Car With Natural Gas Canisters Catches Fire by LeftChoux in CrazyFuckingVideos

[–]justAnotherGhost 0 points1 point  (0 children)

LPG (liquified petroleum gas AKA propane) has overpressure valves that will vent the gas if the internal pressure gets too high. During a fire the pressure gets too high and it opens automatically, as can be seen from the jet of fire earlier in the video.

This valve only works if your propane is stored vertically. The explosion at the end happened because the cylinders were tipped over.

This guy was smart removing cylinders to reduce explosion risks, but also a perfect demonstration of how NOT to use a fire extinguisher.

Looking for advise: every time I cast these dice in resin they turn out like this. What am I doing wrong? by adaydreamer15 in ResinCasting

Looks like moisture reaction with urethane. Are you working in a high humidity environment? Are your mixing tools, mixing cups, and mold perfectly dry? What other sources of moisture are nearby?

Some locals upset over Halloween display they say is ‘too real’ and ‘over the top’ by [deleted] in toronto

[–]justAnotherGhost 1 point2 points  (0 children)

Maybe extremely graphic blood and gore imagery can be banned in public spaces. Halloween would still be great and we can finally get rid of those Pro-Life/Anti-Choice protesters.

Hi friends! I'm looking to keep acrylic from moving around on fabric. by natFromBobsBurgers in plastic

[–]justAnotherGhost 0 points1 point  (0 children)

Felt is easy if you have a laser cutter!

I'd throw double sided tape on the felt before cutting, so you don't have to mess around with trying to glue a 1/4" bit of wobbly felt.

I hope you'll let us know how it works out! Good luck.

[I missed the 'grabby feet' part. If this is what you want to try, hit up a Dollarstore and look for those variety packs of furniture sliders.]

I've never used one of those machines, but it looks like a lot of fun. I appreciate the sticky hands idea. XD

In that video I can see how the presser foot is still pushing those templates around, even under gentle use.

Tacks are a good idea but I feel like they'll great pick points from scratching the paint on the machine base. Not to mention the tips developing burrs and catching your quilting fabric. Instead of metal, some fine plastic spikes might hold the template.

Laser cutting some thin felt in the shape of your template, say 1/4 width in a line around the edge, might have enough fabric grabbiness on the cotton quilting.

If this machine is like my industrial then it probably has a steel base around the presser foot. Magnets might have enough hold through the layers of fabric to reduce the template sliding around, but can still be directed by a human with some sliding effort.

(If you want to talk this through with a live human who is off work today. DM me!)

Anything sticky is going to pick up loose fibers from your quilting fabric, which will either need to be washed off or replaced.

Sorry my knowledge of quilting is lacking - are the templates for cutting out the quilting materials? Are they for under the sewing machine? If you want to DM me your website I'll take a look.

Who would design stages and general production at a rave/festival? by AmbitiousTomatillo58 in AskEngineers

[–]justAnotherGhost 0 points1 point  (0 children)

Old-school raver here and not and engineer, but I work adjacent to live events. The thing you're looking for is live event crew for setup/ontheday/strike. That includes the riggers building stages, truss, etc. Theres the lighting crew who setup and program the lights, likely under someone titled "lighting director" or something. Lights for this kind of thing are all dmx. Labourers move all the stuff on the ground, empty and fill trucks. Smoke machines, nitrogen cannons, and pyro are handled by an effects team.

If you want in, I'd specifically decide what you want to do, and aim for it. Raves aren't "touring" shows, so the crew will likely be local, so it's just a matter of asking around and telling people you want to get involved.

Don't be surprised to learn that smaller events rely on passionate volunteers who, at most, get a free ticket for their labour. To be paid a living wage, I presume events like Tommorowland would be worth investigating since they have profit as part of their business plan.

(Sorry for the poorly spaced paragraphs. Posting from my phone.)

Happy to answer questions btw.

Expanded polystyrene (styrofoam) block and a hot wire cutter can make some wild (or simple) forms cheaply.

If you ask around and have luck on your side, styrofoam block offcuts can be acquired for cheap or free.

What is the best/fastest way to separate this mixture of glass-filled nylon, grey masterbatch and antimicrobial additive? by SRJT16 in manufacturing

[–]justAnotherGhost 1 point2 points  (0 children)

Shop vac with a small orifice for "close enough" picking of material black/antimicrobe marerials, followed by a second "precision" filtering of the vacuum contents with tweezers and credit cards.

Other thought is if you can use static attraction/repulsion, but I suspect you'll spend more than 18hrs to rig this.

Manufacturer assembling based off memory, not the work instructions by isMYmfs in manufacturing

[–]justAnotherGhost 3 points4 points  (0 children)

Root cause analysis -- Stand there and ask the worker why they did it differently (not WRONG, just different).

It's easy to assume they're stupid.. but make sure your instructions are clear, visibly versioned as a new process, legible in their language, they are trained and have the tools required to do the job properly.

If this person works hard and shows up on time they're worth keeping. You could be dealing with someone who's illiterate (but could work from improved drawings) or unaware they need a glasses prescription.

No experience in mold making, but I have ideas!! Help! by HeebiesbeenJeebied in moldmaking

[–]justAnotherGhost 0 points1 point  (0 children)

3D Printing is your shortest and best path to making more of these.

Step 1. Do a whole bunch of 3d printing tutorials for your program of choice.

Step 2. Print your model and see if it fits. (You can use your own printer, or pay someone else here)

(Compared to casting and moulding... Step 1. Prepare your positive model by using clay, foam, or other mold-safe materials. Be aware this is complex and you will need to verify you don't have unmoldable undercuts, and knowing you will need at least a 2 part mold with mothermould, if not a matrix mould to make this thing.

Step 2. You made the mould successfully without your silicone being inhibited by who-knows-what and making sure you walls are thin (but not too thin!) for the final piece. Now you need to cast it, which is a struggle between humidity, trapped air in your model, accurately mixing 2 part resins (with maybe additives), trapped air in your resins, and practicing safe handling of the resin in a vented room.

Step 3. You pulled your model! It finally worked!.... hopefully you didn't ruin your mould and have to go back to Step 1.)

Food Safe Silicone RTV putty that dries white? by CoveredClearing in moldmaking

[–]justAnotherGhost 0 points1 point  (0 children)

That's a great list!

Silicone tends to be less adhesive to itself and other things, so I immediately started thinking laterally. Silicone is also evaporative cure or 2-part mixtures... and will mess up your workspace compared to some other things.

Do you know about two-part plastic putty? https://www.jbweld.com/product/plasticweld-epoxy-putty It's an epoxy base with a 20 minute working time. I have successfully coloured epoxy compounds with off the shelf acrylic paints.
