Started assembly of the seat backs by first cutting the angle brackets and trimming them as called out in the print. Trimmed up the seat standoffs and drilled the lightening holes as well. Tomorrow is my scheduled hand surgery, so I won't likely get anything more done for a coujple of days. Having trigger finger surgery on my left hand this time on my index and ltttle fingers. This has been bothering me for a couple of months, so I decided to do something about it.
