Had some time this weekend to work on two 914's. My son wants to get his running and take over to CA. It's now in the garage on stands and getting prepped for some minor maintenance, gas tank replacement, and maybe fuel lines.
I dug out the Engman reinforcement kit I bought for the inner longitudinals in the cockpit. There are three pieces that cover three sides - left, back, & right. I wanted to check the fit for the left side and see whether it would block access to the patch I need to weld. . .
Yep, it does.

I need to be able to get a copper backing plate behind the weld when working on the thin flooring material. Not what I was hoping for - but gotta be done that way.
Here's shots of test fit for left, back & right sides. I'll get all the rust on the floors along these pieces cleaned and treated before starting to weld - since the corners won't be as easily accessible afterward.
