Surface patch

1.Surface patch====

what we need;

universal rivet ms470, sketch of the patch and panel, sand paper, tools; rivet gun with straight sets, deburring tools, gleco, filling tools ,bucking bars, fastener pliers

what we do;

calculate the rivert including Ed(edge distance), Rd( rivet diameter),Nr(no of rivet),rl(rivet length).Then sketch onto the sheet of paper, make the photocopy, patch it onto the 2024 sheet metal. When done cut it through its size and shape of the patch and skins.

Filling the edge of the sheet metal, make the hole for the riveting on both skins and patch. Gleco by using sheet fastener pliers.

Cut the bottom of the rivet by using the rivet cutter. Say if the rd which is 3/32 so must add 2 plies of bottom steel of the rivet cutter to make it cut and firm to the patch and skin . Put that rivet into the hole of patch and skins and begin to riveting by using rivet gun and bucking bars. The shop head that was shaped from the pressed of bucking bars must be ½ to the original length of the rivet (that is the length of the rivet behind the panel).

Next----> will be on flush patch next time
