Started on forward middle bulkheads
Today I started working on the forward mid fuselage bulkheads. Some of the steps required the use of a reamer, both a .311 and .375 reamer. I missed that when reviewing tools to buy for fuselage work. Luckily McMaster-Carr is open on Saturdays for a half day. $45 and 1 hour hour drive later I was back in business.
