Fuel Tanks 10 (1.0 hr)


I didn’t get a lot of time in the shop, but I was able to get some outstanding tasks completed.  I dimpled the remainder of the left skin and drilled the holes for the flop tubes.20140119-192318.jpg

I bought some tools for tube work.  The springs allow you to bend tubing by hand.  The Roto flaring tool (red handle) allows you to flare tips to the required 37degrees, and finally the blue handle Imperial 470 can do perfect bends of up to 180 degrees.  I will use these for the fuel vent. 20140119-192328.jpg

There’s one problem.  That one rivet hole under the elbow.  Its just barely outside the minimum distance required.  But….20140119-192345.jpg

Here’s where its a problem.  I won’t be able to tighten the nut all the way down.  I will have to countersink this rivet and install a 426 flush rivet instead.  20140119-192356.jpg
