Easiest I've used is a sheet metal shear brake.
Harbor freight sell small ones (8" wide I think) in the $100-$200 area.

um..., Hi

is there anything cheaper like cutting it with a dremel and a cutoff disk?

I have used a band saw with no prob...

Russ Ferguson

A small band saw from HomeDepot with a fine tooth blade does a great job.

Hacksaw works just fine also.

When cutting with a saw of any sort, please avoid breathing the stuff.

a BIG OLD CUTTING BOARD. the kind teachers use to cut thru a big stack of paper.

Just don't cut your fingers off. Because the circuit board will most likely move on you.

BPM,

·· Have you actually tried this?· My guess would be the board would crack in an irregular pattern and/or shatter.· I remember a friend trying to use tin-snips and that's the result he got.

Dremel and cut-off disks works nice for me. Then I finish the edge and do the rest of the shaping with a grinder. Both of these are low impact - minimal vibration to the board. Just be careful and wear eye/mouth protection/filters

Ryan Clarke

I can second the band saw suggestion...with fine teeth on the saw blade it works just fine....don't forget mouth AND eye AND nose protection...

Just be sure to cut before you mount components *teasing*

We use a tile saw here at Parallax for our boards and it works great.

I use my tablesaw with a fine tooth carbide blade. For small pieces, I hold the board in place with the saw lowered. I raise the saw right though the board. This way I don't have to move the board in close proximity to the blade. In 30 years of sawing I have never been injured with a tablesaw in spit of the fact I remove the guard.

Although I haven't tried it myself, I've been told that a regular old office paper cutter works well.

I prefer the board shear we have at the office, but I've used the dremel, table saw, and scroll saw methods in the past. My favorite way is to get th eboards tabbed from the board house, but barring that, I have used my router table to score boards with a 45 degree conical bit. The major obstacle there is finding a way to do the second side scoring safely. I have a jig I use on mine.

This is not a sig. This is a duck. Quack.

Paul Baker

I have heard that a glass cutter can work, but requires some finishing, you score each side then snap the two apart. It leaves an unfinished edge which requires further sanding, but you should have a higher chance of a nice straight break, something much more difficult to obtain with a dremel doing the entire cutting. Of course this isn't the best method, but not everyone has access to a band saw or a board shear.
