Two things for working with epoxy: 1: Masking tape is your friend. For running the wires up the tube, a strip of tape on either side of the wires would keep excess off the surface. Additionally the tape could be used as a guide for your forming tool. 2: If you want to use a filler such as Kevlar powder in your epoxy but don’t like the rough surface, wait a bit for the epoxy to set up after shaping, then wipe it down with some denatured alcohol to smooth the surface. Wait for the epoxy to be stiff enough to stay in place, but still soft enough to be shaped. The alcohol softens the surface slightly allowing it to move more. Just using your gloved finger, wet with alcohol, will make the surface nice and smooth. This is a common practice in boatbuilding fillets.
A friend of mine worked for Saab and they found out the hard way that CA can interfere with electrical connections on the JAS 39 Gripen aircraft. As far as I know its safe to pot a wire with it however its imperative to keep it far away from connecters or contacts. Given the cost and complexity of my work learning this forced me to rethink how I used CA in the future. Keep up the great work! You do things that are inspirational. Thankyou...
To be fair to his stupidity I'm pretty dumb myself and as soon as I saw him gluing those exposed wires to carbon I was screaming at the screen. Reminds me of my favorite quote “Mankind is made of two kinds of people: wise people who know they're fools and fools who think they are wise.” - Socrates
So, he might be, because he dug out the leads, and covered them in CA, instead of like, using heat shrink. The CA will crack up under vibrational loading in flight, short out, and wheeeeeeee. Just use the bloody heat shrink, my dude. You will save yourself the tears.
@@arfink -- It's encased in epoxy now, as long as there's a physical barrier between the CF and the wire, the physical strength shouldn't matter. Laying some epoxy in the grove before adding the wires might end up stronger though.
I love the "Oh Woooooowwww" moment with the CF. That moment you realize you're thinking on level 8 but something at level 2 smacks you upside the head like "Hey DUMMY! Remember this??"
Carbon fiber dust can accumulate in wall outlets, power tools, and electronics causing shorts and destroving equipment .

Having designed composite parts at my job I couldn't help but cringe at seeing him machine composite laminate. He would need an autoclave, but the right way to make those fins is to lay up the plies on a tool to shape and cure under pressure. But he's not set up for that.
Great video! You might want to try adding a thixotropic agent (colloidal silica powder) when mixing epoxy for the fillets. It turns the resin into a gel-like form that won’t drip and holds its shape. This way, you wouldn’t need to wait an hour or more for the resin to hold its shape. Trust me, thixotropic agent is fantastic-you could even make a snowball-sized blob of epoxy and stick it to a wall! 😄 Thanks for the video!
15:23 careful with those bare soldering points; carbon fiber composites are highly conductive LOL 16:40 one minute later you found out. Very attentive my man!
I used to build a lot of drone frames on a cnc router and really liked doing it underwater, the finish was great and it was soooo quite too. It takes a bit of work to get a good system for doing it underwater though. I found a place that made semi custom stainless appliance drip trays. Got the biggest size that fit on my machine, and I bolted an aluminum t slot table down to the frame through the tray and sealed the holes with o-rings between the tray and my machine frame. This provides a nice solid surface you can attach to in various ways. Surprisingly the tape I used held up fine for a few hours under water. Add a drain to the tray and you are in business. Thanks for the distraction tonight!
I've also cut carbon fiber parts underwater on a CNC router, and I just used a cheap thin baking tray. Drilled some holes in the carbon fiber and wasteboard material, and screwed through the carbon - wasteboard - baking tray stackup into a secondary MDF wasteboard. Worked well.
Are there any effective wet sanding techniques that don't require putting the entire vehicle under water? Quite a few sanding steps were done after assembly.
I made mine out of the vinyl drip mats used for showers.... just lined a table that had a 4 inch lip and set the machine in there. , then put some splash guards up..... double filtered.

I totally enjoyed this video as it felt more casual and personal. Sharing the good and bad works on many levels. Obviously we too can learn from your mistakes, but they also make you more human and relatable. Been there, done that. Keep up the great work, and stick with your safety protocols. Given the flammable chemicals and paints you have, you may want to consider a flammables cabinet. I kept watching auctions to pick one up much cheaper than new, and got lucky with a like new cabinet.
Common power and ground could be used for the servos and the carbon could be utilised as the common ground. A copper mesh can be epoxied onto the carbon tube to attach the ground wires to. This would reduce the number of individual wires from the controller to the servos from 12 to 5. Maybe overkill at this point but if you have more components needing ground it would become more valuable to use the chassis as a ground and reduce the amount of wiring.
Also, why not use heat shrink to isolate the wires from each other and the carbon fibre? That's pretty commonly how it's done for other non-recoket projects.

Years back the xjet channel mostly did videos on pulse jet engines. He decided he could make a pulse jet guided rocket and started working on it. The US government did not like the idea and called it a cruise missile, Enough pressure was put on New Zealand by the US that they banned his research. In the end he had to remove his all of his content off the internet and now only does r/c flying and drone content. Just a heads up, what is a hobby to one person may be considered a weapon by those in power.
A couple of other youtubers have run into that. Seems to be, as long as there is no way for the rocket or pulse jet to be guided, they are left alone. Xjet was more or less okay until 911 when there was a purge on available information on the internet (before then there were detailed blogs regarding pulse jets and other things).
Joe has already been running into these issues. Certain information we'd love to know is left out or blurred in past videos to prevent crossing into FBI investigation land.
JoeyB out here with some high quality sponsors, love to see it!! I was really concerned to see those exposed servo leads touching carbon, but hilarious when you figured it out! Awesome work as always!
It's easy to admire the feats of engineering that SpaceX are accomplishing....... but I think I have even greater admiration for the Solo Engineer aiming for the vacuum. Bon chance!
At 3:25, That's a funny microphone you got right there. Must be some cool new technology! Edit: as I watch the video, your idea of what counts as a microphone astounds me
Lavalier microphone clipped to something to hold onto. Could just wear the thing as intended, but sometimes you get better sound by holding it. And buying a handheld microphone is more money not spent on rockets…
This gonna be epic! And a small advice, one of the very first things that I’ve learned at the engineering school: Every time you cut and solder an extension cable you need to seal it with termofit or any isolation method, in order to prevent shortcuts, discharges, electrical noise on the signals, etc, in this case this could result in a short cut of those expensive servos, and every penny counts.
Great video again!! From one hobbyist to another, we typically embed a bronze(oil-lite) bushing into the carbon, then your pin is a precise fit into the bushing. This way you get minimal back lash and smoother operation. Cheap bronze stock from our McMaster friends 😉
I'm not a rocket enthusiast and certainly not a rocket builder, but I enjoy your videos. But I was a little disappointed that there was no actual rocket going at mach 3 at the end! OK, the title did say "building", but I naively thought - why build if you're not going to fly? Still, it was interesting, and even made me laugh in places (plus I had no idea carbon fibre is conductive!). The only downside is that I can't get the 'smell' of epoxy out of my head now!
Trump came in at just the right time to block America from having a female president for the only two attempts. He’s like a bouncer. Last year I voted for biden but this year proudly trump.
For future builds, consider heat shrink over the solder joints, and also crimp the connectors onto the leads *after* they go through any holes (that allows drilling much smaller holes).
I am a mechanical design engineer and design automated manufacturing equipment. Servos are how we get precise position, speed, and torque control. This is really so cool to see you applying all this to the rocket. I have learned a tremendous amount from this. Thanks. This is awesome.
Hey Joe, I know from robotics that those servos sometimes have a really bad thermal conductivity inside the housing If you can manage to machine the housing to add a screw fill port, you can flood them with clock makers oil. We used to do this on the high performance robotics servos for competition. Definitely try it on a damaged servo first though, we had a different model of servo that just died immediately when flooded.
Hey Joe, I am a huge fan of your channel and I have to say that I really love these longer format videos where you go much more into detail about your builds. Keep up the amazing work!! :)
EPIC VID! as someone who works with carbon on a daily basis, please wear sleeves for your own sanity!! Carbon dust causes tons of skin irritation, often worse than fibreglass or other composites. A sleeve or dust protection cream would prevent this, and make sanding a much less painful process. Thanks for the vid!!
I would just like to thank you for producing such high-quality videos. It is unbelievable how much effort you are putting in. I studied aerospace engineering and this video shows what these studies are meant for.
Great video! Enjoyed every minute! I have several suggestions for future builds: 1). Ditch the Box Store drill bits. A suggested source is SMA Direct. Also, cobalt drills for carbon fiber! They can be sharpened sharper than the coated bits I recall you were using. American or Japanese manufacture. 2). Fillets. Mount tube in lathe. Once fillets are formed rotate tube to even out the gravity's effect. 3). Cable raceway 's. Tube mounted in lathe, use carriage to smooth and index raceway. Withdraw cross slide, and spin. 3). After all carbon fiber work, cover entire vehicle with 0.7 ounce glass if weight is a concern, 2.0 if not, as 2 oz is easier to work with. Round areas, probably including raceway areas use sock glass to eliminate joints (I don't know if socks are readily available in small quantities) 4). Use an automotive body/paint filler to cover imperfections. 5). On copper nose cone, put a pointed spire to move shock wave away from your steak. Look at early Polaris, Trident, and most Soviet missiles for examples. 5). While machining carbon fiber, cover as much of the machine as possible with double sided tape. Cover all electrical outlets and switches as well. Cover with painters tape first, and remove both tapes when finished, after cleaning work area! Carbon fiber seems to be attractive to electrical and WILL cause problems. I don't know what threshold is so be careful! I have enjoyed your content for a number of years. {Key word and tricky phrase) SEMPER FIDELIS BOB
When potting the cables along the length of the body you could use a indexing notch on the printed form squeegee and line up a vertical laser level along the run of wires to have a guide as you do the pull.
@@CBWP That's not accurate. I've worked on the GMLRS guided rockets at LM in Precision Fires, specifically the M30 and M31 guided rocket munitions, as well as the ATACMS and PriSM. They two terms can, and are, used interchangeably.
Awesome video and commendable effort. A possible suggestion when soldering the servo motors is to use heat shrink to insulate the wires for a better piece of mind that the solder won’t break or the connections won’t short.
Hey man! I love your video's, super creative and fun to watch. I dont know why my silly mind is commenting this, but u could use a spinning wheel on the end of each fin to make it spin when its going fast. So when the rocket goes up, gets more speed, the wheel starts turning really really fast.. that makes an gyroscopic effect to make the rocket stabilize itself. It's used on the Aim-9 sidewinder missle, if u search it up u would probably find it.. Dont know what u can do with this information, but i thought it would be cool.
A tip I learned cutting EPS foam cores for an aerospace company I worked at: instead of running your parallel/raster toolpath along the fin edge, run it across and use a square tool instead of a ball. You'll maintain surface footage out at the major diameter of the square tool versus significantly less cutter speed closer to the center like a ball endmill would deliver.
Really appreciate you sharing all the wins and fails (learning experiences!) as you do this, Joe! Ad astra per aspera. And you really do make excellent videos 👍
I know cf is conductive but I also didn't realise you going to get a short. It's just that cf doesn't look conductive, so it's easy to forget it actually is. If you would have a shiny metal fins, you would realise right away you going to get a short.
I’m so glad that was a pure passion project video for you ie, “no effort”, because that was amazing. Clearly your video skills are at an amazing level now. Or I’m just easy to please!😂
I fully thought this video was less than 42 minutes felt like 15 I swear, nice vid love learning about these things, I really wanna get into model rocketry
To made a down draft work surface . Make a rectangle wooden box, with one side made from peg board. On the side of the box make a hole for the shop vac. This create vacuum under the sanding surface. Good also for painting, to keep dust off. Wish you the best in your endeavors. 🎉
31:24 you can use heat shrink sleeves , that is more clean than an electric tape , but there must be a reason why you are not using it. Any ways luv you Joe, Appreciate your patience and passion for rockets. Best of luck🤞
For the fillets, have you considered making a silicone mold? Silicone will leave a clean and smooth surface finish, you can use your kevlar mixed into epoxy and still end up with a good finish. The creation of the mold would probably take some time but offset the amount of wiping and cleaning while also reducing waste. The mold will also be highly reusable.
1) you're not stupid, but I was honestly surprised you didn't insulate the servo connections against the carbon fiber haha. I was like ok.. "he's going to hot glue the connections or something right? " Awesome video, keep up the hard work looking fwd to the space shot and beyond!
Those giant paint cans can have the tip swapped out with a regular tip if you didn't know. I use an air powered sander for fiberglass as its completely water proof so working under a sprinkler will keep the dust contained.
"You can be killed by an Estes park flyer." I had a little Estes R2D2 rocket fail to ignite once. I didn't know what was happening and walked up to it. It ignited suddenly, when I was about to bend over and pick it up. I felt the heat of the exhaust on my face, but wasn't close enough to be burned. I learned a LOT about safety from that one experience.
I did have a couple of thoughts watching the build. when you epoxy the servo horns onto the tabs, it would probably be easier to do them first and let them cure before you attach them to the servos. Also just use some heat shrink tubing on the servo wires.
IDEA: To save time on mixer cleanup, could you 3D print disposable covers for your mixing paddle? And / or spin cast a flexible, removable silicone liner for the bowl that you can pull out and flex to break off the cured material?
Sir, i think we have very different definitions of "No effort". This is top quality.

HHAHAHAHAHAHAH AGREEEEEE... this dude is amazing.
Two things for working with epoxy:
1: Masking tape is your friend. For running the wires up the tube, a strip of tape on either side of the wires would keep excess off the surface. Additionally the tape could be used as a guide for your forming tool.
2: If you want to use a filler such as Kevlar powder in your epoxy but don’t like the rough surface, wait a bit for the epoxy to set up after shaping, then wipe it down with some denatured alcohol to smooth the surface. Wait for the epoxy to be stiff enough to stay in place, but still soft enough to be shaped. The alcohol softens the surface slightly allowing it to move more. Just using your gloved finger, wet with alcohol, will make the surface nice and smooth. This is a common practice in boatbuilding fillets.
Also, for getting a good bond to aluminum, hit it with some coarse grit sandpaper.

A couple of other youtubers have run into that. Seems to be, as long as there is no way for the rocket or pulse jet to be guided, they are left alone.
Xjet was more or less okay until 911 when there was a purge on available information on the internet (before then there were detailed blogs regarding pulse jets and other things).
Didn't he call it a DIY cruise missile though? Lol, I love Xjet he's a legend in the hobby.
Joe has already been running into these issues. Certain information we'd love to know is left out or blurred in past videos to prevent crossing into FBI investigation land.
JoeyB out here with some high quality sponsors, love to see it!!
I was really concerned to see those exposed servo leads touching carbon, but hilarious when you figured it out! Awesome work as always!
Great video Joe. I always appreciate your transparency and honesty in the design process, makes it much more interesting!
Awesome video! We are happy to hear Xyla was able to provide you some epoxy tips :)
It's easy to admire the feats of engineering that SpaceX are accomplishing....... but I think I have even greater admiration for the Solo Engineer aiming for the vacuum. Bon chance!
Definitely! What he has accomplished and continue to do for one person is simply astounding. Massive respect for his tenacity!
very fire my dood, i like. try out heat shrink tubing for your wires, unheatshrinked solder joints on a wire make my eyes itch sometime
That’s the first thing I’ve thought about
At 3:25, That's a funny microphone you got right there. Must be some cool new technology!
Edit: as I watch the video, your idea of what counts as a microphone astounds me
Lavalier microphone clipped to something to hold onto. Could just wear the thing as intended, but sometimes you get better sound by holding it. And buying a handheld microphone is more money not spent on rockets…
This gonna be epic! And a small advice, one of the very first things that I’ve learned at the engineering school: Every time you cut and solder an extension cable you need to seal it with termofit or any isolation method, in order to prevent shortcuts, discharges, electrical noise on the signals, etc, in this case this could result in a short cut of those expensive servos, and every penny counts.
Hurray for another BPS video... and this one is 45 minutes? Rock On! loving no-effort-november so far!
Great video again!! From one hobbyist to another, we typically embed a bronze(oil-lite) bushing into the carbon, then your pin is a precise fit into the bushing. This way you get minimal back lash and smoother operation. Cheap bronze stock from our McMaster friends 😉

I'm not a rocket enthusiast and certainly not a rocket builder, but I enjoy your videos. But I was a little disappointed that there was no actual rocket going at mach 3 at the end! OK, the title did say "building", but I naively thought - why build if you're not going to fly? Still, it was interesting, and even made me laugh in places (plus I had no idea carbon fibre is conductive!). The only downside is that I can't get the 'smell' of epoxy out of my head now!
Sweet, sweet relief
Trump came in at just the right time to block America from having a female president for the only two attempts. He’s like a bouncer. Last year I voted for biden but this year proudly trump.
Oh how I needed this.
For real. I can actually feel my brain turning to mush right now. Needed a little science tonight
yeah with all bad s*** going on now that’s a blessing ❤
A tiny raft in a tumultuous sea
For future builds, consider heat shrink over the solder joints, and also crimp the connectors onto the leads *after* they go through any holes (that allows drilling much smaller holes).
YESSSSSS! YOU FINALY HIT MAC 3, CANT WAIT FOR IT GO TO SPACE
I am a mechanical design engineer and design automated manufacturing equipment. Servos are how we get precise position, speed, and torque control. This is really so cool to see you applying all this to the rocket. I have learned a tremendous amount from this. Thanks. This is awesome.
Just waiting for the day this channel goes dark and we never find which 2nd world countries rocketry program BPS is heading.
Hey Joe, I know from robotics that those servos sometimes have a really bad thermal conductivity inside the housing
If you can manage to machine the housing to add a screw fill port, you can flood them with clock makers oil. We used to do this on the high performance robotics servos for competition.
Definitely try it on a damaged servo first though, we had a different model of servo that just died immediately when flooded.
29:29 - I was all “no he dint!” Then I ran it back and was like “Daaaaaaaamn!” 😂😆🤣
Boeing moment 😂
@@bowlerballer6852Titan moment😂
I wish more engineering channels would do more deep dives like this. For people trying to learn engineering these videos are crucial imo
thank you very much for your nerdy rambling
Hey Joe, I am a huge fan of your channel and I have to say that I really love these longer format videos where you go much more into detail about your builds. Keep up the amazing work!! :)
EPIC VID! as someone who works with carbon on a daily basis, please wear sleeves for your own sanity!! Carbon dust causes tons of skin irritation, often worse than fibreglass or other composites.
A sleeve or dust protection cream would prevent this, and make sanding a much less painful process.
Thanks for the vid!!
Absolutely love the technical deep dive ❤ gave me a few ideas how to change up my rocket 😁 thanks man!
Technology Connections is one of my favorites!
This series is gonna be good.
Mach 3 got hands - this is a shirt
I would just like to thank you for producing such high-quality videos. It is unbelievable how much effort you are putting in. I studied aerospace engineering and this video shows what these studies are meant for.
Great video! Enjoyed every minute! I have several suggestions for future builds:
1). Ditch the Box Store drill bits. A suggested source is SMA Direct. Also, cobalt drills for carbon fiber! They can be sharpened sharper than the coated bits I recall you were using. American or Japanese manufacture.
2). Fillets. Mount tube in lathe. Once fillets are formed rotate tube to even out the gravity's effect.
3). Cable raceway 's. Tube mounted in lathe, use carriage to smooth and index raceway. Withdraw cross slide, and spin.
3). After all carbon fiber work, cover entire vehicle with 0.7 ounce glass if weight is a concern, 2.0 if not, as 2 oz is easier to work with. Round areas, probably including raceway areas use sock glass to eliminate joints
(I don't know if socks are readily available in small quantities)
4). Use an automotive body/paint filler to cover imperfections.
5). On copper nose cone, put a pointed spire to move shock wave away from your steak. Look at early Polaris, Trident, and most Soviet missiles for examples.
5). While machining carbon fiber, cover as much of the machine as possible with double sided tape. Cover all electrical outlets and switches as well. Cover with painters tape first, and remove both tapes when finished, after cleaning work area!
Carbon fiber seems to be attractive to electrical and WILL cause problems. I don't know what threshold is so be careful!
I have enjoyed your content for a number of years. {Key word and tricky phrase)
SEMPER FIDELIS
BOB
When potting the cables along the length of the body you could use a indexing notch on the printed form squeegee and line up a vertical laser level along the run of wires to have a guide as you do the pull.
5:05 "What if we tried using more power?"
I love that you explain the time-consuming steps too. ❤
Man I love Bepis Space Time
Just continuity tested my EDC's CF scales.... BBBEEEPP! Wow, should've know that!
Not a missile though, right? RIGHT?!
„The Missile knows where it is, because it knows where it isn’t“
All things with guidance switch from rockets to missiles...
Yep, it's an SCGM. (Steak Cooking Guided Missile)
@@CBWP That's not accurate. I've worked on the GMLRS guided rockets at LM in Precision Fires, specifically the M30 and M31 guided rocket munitions, as well as the ATACMS and PriSM.
They two terms can, and are, used interchangeably.
@@bryanhoppe1481 ok "normally" rockets are not guided. They seem to have to have a name that forms a good acronym as well.
And just like Alec, you have turned No Effort November into a big video with a lot of effort. Way to go!!
I'm enjoying the wide variety of mic stands. Oh and the rocket is nice too.
Joe, your engineering skills are outstanding, especially your testing along each step to ensure viability. Keep up the great work!
To be honest.... on a day like today, a long deep dive into making rocket airframes is EXACTLY what I need - thank you
Fbi I think you need to watch this man😭
Awesome video and commendable effort. A possible suggestion when soldering the servo motors is to use heat shrink to insulate the wires for a better piece of mind that the solder won’t break or the connections won’t short.
Well crafted video! Nice flow and pace. I subscribed.
Hey man!
I love your video's, super creative and fun to watch.
I dont know why my silly mind is commenting this, but u could use a spinning wheel on the end of each fin to make it spin when its going fast.
So when the rocket goes up, gets more speed, the wheel starts turning really really fast.. that makes an gyroscopic effect to make the rocket stabilize itself.
It's used on the Aim-9 sidewinder missle, if u search it up u would probably find it..
Dont know what u can do with this information, but i thought it would be cool.
A tip I learned cutting EPS foam cores for an aerospace company I worked at: instead of running your parallel/raster toolpath along the fin edge, run it across and use a square tool instead of a ball. You'll maintain surface footage out at the major diameter of the square tool versus significantly less cutter speed closer to the center like a ball endmill would deliver.
Really appreciate you sharing all the wins and fails (learning experiences!) as you do this, Joe! Ad astra per aspera. And you really do make excellent videos 👍
36:36 YES those free-standing hammocks are great!
I know cf is conductive but I also didn't realise you going to get a short.
It's just that cf doesn't look conductive, so it's easy to forget it actually is.
If you would have a shiny metal fins, you would realise right away you going to get a short.
Joe! You're using drilling guides like I've been trying to get you to do for YEARS
I’m so glad that was a pure passion project video for you ie, “no effort”, because that was amazing. Clearly your video skills are at an amazing level now. Or I’m just easy to please!😂
I fully thought this video was less than 42 minutes felt like 15 I swear, nice vid love learning about these things, I really wanna get into model rocketry
You sir are an inspiration to us all, through both the successes and possibly even more so through your minor setbacks!
I work designing and building UAVs, and when you put the unshielded servo cables onto the CF fin, I was screaming at the monitor "Noooo!" :)
Please do way more like this! This video is great!
To made a down draft work surface . Make a rectangle wooden box, with one side made from peg board. On the side of the box make a hole for the shop vac. This create vacuum under the sanding surface. Good also for painting, to keep dust off.
Wish you the best in your endeavors. 🎉
It was a delight to meet you!
Hecking hero, always a nice surprise! Endlessly engaging. Lookign forward to the next! Best,
Safety tip. Use a respirator when you spray paint. Even if youre outdoors
31:24 you can use heat shrink sleeves , that is more clean than an electric tape , but there must be a reason why you are not using it.
Any ways luv you Joe, Appreciate your patience and passion for rockets. Best of luck🤞
For the fillets, have you considered making a silicone mold? Silicone will leave a clean and smooth surface finish, you can use your kevlar mixed into epoxy and still end up with a good finish. The creation of the mold would probably take some time but offset the amount of wiping and cleaning while also reducing waste. The mold will also be highly reusable.
36:30 Some guy: Oh I wonder what my neighbor is doing on such a lovely day... BPS: *Sanding a rocket frame, mumbling to himself.
I screamed so loud when you glued in the blank solder joints onto the carbon.. XD
1) you're not stupid, but I was honestly surprised you didn't insulate the servo connections against the carbon fiber haha. I was like ok.. "he's going to hot glue the connections or something right? " Awesome video, keep up the hard work looking fwd to the space shot and beyond!
One of my best friends while soldering is heat shrink tubing to get you the electrical isolation and wire wrangling.
Those giant paint cans can have the tip swapped out with a regular tip if you didn't know.
I use an air powered sander for fiberglass as its completely water proof so working under a sprinkler will keep the dust contained.
I was waiting for you to remember that carbon fiber is conductive. I'm glad you tested along they way.
honestly, this is exactly the type of video I allways looked forward to, but never really got.
It allways felt like I was missing out on something
Your attitude towards non-problems is very Kelly Johnson. I love it.
"You can be killed by an Estes park flyer."
I had a little Estes R2D2 rocket fail to ignite once. I didn't know what was happening and walked up to it. It ignited suddenly, when I was about to bend over and pick it up. I felt the heat of the exhaust on my face, but wasn't close enough to be burned. I learned a LOT about safety from that one experience.
The orbit gum microphone defines exactly what this channel is. I love it.
I did have a couple of thoughts watching the build. when you epoxy the servo horns onto the tabs, it would probably be easier to do them first and let them cure before you attach them to the servos. Also just use some heat shrink tubing on the servo wires.
I LOVE technology connections! One of my favorite channels.
IDEA: To save time on mixer cleanup, could you 3D print disposable covers for your mixing paddle? And / or spin cast a flexible, removable silicone liner for the bowl that you can pull out and flex to break off the cured material?
Awesome vid, thanks! More like it please!
