I did my first radius staircase this year, actually it was two of them on one job. Looks pretty good. I'll have to show pics as soon as possible, just not very good with computers. Anyway, the block was easy to place I found out, because your only seeing the side. I had a heck of a time with the caps though. Turned out good, but it just seemed so time consuming!!! Any tricks to lessen my man hrs. and pain in my back from lifting and cutting and placing over and over, over? Dont get me wrong it was worth all the sweat and hard work, my client is very pleased. Just very frustrating at times. Look forward to your thoughts.
