[TheForge] Setting Railing Posts

[Woolley]

Greetings,

For anyone setting railings in concrete, brick, stone etc., how deep are 
you setting your railing posts?  I have been setting mine 4" deep but I 
was just wondering what others were doing. I use hydraulic cement,  a 2" 
core drill for 1" posts, but have recently considered buying a carbide 
tipped 1 1/2" for this.  What are you guys using?

Regards,
Bill Woolley
