Ideas for Repurposing a 2 stroke Chainsaw Motor
« on: December 30, 2015, 10:12:36 AM »
What are some good homestead ideas for repurposing an old chainsaw motor?

I have an old 34cc McCulloch chainsaw. The engine runs great, but the bar oiler is broken and shop is unable to get parts anymore. They said it's not worth fixing and I should just throw it away. Since the engine still runs great, I was thinking of repurposing it into something else like a scooter, mini generator, or wood lathe.

I am leaning towards a mini generator. I could just bolt it onto a piece of wood next to a car alternator and run a belt between the two. Let me know any other ideas you may have.

Maybe a rope winch?

In a past life I remember seeing an alternator generator made with one, but considering the number one complaint about most generators is the noise they make, errrm, I might have second thoughts. Like the rope winch idea a lot.

Maybe I could mount it on a trailer hitch stem. That way I could easily take it on or off the back of the truck.

Have an option to have a chain hook on it. I used a Lewis Winch with the forest service for a number of years and being able to hook a winch to a stump and pull logs and rocks for trail building was an amazing force multiplier. Some of the most robust trails I've ever built came out of having that tool available; despite having one of the smallest crews I'd ever worked with.

That's quite a contraption. And yes, Lewis winches are great, but not cheap. I love the idea of a rope winch because you can dally it and have any length rope you want. A winch will always have a fixed length. If you were really slick you could actually tie lengths of rope together and use them, although you can get static ropes up to 600' if you wanted a dedicated rope for it.

I saw that rope winch in a catalog and thought it was a clever idea.  I don't know what I'd do with it, but I want one. Now that I've seen a Lewis winch, I think I want one of them, too.

That engine probably has around 1.5hp at 9000ish rpm....which won't amount to much as a generator. 1hp = 768 watts in an ideal world. It could work as a winch, but it will require substantial gear reduction as is the case with the Lewis winch and those capstan style winches. It will also need a load holding brake and a clutching mechanism of some sort.

I just checked and the complete oiler is still available. Looked like all the parts were available individually as well. http://www.ereplacementparts.com/oil-pump-p-615270.html Most likely the shop knew it would cost more in parts/labor to fix than it was worth. You should be able to fix it yourself easily though. Looks like it comes out as a complete unit with only a couple of screws holding it in. I may have the husky service manual for it...would have to look. Might also be that the oiler unit itself isn't bad, but the line is plugged or the drive gear on the crank is stripped.

Lots of fun things to do, not a lot of useful things. 

The rope winches ROCK, but need a pretty stout saw to really move them.  If you want to selectively log in thick timber, they can get logs out of places you can't imagine. 

The one thing I have wanted more than anything else is an engine powered drill/auger for planting bare root trees.  Supposedly easy to convert a weedeater but not sure how to do it with a chainsaw.

I used one of these as a kid when dad decided to plant a bunch of bare root pines. http://www.benmeadows.com/ben-meadows-tree-planting-bars_36811379/

I'm not gonna lie, that scooter in the second pics looks very cool. I'm way too old but I would have loved one of those as a kid. Nah, actually I'd still give it a go now.

That would be cool, but it would probably jeopardize my chances of survival.

The generator/battery charger is probably most useful for short run time of chainsaw motor IF auxiliary cooling is provided.

I saw these videos last night and remembered this thread. https://youtu.be/IbVFH_vg2fw https://youtu.be/3qSAtPDWEjE

He claims he gets 30 amps of output from it. At 12 volts, that's 360 watts. At 14 volts, it would be 420 watts. Not a lot of power, but enough to charge a battery.

Been meaning to post this same question for awhile!

I don't have much use for a winch, but I do like the wranglerstar video!
I'm too rural to justify a bike conversion.

Maybe some sort of self propelled cart for moving materials around the property??
Problem will be setting it up such that I can engage and disengage the drive mechanism without having to shut off the whole engine....

Thoughts?

Centrifugal clutch ,just like chain saws and minibikes and many other things use.

While I can't see a 40-50cc motor running a very large auger, I would think it easier to convert a chainsaw than a weedeater. Both use centrifugal clutches, so there's no difference there. Both also use diaphragm "all position" carburetors, so there isn't any difference there either. The chainsaw does have mounting studs though, which are built in attachment point. It is entirely possible to buy a small engine powered drill. Stihl and Echo, among others make them. I'm also pretty sure that Stihl offers a number of attachments which are designed for their chainsaws.

I have a chainsaw winch. It's got a 30CC chainsaw engine on it. It's rated for 1800 pounds of pull. Pulling more weight doesn't require a larger engine, it requires knowing how to rig the pull. I can guarantee the little machine would pull 1000 times that amount of weight with the right rigging.
