Tight radius work

Tight radius work

Really tight radius curved stairs are difficult for bending handrail.  Recently we had a very short, but extremely aggressive bend in a stairway where we helped the customer install the handrail.  To achieve the tight bend we did a process of moistening and pre-bending the handrail.  Because of the extreme amount of moisture that we applied to the handrail we used Titebond 3 glue to be certain we had a waterproof glue hold.  We pre-bent the handrail by successively bending the handrail farther into the radius over a period of 2 days.  We pre-bent the handrail even farther than the final radius which reduced the spring back when we finally glued the handrail
