A couple of recent projects produced on the machine - the Metro Rod sign was installed yesterday, Rennie Fabrications was done a few weeks ago. Both signs feature flat cut plastic lettering

Good stuff! A fabrication firm hiring a fabrication firm to make their fabrication sign? A fabricated story, methinks.

Ba dum dum shing! :D

Hi Phil, would you consider expanding on your truss rod? Is it simply a 1/2" threaded rod installed and tensioned just under the deck/table? I did not see a washer or any method of distributing the pressure. Would you advise some sort of washer or plate? I very much appreciate the help.

When I added a truss rod to my book build I just used some washers on the end of the threaded rod, but I would recommend using a long narrow plate and maybe two truss rods to spread out the pressure. even with a large fender washer the pressure ended up hauling the washers into the wood.

I would say you need a washer to prevent the MDF from compressing. However, my machine is skinned with an aluminium composite material which helps to spread the load. I did consider fitting two truss rods as rob has suggested - but found in practice one was sufficient to eliminate the sag.

Let me see what I can do with a pair of rods at 1/3 and 2/3 the width of the table. I guess my question is, does the truss "pull" the load, or does it "push" the load? It seems in my mind like tightening a tightrope, but by using an interior rod instead of exterior anchored turnbuckles. Is my understanding correct on this? I can cut a couple of pieces of 1/4 x 1" flat steel or even angle and drill them to accept 1/2" rods, but am I spreading the load or compressing it? Also, a double rod setup seems to allow for correction. I wonder if I am gonna rip the cross-dowels out of the mdf top. As suggested, I am going to mount a few pieces of aluminum angle with countersunk screw holes. They can straddle the truss rods.

I will try to get photos of what I attempt.

Finally-- Phil, your work is fantastic. I really like the style of the sign for the stove shop. Thank you for answering my message,
