Hi Doug,
You have a deal. Anything I come up with you can use on your web page, etc.. Thanks, Jeff On 12/29/2013 12:53 PM, Doug wrote:
Hi Jeff and Paul, It's been a few years since I assembled this concept guillotine design into a drawing, and I emphasis concept. It was to show a principle of slicing the fibres as the force of the blade was applied with as much rotation of the blade possible. How the dimensions are determined can be proven using a cardboard mock-up and leaves plenty of room for innovation relating to the features you mention. These are the things that I would explore with this concept: 1. The angle of the ground blade, and which direction the angle/s should face the stick to prevent shattering (unless you need this factor). 2. The angle of the blade support plates. 3. The blade diameter. 4. Addition of a bottom blade, possibly to facilitate cutting angles. 5. Blade can be mild steel with welded hard facing, like the Screw Auger Laimet chipper. ------------- As a project, nobody has reported back to me that they have tried to make one, and I have not the time myself to iron out any wrinkles. I will however discuss it today with a mate who might be interested in pottering around to keep his hands busy. Unlike building a gasifier, many on our forums will have plenty of ability to knock it into a working design as an interesting practical project. I suggest the floor is open to all so we can fatten out the potential details. Doug Williams, Fluidyne.
