Brief Description: Lay-up & Section #3 Bonded

- We were concerned avout the differences in shape between the fold-a-plane & the conventional stich & glass on the strongback method. I wrote (e-mailed) Steve Rahm on Dec. 13th (the designer of the airplane) about our concerns - and included pictures of our progress.
Below is a copy from the e-mail of what I wrote, as well as Steve's reply the next morning:

Subject: Looking for Your Guidance...
Steve,
You wanted pictures – they’re attached. However, we’re looking for a little guidance and your opinion about a concern we have.
First, we decided to build using the fold-a-plane method (mounting it on the strongback former), but found we didn’t have the space to put it together in one piece. So, we put the pieces together in three sections. All seemed to go well, until tonight when we mounted the last section. The biggest concern we have is that the ¼” foam doesn’t seem to lay down on to the former in the last section. The 1/2” foam lays down okay, but the ¼” stays up about 1” – 1 ½” (at the most) above the former.
We’re wondering if this distance off the former is anything to really be concerned about. We think that if we’d just gone ahead and used the (one piece) fold-a-plane method and mounted it in the uprights – we’d never have know, or seen, a difference in the concave shape on the last 5-6’ of the fuselage…I’ve attached pictures and would appreciate knowing whether you think this difference is anything to worry about. We know we have some building up to do along the trim line, but aren’t really concerned about that; it’s something that’s easy to take care of. However, we’ve decided to stop the project until we hear from you.
Thanks a bunch! We look forward to hearing from you soon,
Eric Faber & Michael Miller
