Introduction: It's Possible to Use the Angle Grinder As a Chainsaw

Carrying on our tradition of our video sequel for angle grinders, this fourth time we transformed our grinder into another useful machine, a chain saw. Our primary aim for this transformation was experimental while the usefulness of the particular machine came second in our priorities.

Step 1: Metallic Plate

We first did this experiment for multiple reasons such as to see if the angle grinder could really work as a chain saw, whether the angle grinder is burdened, if it gets warm and if it can be used as a last resort in case of an emergency. Therefore, our work starts making a metallic plate, on which the angle grinder is adapted and stabilized when necessary. On this metallic plate, we placed a metallic rail taken from an arboricultural factory as well as the chain and the gear of the particular machine. The chain that we placed on the metallic plate is revolved on a high speed without derailing its way supported by the gear that revolves the angle grinder at the particular time. This metallic rail has the potential to move towards and backwards as a result to enable us to set how tight or loose we want our chain to be.

Then, we made a protective cover around the chain close to the parts that we place our hands in order to reduce any danger. Thus, without any special difficulty the angle grinder 4 is a fact!!!!

Step 2: Testing

After completing it and testing it, we got amazed by its performance as an electrical chain saw. Although, we consider that this was a transformation of a high risk. Also, we must say that using a bigger angle grinder, the performance will be dramatically increased. However, the advantage of this transformation is that none of the components is modified as a result they can be easily returned unchanged to their primary position, where they were placed at the chainsaw.

Step 3: Result

To sum up, this particular transformation costs very little money and it can work in many different cases having great results. Additionally, it is much lighter than the common gasoline powered chainsaws, much less noisy with a small angle grinder and this is obvious when it is used for many hours as its temperature increases.

I must say that this is extremely stupid. I believe in personal responsability all the way but no one should ever EVER use a chainsaw without kickback protection.

This is a neat idea and is executed well. A great Instructible. The people complaining need to realize that safety is like craftsmanship: it's not the result of what tools you possess, it's the result of how you use them. An off-the-shelf angle grinder is already more than capable of causing injury or death, depending on who's using it. But if you fully understand and remain alert to the potential hazards involved, you can safely use just about any kind of tool. Conversely, if you're careless, inattentive, or unskilled and overconfident, even the simplest tools can be dangerous.

I hope that you have great liability insurance. Posting instructions like this will get you sued, especially if it's a kid that gets hurt or killed.

I think should be entered into the new Darwin Award category.

If anyone is even thinking this is useful in their life, go and buy on Amazon the Remington RM1425 Limb N Trim 8 Amp 14- Inch Electric Chainsaw.

It's much cheaper than a trip to the hospital.

You know all you people bit-- and complain about his hack. Although I do not see anyone of you putting something up now or lately. What is it you only had one idea and it was a chainsaw and he beat you to it? I think it was a good hack and my saw works great, although mine is on a much larger grinder and I used an oilier from an old chainsaw and the teeth also. Nice hack Make it Extreme

Why not simply arm the angle grinder with a circular saw designed for it?

Wikipedia chainsaw safety features... a good start to understand why this thing is a bad idea.

This thing is deadly or highly dangerous.

The user should highlight the dangers of operating something like this. Even with a good operator and proper use, this thing is still dangerous.

I enjoyed laughing at this... but this thing shouldn't be anything more than a comedy feature.

Having seen what a broken chain can do, back before they had the hand guard that locked the chain in event of a break, I wouldn't THINK about trying this hack!

what about oiling the bar and chain?

author
PedroB12 (author)Darth Bob2016-08-05

Gaffer tape an oil can to the grinder and make it a manual oiler :D It does need some lubrication so it is really only a proof of concept which has already been done on Youtube .

The horror possibilities of this are absolutely cringe-making.

A fine proof of concept, but definitely a hack NOT for the everyday, accident-prone DIYer - nor the non accident-prone amongst us.

The basic angle grinder concept (right angle gearbox) and body finds its way into woodcarving tools like Arbortec and into biscuit jointers.

Even when unmodified, angle grinders can bite back, as can wood carvers and biscuit jointers. There's a lot of torque at the spindle. The old spindle moulders were often described as the most dangerous tools in the workshop, but for my money there's not much to choose between any of them. As I found out recently, even a wrench on a stiff nut can cause torn muscles. You never stop learning, but don't end up in Accident and Emergency.

Ummm, I believe it's called 'The Lancelot', and they are stationary on a 4 or 4.5 inch disk setup. Very dangerous, grinders point this out in the manuals. This looks way too dangerous. Now if you wanted to weld little paddles or ducks on the teeth it would be cool, but no oil, chain larger than a tool...just looks like an accident waiting for this guy. CARELESSNESS IS A BAD EXCUSE FOR BLEEDING, and I see no care here.

Have fun you kids, and be back soon. dindin is almost done.

Wooow thats one of the coolest homemade tool ive ever seen. Amazing!!!

treenail (author)rbclima2016-08-04

A paddle switch angle grinder is the ONLY choice!!! Not slide switches incase/when the saw kicks back.

A squirt bottle of oil would be sufficient to lube the chain. I;ve done this when the oiler on a chainsaw wasn't working. Inconvenient but it works.

Using safety or anti-kickback chain and a short bar...12" or less...would be the best.

gm280 (author)2016-08-04

OIL, where is the OIL? I can see chains dissntegrating easily. There is no oil to keep the chain both lubed and cool.

There is a reason people are not suppose to be making their own explosives, bombs, guns, etc, at home. Add to the list, chainsaws!

Despite all the comments about safety, which I'm sure you were aware of befor making this, as a proof of concept it is great, and could easily be used to make a safe logging or milling machine !

Kickback is the danger when using a chainsaw and all modern chainsaws have a kickback or chain brake. I used to live in rural VT and knew one logger (a young one) who deactivated the chain brake because he was "so strong that he could control the saw in the event of kickback." Well, in front of his pregnant wife, while cutting a log lengthwise, the saw kicked back, flipped up and cut through his shoulder/collar bone. He could not hold it back! He did recover and was lucky that he didn't perform brain surgery upon himself, and it was "only" his shoulder.

I know this set-up has the saw sorta sideways, so it doesn't go directly back to the user in case of kickback...but, I, having lots of experiences with chainsaws, would not use an angle grinder as a chainsaw, except under a real emergency situation.

In fact, don't use a pre-chain brake chainsaw. It ain't worth it. This is one safety feature that really is not just a Nanny-State edict.

great mod.

but if you need an electric chainsaw i can HIGHLY recommend the Homelite.

i have several gas ones, but this is the one i use near the house.

Agree with all comments. The real value is in the ability to adapt something in an emergency, and keep your mind active. How many of us who learned the same basic concepts early in life can still recollect them when needed.without practice? We forget that sometimes tinkering is to exercise the mind and learn what works and what won't. Too often people refuse to engage without a competitive goal in mind.

Just because you can build something dangerous, doesn't mean you have to - and if you do, not necessarily use it. Problem is that other people may try and do the same from inspiration, not thinking about the consequences.
If you have a workshop with tools like that I'm sure you should already have some sense of preservation.
Very nicely built though.

If I may say it in the nicest possible way, you are a Lunatic, Sir! You need an auto-kickback device on a chainsaw of that size - and I sincerely hope you never find out why the hard way! Meanwhile just stick around a calm assistant with their cellphone poised to call an ambulance.

Billrose (author)2016-08-04

The idea is good, changing the angle grinder into a chain saw. But all chainsaws are dangerous and this version is quite lethal. Plus the lack of oil on the chain and the ability to tension the loose chain. BUT! the idea of tools being re-used and the skill of tool making is impressive. So I give you 10 out of 10 for invention. (but minus several million on safety..!) Please keep going, its a great idea to change and modify tools.

This is an interesting project and as it is purely a proof of concept I won't grumble about the safety issues the open drive sprocket and lack of chain brake would raise in use.

In practice I think you'll find that the limiting factor with this design is the lack of a lubrication system for the chain bar (the flat guide around which the chain runs). Without lube (and some petrol(gas) saws can use more lube than fuel) the bar will heat up very quickly causing distortion which in turn can cause the chain to jam or jump out of the guide.

author

That is a really interesting point... I never though about that.

author

Chain lube is very thick and sticky. If you warmed it a little and used an oil can or veterinary syringe to inject it manually onto the chain and guide before each use you should be able to use the saw for short periods. Do let us know if you take this any further and solve the lubrication issue - hacks like this are great to see!
