[TowerTalk] Concrete in the wrong place.

[Patrick Greenlee]

David, Of course you want to not mess up the threads so be careful with 
hammer and chisel. The steel and the concrete have different coefficients of 
expansion so heating the steel with a heat gun (I'd avoid torches just to be 
on the safe side) should help loosen the grip of the concrete on the steel 
bolts.  A wire wheel on an angle grinder or electric drill could help.  I'd 
run  the wire wheel in line with the threads not at right angles across 
them.

Best of luck on your tower project.

Hello all,So, I have a universal with the steel hinged base. It somehow did 
not occur to me to cover up the hinge area (DO THIS!) and I have just 
noticed a bit of concrete splashed around and onto the bolts of one hinge 
during the pour. I rather imagine (or is it just hope) that I am not the 
first person this has happened to. What's the best way to get this concrete 
off? Maybe carefully chip at it with a small hammer and chisel?Thanks to 
those that helped with my previous post about the angle. I got someone in 
who knew what they were doing and my base looks awesome and professional.
