We often take electricity for granted, so that we walk into the room during a power outage and still habitually flip the light switch. On the other hand, due to weak infrastructure or remote geographic location, there is no electricity supply in many places. To get common power tools to work in these areas requires some ingenuity, as seen in this construction, it converts a chain saw into a gas-driven grinder that can be used to cut steel or concrete. (Video, embedded below.)
All the parts required for the conversion are manufactured in the mechanical workshop of [Scratch Workshop]. First, a non-cutting chain is installed on it to drive the cutting wheel instead of cutting directly, so a new bar must be manufactured. After that, the construction showed how to connect the bearings and fix the entire assembly back to the air motor. Of course, there is also a customized protective cover for the grinding wheel and a protective shell for the chain to limit the danger of operating such equipment to a certain extent.
Although there are some safety considerations in this version, we still want to reiterate that all necessary safety equipment should be worn. That being said, this is not the first time we have seen a modified chain saw more useful than its default wood cutting configuration, like this one that turns a chain saw into a metal cutting saw.
A chainsaw, like an angle grinder, is a very good tool, and you have to chop it off to do other things completely.
I respect this person’s skills very much, but the battery-powered grinder is cheap, powerful, and has a lot of safety features, such as anti-rebound protection. I know that gasoline grinders are the same thing, but I guess they have their own set of safety features?
I hope to see at least some calculations at the beginning of the video about the speed of the chain saw and whether the disc is safe.
They make pneumatic sabotage saws, and you can buy different wheels for them. This idea is not new or original. DIY may be half and half. I’m not sure if they use different bearings and filters on the destruction saw. As someone who uses metal cutting blades in circular saws, before I tell you, the motors on them don’t like to suck in metal shavings more than sawdust.
The cutting disc shows 5100 RPM, both gears have 19 teeth, the chain saw seems to be Piła spalinowa Magnum MG-P-5800, the specification is MAKSYMALNE OBORTY: 11 000 +/-500/min… This may be a medium good The idea is to try full throttle.
I would say that there is a medium probability of danger. I have tested the grinder to verify the protection of the guard and can see that the built-in guard in this video is not strong enough if he blows up the disc at 11k RPM
I don’t know, when I had to cut some copper pipes as big as work for the chiller system, we just went to Lowes and bought a pipe cutter… it cost less than $20… it probably took a full 90 seconds to cut
I don’t like power tools life tips, they are meaningless, and they are always the same in the end, IE this thing is rotating shit, let’s add an accessory that needs to be rotated to work “HAXOR!!!!”
