Introduction: DIY PCB Mini Drill Press

Picture of DIY PCB Mini Drill Press

I had an old chinese sewing machine which is broken. I thought to make pcb mini drill press with it. I also placed LED's so as to use it in darkness also. It works with 12v DC. It can drill PCB as well as wood. It is very cheap and made with scrap material except motor.

Step 1: Parts Needed

  • LED strip
  • Old pens
  • Pen caps
  • Washers, Screws
  • Hot glue
  • Wire
  • 6MM MDF
  • Binding wire

Step 2: Disassemble Sewing Machine

  • Cut the caps on one side so that pen can slide easily.
  • Attach pen caps to the motor base plate with hot glue.

Step 5: Spring

  • Wind binding wire across a bold pen and make 2 springs.
  • Screw washers to one end of the pens and insert spring as shown in pictures.
  • Insert the pens to caps and check for free sliding.
  • Trim the pens to desired length.

This is an excellent reuse of other, expired tools. One can also get suitable motors from old printers too, thus bringing the cost down to near zero.

I plan on making one of these tool types soon but not for P.C. board drilling, but for pilot hole drilling, by using the smaller bit first to make a hole, a much larger final size bit will want to follow the first hole's path, thus increasing location accuracy- we now have another practical use for this design. ☺

I also tried with old printer motor ( epson), but the torque is not sufficient.

Thank you
