!!!!!!!!If I needed 20 boards I think I'd seriously consider looking at a commercial offering.!!!!!!!!!!

I'm putting on a little clinic on etching boards for our model railroad group. Although I have been aware of having to put on this clinic for two months, I dilly dalied around until last night when I am scheduled to do this clinic on this coming wednesday night...

Further to this, I am making up a little parts bag, and each person will etch his own board.....(I have pre-drilled the holes) then each one puts the parts together solders them in place, and hopefully after a couple of evenings working as a group, each member will go home with a "working" model of a dual flashing light.

Pray for me for Wednesday night, that all goes well.. This is the first clinic I have done on this subject.

Harvey, you are correct - the PCB section that is cut off does not do well at all, unless it's pretty large - couple of inches maybe?

Most all my boards are at least 1" to 3" in width, and that tends to cut off pretty good, but cutting a thin slice will just curl.

If I had to do 15 or 20 boards I think I might opt for a table saw myself - being sure to use a very fine tooth carbide blade.

In the PCB cutoff thread last week there was a really nice looking tiny table saw using diamond blade that looked like it'd do the trick.... If I needed 20 boards I think I'd seriously consider looking at a commercial offering.
