Does anybody in the USA know where I can buy a guillotine cutter like the one shown in this video (it's about halfway through at 7:35), for cutting copperclad boards?

video link???????

That looks very much like the one that I use based on the short time I could see it.

I use a "Roberts Quik-Cut Vinyl Tile Cutter Model No # 30002"  that I bought off ebay.  Do a search and you will find all kinds of prices and knockoffs.
I got mine for less than $4 but the shipping was like $15 so make sure of what your looking at.

I use a brake I purchased at Harbor Freight for about $30.   Just score the copper and snap. Safer than a guillotine and many times safer than a table saw.

Keith,
That make sense as 150 degrees is about the glass transition temperature of regular FR4.
That was most likely to make clean cuts versus zillions of tiny glass shards when shearing.

Just my $0.02,

Does a brake prevent cracks as my diamond tip saw blade does and is safe while using the proper push sticks and feather boards as I am always looking for new ways to do any job.

Thank you for the info. I will stay with my way as I don't have that type money

For many years I used a carbide tile cutting scribe to score/snap PCBs.
But with thinner PCBs they bend and distort. So a shear might be better.
But they do NOT work on FR1 boards which are more rigid and more flat.

I recently switched to this 4" desktop saw for more precision and faster
'production' type work as I am starting a kit series.

The diamond blade is awesome and the product captures the dust by using
it in the same box it came in - cut down to access the table.

PCB distortion and dimensional precision is critical when trying to
build cavity filters etc.

I don't to spend $30 to score 'n' snap copper-clad.   All I need is a small piece of plywood, a utility knife, a straightedge, and a counter-top.   I already have all of these things - so zero $.

Guillotine cutter is a misnomer because this machine looks and functions
nothing like the labor-saving device of the revolution in France.    I looked
up "brake", and the sixth-most-common definition  at dictionary.com is
"Also called press brake. a machine for bending sheet metal to a desired shape."

So it's not a brake.

The 17th definition of shear as a noun there was
"a machine for cutting rigid material, as metal in sheet or plate form, by moving the edge of a blade through it."

So I guess it's a shear.   Now that I know what I'm looking for, that might speed things up.   :) No, am not looking for a machine made of crap just because it is cheap.   That's a one-use tool.    I want to use the tool for years,  at least 10,000 cycles, preferably 20,000.       When I was much younger, I made the mistake of buying a portable handheld jig saw.   It  broke on my first job.    I learned my lesson that day - don't buy cheap tools if you can only afford to buy one of each.   And don't buy power tools with the Craftsman brand name.

So I guess the shear I am looking for  basically does the same action as a heavy-duty version of a paper cutter, that slices copper-clad rather than paper, eh?

I know exactly what I am using.  It is a brake.

And other than just snapping PCBs.  I use it for making project boxes.

I found this PCB board cutter for a little less,
http://www.grizzly.com/products/12-Combination-3-in-1-Sheet-Metal-Machine/T21320
But weighs 114 #, so freight makes up a bunch of the price difference.
Not sure--is 22 gauge steel thick enough to cut PCB's?   I don't know the 22 gauge.    Plus it bends as well as shears.   And slip rolls, whatever that means.     But I wouldn't buy it without a personal recommendation.

I have one since quite a number of years. To cut a few PCB'sit is expensive but I never tried as I cut them with a little table saw.!

Here I can cut and bend aluminum sheets up to 1.5mm thickness. The cutting quality is good. The bending at 90 deg angle is tedious to following the marking on the sheet and in fact does not bend completely at 90 degrees on a 1.5mm thickness, a bit better on 1mm thickness.

The handles are not the best for using the device as I have to knock on them with the palm of my hands because the lever is not long enough for the strength needed. I had to turn the two in aluminum.

All in all not a bad device if one is getting used to it and nice for relatively small pieces.

imo, if you spend the money buy a brake, not a multifunction machine.

If you can afford the expense, and do some metal bending work too, invest in a finger brake.

Hi,

A small ceramic tile saw will work too. They also use small diamond blades and water to keep the dust down. Spendy but useful for other things too. http://www.homedepot.com/p/QEP-3-4-HP-Wet-Tile-Saw-with-7-in-Diamond-Blade-22650Q/202615612
