Brief Description: Drill F631E Plate to Aft Channels; Mark
Today I clamped the 2 aft canopy frame channels to piece of particle board and then centered the F631E plate and drilled it to the channels. After doing this I realized I really should have just drilled this to the workbench itself. I need to make sure the channels lie flat while I drill the inner and out flange strips to the channels. So,,,I unclecoed the channels and plate from the particleboard and then match-drilled the assembly directly to my workbench. The channels and plate were then clecoed and clamped to the bench and lie flat - with the help of my heavy cleco containers that is :-) My next step was to lay out the rivet pattern along the inner flanges. The easiest way to do this was to put a strip of masking tape along the flange, mark the ends, and then remove the tape and stick it to something flat. I then used my rivet marking fan to layout the approximately 1 1/2" rivet spacing. The tape was then placed back on the inner flange and voila, perfect spacing. I marked the edge of the flange for each rivet and then removed the tape. I drew a centerline along the length of the flange using Avery's edge marking tool. I then center-punched all of the intersecting lines.
