Sled rats greasy lil chainsaw thread

[sledrat]

OK here i go again gonna try this again folkz,,

OK i WAS a lil bored yesterday and going through my shed ,,
Noticed a Broken lil Mastercraft 35 cc chainsaw hiding out in the corner,,
It had a busted bar bolt and to fix it would mean a whole new housing ,,SO nawww it had no value to me for one as a antique saw wise or chainsaw wise,,
BUT BUT The motor did work well!!
ANyways thought i might as well mounted it to a old three wheel bike some how??? ,,,.,,

In a hour or so with a few pieces of scrap angle iron from a old bed frame and few good hose clamps and a lil saw ,
,heres what i came up with,., a Friction drive Chainsaw bike,.,

I know its not pretty but it works and all but is not pretty... Oh well

Now to set up the old metal lathe and to figure out how knurl the clutch drum surface for more traction ,, HA!










STAY TUNED FOR THE TEST DRIVE

Knurling the clutch drum is going to eat up the tire. Fix up an adjustable mount with a mechanical tensioner. and figure out a throttle cable arrangment up to the handlebars.

You need a matching motor on the other side.

that's gotta work pretty decent. petal with the bike crank to get'er going then use the chainsaw to keep her going. I bet that clutch drum would roast that tire under some load though. avoid hills

cut an inner tube and glue it to the clutch drum, rubber on rubber, solex mo-peds use that..it works

Ya that seems logical

I know that when you slightly gas it catches not bad but if you rev t out watch out it will eat the tire..
but if you feather the throttle it works you have to feel the clutch grab,,,and let it grab,,
the way its mounted its not that hard to steer and use the throttle where the saw is mounted....,, I guess i could alter the carb cover and run a weed eater throttle cable to the carb,, But really i dont think its that important,,Just wanted to see if it was possible..
BUT ya when you get it up and going
it does go pretty decent really for the amount of time i put into it..
sure beats paying 250 bucks for a kit lol./.
I think infact the clutch drum should be even smaller for better torque..its a lil to high geared.. I wonder what type of glue and what type of rubber could one put on the drum?
heres a lil test vid

 

[2strokenut]

i chain drove one years ago it worked but the clutch did not hold up that well but i do like the way you have done it fixing the rubber to the clutch drum is a cool idea i wonder about fixing a small rubber wheel to the clutch drum

Looks to have good "sideways balance"

By the way you ride a girls bike:hmm3grin2orange:

A pair of ported 6 CI saws woud be about right.

All right, where's the test drive video?


This, I GOTTA see!

 

[Stephen C.]

the clutch diameter is way to large, you need to pull it off and install something a lot smaller or use it to drive a secondary sprocket/gear reduction of 3 or 4 to 1
