-------------------
Jim Faughn made some 2" thick aluminum spacers bolted through the mount
and firewall to space the existing engine mount 2" further forward.
That goes pretty quickly, and with a little milling, weight can be
reduced substantially (like a large diameter hole in the middle), and
the job is accomplished and relatively easily. He probably didn't have
a mill handy, and figured the extra weight of the blocks would help with
his CG issue anyway. See photo enclosed.
Maybe I'm just lazy, but I considered redoing the engine mount when I
first got this plane and was rebuilding the engine, but I've been quite
happy to overlook the extra weight out front. I'll have to confess that
decision was partly based on the fact that the header fuel tank is
"integral" to the plane (rather than easily removable), and I didn't
feel the need to open that can of worms, required to get to the back
side of the existing 16 bolts for nut access. When I bought that plane
I thought "I'm not going to spend ANY time redoing anything on this
plane.....just keep it in the air until N56ML is rebuilt". Then I spun
a bearing just a few hours after purchase.....and while the engine was
out I redid a lot of things on the plane, but the engine mount spacers
wasn't one of them. I didn't think I'd still be flying it, 10 years
later. For more on that rebuild, see

Extending a cowling is a pretty easy job too, at least it was when I did
it, so don't fly around with an aft CG....bad things happen! See
http://www.n56ml.com/wb/index.html for my scary story on that. A CG 2"
aft of the CG limit came very close to killing me on takeoff....
