Well I am off building my helix to get to the second level of my layout. I am using a technique I read about in model railroader. In fact I have seen this style of construction at least two times that I can remember.
It is a simple way to build a helix. You cut out the subroadbed with a jig saw, and use spacer blocks to create the seperation between levels. Once the intial grade has been achieved (2% for me), the next levels will adopt the previous grade as you go along. I still think this is one of, if the, simplest techniques I have ever seen.
The hardest part about this project (for me anyway) has been creating the 2% climb with the risers on the first turn of the helix. I had no success with the helix in place. I have had to go with the risers alone creating the 2% grade using my lelev and the %/degr tool I have bought form Micro Mark (fantastic little device I might add).
As usual for me, a little couple of hour project has turned into quite the frustrating nightmare. But going from one riser to the next in this fashion has given me a steady rise that , when finished, should give me a good starting point for the bass of the helix. I can go along and make adjustments when I finish.
I am hoping that I will have some good noews tomorrow night.
