Second jig built

Yesterday I did a little shop cleanup.  Not a lot, just enough to get done what I wanted to do.  I cut a length of 3/4″ x 3/4″ pine and cut a bunch of 1-1/2″ blocks for the second rib jig.  I got the work bench partially cleared off.  The box from the R/C Cub went underneath, and the plans sheet and wings were moved to one end of the bench.  I now have roughly half the bench covered by model airplane wings, while the other half is being used to build the real thing.  ‘Murica, as my kids would say.

So, I built the second wing rib jig.  I used the first rib from the first jig and blocked everything up.  I used some plastic sheet Lisa had picked up underneath it to prevent the glue sticking things together.  When it was all finished, I mixed up 20cc of epoxy and glued up two ribs.  That’s going to work as long as it stays cold, but the glue was gelling by the time I was finished.  If it warms up at all there won’t be time to do two at a time, unless I can find a way to pre-glue the capstrip grooves a lot faster.  I wonder if thinning out a portion of the T-88 and brushing it into the grooves would work.  For that matter, I wonder if pre-gluing the grooves is even necessary.

This morning I pulled both ribs from the jigs.  You can’t tell them apart, and you can’t tell them from the other four I had done.  Any differences between the six ribs I have done are slight enough they can be removed by sanding.  So, now I can double my production rate.
