Re: How to cut circuit boards?

Hi Stan,

You are absolutely correct that Bungard is not the way to go IMO. 
http://www.covenantgroup.com.ph/covenant/bungard1.html

I haven't tried Bungard but I have been forced to work with Kepro 
Shears ($565 when they were in business) and it was always tricky to 
use and everybody was always tense using that bloody finger eater.  
However, once I got the shears mentioned in msg 3510, the cuts look 
great. I cannot produce the scan because I am in the middle of a few 
projects but I tried cutting it several times, different sizes and 
concluded that it is simply an incredible tool. If you saw it and 
were not familiar with that tool you would probably never figure out 
its M.O. The price right now is so bizarre that it's laughable. 
Sorry, I couldn't produce images, but imagine having a perfect cut 
with a perfect tool, without dust and with much less risk to your 
fingers than by using Bungard.

Mike
