This is the fly press table used in the shop, perhaps overkill but it don't move, bolted to the floor, measured table movement with a machinist indicator, table top side, .001-.002 thou at the most, while bottoming out the press.
Just like a folding knife, these machines will walk and talk if not bolted down and a beefy table.
I have pondered braces, perhaps they should go the other direction, but who cares, the table don't move.

I don't know if it is heavy enough to hold the tools, shoulda made the top a bit thicker.

Thank you Gene, for sharing your table picture. I've often wondered if there is some formula that also factors in the mass of the table for optimum performance of the machine. Have you ever encountered any information about that?

No, Ron Reil's site has a lot of info on how he made his press table. I modeled mine after his. Legs are 1/4 X 3 X 3 angle iron. I used 1/4 X 1 1/4 flatbar for the braces, just because I had it, the top is two 1/4" plates welded together with about a 8" hole in the middle to drop scale through. Table height is about 36". 5/8" bolts anchor the shoes to the concrete floor. Rented a big impact drill for the holes, big is better, only took about 10 minutes.
Hope this helped.

Hi Gene,
your table certainly looks functional, regarding the braces, should the table colapse it would be due to all the braces going in the same direction so it could be "twisted" much like a soda can. When braces make an inverted V they resist sideways movement. just an observation Not a critisism! Incidentally your twist goes in the same direction that you apply maximun force i.e. downward stroke.

The main force the flypress applies to the table when bottoming out,other than the weight of the press, is a twisting action. When braces are arranged as shown, they are in tension and the uprights are in compression. If braces were run the other way, that force would put them in compression. A long brace as thin as 1/4" will withstand a tension load much better than a compression load. I have a P6 flypress on a similar stand with braces run the same way and it's also rock solid.
