Sandblasting Gun

thingiverse

Weekend project I think the concept of this DIY sandblaster is familiar to most: a simple compressed air gun is used to shoot sand at an object to clean it. The normal approach is to simply drill a hole in the neck of a PET bottle, and then put it over the nozzle of the gun in whose tube you have previously made a hole. Works, no question. However, it's incredibly annoying when the sand-filled bottle constantly tilts from one side of the pistol to the other. Because you have to peel off the bottle again and again to refill it, the hole quickly leaks out and the condition gets worse. My approach is therefore firstly to separate the bottle from the gun and secondly to secure it against twisting. These DG-10 pistols have a hexagon on the outlet, which is wonderfully suitable for fixing. If you use simple PET bottles, you also have a widely used PCO1881 thread with which you can work. You can download the result of my weekend project here and use it at your own risk. There are two versions that differ in the position of the six-edge. The part actually clamps wonderfully on the outlet nozzle, nevertheless I recommend gluing it additionally. I have also illustrated the development of the part, maybe someone is interested in it. Note! The hole I cut into the pipe is definitely too big. The sand runs out far too quickly. I would make the hole at most half the size and then work towards the right size - if necessary. I added a picture of an old hammer. For the bright and clean area, about 3 seconds of the beam have been sufficient. Warning! Please always keep in mind that this is a printed part through which you shoot around 8 bar ... everyone should be careful. In addition, the whole thing makes quite a sourness, so it should be used only outdoors. It's essential that you take the necessary protective measures, such as goggles and respiratory protection. I would be happy about a post about your MAKE and if you like what I provide here, you could think about a little tip... unfortunately, too few do so.
