I need help with adjustable leed out guide

I looked up plans, and hopefully found the correct ones.  It is just a comb.  Combs are diffi9cult, even in plywood.  The teeth require stable material, so the wood needs to be best quality.  

Pilot drilling then carefully sawing to the pilot may be a good choice.

I would consider plastic or aluminum if the plywood you can obtain is not stable enough.  A hardwood part glue stabilized may also work well.  

I also wonder about your tools, this cannot be made easily with a knife, the wood gets pushed too much as knives normally deflect the material as they cut.  A bench pin and coping or jewler saw, or a scroll saw are rather required.  If you have to use a knife then dragging the sharpened back of the point like a single tooth saw is the way to go.

Or coroplast like New222 suggested.

I like that! You could probably use a needle with carpet-thread.. and "sew" the ends of the coroplast-strip onto the wing. Maybe place a few drops of thin CA on the thread to lock it in place.. and/or keep the knots tight.
