Looks a bit excessive IMO...I use a cheap little hacksaw from my local hardware store.

I make 3-5 boards a week... either for customers or for myself...trying to score them with a utility knife or cut them with a dremel, it either takes too long or doesn't cut perfect... between teir $40 drill press and $50 mini table saw I am two steps closer to having nice professional results in the optimum amount of time.. the powder coating setup is next :)

If you're going to spend money, and if you make a fair few boards, a guillotine is the quickest and best option.  It's also the safest - no dust!

I like the guillotine approach too...I picked up a benchtop 6" metal shear at a House of Tools or maybe Princess Auto *edit: for 60 bucks* and it's great for cutting pcbs....couldn't be easier really, and no dust.

Gotta say though, that mini table saw looks pretty neat!

Glass fibre can irritate the lungs.  As far as I know it stays there.  It's a real concern.  I know this from my time of 'working' with fibreglass. 

It's thought that resins like epoxy might be carcinogenic.  Time will tell. 

I am concerned, read some stuff on fibreglass and you might be too.

I cut them with ruler and sharp blade, it's enough to cut about 1/4 of board thickness and it will snap straight when broken...

Hey,
 :icon_idea:
the last times ive used a little, and easy to make tool......get yourself a router, make a small table to clamp to your bench(a piece of wood, drill a hole in it and fix your Router beneath.)Get a set of bits with ballbearings on the shaft, make yourself a template of a piece of wood and then you can tape the PCBs on it and drive it (carefull) along the bit....its even possible to make complex cutted PCBs.
This takes little time to build and make the templates for your PCBs, but once youre finished you can cut many PCBs to absolutely accuracy in very little time.
I also use this setup to Cut Custom Pickguards in my shop.Works well!
If needed i can make a drawing for you....please let me know.
Good Luck,

Matthias

That thing looks like it would work like a champ, too!  And if someone owes you money.... start with the pinky

Whoa, a shear and a brake in one... that looks sweet! I think some of the Luddites in this thread don't get that many of us do this sort of a thing as an excuse to buy cool new tools  ;)

airborne fiberglass particles are actually quite similar to asbestos.  I use tin snips to cut my boards.

I couldn't find the one I really wanted to recommend. I have the 12" version. It has a shear, brake, and also slip rolls for rolling sheet metal into tubes. Yeah, right, like I make a lot of sheet metal tubes... 8-)

But the shear is GREAT!

A couple of jobs ago..... we bought a Central Machinery brake/shear/roller from Harbor Freight and the guide for the shear was not perpendicular to the shear blade! We had to install our own block so we could make straight cuts. During the assembly process there were bolt holes that weren't tapped, bolts that were not threaded, etc. Had similar experiences with drill presses and other Central Machinery tools. If you are able to 'rework' them, they can be worth the risk, but I wouldn't expect them to be perfect out of the box.
