I am moving these posts over from the Layout Party 5 thread so all my posts will be in the same place. for those of you who have sen these before... sorry! Helix started!! Background: This is an N-Scale layout. It is two decks around the wall. Layout plans are posted all over the place so I won't post them here. I am building a helix to get between the two levels. The curves are going to be something like 19" radius... and there will be a 1 foot strait section on each side of a lap.. Grade works out to right at 2%. I think I will need about 6 laps.. maybe more. Inspiration for the design came from a model mag that recently published something similar. I believe I will be using the threaded rod sort of support system so I can tune the grade. Here is where the helix will be.... minus the dirty cloths!! I am using 1/2 ACX plywood ripped into 4" strips that will make up the helix. It will be an elongated hexagon shape... I guess that sort of make is a dexagon? I can get 6 pieces from each 4" wide strip. 12 strips per 4x8 sheet... so 72 pieces per sheet. The first one will be a template... The rise is about 19" between levels.. Here you can see the levels. The helix will be behind the background boards... where the pile of cloths are. I am not sure how fast I will post pictures of progress... but if you want to see the latest pics BEFORE I get them up here, plus any that don't make The Gauge cut, check out my web site here.
