Easy Torch Guide Makes Cutting Perfect Circles In Metal
“My prototype can cut out any size circle up to 4 in. in diameter. You can use it to cut out any size washer needed or cut a perfect hole in a piece of metal.”
At 83 years of age, Fedele isn’t planning to manufacture the device. He hopes to license or sell the rights as he did with an earlier patented device (Vol. 39, No. 1).
His torch guide is a ring within a ring. The outside ring is attached to a 1/8-in. thick steel plate for easy clamping in place. The inside ring has an adjustable inner arm with a cup for the torch head and 4 handle arms that extend outward.
“Adjust the cup arm to the desired diameter, insert the torch and rotate the ring with the handles,” says Fedele.
While his prototype has a maximum cut of 4 in., Fedele notes it could easily be scaled up. The larger the ring diameter, the more versatility it offers.
“You could have one that cut out a 24-in. circle and yet still use it to cut out a 2-in. circle just by adjusting the cup arm,” notes Fedele.
