HS Spar Pg 08-11

Finally able to rivet the 10 front spar 470 rivets. The trick was setting the 3x gun correctly with the compressor. 90 psi at compressor with a 30 PSI drop while pressing gun trigger & turned down at the gun brass regulator & using a 10.5” straight rivet set. Elevating & strapping the assembly to the table definitely help. I also fabricated a coupon with over 20 holes to practice setting #4 rivets over & over. I then was able to move on to riveting the skin to the spar.
