My latest tool and project which I made in a day from a local wind blown Laburnum this cutting gauge.
Measuring 4” by 3” by 1-3/16” with a 3/4” stick also from the same timber.
The stick is secured by a disc and side plate setup from the rear of the block by a transverse 10.00mm nickel silver solid rod drilled to take a 6.00 thread which is intersected by an ebony knob which has the 6.00mm bolt cut to length and also threaded and glued into the timber.
Inside the main body hole is a recess to take a side plate and behind that an fitted from the inner surface of the hole is a 5.00mm thick pressure disc which fits snug in the side hole.
The knob has a small shoulder spigot at the junction of the thread and where it enters the block through the 10.00 hole drilled into the end of the block.
In the front lower face I fitted four blind 10.00mm by 4.00mm blind nickel siver discs for asthetics and wear limiting.
The cutter is held in place by drilling a 10.00mm hole in the end of the stick to take a 25.00 by a 10.00 mm rod insert which is drill through its main body and a 6.00mm hole through the stick…. The insert is also drilled and threaded throughout its length to take a 6.00mm Alen grub screw. The blade is held in place via a small nickel packer and the grub which pulls the mech against the stick body when tight.
The blade is made from a piece of HSS industrial metal hacksaw blade and sharpened only on one side with the flat side outermost when in the stick.
