[TowerTalk] Re another w51

Sat Jun 10 13:12:39 EDT 2017

While I suspect there is no confusion in the ongoing current banter about 
the Tri-Ex W-51, it might be well to remind all that the W-51, as I 
recollect, differs structurally from the later WT-51 (one of the crankups I 
have).  I don't have the specs for the W-51 but was there not a difference 
in the wall thickness of the vertical section tubing, the W-51 being 
thinner, thus reducing the load the tower could handle?? Seeing so many of 
these being up for sale or in use it might be useful if someone could post a 
chart that differentiates the important differences between the two, 
including whether the base mount dimensions also differ. This would be a 
useful tool when looking a load capability.
