I Upgraded My Ball Vise

[@Sheevlord]

Pre-existing rust shouldn't cause concrete to crack. Cracks occur when the steel that's already inside the concrete starts to rust, because rust takes up more space than the steel did before rusting, which causes expansion. It shouldn't happen if you keep the concrete base indoors, but if you're worried you can seal the concrete using special sealer that would prevent more moisture from entering through the porous surface.

[@davidbrennan7422]

You don't need to worry about the steel inside the concrete. concrete is an alkaline material which creates a passivation layer on the surface of the steel. Since your concrete isn't stressed, it's unlikely to form cracks which will allow water to get in and damage that passivation layer and cause corrosion of the steel. If you're really worried about it, you could paint it with some regular lyx pint something similar to waterproof the exposed surfaces

[@Zakupla_Builder]

Exactly. Rusty concrete is used in the construction industry as the increased friction increases its effectiveness in reinforced concrete members. As stated by another comment, the alkaline environment will inhibit rust progression.

[@conorstewart2214]

@@davidbrennan7422 the concrete is just there for weight anyway, you could just use sand or gravel too, so cracks in the concrete don’t really affect its use. Also in this application water getting in likely isn’t too much of a concern anyway.

Add exhaust fan attached to an adjustable arm to help pull the smoke away from your face as you work. I'm thinking a simple PC fan. You could feed it to a hose duct to route it out a window. Have the option to flip the direction of the fan so you can have something cooling you off while you work.

[@conorstewart2214]

It is very easy to make a simple filter system too, just use a PC fan with a cheap carbon filter in front of it. Maybe add a HEPA filter if you really wanted. A carbon filter is all you need for something like soldering.

[@GGCannon]

How about adding a few strong small neodimium magnets to the halfsphere surface all with the same polarity and one strong big neodimium magnet of the opposite polarity to the base? That would make the sphere "lock" in place with the base and allow you to get much steeper angles of holding it in place.

[@davidbrennan7422]

It looks like you're using a screw and a series of depressions around the perimeter of the rotating bearing to lock the bearing in place, which I think is a good idea. I wonder if you could create an adjustable friction mechanism by having a plane bearing surface and a low friction or medium friction surface like a piece of felt that you could adjust with the screw to create an adjustable resistance rotation rather than simply a stop.

[@KarasCyborg]

If you didn't like the cement and nails, maybe use some resin and some blued steel or copper shavings, and some crystals and make some Organite. Might make a difference. Lots of great ideas in your design. I was really looking for a Turret Camera Housing, but this caught my eye as something worthy to study. Thanks for your work!

[@CusterSurvivors]

I have been working on parts for this very thing. This is crazy. I went modular at first. Tip: Cannibalize from stop-motion armatures, 3d printer frames, etc. Robotic arms are spendy. I'm going to shut up and watch your video now. I can't believe this. By the way, my project started as a way for people with essential tremors to reengage in their hobbies. Whittling, airbrush, stenciling, painting. My therapist is going to love your video!!!

[@ericmorriscompany9648]

I used a shot put ball to make chasing balls. The Olympic official weight is 7.2kg but you can buy training versions in heavier or lighter. They are right cast iron so they need to have the entire outer surface ground and sanded smooth. And you will need to machine a flat face. There is a hole drilled to adjust to the desired weight that can be used for fixtures.

[@erggml1887]

If you live in an area where reloading supplies are a thing you can get, lead birdshot for shotguns would be significantly easier to mix and pour into the concrete. The birdshot are small lead spheres, so mixing will be even easier than the wheel weights. Additionally, the birdshot is smaller in size than the wheel weights and can simply be mixed into the concrete prior to pouring. Alternatively, you might look for tungeston powder, heavier than lead and even easier to mix into concrete.

[@anon_y_mousse]

I feel like this should be a project that every maker takes on.

[@TheChillieboo]

awesome development ! love seeing that iterative process bear fruit. Great work!

[@Guds777]

When rusted metal is covered in concrete it will stop rusting and it will not crack the concrete, lack of steel reinforcement and thermal expansion will crack the concrete. If the concrete layer is to thin around the steel, water can get to it and make it rust. Although steel’s natural tendency is to undergo corrosion reactions, the alkaline environment of concrete (pH of 12 to 13) provides steel with corrosion protection. At the high pH, a thin oxide layer forms on the steel and prevents metal atoms from dissolving. This passive film does not actually stop corrosion; it reduces the corrosion rate to an insignificant level. For steel in concrete, the passive corrosion rate is typically 0.1 µm per year. Without the passive film, the steel would corrode at rates at least 1,000 times higher...

Your shot of the Bunnings bolt section gave me PTSD. So many times I've done a 12 hour print, ducked down to Bunnings, and realised I'm gonna have to redo the print to compensate for their poor inventory management :)

[@conorstewart2214]

When soldering, especially when up closer to your face, make sure you wear glasses or goggles. All it takes is the flux to spit and it could end up in your eyes which is not very good for them. Also a good upgrade would be an extractor fan. Any fan, most commonly a PC fan, plus a cheap carbon filter will suck the fumes away and get rid of them.

[@chettiarsirusraj9501]

A vibrating pen or rod from amazon would be a great tool to have if you intend to do more future projects with concreate since it will seal the concreate surface better and make it less brittle or powder like when it's dried up. The concreate will be more uniform when drying up rather then full of air bubbles as it is dried up.

Such a wild and nifty holder, really awesome design! Found you on the printables page for this and you earned another subscriber after watching the video!

[@thedabblingwarlock]

Re: Rust Cracking the concrete - I'd take a look at Practical Engineering's videos on concrete and rebar and Colin Furze's videos on his tunnel/bunker/underground garage build. The reason rust cracks concrete is because the steel used expands when it rusts. Not a lot, but enough to ruin precision surfaces and cause concrete to crack due to the fact that concrete is great in compression and terrible in tension. If you put something that's already rusty into the concrete and completely cover it, then it won't continue to rust, which means that it won't expand, which then means the concrete won't crack. If I'm remembering right, concrete can also react with rust while curing to prevent the steel from rusting further. I'm not 100% sure I have that right and even if I do, I don't know what chemical reaction is happening to do that. But, the TL;DR: is that you probably don't have to worry about the concrete cracking.

[@conorstewart2214]

Rather the recutting the threads and using nuts you could just screw directly into the plastic. It holds perfectly fine but only lasts a few times being screwed or unscrewed.

[@conorstewart2214]

The concrete isn’t really structural and is just there for weight so cracks shouldn’t really matter, you could do the same just filling it with gravel or sand.

[@dankcincy]

I absolutely LOVE this project!!!

[@matthewmathis62]

Considering you've advertised your invention on KZbin. I'm sure you could get at least a few sales for this on Etsy (or even eBay). -But pretty cool! It seems like this is something that would really benefit from being made with metal. Considering that you are working with things that are heavy (but maybe not, idk what all it's used for). Nice job!! :)

[@WoLpH]

For the dovetail it would be nice to have a camlock to very quickly lock/unlock it for fast swapping of options. That might work for other parts too :)

[@EnezReyiz]

[@mathis.1405]

this is a great idea! i am currently making this and i don't quite get why it is necessary to print the dove tail and the vise adaptor plate seperate instead of making it one print. In the end they are glued together anyways and the nuts could be inserted through the dovetail too, right? Am i missing something?

[@haka8702]

The big ball needs a way to change tension in my opinion, from soft to locked. Also the vise itself, at least the gripper should be metal. I can see my clumsy fingers destroying or melting the plastic grip or base. From that apart, I'd pay quite a bit for a set like that (prebuilt). A hundred $ would be fine imho.

[@patrickjoyce8355]

A note on weights. When I made a ball telescope, I needed a counter weight and I used BBs in epoxy. BBs and cement would probably be even better. It’s a good source of mass that can be acquired new at a relatively low price.

[@jakobhansen1396]

Concrete engineer here, as long as the rust is not loose (DK gravrust) the alkalinity and minerals in concrete attacks the rust and create a seal bonding tigthly around the steel protecting it from further corrosion. Any plating with zinc (or loose rust) will also be attacked but seperated from the steel as a loose black powder, hence the necessity for the spacer on the bolt. Using rusty material includes a mandatory shaking and thats it. A vibrator will also help on the casting, leveling up from the prodding with sticks from the last video. Massage anything or a drill with hammer function on the table does the trick horribly loud

[@giuseppebonatici7169]

I would recommend to print the "concrete-related" parts with PETG. why? PLA degrades in contact with concrete. concrete is highly alkaline and attacks the PLA to generate lactate salts. It is worse when you try to reinforce concrete with PLA, but the same problem should arise: the concrete will not adhere to the PLA as the boundary layer of lactates (that generate initially, and grows over time) is powdery. there is quiet a bit of research, PETG (in the cheaper end, of course) is the best for reinforcing concrete (as does not react at all, and their properties are not crap like ABS/ASA) PLA is good for everything else that do not store energy for long periods of time (creeping problems). ABS/ASA is best for high temp apps but not exposed to UV (but if you are already spraying cancer particles and toxic fumes, you could just use PC if your machine can melt it)

that's an interesting point, though I reckon one solution would be to coat the inside of the ball with epoxy

[@ryanokeefe12]

Rust won't cause the concrete to crack over time. Not sure where that person/people got that information. The surface rust actually helps with the bond to the concrete and once the concrete has cured, the rusting process stops. Rusty reinforcement is installed into concrete slabs every single day. Concrete cancer is probably what they're assuming will happen, but concrete cancer will only start if a portion of the steel is exposed to water/oxygen.
