I show how to cut a perfect positioned and straight threaded hole easy, quick and precise. Thread tapping on the milling machine or drill press is fast and accurate using the right tools.

It would be very nice if we could discuss there everything about Stirling engines, 3D printing and more, thank you very much Baptiste.
Only perfectly straight thread cutting allows for easy manufacturing and precise assembly.
I'll show you a quick and precise method for making perfectly positioned and straight threaded holes using a milling machine or a drill press.
I need to cut 20 threads and drill a few holes in the iron core of my new linear generator.
I want to do this quickly and accurately.
The vise must be precisely aligned; a tolerance of 2 3 hundredths of a millimeter over a length of 150 mm is acceptable to me.
Depending on the size of the workpiece, you touch-off the corner of the vise s fixed jaw or a reference edge and set the axes to zero at that point.
When clamping the workpiece, make sure that it lies exactly straight against the measured surfaces.
This allows the drill positions to be reached quickly and accurately when working with multiple workpieces in different orientations.
We will now centre, drill and countersink at this position.
Taps with straight flutes are used for through holes, while helical flutes ensure that chips are carried upward out of the hole when drilling blind holes.
At the end of the shaft, they usually have either a point or a small hole.
To ensure precise alignment, we now need exactly the opposite shape, which is easiest to make from an old tap.
This piece is then clamped into the drill chuck.
Insert the tap with the tap wrench precisely into the center and gently push it into the hole using the quill.
The thread can now be easily cut by applying a steady amount of pressure.
Even with this pure iron, which is somewhat difficult to work with, there are absolutely no problems.
Of course, it doesn't matter whether you use a CNC milling machine as i do or a conventional one.
With a drill press, you have to mark and center the workpiece the traditional way, but after that, everything works just the same.
My new linear generator fits together perfectly, and I hope it will perform well with my thermoacoustic Stirling engine.
Do you use a different method for threading, or do you have any other suggestions?
Please write it in the comments!
