Homebrew PCBs

I know I've said it before -- but then again, I don't think anyone has actually listened! Before investing in a $300 tablesaw or a shear of doubtful capacity, consider buying a metal cutting bandsaw (NOT A WOODWORKING BANDSAW!!!) such as this one:

Yes, it is going to cost more than a cheap shear or tile saw, but with a 20% off coupon (fairly common from this retailer), the price is not too bad -- and you get something that does a surprisingly good job on metal.

For PCB's, I use a 24 pitch metal cutting blade (NOT A WOODWORKING BLADE!!!) -- it cuts fast, clean, and accurately, and the blade does not get dull. I've used the same blade back and forth between PCB's and cutting metal for quite a long time.
