It was a great time! Thanks for the invite and HIASF for helping!
I counted over 20 people on the deck stairs … SAFE ???
1.75" LVL stringers & treads. Treads mortised ¾" into the stringers with 4- ½" x 6" lags per tread. ½" allthread installed midspan to tie the stringers together and tie the staircase to blocks fastened between studs w/A35s. You could walk an elephant up those stairs (any elephant willing to climb stairs). I designed it for crowds like this.
Nice work Kenton.
