Gear for chainsaw clutch.

[Luka]

I have an old husqvarna 380CD chainsaw I am considering for a friction drive build.

The clutch drum and chain drive is on the 'inside'.

Does anyone have any idea how to put a bike chain gear on the inside, instead of the chainsaw chain drive ?

You could try sticking the clutch drum on a lathe and removing the teeth of the gear thats on it, which would leave a nice place to weld on a drive sprocket.

I dont know about that chainsaw because it is pretty big, but most of the ones I have toyed with (30-50cc) have tiny metal shoe clutches that slip very easily.

Might be best off removing the stock clutch, bolting on a drive sprocket straight to the crank, then running that to a jackshaft with a Maxtorque clutch on the other side.

Or you could fab a gravity clutch. This is basically an engine mount that allows you to raise and lower the chainsaw motor onto the tire.
