Homebrew PCBs

I thought I'd just post this tip I found out a while ago when I was in the
workshop cutting out some boards and tuning some plane blades...

After rough cutting a circuit board to size, you can use a hand plane (e.g.
http://fingerlakesguitarrepair.com/media/tuning%20a%209%2012%20stanley%20block%20plane/1.0%20stanley%20nine%20and%20a%20half%20block%20plane%20tune%20up.jpg)
to neaten the edges, turns out FR4 is even nicer to plane than wood...
who'd have known!?

I'm not sure how hard it's on the blade, but a couple of swipes resulted in
a glassy finish. I used a number 4 as it was what I had at hand at the
time, but a smaller block plane like the one above would be easier to use,
or perhaps a little bull nose plane (though they're more expensive than
block planes which can be had for a couple of pounds at a car boot sale).

Anyone else got any unexpectedly effective ways of either cutting or
tidying up boards?
