50cc Chainsaw Build
I scored yet another couple of cheap chainsaws the other week and among them was this 50cc beast.
When I got it it looked like it had been sitting out in the rain for some time and everything was seized on it.
After a lot of WD-40 and gentle persuasion with the hammer everything moved freely and one fuel line later it started straight away.
I thought I'd better rebuild it as it's in need of a good cleanup.
As I'm pulling it apart I'm thinking that I don't REALLY need a chainsaw this big.
My little 36cc Jonsered (Turbo) does me just fine for whatever I need it for at work plus I have a Stihl I'm about to start fixing up as well.
This one is also a bit heavy to be swinging around, it has an 18" bar on it, and quite frankly, I'm a bit scared of it [
]
So, what shall we do with it then?
Why not build a car.
A big one.
We'll see what happens.
In the meantime here's some pics of the saw.
(Bet noone's ever heard of OLYMPYK Agristar before......)

RE: 50cc Chainsaw Build
Nice find. That looks like a good quality saw.
The only problem I could see with using such a big engine is with the steering....but you will probably figure something out
If you have any decent size hills nearby you might want to make a hillclimber. That would be sweet [>:]. I have been thinking about building something like that with one of my big saw engines too.

RE: 50cc Chainsaw Build
Yeah well I put a 50cc chainsaw on a Razor chopper and it pulled me no problem at all so I think it should be strong enough.
As for the steering, well.... we'll worry about that when we get there.
Triple 1/4 scale servos maybe?
Maybe when the time comes someone's cracked the wiper motor servo setup......
For size and wheels I was thinking something crazy like spoked pram wheels at the front and front ride-on lawnmower wheels at the rear.....
Wheelbase of about one metre and fully welded steel frame.
Maybe something along the lines of csisco's trophy truck setup.
Either way - it'll be big.

RE: 50cc Chainsaw Build
Pic # 4 from the top made me a bit scared. So you have the 36 turbo too? That is what started my build by the way. But now there is a 44 in it, almost as big as a moped engine! But physically not much bigger than the 36 in fact.
Exciting to see another big build from you, DVP!
Mudgy; lol at the chased greenies!

RE: 50cc Chainsaw Build
the 85cc McCulloch saw I have with a compression release (even with that you can only pop it over 3 times on a pull), now THAT is a big engine, have a couple bigger too...

Yeah I picked one up cheap.
Really cheap.
All that was missing on it was the muffler.
But I'm keeping that one as a saw.
Good little machine.

I think my biggest saw is an old homelite from the 50's, if I remember right that has a 95cc engine, 24" bar and no muffler... but the stihl chopsaw engine I have might be bigger.

RE: 50cc Chainsaw Build
Here's some more pics of the motor.
It should be pretty easy to mount it on a frame as it's basically a big box with right angle sides and plenty of holes to fix brackets to.
I won't be using the internal fuel tank though.
The clutch sits with the teeth on the outside which will make it a bit easier to mount a sprocket on it.
Crankcase still needs a good clean.
Reminds me of this thing:

RE: 50cc Chainsaw Build
Guys, be prepared for a lot of "How do I make this with my lathe"? posts.
Actually here's my first question already:
Scroll up to the post where there's a picture of the clutchbell and a sprocket.
Will I be able to put the bell in the chuck and chew the teeth down to fit inside the bore of the sprocket?

RE: 50cc Chainsaw Build
Yes, i guess so! Maybe you have to tight the chuck "inside" the bell if you know what i mean. Oh, did you remembered to order some cutting tools for the lathe?

RE: 50cc Chainsaw Build
yes you will be able to trim the clutch bell, you won't be able to tighten it by the bell very tight without warping it, so take light cuts, be better if you had a live center and stuck that on the outside, a dead center if you don't have a live center...
if you have any questions, let me know, and if you need any tips go to littlemachineshop.com and look around, that one is usually known as a harbor freight 7x10 or 7x12 but it's sold under several names...
