Hi All.
I am rebuilding a pair of front french doors 80" x 36" each door - picture a pair of glass doors with 5" x 1.75" redwood frames. I purchased rough cut clear heart vertical grain redwood full 2" x 6" x ~86". It arrived at the suppliers shop in June. The supplier (main business is custom molding) planed the rough boards down to 1.75" thickness for me. 4 months later - after sitting outside in the carport I am actually going to use them now. the wood is still dead flat in the planed dimension - beautiful! However, they are all crooked 3/16" to 3/8" over 86" length (see pic). My quest
