DIY Pcb Hand Drilling Machine

hello all,
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.

What are you using as a power supply?

[coder512]

I wonder if I get the drill which a Dentist uses to drill a tooth like this one lolzz

[arupbsk]

I'll also build a such drill.
But is there any wat to attach our normal titanium drillbits into the motor?

You can go further! See:

It works really well.
By the way, I had no trouble with your English. For a first instructable you have done remarkably well. Let's have more!

[beehard44]

sorry if i double post but, can i use a needle for this or is it too brittle?

[beehard44]

is it just me or do your drill bits dont have any cutting edge?

[tony54]

Any holes drilled in a PC board should be perfectly vertical (or as close as you can get). When you hold them by hand (I don't recommend it) you can never get it perfect but it might be good enough. Another problem is very small carbide drill bits for PC boards break easily if bent. I recommend a drill press at its fastest speed. Commercial drilling machines run between 40,000 - 100,000 RPM. I Dremel might get you 20,000 to 30,000, which does a good job IF held very still. Their Dremel vice is a better solution but more expensive.

is that a jdm programmer?

[Mr. Smart Kid]

cool but , throw out the iron the is insulated with abestos

[PyroMonger]

you would be wrong anyway. an iron wouldn't be coated with such a dangerous material. Have some common sense.

[PyroMonger]

did you mean to say the power cable is insulated with asbestos?

[beehard44]

the coil inside is coated with asbestos

[Mr. Smart Kid]

ABESTOS

[Derin]

spell correctly that is asbestos not abestos

[piper1234]

hey wassamara wita writn' "U" ma man? dis addy is kewl ; ) xD haha

For your first instructable... Not bad. I would have liked to see more detail in the steps of construction. Especially the grinding of your bits. Your spellchecker is working okay, but somehow accepted 'u' as a word. It isn't. It's a letter. Also, 'about' has three vowels, not one; There is a 'space' and a capital letter after a 'period'; And, finally, what exactly does "voilah" mean?

[lemonie]

Anyone interested in "voilah" may find this of some use:

[zorif]

yes i do accept.My english is not so good.and it is further spoiled by my SMS language about making drill bits,i will try to get a video.

[LasVegas]

No problem... Surprisingly, your grammer is excellent. Just remember, it's 'you', not 'u'.

[cpotoso]

Cool comments, but note that it is "grammar" not "grammer" :)

[LasVegas]

You're right... You caught my typo, smart-ass.

[Mr. Smart Kid]

vages your funny

[homebowyerboy]

It's vegas not veges. I agree nice instructable but work on the grammar a little. If I'm understanding you correctly english is your second language so if that is the case then I'll give you that. Nice effort and an excellent first instructable.

[microman171]

That is so AWSOME!!!!!!!! I hate having to use my pin vice to drill my holes (My dremel wont hold the bits and New Zealand sux so I cnt buy smaller collets) If I can get around to it then this it awsome. Now I need a bench grinder.........

[jtobako]

there is a drill chuck for the dremel/ect tools.
