Creating a Bicycle-Powered Woodcutter for Logs: Suggestions Needed

[anonymoussome]

I and few of my pals are making a project.

A circular blade woodcutter saw powered by bicycle pedalling for cost effective design for rural people where electricity is a problem...
We plan to cut Logs with it...and their cross section can be random...


Using a big circular blade.

Now how much large diameter blade is available and can be handled easily with manual paddling from an average man?

Please elaborate your suggestion.

What are your thoughts and calculations so far? Is this a school project?

I'd suggest that you start off by finding out how much power it takes to cut wood in a reasonable time (what horsepower rating do small chainsaws have?), and compare that to what a good bicyclist can put out for a few minutes at a time.

Although, I guess we can cut logs reasonably well by hand, so it shouldn't be too much different to do it with a bicycle drive...
