This is my first instructable.
I am just a hobbyist who interested making circuits and their pcb's in complete DIY manner.i saw lot of articles of home made PCBs.they were quite good except one step.making holes for mounting components.start from laser printing the PCB layout to mounting the components you can carry out in home except the drilling procedure.you shld have a drilling machine with small drill chuck,which is capable of holding 0.5-1.5 drills.
Then i had in my mind,why not DIY PCB Hand drilling machine.
My goal is to built one from junk which is capable of drilling small holes to mount components.
Remember this is not sort of professional drilling machine.with it u can just make holes small enough to mount electronic components over PCB.
Finishing of the drilled holes will depend up on the type of drill you used.(made)
Below is my PCB hand drill and my PCB making setup.
Step 1: Stuff needed
This is what u need to built a PCB Hand drilling machine.
1. 24v DC motor (takes from old dot matrix printer)
2. Nylon pulley (from printer only)
3. Mounting screws 3mm (these are used to mount mother board in CPU cabinet)
4. 3mm hardened screws (2-2.5 Inch in length)
5. 24V supply,some basic tools,Grinding machine with Rough and smooth wheels.
