Let's solve some problems: Yes, this assumes that you already have or can use a compressor. So, if you do this and know what you are doing, why not build a cheap sandblasting device? This is what [adamf135] did after seeing someone doing this on YouTube. He seriously doubts whether this is feasible, but the results are impressive.

This only requires an empty 20 oz bottle, a cheap air gun/nozzle and an adapter. The hardest part of this hack seems to be cutting a groove in the nozzle for the spray material, rather than cutting it off completely. [Adam] A 1/2-inch section was cut from his body, but such a large opening did exhaust the blasting material. He suggests to be smaller. After cutting off the sealing ring, he inserted the nozzle through a 3/16-inch hole, drilled in the strongest part of the bottle, and sealed it with hot glue. Watch it rust and paint with broken glass after cracking.

If you do this kind of public sandblasting, be sure to wear at least a mask. If you don't want to spray fine particles throughout the workshop, you can build a wet medium sandblasting cabinet, or use a lower technology and build a drill-driven parts drum.

Yes, wear a mask. Silicosis is real.

Do not use sand, use sandblasting media such as alumina or glass/ceramic

In the long run, this is not important. Inorganic (or continuously supplied organic) particles that stay in the lungs are a good way to get cancer or other serious respiratory diseases.

Walnut shell is very suitable for removing general "silt" without damaging the surface, but it is not effective when it is severely corroded or thick paint layer.

One area where it has been widely used is the cleaning of airport runway lights.

I heard that dry ice works well.

When you think about setting/cleaning, is sandblasting actually faster than ordinary sanding? If you don't mass produce, this seems troublesome.

And in the open air, there was dust everywhere in that shop.

Try "ordinary sanding" of the inner cable or anything else with a complex and tiny structure.

Normally, it is done in a booth with a pair of thick rubber gloves inside, turned inside. I forgot what those were called. In fact, it works. My friend has a fool who cleans spark plugs. You only need to stuff the business end into this small rubber seal, and it will circulate sand inside without causing confusion.

Of course, when you are doing something very big... well... doing it manually is worse. It is always rounded corners and details. Sandblasting is very equal to the worn surface.

It is called the glove box...

It's really fast, for example, you can't match the surface finish of glass beads on aluminum. The tumbler is also very suitable for finishing, but it is slow and difficult to find.

Silicosis is still a problem in underdeveloped countries. These countries have not replaced the use of silica sand with milder materials such as garnet.

Use glass beads. OSHA recommended. Amorphous = no silicosis.

Won’t the garnet grit get stuck where you can’t see the broken machinery?

Even without silicosis, breathing dust is not healthy.

After about fifteen years of exposure, this is true. You must have a job that does this on a regular basis to really attract attention, and I certainly hope you have safety equipment by then.

There have been cases of silicosis in 18-year-old children in India http://news.trust.org//item/20160509120656-r8djg/

A mask is not enough. The most serious particles produced by sandblasting are smaller than those that can be filtered by ordinary particle masks. Everything I've read says that you should use an air supply system (air is pumped from the clean area into the mask).

That being said, this applies to avoiding silicosis in the actual sand. The glass sand used in the video is obviously suitable for use with masks and filters. There are also things like carbon dioxide and soda spray, which are completely safe by themselves (although the sprayed thing may not be, so wear a mask anyway).

Yes. This is a good picture showing what helps fight silica particles http://www.nj.gov/health/workplacehealthandsafety/documents/silicosis/respirators.pdf Although not everyone can use this pdf The recommended method in) is a more realistic description. Obviously, the types of respirators range from FFP1 to FFP3. Since FFP2, you have only begun to protect yourself from sand, but use FFP3 (full face mask or with a clear description of this type). A half mask with a good filter) is much better. We will now buy a better respirator, not aware of silicosis-unfortunately we only used the basic FFP1 respirator to do a lot of plaster grinding and a lot of dust.

This is not true at all. Carbon filters can filter gas molecules-they can definitely filter dust. The key is to make sure your mask is well sealed, and many people don't even check it.

I'm sure this works, but another thing that works is the sandblasting machine they sell at Harbour Freight for $20.

If I did this just to save $14, I would have to surrender to the State Labor Commission for violating the minimum wage law.

Why is it so negative? Many people cannot use Harbour Freight or similar stores. Others may not have 16 dollars. People who read HAD may prefer to build by themselves rather than buy.

Considering that the author used Harbour Freight’s air gun nozzle, I think he can indeed use it.

Yes, but the dozens/hundreds of people who may copy the project may not be able to use Harbour Freight or its $20 sandblasting machine. Maybe he recorded it for those people. who knows.

However, Carl S does have a good point. One of the things of sandblasting, soda blasting, glass bead blasting, etc. is that it uses a lot of air. The volume it uses is much larger than that required to run most pneumatic tools. Therefore, you need a compressor that can deliver large capacity. Anyone who cannot afford a cheap sandblasting machine will not have a powerful compressor.

The spare tire of their car is filled up at the gas station?

It will run for a few minutes at most, and the pressure will continue to decrease as you use it. Not practical. I have seen spray guns operated in this way, but their air volume requirements are much lower.

Well, the ceramic nozzle that the sandblaster should use is much more durable than the (improved) metal nozzle used here. I don't know how good it is, so this may not be a problem, but it is worth considering.

The design of the gun is cool, but I can't do sandblasting without a sandblasting cabinet...

Easier to recycle media...

One of the cabinets I saw had an "upturned range hood" style layout with a turntable in the middle. The used media only needs to be slid from the inclined side of the "base" into the container below.

Of course. Or stand against the wind. Or do not exceed a thousand hours. Or use glass beads.

Neither can solve the problem.

Your lungs are very sensitive-protect them.

In Arizona (or arid regions in general), there will be more windy days. One must judge the risk/reward and the total risk in the real world. You can take all precautions, hide inside, and filter everything. When you die of urinary tract septic shock caused by pulling out the catheter multiple times at the age of 100, you will have the lungs of a 90-year-old man.

But if I stay at home... I will be poisoned by radon.

Good tutorial IMHO, but what are the specifications of your air compressor? Am I missing this somehow? Roughly speaking, how much do you want to spend?

So now people are pointing out that this may be dangerous, is it to make fun of it?

I guess you are welding without goggles, handling high-voltage equipment with electricity and placing flammable substances around the furnace?

Now. Just don't cry for every damn little thing, live your own life. Unless buses or bullets let you come first, cancer will kill us all. A handful of sand is an acceptable risk.

People just don't want to be told what to do. This is our nature. Otherwise, the Darwin Prize would not exist. It would be great if our behavior was more like the product of millions of years of evolution than a moment of genetic agitation. But there is only so much that one person can do.

Yes. The gestures and virtues attracted by these stories are very distracting. All commenters tried to surpass each other in describing all the dangers, occupying so much space.

What actually happened is important. How many users who occasionally sandblast suffer from silicosis due to sandblasting? How much comes from the sandbox? How many are sand cast? How much does it take to go to the beach or the desert? Is it the main cause of death in Libya and Saudi Arabia?

How many HaD readers do you think do not understand flammable materials or wear goggles? Or eat a dishwasher detergent pack?

Well, this is a great hacker. I will show this to people in the store on Monday!
