Haywire's Hobbies | Assembly / Pinning

1> Score the area you want to drill with your hobby knife. A small poke in the plastic/metal made with the tip of the blade will help keep the bit from 'walking' as you use it. 2> Don't drill your holes bigger than your pins. They work better if the hole is just big enough for the pin to fit in. I usually cut large paperclips for use as pins. That way, I can use a slightly larger bit, which is easier for me to get tightned in place in the collet. 3> Keep an eye on how deep you drill. You don't want to drill a hole all the way through something. Stick the bit in the hole and slide your finger as far up as you can. That will give you a good idea of how deep you are. 4> When drilling for pinning, check 2, 3 or even 4 times before you make the second hole to make sure everything lines up like you want. It is easy to make a hole once, it is harder to make it several times and have to fill in the unused holes.

one of the better ways I think to match up drill holes.. drill the one hole.. then stick the pin in... once you have the pin in.. on the other half put some poster tack on it.. then press the halves together. you will have an impression in the poster tack to drill your hole in then.. drill the hole :)

Another way to do it, if you don't mind filling small gaps afterward, is to first stick the parts together and only then drill a hole in from the outside, so that it goes all the way through the first part and then on into the second. Then put in a pin (glued in place, of course), and fill in the hole with epoxy putty.
