If you drill a pilot hole before you put your screws you can unscrew and re-screw safely, maybe you will just need to add a toothpick to the hole to give it a little extra grip when you re-screw
Cut a strip 12" or 24" inches wide measured floor to top of the desk that is what I called “wide” you can use very light plywood ¼ of an inch and add screws every 6 inches to compensate for the lightness of the plywood, if you use thicker plywood ½ an inch you just need to add screws at the corners and it will get your structure very sturdy. If you trace a diagonal line between the corners of your strip you will see that you are really adding diagonal bracing which is the only way to prevent the wobbling. Geometrically a rectangle can always be made into a diamond if you push opposite corners, with a triangle it is impossible, thus the diagonal bracing, I hope this make sense. It is also important to brace one side of your desk to the other. The “L” shape is also sturdier than 2 independent desks (someone else also pointed this out) if there is a way to add drawings to this comments I can send you some, just let me know how
The easiest way to prevent your desk from wobbling without adding to much weight and having to over tighten the nuts and bolts is to add a strip of thin plywood to the back of the desk 12" wide will work or 24" if you want to make it sturdier, it is a much lighter alternative and efficient than adding diagonal braces
No public wish lists :(
