I learned the hard way today that there's a right and a left outside
blade for my Freud SD208 stacked dado set.
After happily cutting nice box joints for quite a while I pulled out
my trusty dado blade today to make four desk drawers. I cut the first
set carefully and dry fit - a bit looser then usual, must be the MDO
plywood I'm using for the first time. Anyways, forged ahead and
whipped out the rest of the drawers and dry fit - well, these went to
the scrap pile.
Must be something wrong with my home-made box joint jig - nope. Maybe
something got jammed into the dado stack - nope. Then noticed I
didn't have the outside blades with the 'painted' sides on the outside
as usual - yep, that was it. The cut is slightly wider with the
I don't know if all stacked dadoes are like this but mine sure is.
Hope this note keeps someone from wasting some drawers like I did.
Hope my next project has some smaller drawers so I can use that scrap.
P.S. The 1/2" MDO plywood I got at Menard's is pretty nice stuff -
five plys, real stright, no voids that I've run into yet, and not too
pricey either. Poor man's baltic birch, I suppose.
