  1. Hi Jim,

    Balsa is easier to bend, that is true, but it does not hold a nice round bend like the harder wood does. I just planked a ship with balsa for the first layer and found this out. I had to fill in several area where the wood took uneven bends.

    Hi, Vince, balsa shouldn't be bent, it badly bends and thus easily breaks. Inserts should be cut out from blocks or thick boards of balsa, then they very well hold a form.

  2. The electromotor

     

    Asynchronous three-phase general purpose of type the AИР power of 0,55 KW on 915 turns in a minute. It is connected to a network 220 in by means of working and starting capacitors and the magnetic starter, provides thus shaft power about 350 W. The given electromotor is chosen first of all because of a corrected speed and desire to use the direct drive. The Polish colleagues on the basis of long application of similar grinding machines experimentally installed that speed of twirl of a drum of 900 rpm in diameter about 50 mm is optimum wood for polishing (in particular, pears).
