So does the genuine Veroboard cutter. It's just a stub drill mounted
in a blue plastic handle, and its only advantage is that it's easier to
hold. There's quite a good picture at

You can probably get one from Farnell in NZ. The part number from the
(UK, Farnell-In-One) catalogue is 329-538. It looks similar but not
identical in my catalogue to the one in the CPC catalogue, which is
interesting because Farnell and CPC are part of the same group and
share stock. Same price, though, UKP 6.60 (and the NZ price is
NZ$25.94).

Ah... I was under the impression that the cutting edge had a
substantially different angle fro a drill (like describing a 180
degree arc between the cutting surfaces rather than, say, 150
degrees).
I guess this picture...

... really shows the divot one gets from the real tool.
I might just have to just use the drill press for this task (taking
advantage of the stop to keep from drilling _though_ the resin board
;-)
The tool looks handy for more than a few cuts, though. I wouldn't
want to try just holding a bit bare-handed - lots of hand cramps and
slips probably.

Oy! The NZ price is a lot more than a blank vero board... and so is
the UK price! (for boards in NZ, not the US).
Thanks for the website tip... nice pix.

My tip:
- using a sharp knife, cut two cuts in the trace
- use the soldering iron to heat and remove the small fraction of copper
between the two cuts
Advantage #1: you don't need to buy anything
Advantage #2: it hardly damages the ressin
Advantage #3: you can even remove the connection between two pads
Advantage #4: You can make arbitrarly large areas blank; could be
usefull for isolation areas
Believe me, this works. Even on epoxy, but just as well on pertinax.
