Fuel Tank Support Framing

I removed the alignment jig for the two pieces of white oak being framed in. 

The below picture show the results. One of the four corners needs some epoxy injected into a void, and the all could use a quick pass with a grinder. 

Forward framing. Starboard side on top, port side below.  The flange on the left side of the picture was cut back today also. 

Aft piece of tank framing,  starboard side on top, port side below it.  Lower photo show the air pocket. That will be drilled and filled with epoxy. 

Generally, you don't want air pockets, except perhaps between bulkheads and hull tabbing, to avoid hard spots.   Typically I will grind out air pockets and re-tab, or occasionally I will drill holes and inject epoxy.  In this case I will probably drill it out, fill with epoxy and after grinding decide if I want to add more fiberglass to these tab.  Each of these had a fillet of torn up mat, followed by a layer of mat and two layers of stitched mat.  That makes for a solid bond and a prepared surface.
