We spent Friday afternoon and Saturday in Montreal, as Terry had a continuing education course there on Saturday. We had a very nice dinner Friday night, and I worked on the automatic flight test card system while she was at her course. I added a section that calculates the weight and balance, and creates a graph showing the weight and CG at take-off and with all fuel consumed.

Today I finished off as much of the left wing tip as I can do until final assembly. They I put the right console switches back in the console, carefully adjusting the amount that each switch protrudes as I installed it. I tidied up the wiring under that console, then went to screw it in place. I noted that I couldn't permanently install it until I riveted the F-804N channel that finishes of the F-804 bulkhead. I studied that part for several minutes, and couldn't see any reason why I couldn't rivet it in place now, so I got out the pop riveter and had at it.

I was almost finished riveting the right F-804N in place, when I noted three bolt holes that will help attach the canopy bow. I had just closed off the access I would need to installed the nuts. Blast!

I said a few choice words, then started drilling out rivets. The F-804N is bent into three sections. I got lucky, and found that I only had to drill out the rivets in the upper section. There is enough flexibility that I should be able to get at the nuts by flexing the F-804N inwards.

After that fiasco, I downed tools, and had a beer. Today's lesson - don't rivet anything in place until you absolutely have to.
