Went to a local store and purchased a 5.5 mm drill bit and 1/4-28 tap and went to the airport and cut the tubes for the flap push rods. Drilled each end and taped each end with the 1/4-28 tap. Installed threaded eyebolts into tubes. Installed flaps onto the wing and did some preliminary trimming of flaps next to the fuselage. Enlarged holes where the push rods travel. Will need to center ailerons and temporarily install the flap actuator to set the flaps in the correct position
