Spars Continue

In between the various family activities with the holiday weekend I continued working on the spars.  Much of the work is monotonous.  After writing my last post I dug in a bit deeper and found a different way to do things.  I match drill everything.  Counter sink the #40 holes.  Then I place my “jig” and CS my #19.  This works for me.  There are 4 surfaces to do, both spars top and bottom.  There are 30 attach points / side, 120 in all.  240 #40 holes to cs and 120 #19 holes to cs.

Counter sinking makes a huge mess.  There are aluminum chips and filings everywhere.  They get in your shoes and in your hair.  Here are a few pictures of the mess.

I’ll be out of the shop for a few days traveling.
