motor cycle mill?

**Twinnie** · 1st June 2009, 04:41 PM

G'day all

I was just thinking why hasn't any one used a motor bike frame and swing arm to make a static mill? if you replace the shock with a hydraulic ram or some sort of adjuster and sick a Lucas mill blade where the wheel was...

I think the rpm's are about right and bingo, whether it's mounted on a sliding carriage or the log moves under it i'm not sure but am I missing something huge here? it could even have a brake...

whats more a 5 or 6 speed saw mill with a clutch, brake and 60 odd horsepower, even shaft drive if it's an bmw to keep the dust out of the driveline.

just thinking out loud

spinning the blade is only part of it.

could work, after all the yanks made a v8 chainsaw

i have given it some thought for a few years on and off, but for a logosol style chainsaw mill.
to use a bike like a lucas will not be easy because you can only cut in one plane , it would be a tad complicated to make the blade swing 90degrees for the other plane.

interesting idea where do you put the helmet??

I remember when I was a boy, my Dad and a few of his mates talking about an old guy (older than them) who lived up in the hills behind my hometown, he bought a brand new Harley davidson motorbike, set it up as a saw.

I never saw it, but they reckon it was pretty good back then.

hang on instead of having the bike standing upright you have it mounted at 45 degree angle to the left like you are going round a left hand bend , make your cut then flip it via a lever to make a 45 degree right hand bend and i believe you have taken out a wedge that is 90 degrees , or a 90 degree V notch on top of the log

so the idea has legs but as as texx pointed out the angle swapping is the hard part unless the bike in question was a sport bike with a dry sum and fuel injection... or the bike swing arm tensioned a bandsaw...

Similar applications have been done. IIRC, with a Model T Ford (or such) mounted on blocks, and a drive belt wrapped around one of the wheel rims, to power remote machinery. At a centre distance of about 5 or 6 times the rim diameter, the belt can make a 90-degree twist, if needed by the remote machinery. This was all before OS&H, of course, but safeguards shouldn't be too difficult to devise. At a slow enough "belt" speed, almost anything could be used for a drive belt - even a rope with knots.

You did not read this.

Cheers,
Joe
