Sounds good. Ti tubing would be much lighter. In .375" tube they have .050 wall thickness available. We could get it at about $1.60 an inch plus shipping. That is for the normal tube, they also have annealed and CWSR but I don't know that it would be any better for the application.
Can you cut Ti tubing with a normal pipe cutter? Can you thread it with a standard pipe threader?
And if my math is right, a 2' tube of this stuff would weigh ~3.13 ounces (~89 grams) without the caps.

I'm not sure if 50 thousandths is thick enough though - We need an engineer to help calculate the force of the impact... Which means we need the mass of the hammer and the velocity at impact. Fun!
This stuff is not cheap!!
Why not just whip the ends with another kind of cordage? You could melt or epoxy the whipping.

at my normal Ti source .050 thickness is about as good as it gets unless you go up to about 3/4" tubing, then you can get .095"
I've been checking on steel and aluminum tubing. Looks like a standard wall thickness for that is about .035"
For the hammer, I put some thought into it, I think for the lightest option that has some multi use, that 13.6 ounces could be guessed because that would be the weight of one of these:

Something like this:
pretty cool
Can use this. I machined my own but that's just meSomething like this:
May need to drill/pin it or thread the tube (that may weaken it though)
Might be heavy enough to do the job. Depends on soil conditions.I've been checking on steel and aluminum tubing. Looks like a standard wall thickness for that is about .035"

I was trying to dream up a light-weight slide hammer that could be loaded with soil, rocks or even water... this way you don't have to bring in anything heavy (or just use the water you already have).
I did a test hang today with a pulaski for one end supported by two standard stakes using dynaglide WS (the other side was my carport). I beat the stakes in with a piece of dead fall and got them in about 10" to Appalachian rock and soil. I'm not as concerned about the tool to pound them in - I figured BFR technology will most likely be where someone wants to hang.
