05/08/2007 - Rear Spar

Its all about getting the strengthener bars sorted first using the scotchbrite wheel.  It did not take too long at. These were then fitted to the spar itself and match drilled down into the jig.  I must of counted the eight hole for the #19 holes about ten times !!!  These holes are drilled to #19 for the ribs to attach to later.

I then made a start on match drilling the brackets for the elevator.  I have not riveted the central bushed assembly as yet as it needs priming, so I will wait until there is a little more to do than just a bearing.  Once its riveted I can drill the holes for the bolts.

so with the rear spar sorted for the time being it was on to the front spar.

Front Spar

Some match drilling required with the strengthener bars for the front spar being careful to only drill the holes that are stated in the plans.  The plans then ask you to shape the bars as in the picture below.  Well its been a hot day and I was sweating buckets after filling down the edges.  The ends were rounded with the scotchbrite wheel.  Next comes the bending of the flanges to 6 degrees, but I decide that's for another day !!!
