Guillotine

[Farrell]

Thanks for sharing John. Your chopper looks very interesting. Could you please expand - provide more detail - on the blade-holder hinges?

"The blade slides in two upright supports in walnut, braced across the back with the same walnut. These are provided with sailcloth hinges that screw into the base and can be raised or lowered to bring the fulcrum exactly level with the top surface of the cutting bed, which may be of various suitable materials such as wood, polyurethane etc."

Sailcloth hinges - as in what is commonly referred to as a luff slider or mainsail hank that go on the luff edge of a sailboat mainsail - the things that slide into a recessed groove in the aft side of the mast to attack the mainsail to the mast? Or are they something else?

How do they screw into the base? How do they raise and lower?

Thanks. Look like a real slick setup.
