In this article, the author of the YouTube channel "Be Creative" will tell you how to improve ordinary lerka.
If you try to cut a thread of a sufficiently large length using a lehr, then you get this result - the thread will turn out with an offset relative to the center.
The author suggests a little refinement of the design of this tool.
Materials
- steel bar
- Long M2 bolts, nuts
- Bolt diameter lerki
- Solidol
- Aluminum bar.
Instruments, used by the author.

Manufacturing process.
The master removes the die from the holder, marks and drills a pair of holes with a diameter of 2 mm near the handles.
Then, in an aluminum block, he makes a hole for the bolt, sets the die in place, presses the workpiece with a bolt.
Now drill holes for mounting bolts in an aluminum block.
Unscrews the bolt and prepares two stands for the block.
Then it fastens the stands and the block to the holder.
Tightens the block to the die with a bolt, tightens the nuts.
Alignment is observed, the bolt can be removed.
Here is an improvement for the holder came from the author.
Now you can safely cut the thread of any length on a steel bar.
This is how threaded blanks look, cut with and without fixtures.
Simple optimization is suitable for almost any holder.
Thanks to the author for an interesting improvement for Lerka!
