Friction drive with chainsaw

FatManChan · #1 07-08-2009, 11:09 PM

I've decided to not use a chain drive as it requires more skill than I have. I'm now going with a friction drive. I have an old poulan 33cc chainsaw. The clutch is one where the sprocket is mounted on the inside so I'm going to use the smooth part of the clutch to spin my back tire. How would I design the pivoting shelf that friction drives use. The one that the motor pushes down on

Using the actual clutch as the drive wont actually give you any solid traction. the drive roller needs to have some sort of rough surface to it. The simplest is a bike peg.
And about mounting it, you need to give us some sort of picture.

One thing is that cent clutch will get hot and burn through your rubber, second of all the outer size on the clutch housing is to big (I think) to give you the right ratio, and last but not least you might have to add more weight to the clutch in order to even get that cent to engage with a humans weight on it.

Expecially if you are indeed what your name implies

Lol. I am a bit husky. But weight aside, could I use that liquid weld stuff to put some textured rubber on the clutch? I've seen a video on youtube where people used just the clutch and it seemed to work fine.

I'd get pictures but I have no camera

It really depends on the clutch, some Chainsaws are strong enough you can use it the way it is, but I doubt a 33cc would catch right as it would probably just die if or when the cent engaged. The clutch just has a lot of variables. If in doubt, try it out! Just don't hurt yourself in the process

Well I've lost all hope in myself at this point. Just spent 30 minutes yanking the pull cord only to find out I forgot to add gas. Anyways, I'll just try that first. If worse comes to worse I just have to move a few things around and weld a bike peg onto there somehow

I personally am a rebel and if someone says it won't work I'll find a way too make it. Just trying to give ya a heads up to what your up against.

I've known from the start that this wouldn't be easy, but hey, it's a summer project
