I need help with adjustable leed out guide
Guys I am stuck on the guide for my ambush. I have made three attempts and failed to make it per the plans. Besides, I dont like the design. Do you have any pictures that may give me some ideas.

Re: 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.

Re: I need help with adjustable leed out guide
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.
Re: I need help with adjustable leed out guide
If this way is thought of, what I would do is teh following. Give it a quick sanding with a scotch-brite pad or equivalent, followed by a quick 'flashing' with a lighter/torch, etc. Then glue it to whatever using your favorite epoxy or CA glue. The above instructions are for the coroplast.. However, if the wing itself is painted, I would also give it a quick sanding using the Scotch-Brite pad also before gluing for the best adhesion. The wing however, would not need to be 'flashed'.
