Helix Part 3 and First Track

G'day all, I have been busy painting the bench work for the helix and working out track placement for the lower level. I have also taken my time to get the start of the helix just right to make it a lot easier to construct once the first level is complete.

The photo above shows the base board for the inside track on the helix to exit and access the lower level as you can see I have also cut the slots for the helix support.

I have just finished painting the road bed for the helix and in the process of working out the heights for the incline in the shots above and below. You can see the start of the incline at the gap near the blue screw driver.

To make sure the helix has a rock solid base and makes it easy to build the next layers I cut a 1800mm length of timber on an angle to match the grade of the helix. I then marked the level of rise on the timber and placed them at the corresponding locations under the helix then checked the slope with another piece of timber from the same cut.

The first track on the Boyne River Subdivision is the inside loop leading to the lower level I had to do this first because the the helix will spiral over it preventing easy access. The out of sight track will be Atlas code 80.

Here is a tip for you, If you are cutting track with a Dremel tool get the larger cutting wheels as this will allow you to make clean straight cuts unlike the smaller wheels that you have to angle because of the Dremel body.
