Strange subject, you may think, but trying to enlarge small holes in plastikard can be a little tricky.

The method I use is to rotate a round-section needle file in the hole until I reach the desired diameter. Round needle files are usually tapered so the farther you go, the bigger the hole.

Now, the important part: only rotate the needle file anti-clockwise. If you do it clockwise it will screw itself into the piece and possibly split it, rather than just enlarging the hole.

Also, working from both side of the piece when you can will keep the hole more even; i.e. less 'tapered' as it goes through.

Same method applies to card too Perry.

That's handy to know, Bob. I didn't realise card modellers used files. :shock:

I use them quite a lot on shellacked card. The thing you have to watch for is 'furring' of the card surface, hence the shellac.
