What to give a friend for a birthday? Each year the same ....
Pen, ballpoint pen. Good gift. Only here "Parker" is expensive, and if "BIC" to give is offended can be to him. And if i do it myself ? Under this project in the market I bought stainless steel rods, dies and taps with a small step and began to sharpen. I do not know which brand I got caught, but it was very poorly processed by cutting. If turning work still somehow, with a grief in half, at low speed with oil .... That drilling and threading turned into hellish entertainment. The instrument overheated instantly. I saw for the first time that after 2, 3 revolutions (by hands) the tap was heated so that it began to "boil" in water. I had to twist, cool the turn again again .... well, that the threads are not long. I burned two drills. But it is very beautiful shining. In the photo it is not visible, but I made the cap to the handle already from the usual steel, I passivated surface of orthophosphoric acid, it became gray, and not shiny. The cap has a collet for the replacement blade from the scalpel. The blade itself can hide inside the clamp.
