Two or three days ago, I decided to revive my "poor man's lathe", for which I made some small accessories, as detailed in the last step of that instructable, added today. I decided to make, within other things, a top as those I used in my childhood, in times of Río de la Plata Viceroyalty.
Step 1: Limitaciones (limitations)
Since my lathe is a bit limited in their abilities, and I'm not habituated to using it, it took more time accommodating the parts than doing the work. But next time, I know how I should build everything. The rotation axis must be tilted, so that using only the longitudinal movement can be made the conical body of the top. Obviously, each pass I pull up the grinder to the center of rotation.
Step 2: Ahora, a Jugar (now, to Play)
The metal pin on which the spinrotates was not perfectly centered, because I should have started out there and not on the body. I know it for next time. The defect does not invalidate the work, only makes the top to jump a little, rather than stay in one place as it should.
Step 3: Advertencia (warning)
Beware! If you don't know how to throw a spin, do not practice near people, or glass, or fragile things, because until you learn is likely to make some havoc.Then do not say "I did not know," I warned you.
