Hi Doc,

I'm just putting a UCD together right now, and I noticed when I bolted the engine mount onto the firewall, the covering on one of the sides of the fuse started to wrinkle up! Is it normal to do this (from the stresses of the mount against the firewall), or does it sound like I have a potential problem on my hands as well? Oh, I also have 2 washers behind both screws on the left side of the mount, as this seems to be what many people are doing for side thrust.

I was planning on dripping some epoxy along the firewall/fuse joint (on the inside). But there isn't really anything else you can do, the way the UCD is built. There isn't enough firewall to pin it, and even with the hole I cut in my cockpit floor, there isn't enough room to get inside to add gussets of any kind.

What should I do, if anything?

Mark
