Thanks for your explanation of spline subroadbed.  You made reference  to 
Joe Fugate's video number 2 on design and construction and I pulled it out of 
 storage and watched it last night.  I had seen this before but it was a  
long time ago and I had not remembered anything about spline roadbed.
 
Thanks again - Earl Henry, Nashville

Earl,
The sub road bed on my layout is splin. It is made from wood  cut into 
strips of 1"x 1/4". The strips are laided on the risers acording to  the track 
plan. I use three splines with blocks to space the spline apart for  the 
proper width. The blocks are made from spline cut to 2" lenghts. Then  glued 
together. 

The reason for using splin:
1. No cookie cuter  plywood waste.
2. All easments are natural due to the wood wanting to stay  straight.
3. Rigidity of the splin keeps all things in alignment. Once  glued.
4. You can accually see the track arangment after the first piece of  
spline is installed. You can change at that time if somthing does not  fit.
5. Once started the spline is very fast.
6. Once done the road bed  is very lite. 

I could go on and on about why I like spline but this  should give you an 
idea.

The reasons for not using spline. The original  work to cut the spline from 
1x4 boards. Once the table saw is set with the  fence. Ripping the spline 
is quick. 

All yards are built with plywood.  

I cut my homosote in strips. For curves I cut kurfs.
