Homebrew PCBs

Hi,

After switching to niponcio's method of using label backing paper for
the TT, one major source of pain has gone away.

Now for another painful area - cutting boards.

I tried a jigsaw mounted upside down under a table - worked great for a
few cuts, till the teeth wore out - I gave it up because I knew the cost
of blades would quickly start to add up.

Then, a hardware store salesman recommended I build a mitre box, and cut
the board along-ways with a hacksaw. This works well - gets a very clean
precise cut, but long (15cm/6inch) cuts take 5 minutes of hard sawing
and gives me sore arms.

I considered a band saw but those things cost more than I'm ready to pay
at this time.

Can anyone offer any better ideas for fast precise cutting of boards
using cheap equipment?

Cheers
David
