People powered woody garden waste shredder Answered

Would someone please make an instructable for a hand or bike powered 'shredder' or 'chipper'  that doesn't involve welding.  Bahi did a great one, but it requires welding, and we don't have that available.

The woody stuff that needs making into much smaller pieces are: orach stems, collard and kale stems, summer squash vines, perpetual spinach roots, tomato stems and Florence fennel stalks (they get to be about eight feet tall each year).

You need something with a lot of torque. Bikes may not do it. Though here is a bike mulcher:

Now, pedaling a bike generator to charge a battery and then running a small electric motor might be better. Slap up a home made solar panel to help out.

These guys made a hand powered shredder, the TMC-1:

Requires welding I think.

I'm going to make a hammermill myself. But it needs welding and about a 3-5 horsepower electric motor. Some examples:

You can buy plans for this mystery hammermill machine $15:

For the cheap/insane people you can convert your lawnmower:

Fantastic! Thank you!! This is exactly what I was hoping for.
The bike mulcher is small enough that it would be practical. Attaching it to a 5 or 10 speed bike (cheap at Goodwill) might solve the torque problem.

You needn't use electricity.
A heavy flywheel will buffer so that you can pedal at a steady speed.

Prob. not. It will just make it harder to pedal I bet.

The guys doing bike generators are on it. Turning a generator with a bike lets you pedal at a steady rate of speed. Steady is what you want. Let the generated electricity do the work for you.

The little bike mulcher is a proper application, if you have only a little mulching to do. Try it first and see. Maybe it's all you need.

Pedaling at a steady speed would be much more comfortable. Thanks!
Am I missing something on the pedal mulcher? I didn't see any plans to build one or means to buy one ready made.

Yeah, I didn't see plans there. Goofy. These people "invent" things and never document what they display.

The TMC-1 I linked above has plans available. They are $30?
It's hand operated and meant for developing countries. So, it should be simple to build.

TMC-1 is probably the way to go. Thanks!!

Just find a way to bolt the parts that are welded together.

Thanks - it may come to that.
I really liked his use of a drill bit to break things. I use an old meat grinder to 'chop' zucchini (for bread)... a giant one of those would be nice - geared so a bike would have enough power. I have very little in the way of metal working skills.
