HS Rear Spar

Time: 4 Hours

The squeezer dies that I ordered from Avery Tools arrived this afternoon. They are a 1/8″ flush and a thin 1/8″ cupped die. I needed these to give me the clearance to properly squeeze the rivets.

20130412-205215.jpgI see a lot of other builders posting photos of them actually working on their RV’s so I thought I would do the same. I just downloaded an app on my iPhone that has a camera timer, propped up the phone and started riveting. Here are a couple of me looking like I know what I’m doing!

20130412-205700.jpgI learned a valuable lesson today: you always need to re-adjust your squeezer settings, the amount that the rivet is squeezed, when you change what you’re riveting! I went from the stiffeners to the first hinge brackets without adjusting and squeezed the first rivet way too much!

20130412-210111.jpgOnce I got that done I finished up the rest of the hinge brackets. The center bracket gets attacked with 4 bolts.

First Assembly

Time: 1 Hour

With the primer dry I started to do a little assembling. Then I noticed a step that must have skipped over in my match drilling. The 4 holes that allow the HS-411 bearing/hinge to be bolted to the HS-609 stiffener and the HS-603 did not get drilled out to a #12! Oops, not a big deal, and I just did that step now. Then I deburred those holes and primed them. I’m waiting for a 1/8″ flush set and a modified 1/8 cup set from Avery Tools so that I can squeeze the rivets on these pieces. Hopefully they will be here by the weekend so I can get some riveting done.

Priming

Time: 2 Hours
When I got home from work last night I decided I had enough time to jump in on priming the ribs of the HS. I’m using Dupli-Color self-etching primer. It has a lot of good reviews and I really liked how it looked on another builders parts so I followed suit. I will prime all the parts over the next few day and let them cure for a few days and get to riveting.
