Do you have a router? Do a search on this site for router sled! Cheap wood, and cheap plane and bad grain direction, and no experience will give you fits! The plane can be fixed to work, the grain direction [if already glued up] kinda screws you. Experience with a plane takes time, quite often, a lot of time! A router sled is your best answer here!
^^^^ No blade comes sharp enough to meet my standards. The blade is gonna need sharpening out of the box. You want your blade to barely protrude through the mouth of the plane. Usually when I set the cutting depth I back the blade out to a point that it isn't protruding at all, Then I use a small scrap of wood and turn the adjuster until the blade just barely passes through, and I run the wood on each side to make sure I'm getting even sized shavings on each side to make sure that the blade isn't skewed, if I need to adjust the blade, I tap the side with a tiny small brass hammer until I get even shavings on each side. Then I back the blade up so I am not cutting. I run my plane over the work piece and turn about 1/8 of a turn as I slowing push it across the surface, I do this until it starts cutting. I can make a video of this later when I get home if this helps you.
