Wing Spars 12 (2.0 hrs)
For some reason, I was thinking that I could prime the ribs at the same time as I did the spar components. As I read the instructions again today, I realized I was mistaken. It was best to get the spars primed and riveted so that I could cleco the skeleton together, match drill and then prime the ribs. So thats what I set about to do. 
Here you can see my method for holding the spars. Some old hangers did the trick nicely.
Squire loves priming!
I did have some trouble with my HVLP gun today. It keeps not spraying paint. Afterwards, I did a complete tear down. I cleaned each part thoroughly and applied some silicone lubricant in some key areas that I think were binding slightly. More importantly, I think I discovered the problem. The paint reservoir has trouble sealing, which if your not careful means you can very easily spill that expensive primer. Its a HF tool that works great, but like a lot of HF things, there is always something!. To fix the sealing issue, I applied some vaseline to the threads of the plastic cap. The lid seals great now. I noticed the vent was clogged with primer. I have never opened the vent before, but with the leaky lid I think the reservoir was able to equalize. After unclogging the vent, and reassembling the parts I gave it a test run with some MEK and it seemed to work fine. She’ll get a real test very soon.
