Subject: Re: [TowerTalk] what not to do in your tower
I'd be very worried that they would crack as they deform to an oval
shape under load. I'll bet that's what you'd see if you put one in a
vice and squished it. The areas either side of the weld are likely the
weakest spots, but I'll bet that rod cracks anywhere.
