We all do forget stuff so don't be too sorry ;)

DOn't take all the blame. It's quite close :)

Yes it seems a bit small, because coil was not extended with line to 
400mils (4DU) raster. You can skip much of the work by just taking the one 
in lcr.lib as a template and copy it as needed. Just open the TR60_FC and 
edit the name "TR60_FC" to what ever needed and save your library. Then 
just delete the original themplate away when you are done. Graphical items 
use 10mil spacing as a minimum (dotted line gaps), so you may need to use 
5mil raster for centered primitives. Use copy and move at larger grid 
(say 10 or 50) to manipulate. Remember to fit pins and the anchor on 
100mil (DU) grid.

Please do. My project got in shape nicely, so I'm able to commit more here 
again. Special thanks goes to KiCad team and Dick deserves a mention for 
his net classes work. The project used 20V/100mA, 330V/3A and 1.2kV/5A net 
classes :)

Now I need some extended sleep...
