Abstract
A tubular apparatus having a first end configured to slip over the screw of a log clamp used in a portable sawmill, and a second end configured with a plurality of serrated teeth. When the log clamp screw is extended it will engage a pin inside the tubular body and force the serrated teeth of the apparatus against a workpiece. The apparatus does not spin, rotate, or drill the workpiece when it is pushed against the workpiece by the log clamp screw.
Claims6
An apparatus for securing a log with a screw-type log clamp in a portable sawmill, the apparatus comprising:
- a tubular body having a first end and a second end;
- an opening between the first end and the second end of the tubular body;
- the opening defined by a wall in the tubular body;
- a plurality of teeth at the second end of the tubular body;
- and
- a pin spanning the opening in the tubular body and secured by the wall;
- wherein the first end of the tubular body is configured to slip over a log clamp screw in a log clamp of a portable sawmill;
- and
- wherein the log clamp screw engages the pin and extends the tubular body when the log clamp screw is extended.
An apparatus for securing a log with a screw-type log clamp in a portable sawmill, the apparatus comprising:
- a tubular body having a first end and a second end, the tubular body having a first inner diameter at the first end and a second inner diameter at the second end, wherein the second inner diameter is less than first inner diameter;
- an opening between the first end and the second end of the tubular body;
- the opening defined by a wall in the tubular body;
- a plurality of serrated teeth at the second end of the tubular body;
- and
- a pin spanning the opening in the tubular body and secured by the wall;
- the wall having a smooth inside surface between the first end of the tubular body and the pin;
- wherein the first end of the tubular body is configured to slip over a log clamp screw in a log clamp of a portable sawmill, wherein the log clamp screw engages the pin and extends the tubular body when the log clamp screw is extended;
- wherein the plurality of serrated teeth are configured to engage a workpiece when the log clamp screw is rotated;
- and
- wherein the apparatus is configured not to rotate when the log clamp screw is rotated after the plurality of serrated teeth engage the workpiece.
