder to the arm and then bake it in an oven. This adds a layer of additional protection that is way tougher than paint.
To make the gimbal handle more comfortable in your hands, I needed to add some wooden scales. Similar to knife scales, these wooden pieces would be fixed to either side of the flat aluminum. I glued the wooden strips to the sides of the handle with some CA glue and then drilled some through holes for some pins. Once the scales, the handle, and the pins were all epoxied together, I began to shape the handle on the sanders. I rounded over the harsh edges and added some indexing spaces for your fingers.
Having a 90-degree handle off on the gimbal makes it so much more comfortable to use at all angles. The additional stability is great and being able to make low-slung shots is super cool! Thank you to the team at WAZER for sending me that desktop waterjet cutter. It will really allow us to cut things that we were never able to before.

ILTMS is awesome.
Sure is!
You know you have made it when you have a camera guy filming the camera guy filming you. Another great video
Ha! :)
Nah, he'll have made it when he has a camera person filming the camera person filming the camera person filming him. 😂
The fact that there exists a prosumer-grade water jet cutter like the Wazer that you can install in your home workshop just kinda blows my mind. It may not be cheap but I'm still stunned that it exists AT ALL
1:47 That was very satisfying to watch.
It really was!!
When I got a CNC mill I was quite happy finally I'm nearing Bob's tool chest. Now look at that. He got a damn water jet cutter.
Ive got several 3d printers, a cnc, and just added an industrial sized (6 ft by 5 ft footprint) to my shop and thought to myself "I think I have finally caught up with Bob". Now this video pops up and I invented new curse words :)
i won't be the first one to point this out, but it is a valuable tip to repeat : The tap breaking is from the threads of the tab clogging up , for every 2 half turns clockwise, turn 1 time anticlockwise, that way you turn "out" (eventually) that way you have cut form to hole to create the threads. also even in aluminium, use cutting oil (or wd40) it "flushes" the hole and threads in a way.
Absolutely this. I immediately noticed him driving it all the way in, and I knew it was going to break.
Yeah this blunder is even worse than tapping the screw holes before cutting them in half just to drill out the hole again.
i don't think this is a blunder.
this channel is about learning how to make, and Bob is on that voyage of learning with his audience. it's great that he had the idea to do this and jumped into this project and just did it.
For once i have seen something that i might help him and that is only a little return from all i have learned from him , the channel and the community.
the part of drilling out the whole after tapping isn't that crazy. it's harder to tap a shallow hole than it is a deep one.
the only thing i would suggest regarding to that in a project like this where you want the maximum precision you can, is to use the drill press to drill it out and not doing that with a hand drill. these things are so out of balance, because of the battery and certainly DeWalt is very sturdy, but also (nose)heavy.
(don't know if that is the case with the model bob uses, it's my experience with them)
anyway, you never drill out the hole straight with a hand drill, you'll be much closer with the drill press.
but you have to fix up a jig, to the needs of your drill press and the piece you are working on.
which means time to set up for an other segment that maybe isn't as relative to the story telling and setting up the shots.
and since these guys are producing content on a daily basis, it's easier to grab the the hand drill and probably it is good enough.
i'm trained as a movie maker, i get the hustle there, and the possible irrelevance to the project/audience.
Hi Bob!
Two tips about taping that can explain your first broken tap. Maybe you already know them but in case you don’t it will be my pleasure to share them with you.
First, you need to use tapping oil/cutting fluid. You can get away with simple WD40, but it’s not the best.
Second, you need to break the chips. It’s even more important with small flimsy taps. Anyhow, the technique is pretty simple. Every few turns (this is the experience that will guide you on the number of turns, but if you’re feeling that the tap is flexing a bit more, it’s a good sign), simply unscrew the tap a few turns. You should feel the chip breaking. Then you can continue your tapping. With deep tapped holes, it’s always a good idea, from time to time, to completely unscrew the tap, clean up the tapped hole with compressed air and re-applying some tapping fluid before continuing.
Nice job again! Continue your great work!
The guys who made this went to my school (UPenn) and they just came back to talk about making it. It’s so crazy cool for me to see you with the machine that I saw in person last week
I definitely learned something: I always watch videos with people powder coating but no one ever takes the time to explain how it works. You do a great job of telling the story and not assuming your audience knows the basics.
The first words that went through my mind when you said "Wazer" was: "I could make that if I had $100,000 in tools." I'm glad you took time to address that again at the end of the video.
Excellent video. Thanks Bob.
I like when existing things are augmented to make them better (rather than going out and buying new). The Wazer is pretty cool as well! Great work!
Wazer? First time I have heard of the word... I thought he misspoke.
The WAZER is definitely a sweet addition to the ILTMS shop. I'm thinking there are going to be some awesome prop builds in the future.
Great idea for the wazer. Can’t wait to see more uses for it.
Thanks for sharing the powder coating! May need to try that!
can you make a bits video on powder coating?
We could probably do that
Little tip on tapping: The tap you are using is for through holes, it pushes the metal into the hole. What you are looking for is a bottom tap, it pushes the metal out of the hole and doesn't jam in the bottom.
Love the result! Those transition shots are 😘👌. Hope to see more of them in your videos
Love you videos, especially the camera related DIYs and mods like this one. Keep up the great work!
This was such a great video! I don't really have a need for a gimbal at this time but this video contains a wealth of tips and techniques that can be applied to any project. Well done team!
Really cool guys! Turned out great and works great!
Love the inventiveness and the demonstration
Please use this ALL THE TIME! love these shots!
Great work Bob. I'm never going to make that handle but it gave me plenty of different ideas. Keep up the great work.
Bob, you and your team are just really good at what you're doing. Keep it up, love the videos.
Thank you Torin ! I really appreciate the encouragement!
Thats some super smooth transitions. This just gave me an idea to make a custom gimbal for a phone from scratch. Thanks Bob!
Hey bob I showed my hard materials teacher your tutorial videos for joints and things and he loves them . 😄
I love your work and videos you inspired me to make a fancy dinner table and im only 15 and It succeeded. Your awesome keep it up 😄
This handle has so many practical applications even if you don't have a gimble, nice work!
Great video. Always wondered about diy powder coating. Thanks
Nice work on the Gimbal Bob! Thanks for sharing the video with us.👌😎👍JP
I like this channel because we always learn a new way to do things. Loved the power coating. And I am amazed about the water cutter. Just awesome vídeo.
In this vid and others I learned to use CA glue for temporarily holding items together. Great tips!
This is so cool Bob! I recently had to make a custom piece of camera gear out of Aluminum as well, but I really love your approach here! It looks super slick!
I love how you wrapped up the video standing next to your R2 unit like he’s your co-host.
I don’t know if you did this or not but with the tap using lube helps and turning a few time in the back it out the clear the chips then back in. The chips can grab and cause it to break if they don’t come out.
Great improvement on existing equipment without the need to buy a new equipment. Good job! 👍🏼🙂
Wazer just seem so cool. I’m used to using a very slow (but extremely accurate) wire EDM machine so the Wazer concept is rather appealing.
This is my favorite project of yours so far!!! AWESOME!
One of my favorites too!
Bob when you tap a hole use a thread cutting oil on the tap and turn a half turn forward then turn back a quarter turn and repeat. Doing it this way allows the material you are cutting to back out from the tap's end and binding and subsequently breaking off.
Lol. Wazer. Water laser. Nice. Very dad-jokey. I love it.
tap breaking: every full circle you make with the tap you want to twist it out completely, that way your tap will last forever. it takes longer tho..
You probably already did this but I didn't see it in the video. Cutting oil will help make a cleaner cut and help the tap from snapping off
It helps to back them out but they can still snap easy especially with something as small as 3mm
It snapped because the chips get stuck in the bottom, you need to either drill a deeper hole than you want to tap or use a bottoming tap preferably with a spiral flute to clear chips. Twisting it out all of the way also works but it also increases suicide rates of machinists.
I learned to do one backwards 1/2 rotation for every full rotation to cut the chips off. Backing it all the way out a few times helps clear the channels, but after every rotation seems too often.
Hi Bob, i am studying mechanical engineering and we learn that if you use a thread tap that we should use cutting oil and sometimes turn it back to clear the hole! Hope you can use my advise
Love your way of thinking about stuff
Nice upgrade. It doesn't look out of place. OEM accessorie 👍
Daaaaang. Looks good! Very cool to see the shots at the end. I wasn't thinking there would be that much difference! Kudos to you all :-)
Man, you really went all out on this one. I really liked this one!
Awesome work Bob! 😃👍🏻👊🏻
I didn't know there was DIY powder coating, thanks for sharing!
i never ever thought i would see the day that one can have WATERJET in their homes. DUDE this is EPIC do you know how much MORE you can build now? hope to see much much much more of this thing in future
Idea for the quick release: you could use a hinge on one side of the collar and then a clamp on the other side.
While this would probably require the collar to be thicker and the cut to be directly in the middle of the circle, it would be quicker for sure.
I would like to think I am a maker/photog. Even though a lot of the methods in your video are not new to me, I enjoyed watching your process. I am also very interested in the desktop waterjet, I did not even know these existed 15 minutes ago!
It's amazing how just one more handle like that can improve it that much. Nice job!
Such a great video, reminds me of the old Jimmy Diresta knife videos, such quality content as usual Bob, I love your channel and all the content you produce
That water jet is sweet. I challenge you Bob to do a water jet only video. One where you say “if you don’t have a water jet, this project isn’t for you, but let’s just appreciate how cool this tool is!”
You started where we all did and you’ve earned this amazing tool with your hard work. Haters gonna hate. Trollers gonna troll.
Nicely done,beautiful job
Nice Maker Knife Bob! Love mine!
This is super cool, thanks
well done boys!
This is an awesome build.
Neat project! I love being able to make the things we want instead of having to buy them.
You could add a half ring to the handle side, mounting it above the current clamp. Hold it in with a few tapered screws and it would stiffen up the grip (twice the current thickness).
Nice machine.
Very nice work there.
That is pretty slick. Now you have a "poorman's steady cam" very nice job.
Huge fan of the channel! I also own that same gimbal and this would come in handy. (Side note) Please consider making a video on "Smart Blinds"! Besides ready made products costing an arm & leg, there are virtually no vids on them. With your experience in servos and automation, I'd LOVE to see a video with you making smart blinds and explaining your methods :)
i like your videos for one reson because you make everything simple as you can as possable...greetings
If you are using a tap that small, it is often a good idea to go two turns in and one turn out to relieve some of the pressure. That way some of the chips have a chance to get out of the hole. That is something that I learned when taking metal shop. Other than that, I love the video!
Always use cutting oil when you tap a hole. you should also use a tap with a twist for deep holes or back it out often to break and clear the chips.
watching you work, the thing I notice that I need to incorporate more is that it's okay to take multiple steps to achieve one goal. case in point, tapping the whole length of those M3 holes and then removing the threads of the top piece... I'd have probably wasted a lot of time measuring and trying to drill my clearance holes to the desired depth before even busting out the taps.
TALENTED !
My understanding when tapping was that you tap the tread a turn or two then back it out a half turn or so then continue ( to stop excess build up of heat and swarf) didn't appear to be doing that in the video. Could be a contributing factor to the broken tap.
That Wazer is awesome!
Well done and like how you thought outside of the box.
Interesting! Neat project and a very cool tool!
Wow from your videos I learned so much thanks for everything
Very interesting. Good job
Good stuff!
Tip for tapping a threat: use a little drop of cutting oil on the tap and turn it one turn clockwise then half a turn counterclockwise. Then you'll tap won't break of :)
Love it, I've learned so much by watching your vids! Btw, would love to have Wazer. :)
Wow just wow🥳🥳🥳🥳🥳🥳
Very innovative
Cool project!
Very Cool Handle Sir
Sweet video!
Bob, thanks for another great video. While grinding aluminium please be aware that aluminium dust is dangerous for lungs, actually more dangerous than steel sparks, so it would be better for you to have some kind of breath protection or at least just keep your head away from where the dust comes, just as you did on the video :)
Nice handle, I like it, good job.
Bob is going TIG? Wooow been waiting a long time for that!
Great video Bob! I see you got your Maker Knife!
nicely done..
You are great, really you have a scientific thinking
Fantastic job, dude. Really well done! 😊
It'll be interesting to see if you have issues with the threaded holes stripping out over time. FWIW, we typically use helicoil inserts with aluminum to avoid this issue for the commercial work we do. That being said, if you're not taking it on and off, you might not see an issue. Overall, great design and video!
Love your vids 👍
The tap will always work best (and is less likely to snap) when used with a cutting oil. Less friction, less binding, easier action.
Awesome!
Fantastic! I actually forgot about brazing aluminium.
Bob has a lot of different kinds of machines now, its crazy how he's grown
Very cool!! :)
A future project idea for you Bob...
...A full Campervan conversion, from the ground up (a Volkswagen would be my personal vehicle of choice but any van would do for the video to show the practice).
Custom furniture, lighting, plumbed in stove/sink units, electrical elements (sockets, site hook up, solar power, tv...etc)
i loved the powder coating technique of yours, would love to know more about it.
sendcutsend is a great laser service that will also cut these sorts of things if you need something precise. home waterjet seems amazing! i'll put it on the list right below shop laser.
I learned how to make a raspberry noise with my mouth!! Praise God for outtakes 😊😂😆😁
Shout out the the WAZER crew! Coolest people around :)
