I can't believe this was so easy and accurate. I'll never try balancing 28 lb models on my fingertips again.

One difficulty I found was accurately converting measurements on the table top (between wheel contact points), up to the fuse. I ended up using a plumb line which worked well. Seeing the more recent posts I'm now going to make all measurements from the nose, using a square to align the nose with marks on the table.

This is the first time I have had enough confidence in the measurements to start pulling lead out of the nose.

Very valuable thread. Thanks TommyWatson.
