How to make a low-voltage mini cutting machine from a cardan crosspiece

For those who do not have a workshop and have to work right in the apartment, an important parameter when choosing electrical equipment is its noise level. Finding such a tool is not so easy, but you can do a lot of things you need with your own hands, for example, a cutting machine.

Main materials:

  • motor 12 - 24 V, 200 W, 6000 rpm - http://ali.pub/4kgmr3
  • Power Supply;
  • profile pipe 100x50 mm;
  • profile pipe 20x20 mm;
  • cardan joint;
  • bearings 2 pcs .;
  • sheet steel 3 mm;
  • corner 25x25 mm;
  • pulleys 2 pcs.;
  • drive belt.

Mini machine manufacturing process

For the base of the machine, you need to cut off 220 mm of a profile pipe 100x50 mm.

It is necessary to fix the cardan joint on it. It can be welded, but it is better to screw it to be able to adjust the cutting angle. For this, a hole is drilled in the pipe with an offset to the side, and a nut with a sleeve is turned. Using the latter, the hinge can be bolted.

Then the vice jaws are cut from the corner. One of them is screwed to the base in front of the slots. The second should be sliding. To do this, a strip is screwed to it with 2 screws so that they can walk along the slots. Also, from the square, it is required to make an emphasis with a threaded thread, when rotating in which the pins can be unclenched or squeezed a vice.

Further details are collected. Bearings with a bushing between them are inserted into the housing on a swivel bracket. Through them it is necessary to wind a bolt with a pulley. Then the engine is screwed on, also with a pulley, and the belt is pulled. You will need to make a belt guard from a bent channel or loose along a profile pipe.
