PCB Drilling?

I have heard that tugsten carbide pcb drill bits are too fragile and will break if used with a hand drill. I dont want to buy a drill press due to the cost (unless i can find a small and cheap one)... so will a 1/16 drill bit be ok for pcb holes for standard through hole components? because that is the smallest drill bit size i have that successfully works with my hand drill... any personal experience, knowledge or advice to help me? and thanks

Deep Hole drilling

This might sound stupid, but I've been wondering, is it possible to use a gun drill on a drill press? Does a drill press accept gun drills? If not, is it possible to modify the drill press so that it accepts gun drills? How? I've used normal drill bits to make "deep"(about 4 inches) holes in metal before, but it was very, very difficult to get it straight, and the metal became hot as heck after a while, sometimes the drill bit even got stuck in the metal and it was extremely difficult to get it out. Thanks

Drill battery Switch

Hello! i got a car horn with an motor, the motor is rated 12 Volts so i got a 12 volt drill battery since im not going to install it on a car. However, i got a problem... My plan is to mount 2 switches, a Keyswitch and a push buttom switch. so i bough that .. However it made me think if the small switches can take the Power of the drill batt. I have no idea how many AMps a drill batt got, and the key switch is rated 0,5A / 250 VAC and i the push/switch one is a standart like this https://elextra.dk/images/large/8011.jpg .. Now do you think i need a other switch or will i smelt them by pluggin the Drill batt on ?

Cordless drill power supply

I am using an EFUEL 30amp 18volt 540watt (model sk-200013)  power supply to power my Ridgid cordless tools. A dead battery was gutted and a power cord was soldered onto the circuit board inside the battery enclosure. My problem is that I encounter an OCP (overcurrent protection) error if I do not slowly power up my tools. I can live with this except for tools that are not variable speed (circular saw). If a Ridgid cordless tool demands full power at start up then the OCP error condition is triggered. My question is that I have heard that the installation of an external capacitor will eliminate the ripple effect and smooth out the power demand on the power supply so that any tool used at 100% demand at start up  will work without causing the OCP error condition. Is this correct? If so, can anyone tell me the type and value of the capacitor to use? Any help is appreciated. JEM213

Using a mounted drill to power axle mounted device

Hi, I have just constructed a chicken plucker as in the photo. As an initial attempt the device worked really well - except for the connection of the drill to the axle. This was not well aligned so it ate the threaded bar which was trying to pull itself out and not helped with the thread direction. Are there examples of how to better power such a device?  I would like to be able to re-use my drill, I suspect properly aligned would work better. I could also swap to a non threaded bar but would need suggestions on how to keep the plucker barrel in place. Cheers

24V Panasonic rotary hammer drill - battery and wires got hot (drill didn't) and drill stopped working. Answered

I have a 24V Panasonic rotary hammer drill, model EY6813. It came with two 3.0 amp-hr NiMh batteries, both of which had a problem with one of the contacts almost welding itself to the contact in the drill, and also in the charger. I stopped using those batteries. Now, using an external 7.0 amp-hr NiCd, it's worked fine until recently. The drill began to intermittently shut-off, then quit working altogether. I then noticed that the battery, the wire running to the drill, and the contacts in the drill were hot (battery was very warm, the wires & contacts were VERY hot). Any ideas about the problems with the NiMh or NiCd? Could it be the drill and not the batteries? The hot batteries/wires occurred after minimal runtime, so I don't think its a matter of overdrawing the battery, but I'm just not sure. The vent holes on the drill are not blocked.

Why the cordless drill motor not run?

Hi all, I have a problem with the motor of the cordless drill. I converted my cordless drill from Ni-Cd battery to Li-ion battery 12v6 using the protected PCB as this image: http://www.ultest.com/shop/image/cache/catalog/Power-Modules/HX-3S-A01-1-500x500.jpg. After connecting the 3 cells Li-ion battery to PCB, I measured the voltage at P+ and P- is 12v. So the connection between the battery and PCB is correct! Try to connect P+ and P- (from PCB) to the positive and negative terminals of the motor, then the PCB cut-off voltage at the output pin. The reason is the 2 terminals of the motor is connected (using the Digital Multimeter to check). How to resolve this problem with the motor working properly? Thanks. Sy Do

Need help with power supplies

I've been reading about electronics for a while and watching the Make podcast and I've finally started making my own projects. Anyway I have some cordless tools with 3 extra batteries but only one of them still takes a charge. So I thought it would be cool if I could put a power supply in one of my dead batteries so that I could plug it into the wall. I've been looking around my garage and thrift stores for a wall wart that would get the job done (the batteries are 19.2V Craftsman batteries I think they pull about 2000ma) but the closest I've been able to find is an old laptop power cord has a DC output of 19v and 3.9amps. So I'm not sure if that will work or if the extra amps will burn out my tools or something. Does anyone know if it would work? If not how can I dial down the amps?

Removing a teeny/tiny iPod/iPhone drilled screw

Hello, I have been doing some repair work on an iPod Touch 3G. One repair I'm having to perform is the power button which is totally unresponsive. This required removing some very soft tiny screws at the bottom of the device. Unfortunately, one didn't survive the screwdriver and quickly chewed up, which means I've had to drill it using a drill bit, which took a surprising amount of effort. The problem now I have is extracting the final stem which is still screwed in. The stem isn't flush with the metal but it's not far off, making it hard to grab using pliers. I'm looking for some suggestions how to remove it. I've read that cutting a thin screwdriver in half and gluing it using super glue is a way. Another way seems to buying an extraction set but the only one I can find in the area looks far too big (despite having a precision piece). Thoughts? All suggestions welcome.

First of all what the hell is that striker made of and second of all what the hell drill bit can get through it, I knew they were tough, I couldn't be assed cutting one with just a hacksaw blade so i did it with the drill as a lathe...
