If you have been in woodworking for a while, you have probably seen where people use Playing Cards, to elevate the blade above the workpiece and then trim it down from there ... I don't keep playing cards in my workshop! instead, I wood veneers, they are perfect for the job, and yet another use for veneers. If you don't have any veneers, you should pick yourself up a small amount, they are available in many places.
