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

Old Sewing machine
PCB drill motor http://www.banggood.com/12V-Small-PCB-Drill-Press-Drilling-With-1mm-Drill-p-929516.html?rmmds=myorder
LED strip
Old pens
Pen caps
Washers, Screws
Hot glue
Wire
6MM MDF
Binding wire

Step 2: Disassemble Sewing Machine

Disassemble sewing machine and remove all the internal parts except switches and DC jack.
Cut the front portion as shown in picture.

Step 3: Base Plate for Motor

Cut 6MM MDF and hot glue it to the sewing machine as shown.

Step 4: Sliding Mechanism

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.

Step 6: Base Plate

Glue a plastic sheet.

Step 7: Motor Fixing

Drill holes to the MDF and tie motor with zip tie.
Apply hot glue.

Step 8: Motor Fitting

Screw the motor to pen's as mentioned earlier.
Apply hot glue.

Step 9: Making Handle

Drill a hole to one end of the pen so that we can fix the pen to base plate.
Fix the pen to MDF so that when we press the handle, motor should move downwards.
Fix a plastic piece at the center as shown in picture.
