Thanks Max.
I was having trouble getting a bond with plastic gears on steel axles - a Loctite rep got me some really special primer.
We wound up knurling axles - nothing would glue those gears to metal.
I have tried the best aircraft adhesives I could get my hands on - I think I will wind up sewing the fabric before gluing. On these Walthers coaches I have been using Pliobond, but Martin says a drop of CA turns the Pliobond into really good glue.
One of the problems with these C&O cars will be the different thermal expansion between aluminum and plastic. A year worth of daily temperature changes will probably result in a broken bond. Not so plastic to plastic, so Ken's cars will stay glued, if you can handle the different height of the flute bottoms. And remember, the C&O flutes/corrugations are like Kasiner, not like the plastic stuff. You can see the difference.
