I think I have a plan for the four corners ,into the sill plates
Since I cannot get to the spots from underneath,and from above I cannot get a drill close enough to keep the drill perpendicular, I will get a 9" long drill extension and a 12" long drill.
That should get me high enough to drill a perpendicular hole through.(if I mark and drill the side bed wood first ,it will act as a guide down to sill)
