[TowerTalk] Leveling a Trylon Base?

[Jim White, K4OJ]

Aha - a real world solution to the ever woeful tilted hypotenuse!  I 
cannot see a flaw in the theory, but:

Make sure the level is positioned along the bisector of that leg's angle 
versus the adjacent sides...

And, make sure the 1.5" occurs at the very end of the level (not a 
coupla inches in)

I have seen carpenters do a neat trick - everyone should try this... 
check your level by noting where the bubble is and then turning the 
level end for end - you should get the same bubble reading - if not, you 
have a crooked level!

i.e. is you placed your level on a shelf or table and it read that the 
bubble was exactly straddling one of the reference lines, and then you 
turned the level end for end and the bubble was not straddling the other 
reference line it is not reading accurately!

I would do this first before attempting to enhance your level with the 
block...

Lemme see, hypotenuse, bisector, angle - I have pretty much so not used 
those words at the same time in over thirty years... too bad I cannot 
remember what I had for dinner yesterday!

An idea like this could make you Rich... ooops, you already are...

Jim, K4OJ
