I have the good fortune to own and use a Porter Cable 556
biscuit jointer. I would like to use FF biscuits and have
noticed that PC makes a 2" 4-tooth blade with a 7/8"
arbor for the newer model 557 jointer. Has anyone used
the 2" blade on their 556 jointer? I hate to spend
$50 on a blade that won't work.
