Still messing with the firewall fitment - 6 hours

After quite a number of small build sessions in the evenings, lots of fitting and checking, trimming the longeron(s) and repeat the process. But I seem to have everything figured out. Its taken quite a lot of time to get things to fit right. Tip: the best method I found was to start fitting the longerons to the firewall using the AD4 rivets first.....Then cleco the side skins to the longeron. It doesn't work well if you cleco first and then try to slip the rivets in. Its a very tight fit for everything.

The last little item before drilling the firewall that I notice is that I have one hole each side that has a questionable edge distance issue.

I've put up a post out on the Van's forums to see what the consensus is as not many people note this item on their build-logs, and I couldn't find any other pictures of this area on other builds. Looks like I might be the first one?

Called Van's the next morning and the advice on my particular edge distance issue was to build-on. Technical support was extremely helpful offering additional advice on recommended cowling attachment. I won't dive into the details for the blog but we had talked about sky-bolt fasteners and a good practice is to tighten up spacing of them along the bottom. Once again, Van's is 10/10 for service and support! 

Here's some misc. pics of me messing with the fit over the last couple days so you can see the fit.
