For a long time, I thought that the boring head at the NHF was not needed due to the low rigidity and low boring height. But in the end it became clear that its use could not be avoided, only at that moment the price for a head and a set of cutters became virtually unrealistic. Then, nevertheless, I decided to get confused and make it myself, using the same NGF 110 and a TV-7M lathe.
The head size is slightly smaller than the F1 sold in China, namely the diameter is 48mm. After manufacturing, I noticed that I did not make a third hole for mounting the cutter in a horizontal position, but this is not critical. The marking of the limb will be carried out after the restoration of the HV-6 turntable using this head - this is such a cycle of equipment on the machine.
Also in the video, the thread diameter of the main screw was not correctly spoken, there is M10 in 1mm increments.
