Rib Home Stretch - Again

This is what the stack of full cross-section ribs looks like.  The foot-rule is there for scale.  There is something just over 1,000 gussets in this stack.

These have all been inventoried and tied to the drawings.  They are stacked in order with #1 Left on the bottom, then #1 Right and so forth.  One little task I do need to do is go through them all and make sure the tops and bottoms are smooth.  There are incidents where gussets or glue drops are "proud" of the capstrip.

The rib jig has been modified for fabrication of the two tip ribs, one for each wing.  These ribs have a somewhat narrower cross section than all the others.

Yes, I built this jig over the full size drawings supplied with the plans.  I figure this will work just fine for the two ribs.  I wouldn't do that for all the others.  If building wings again (not likely) I would use the same procedures I have used for all of these ribs.

The nose block and tail block are in place ready for the capstrip.

After an afternoon...


Side "A" of the first tip rib is all glued up.  Depending on the weather, Side "A" of the second tip rib and Side "B" of the first one will be glued up tomorrow afternoon.  The weather is a factor, because if good VFR conditions exist, I will go fly the C-150.  :)
