{S-Scale List} Homosote Board

[David Engle]

I have a quantity of 7/16" Homosote board that I would like to saw up into 
strips 3 in. wide for roadbed in yard area, vs. mainline setting.  Some will be 
straight, some will go on curves no less than 40" radius.  How deep into the 
board width should the lateral cuts be, and what spacing between the cuts 
should be best?  Thanks Much.  DJE
