How long are your poles, and how long the hammock? Sounds like poles might be 8’ or shorter, or the connection holes are too far from the ends. Or your hammock’s ridgeline is uncommonly short.
As long as the ridgeline is made of strong stuff, it shouldn’t really matter much to the lay. You could add a stand ridgeline and shorten that to de-tension the hammock ridgeline.

Very interesting thread! I bought EMT tubing this week and will be experimenting shortly.
Stupid question. Everyone seems to be using amsteel for the pole connections. Would it be crazy to attach eye bolts at each end of each pole, and use carabiners to attach the poles together?
No, it isn’t crazy. I made mine that way and it works perfect. There just has to be freedom for the poles to twist a bit and the loops will do that.
If you prepare for failure you will probably succeed.
Here is the info posted on the manufacturer website. There is a table at the end of the page that lists the dimensions:

Not Stupid at all. In fact, I am amazed at how many people insist on the stand have to be connected with loose joints. The commercial Tensa has specific design and production needs that drive it's design that way. I however prefer the solidness of the bolted connection to hang the hammock from. It transfers the load to the poles in a more consistent way.
That said. If the poles are solid then you can only bolt one of the two joints. Either at the Apex, or the ground you cannot do both at the same time.
Another lesson learned since this thread was started, 1/4" Grade 2 hardware is not strong enough. It bent like mad and I replaced it with at least grade 5 steel bolts. The nylon spacers are a must to prevent you suspension from binding and getting pinched.
If you make the collapsible version then you can bolt all four joints, as the needed torsion is relived in the pole joints. The improved DIY TENSA is here: Link
Hope you make one.
We just had a guy from the UK asking this in the last couple of months...
Anyway, I think you need to look for something like 6700-25L4. conduit. Believe that is the 1" EU standard. But either way here are the measurements of the pipe typically used here.

Note the 1/2" or 13mm is way to flimsy for this application the 20mm would be good for applications up to ~2500mm long. Above 2500mm I'd use the 25mm pipe.
This is at least a starting point. If you find a good spec let us know. If you want, the buckling analysis/ margin of safety information is on page 5 post#49 of this thread.
