Diagonal leg bracing for folding worktable
I am putting together a folding worktable based on a concept such as
this one: https://ibb.co/MgWrWrd One key structural difference (the other being the leg bearing  I am using 3/4" IMC) is that I won't be using the bottom shelf, so I will need a method to brace the legs from both hyperextending and folding inwards during use. The dimensions of my table are 76" x 32", and it will sit 36" high. The method I would *like* to use is a diagonal brace (aluminum angle, 1.5" x 1.5" x 0.125") on each leg, extending from a point on the leg to a point attached to the bottom of the table using 5/16" bolts. Here is my question: how short of a brace can I reasonably expect to get away with? It would be convenient if the brace were able to disconnect at one point and fold up with the table. In this case, the brace would need to be about 20 inches long and attach to each leg at a point about 14 inches from the bottom of the table. Considering the size of the table, the length of the legs, and it's use as a utility worktable in the garage, does this length of diagonal (and it's attachment point on the leg being 14" from the bottom of the table) seem reasonable or woefully undersized? Thanks for any perspective you can offer on this. Jon

The diagonal brace is folds in the middle. and attaches to the leg about half way to the distance to the floor. https://www.bjs.com/product/lifetime...00000000471184 On most tables I have seen of this type the brace overlaps the pivot point (like an "X") and a ring slip over the joint preventing it from collapsing. With the slant of the brace the ring automatically slide into position as the table is opened. These folding tables are quite common and you can probably see one to inspect at your local Church, store, or club house. While your table will be quite sturdy, it will also be quite heavy with about 35' of 2X4 plus the fastening. The one handle handle may not be sufficient to lift it. With our plastic table of about the same dimensions, it is quite difficult and cumbersome to move folded table.

The image you supplied shows a bench with not only a bottom shelf, but also stretchers between the legs to support the shelf, as well as stretchers on the floor. Are you planning on eliminating both the shelf and all the stretchers?

Put a diagonal brace to the lower legs from the top attached with wing nuts for easy removal.  G Ross

Thanks Knuttle, I'm not going to be using the handle it would just get in the way; this thing will be too big and heavy to walk around like a suitcase. Jon

I actually have a set of banquet table legs I was originally going to use for this project (they have been obsoleted due to lack of strength and being too short). I did notice that they have a folding diagonal support, but I originally disregarded that design due to the complexity. Now that I am thinking about it, it's basically just a "one strut" support with a bolt in the middle so that the two pieces can fold in on each other. That would solve my problem of length and actually be easier to assemble as well. Thanks for the nudge. Jon
