[TowerTalk] Digital Angle Gauge

[David Gilbert]

There was a message thread here a few weeks ago about how to plumb a 
tower, with several suggestions ranging from using a plumb bob to a 
laser level to a transit.  I've been installing the base for my new 
freestanding tower the last couple of days, and since the legs taper 
toward the center I needed a fairly precise way of making sure all three 
base legs tilted the same amount.  I remembered that I had previously 
bought a digital angle gauge to use for setting blade angles on a table 
saw, so I dragged it out and it worked great.  It has a magnetic base 
that attached easily to the steel tower legs, and the rated accuracy is 
0.1 degree.  I have no way of verifying the absolute accuracy of the 
thing, but I did spend quite a lot of time checking the repeatability 
and I can confirm that it is indeed within +/- 0.1 degree.  It really 
made the job very easy.

I'm sure that there are several similar models, but the one I happen to 
have is made by Wixey and it is available from several online suppliers 
for less than $40.

For what it may be worth ...
