So when one is the designer, what looks good on paper is not always good in life. SO we made the insertable tabs for the struts. After setting the landing gear mounts in place they were blocking the holes for the tab bolts, so back to the drawing board. Did a little redesign and updated the plans.
For the holes you want to drill thru the ply plate, tab and the landing gear block for the bolts. For the ply plate enlarge the holes so the bolt heads can go thru the ply plate only.
